hello, this is bbc news. the headlines... germany bans almost all travellers from the uk because of the rise in cases of the indian variant of covid—19. the vaccine programme rolls on in england.

more than a million 32 and 33—year—olds can now book their jabs. the first convoys of humanitarian aid have arrived in gaza, hours after a ceasefire between israel and palestinian militants came into effect. it's understood that ministers are to give the bbc a chance to introduce its own changes, in response to the damning report on how martin bashir obtained his panorama interview with princess diana more than 25 years ago. animal rights protesters have been blockading four mcdonald's distribution centres in the uk to stop deliveries to the fast—food chain's 1,300 uk outlets. mcdonald's has now apologised to its customers for the disruption. and, get your best sequins out, the final rehearsals are done and the pyrotechnics are ready — the eurovision finalists compete tonight after a pandemic—enforced break.

now on bbc news, it's time for click. this week, we're shooting for the stars. we're playing the biggest games in town, literally. and shh! whispers: there's a comedian trying to sleep! welcome to click! hope you're doing 0k! this week, we're going to be talking a lot about taking photos. so, lara, you know we have all been looking for new hobbies to help fill the time during lockdown, yeah? i've been very busy colouring in with my eight—year—old. 0h, lovely! so, she's got her colouring—in book

and you've got an adult colouring—in book and you sit next to each other, do you? no! i only do the children's ones because i think the grown—up ones are too fiddly! anyway, what have you been doing? chuckles. well, let me tell you, you know those amazing photos of the stars in the night sky that you can get by taking a long—exposure photo? well, i've kind of been getting into that, and it turns out that astronomy as a whole has become a much bigger deal in the last year. i suppose it's something you can do in your back garden when you're on your own and can't go out. exactly! so you might think that you'd a big dslr and a telescope to get those kind of shots. but no. turns out you might already have everything you need in your pocket. so, i wanted to find out more about this, so i asked tv host, space journalist and author sarah cruddas to try a bit of astrophotography on her smartphones. it was looking up at the night sky as a child which inspired my lifelong love of space. but whereas in the past,

capturing images of the night sky required expensive kit, now all you need the latest smartphone, a bit of luck with the weather and enough time to set up before it gets dark. the latest generation of smartphones have a few low—light tricks up their sleeves to make getting those insta—worthy night sky photographs a lot easier. i'm testing out four of the latest smartphones. we've got the huawei mate a0 pro. the samsung s21. this google pixel 5. my iphone 12 pro max. and as for this, don't worry about it just yet! because we'll be taking long—exposure photographs, the most important extra you'll need is a tripod to hold your phone steady. and the other really important thing

is to go find somewhere that doesn't have too much light pollution. you can always have a look online for dark sky recommendations near you. then all you need to do is wrap up warm and wait for night to fall. in fact, you might not have to wait until it's fully dark before you get your first shot. if it's up at dusk, it's actually easier to shoot the moon against a blue sky rather than a black one — that way, your phone won'tjust turn it into a white blob while trying to compensate for the incredibly dark sky. often when you think of astronomy, you think of expensive kit but to be honest with you, if your phone isn't enough, if you want to get slightly closer to these astronomical objects, you need a pair of these, not a telescope. i am such a fan of binoculars, they are lightweight, you can carry them around, you can take them where you want to be, and it involves less setting up and literally it is a case of holding your smartphone up to the binoculars to get that perfect shot. there we go, i've got it. it is a bit tricky but if you want to get really close—up

pictures of the moon, it might be worth listening to a proper pro. a problem with trying to attach your camera or get your camera in the right place to look down the eyepiece of a telescope is holding the camera nice and steady over the eyepiece. so, there are now devices — in fact, i've got one here, there we are — it's like a little clamp. this bit clamps over the eyepiece of the telescope and your phone fits in here. which is brilliant, it will keep it really rock steady on the eyepiece and then concentrate on the picture. it is, as you can probably tell, insanely dark. of course you are going to need a torch, but so you don't dazzle yourself or ruin your night sky vision, here's a top tip for you — use a red light. in fact, it's so dark that we have chosen to record this entire film using a sony a7s mark iii, which has very impressive low—light credentials.

it is a full moon, but apart from that, we have only used an artificial light for a handful of shots — we will tell you which ones on—screen. just look at how much our normal tv camera struggles in comparison. 0k, time to see what these phones can do. click. this is the iphone 12 pro max. it's not bad for starters. and this is another tip — if you are worried that pressing the shutter button will wobble the phone, you can get a very cheap bluetooth remote clicker like this one, or you can even use the volume control on your headphones as a remote shutter button. the iphone and samsung don't have specific astrophotography modes, so i'm going to go into full professional mode on the s21 and set a long exposure going. and the result is... oh, wow! wow! do you know what? i even need to do slightly less exposure. it looks — to be honest with you, it looks like a nuclear bomb has gone off, it is so bright! if you play around with the settings, you can get some

really lovely shots, but the next two phones remove the trial and error with full astrophotography modes. hold still for two minutes and 48 seconds. the google pixel 5 decides for itself how long it needs to run for. and for this shot, i'm also using one of pete's other photography tips. if you take pictures of stars with no context around them, they are just dots in your photo. there is nothing better than actually putting in a bit of artistic composition and adding in foreground objects, because it gives everything a beautiful context. this is incredible! it is a really, really bright, really powerful image i would say of the night sky, but it almost looks like daytime and i feel like i am a professional photographer, even though i am just using a setting on a smartphone. one thing to bear in mind is when the moon is full, the brightness will make photographing stars

rather difficult. we actually got some better shots a few nights later, before the moon was up. and now, to the huawei mate pro 40, which has something called light painting mode. this simulates a very long exposure shot by taking one photo every few seconds and stacking them together. the results are stunning. and itjust makes you realise that we are on this object that is moving, that is hurtling through space because, you know, you see how far the stars have moved. i think that is the best astrophotography picture i have ever taken with a phone, if i do say so myself! it is quite incredible, really. i'm really impressed with the phones, but now i'm going to try something that is comparatively out of this world. the stellina telescope uses the same technique of stacking lots of images, but on a very different scale. it has been designed in consultation with astronauts, and former nasa

astronaut terry virts is the telescope�*s brand ambassador. the stellina is kind of like being in space, because you can see the planets and pick them out in space, but they are just small dots. and the stellina optics are sort of the same — it does not have a big zoom lens that really zooms into planet, but what stellina does let you do is see these deep sky objects, and in space it was kind of the same thing — you cannot zoom in with your eyes on the planets, but you can see these giant clouds of hydrogen in the milky way, or you can see nebulae with your eyes. 0nce powered up, the stellina orientates itself by looking around for familiar stars and constellations, and the accompanying app will give you a list of deep sky objects to choose from. so, we have got to choose from the m13 galaxy, m51, m82, sombrero galaxy, double cluster. let's do m13, the hercules cluster. it will then track the chosen

object across the sky, building up an image which it sends direct to your smartphone. do you know, i have done astronomy since i was five years old — i remember i had a little children's pair of binoculars — but this is the most high—tech thing i have ever seen. i've done it! so, this is my photograph. it's taken it for ten minutes of the hercules cluster. you cannot even see this object in the night sky, and this image has brought up not only the cluster, but more stars than i can see with my own eyes. it's — it's really incredible to think how much technology has evolved since galileo looked up with his telescope all those centuries ago, and now we have these science fiction—like smart devices which capture images of the night sky. in order to get the best pictures, you do need some perseverance and patience, but the results really have been worth the cold.

sometimes, though, it isjust worth putting your phone down and taking in the majesty of it all as we hurtle through the universe on our one tiny ball of rock. brilliant! that was sarah cruddas. how amazing were those pictures? incredible pictures, and it's amazing to see what our smartphones can do that most of us will never actually use them for. right. and over the course of the past year, some people have got into new hobbies. others may have been busy sorting things out around the house, like maybe going through some old photos. and in fact, i have something here that could be very handy for that. this is a gadget for digitising old negatives, so you can either save them in your phone or you can print them. right. 0k, how does it work? it is simple to use, but it is a bit fiddly. you've got to download the pictoscanner at first

and then turn the light on... slip your negative in here. line up your phone camera with the hole. and then, you are ready to go. i see, so it is reversing the colours in the image — it's showing you the positive of the negative in a live view, yeah? that's right, then you've just got to snap it. that is a striking photo, by the way. that's darth maul, if anyone�*s asking. it is, and it's bright, so it seemed a good one to test as the colours really pop. and after a bit ofjiggling the device about, it works. it is not perfect, but it is largely made out of cardboard, and it does only cost 35 quid. is that you under the make—up, by the way? no! all of my old pictures are way too embarrassing! i think it is you under the make—up. hello and welcome to the week in tech. it was the week google announced it has three billion

active android devices. it also previewed a skin condition diagnosis app and a 3d video chat platform, all at its online io event. a probe investigating if amazon has exploited its market dominance was launched by germany's anti—trust watchdog. and crypto scammers posing as tesla's elon musk made more than $2 million — that's £1.11 million — injust six months, the us federal trade commission has said. ada, the robot artist named after computer programmer ada lovelace, opened its first major exhibition. the robot, which uses al to create self portraits and speak, is being showcased at london's design museum. an electric aircraft for suburban to city commuters was unveiled by germany's volocopter. the four—seater can take off and land vertically, and has a range of 62 miles, say its makers. however, it is a smaller two—seater model the company aims to launch first, by 2023.

and finally, a robot can now scale stairs without computer vision to guide it. feats like this usually require ai sight, but this two—legged bot has been trained in a virtual simulator to operate blind, meaning it could be used in dim light orfog. it's definitely going up in the world! now, after months of shutdown, cinemas here in the uk are finally reopening. and while they wait for all of those big blockbusters to be released, they are looking at ways of making money in the meantime. so, how about this? how about bringing video games to the biggest screens in town? marc cieslak has been finding out more. the popcorn has been purchased, the house lights dimmed, but instead of preparing

for the latest blockbuster trailers, i'll be grabbing a game controller and firing up a console on one of the biggest screens here at the cineworld in london's leicester square. there's big, and then there's that. this screen is 2a metres across, which dwarfs even the largest television. at the moment, though, its grand scale is simply highlighting that i need to spend a little bit more time practising at mario kart. after months of cinema closures, blockbuster cinematic releases have been on hold for the last year or so. the movie business has taken a massive financial hit. in 2020, the global box office was 71% behind where it was in 2019. the box office in the uk last year took around £322 million,

which is a good 76% behind where it was in 2019. so it really was a sizeable hit last year. finding new ways to make cash has seen cinema chains turned to the world's biggest entertainment medium, video games, renting their screens out to gamers. we haven't been able to see a superhero movie in an auditorium like this for the last year or so, so it is really cool to be able to play a superhero on a screen like this one. and as miles morales�* spider—man swings across manhattan's skyline, the action is so epic that it provokes a sense of awe and vertigo in equal measure. yeah, i think it is obviously incredibly important that we as a sector, as an industry and as a business innovate right now, we need to pivot, like most businesses.

in terms of gaming, it is a new offer that we have seen quite a lot of demand for, to be honest. obviously we have the biggest screens, the best sound, dolby atmos etc, so yeah, it has definitely become something of interest to customers. i think, particularly now that they want to leave their houses for new experiences. everybody�*s been stuck indoors, now they want to get out and about and experience things in the real world with their families and friends. it costs £119 to hire a screen like this one for up to 20 people for two hours. gamers can bring along their own consoles, or for an additional cost, they can choose to play from a catalogue of titles on a range of machines from vintage consoles like the original playstation, to newer consoles like nintendo switch and the ps5. i think it is really interesting, i think it should hopefully have a positive effect in the sense that they will bring more revenue into the cinemas.

if you look at multiplexes, they have ten or 20 screens with up to six shows a day on those screens. so your average cinema is showing somewhere between 60 and 120 screenings a day. and unsurprisingly, quite a few of those are often empty, all the cinemas are doing is seeing that they have that empty space and finding other ways to utilise it to make money. while the money generated from initiatives like this one is unlikely to make up for a year's worth of lost revenue, it demonstrates that while cinemas wait for the delayed blockbusters like the latest bond movie, no time to die, to bolster the box office takings... you can imagine why i've come back to play. ..plans like this one mayjust be what picture palaces need to keep in business. that's—a finish! laughs. that was marc. now you know over the years i have tested a fair few sleep gadgets. yeah, you have, in fact i remember the very first report you did for us

all those years ago was done entirely from bed, wasn't it? it was. well, things have moved on, in more ways than one. those devices used to be a lot about tracking how much sleep you got, whereas now they also focus on bettering it, especially for those with sleep disorders. and one of those people is comedian dom joly, so he has been putting a few of the latest to the test. # moon in the night sky, how brightly she shines... snores. hello, i am dom joly and i am a comedian and travel writer, and i am in my bedroom. why am i letting people film in my bedroom? well, i've got sleep apnoea. it was a shock because i have never had anything wrong with me, something like sleep apnoea, i couldn't even spell it. so i looked up, it is incredibly common, actually. it essentially means that

you stop breathing on a lot of occasions through the night while you are asleep. and the main way you can tell you get it is snoring. this is how i got diagnosed — my wife used to constantly tell me i snored. i was stopping breathing i think up to 90 times a night for up to a minute at a time, and that is insane. i mean, i thought i slept quite well, but it appears i haven't actually got any sleep for the last 20 years. and if it's not diagnosed, if it's not treated, it can lead to terrible strokes and very bad health. and since then, i have had to wear... it's normally linked into a pipe, but i have to wear this every night. hello, ladies. hello. obviously it's a very sexy look, but it's just a bit of a drag, it really is. so i'd be very interested to see if there's anything else on the market that can deal with my sleep apnoea. this is actually a smaller version of the thing that i have by my bed, but basically i still have to travel around with this machinery, piping.

what i'd really like is something else, either to get rid of sleep apnoea or at least help me control it without having all this equipment. we've got three things here that i have been sent to have a look at. and they are not ideal, i will be honest with you. the first one, this is a thing where you... everything seems to involve making you look slightly ridiculous in the sleep apnoea world. i don't know if it's just, that's their thing, but whatever. this one, you stickjust above your chin, and basically turn it on and you go to sleep. and when you wake up in the morning, it links to an app and tells you essentially what sort of sleeper you are, how good a sleep you had. it shows where you are getting good sleep, where you are not. it also sort of tells you whether you are a late—night, early person. it is basically asking you to regulate your sleep and it's teaching you more about your sleep. so it is analysis. to be honest, if you live

with someone as i do, my wife analyses my sleep pretty regularly. "you're snoring, shut up, stop moving around". she gives a detailed, i mean, i wake up in the morning and she's about to punch me in the face for something i have no recollection of doing. the second one, attach these pads to your chest, again you go to sleep, when you wake up in the morning, you send off your results to somewhere in america, and they send you back a detailed breakdown of your sleep patterns. and also a shopping list of things they think you should buy. it sounds a little bit like a sleep apnoea amazon, which is kind of urging you to buy stuff that i am not sure you need. actually that is a worry, because it is not cheap, sleep apnoea. my machine by my bed is from the nhs, but this travel one i had to buy, that was 900 quid. if there was something cheaper that worked, i would absolutely love it, but it's got to work. this one, i think, is probably the most interesting because it actually does try and do something else. and what it is basically trying to do is retrain my brain. which i can tell you straightaway

is a tricky thing to do, because i am very stubborn. this is called neuro feedback. i'll put it on, because obviously you have to look ridiculous when talking about sleep apnoea. and you put this on your head, and there are electrodes, it sounds terrifying and sort of feels it a little bit. they are sticking into bits of your head. and again, they send messages around your brain. and the idea is that over a series of sessions, you try and retrain your brain and the way you sleep. did it work for me? i have to say i did ten sessions — nothing. but that doesn't mean it's not good, i'm sure it might work. my daughter does neuroscience at university and tells me this is actually a thing, but she thinks i might be a bit too stubborn. but i quite like this, because at least it's trying to do something different. the truth is that if you really want to get rid of your sleep apnoea, i think you've got to start eating a bit healthier, maybe drink a little less, quite a lot of exercise, lose some weight...

i mean, i know that, but i want the magic thing. but until then, i'm just going to take my travelling contraption around, and i have to live with that until someone comes up with something that really works. # now all the world's asleep... that was dom joly. i tell you, lack of sleep, insomnia, sleep disorders, they are a complete nightmare. i am so lucky that i don't sufferfrom insomnia. but whenever i've tested sleep gadgets, i end up struggling to sleep because i end up focusing on them, which obviously completely defeats the purpose. laughs. too right, i see what you mean. well, i am afraid that is it from us for this week. as ever, you can keep up with us on social media, find us on youtube, instagram, facebook and twitter at @bbcclick. thanks for watching, sleep well and we will see you soon. bye bye.

after yesterday's strong winds and heavy rain, the weekend's weather is looking a little bit more optimistic. certainly today we have drier and brighter weather than the last few days, and crucially it is less windy. still a few showers in the forecast, so it won't be dry across the board, but some usable weather between any showers. here is the area of low pressure, and all that cloud that swirled around it yesterday now clearing towards the east. that was what brought us the really heavy rain and strong winds. low pressure still close enough to bring breezy conditions around eastern scotland and eastern england, but with higher pressure starting to build from the west, things will improve through the day. sunshine initially for scotland and northern ireland will filter its way further south and east across england and wales

through the afternoon. still a few scattered showers bubbling up here and there, especially for parts of central and eastern england and northern ireland as well. temperatures about ten to 15 degrees, so in the sunny spells between any showers, some people miss them altogether, it will feel reasonably pleasant. into the evening, some heavy showers initially towards the east but they will ease away overnight with things becoming dry for most with long clear spells. quite a chilly night, could be a touch of grass frost across parts of scotland and northern england. just about frost—free further south. during the day on sunday, after that cool start, there will be more rain, it moves slowly from west to east. so some dry weather before it arrives, breezy later in the day because another area of low pressure moves in. quite a few isobars wrapped around that area of low pressure as well. but for the bulk of the day, quite a bit of central and eastern scotland, eastern side of england, stays largely dry. some sunshine around, we have this band of fairly heavy rain initially for northern ireland pushing into western parts of britain through the afternoon. in the sunny spells, 1a degrees

or so, but if you're stuck under the rain, more like 10 or 11 degrees. still not especially warm for this stage in may. into monday, the main band of rain clears from the east but lingers across scotland. elsewhere, a day of sunshine and heavy showers, could be the odd rumble of thunder mixed in. still relatively cool, around 13 or 1a degrees at best. into the new working week, things start off fairly cool and unsettled and showery, but it looks like we expect at last some slightly drier and slightly warmer weather towards the end of the week. bye for now.

good afternoon. surge testing for coronavirus is being introduced in more parts of england after cases of the indian variant were detected. people living and working in parts of west london are being asked to take a test even if they have no symptoms. most cases of the indian variant are concentrated in the north west of england.

here's our health correspondent, jim reed.
