  1. Finally a clear night and some good images grabbed with my DIY All Sky Camera. All stitched together in Light Room and the resulting video stuck up on YouTube and now linked to here Hopefully it will be clear again soon and can get some more good timelapses. Shame I am not further north with a possibility of an aurora, but hey ho. Thanks for looking
  2. hi Recorded this over evening of 18th Jan to 19th Jan 2018, circa 2889 frames each of 12 second exposure, merged into video lasting about 3m 12secs. Big meteor at 1m17secs Recorded using Starlight Xpress Oculus all Sky Camera 180deg lens and AllSkeye Software. Note this is the video of the whole night, related to previous submission of just 1 frame of big meteor, although wasn't sure if should put in same or new post. thanks Jamie 19th .mp4 Edit: for those that dont want to download whole file, same one have uploaded to youtube if easier although lower quality:
  3. Hey all. My interest in timelapse has been building over the last couple of years. After an attempt to do some at SLG 11, this has been something that has been bubbling on the back burner for a long time. My interest has once again risen in getting this going as I now have what I think will be a fairly nice setup for doing Day to night (Holy Grail) time lapses. Here's the kit that I'll be using..... 1. Canon 70D 2. Sigma 17-50mm Zoom lens at F2.8 (Over the whole range) 3. 2 axis camera slider 4. iPhone/iPad - running qDslrDashBoard 5. Lens muff - and single use hand warmers This setup fits together rather nicely. The slider that I have does Move-Shoot-Move, after moving it will trigger the camera via the shutter release cable. (I could use an intervalometer for this, the slider has the feature built in so no need to complicate things even more.) The Canon 70D will be mounted on the slider on a ball mount. It connected to the iPhone/iPad over WIFI (I thought that was a gimick at first). the iOS device will be running qDslrDashboard which will perform the settings tweaking for the Holy grail stuff. The Sigma Lens at F2.8 will be faster than my kit lens (F4.5) The Lens muff, will be wrapped around the sigma lens and have 3 single use hand warmers (lasts 10 hours) to keep dew away from the glass. All in all, I'm getting rather excited to trying this out
  4. Time lapse video of Asteroid Florence (3122) taken 1st/2nd September 2017 between 22:09 hours and 00:24 hours UTC. 10 sec subs at 20 sec intervals rendered at 20 fps.
  5. Seeing was mostly poor, but I am quite happy with how it came out
  6. I've had a few clear nights recently and had to miss them all so have been able to turn to some earlier data. I've put together a series of timelapses from my annual weekly holiday with my in-laws in Cornwall every April at Gillan Creek near the Helford River on the Lizard in Cornwall. The very first time-lapse starts off with a 3/4 moon behind the camera and the Milky Way rising, as the Moon drops then sets the ground gets darker and the Milky Way more obvious. Two of the time-lapses were done in daytime showing the tide coming up on Gillan Cove. The people visible in both of these are mostly family The area has many scenic spots I would love to time-lapse from but as you'll all know too well getting the tides, the Moon and the weather all right at the same time is quite rare! The time-lapse was exported at 4K resolution - if you have a good fast internet connection then that will be best, otherwise 1080p (HD) works well. -- Equipment used: Canon 6D, 14mm Samyang lens and 24-105mm Sigma Lens Motion is provided by a Vixen Polarie with time-lapse adaptor and/or a Digislider motorised slider The background track is "Billions and Billions: from A Moment of Stillness" by Stellardrone (stellardrone.bandcamp.com) Hope you enjoy.. James
  7. I've been going to star parties for about 10 years now and more recently have taken up time lapsing - partly to get around the lack of clear skies (time lapsing isn't as dependent on completely clear skies as regular astro-imaging is) and partly as it means less kit to cart around... although I now seem to have accumulated too much again. Attached is a time-lapse I've put together of several timelapses taken at Kielder Star Camp last year, spring and autumn, and this years spring event we've just had. Star parties are about the stars/astronomy of course, but are also social events (it's usually cloudy after all) and it' always great to catch up with old friends and make new ones. But... if the skies are clear get things get very busy! The most recent star camp was warm and sunny over the Saturday and Sunday (rather rare!). When it's looking pretty likely it will be clear everyone is out making sure their setups are working, batteries are charged and so on and there's usually a general sense of anticipation that builds as it gets dark. These timelapses show the red lights used by astronomers (red light doesn't ruin your night vision) and if you are sensitive to flickering lights maybe don't watch the time-lapse :) I hope you enjoy this... it's been enjoyable (albeit cold!) capturing the timelapses although processing them afterwards can be a time consuming pain ;) If you've got a fast internet connection its best to watch the time-lapse in at least HD (1080p) - 4K is better. Detaily stuff... Most taken with a Canon 6D, 25 second exposures at ISO3200 using a Samyang 14mm lens. Orion picture taken with an astro-modded Canon 650D. Processed in Lightroom with LRTimelapse. James PS Looking forward to the SGL star party in the autumn
  8. It occured to me that I should share with you the timelapes of this year's Mercury transit as seen from Czech Republic. The clouds have parted for some 20 minuts, allowing me to capture this timelapse. I shot it with a modified webcam, Baader 2.25x Barlow and UV/IR cut filter, using my former SW MAK 102/1300.
  9. Hi everyone. I recently acquired a ZWO ASI120MC-S and so with the bright summer skies I've turned towards solar and planetary lately. I'm not great at either, but I'm learning This is the result of my efforts from last night and I'm quite pleased with how it turned out given it was ~3-4 hours of sitting in the relative cold of my front garden. I've never managed to time weather & my availability with the GRS or a Jovian moon transit before so that's two firsts for me. The seeing was "soupy" to put it lightly, especially towards the end when the planet got lower in the sky and ended up over the roof of a house across the road, but I can't complain - at least it was clear! I took a video around every 5 minutes for almost 2 hours, stacked the best frames, then compiled into an animation of 19 frames that loops back & forth. Io started off about 1/3 of the way across the face of the planet when I started recording data so it's a bit tough to see but you can follow it back across once it pops out the other side. Thanks for looking! I hope the attachment works correctly because I couldn't seem to get the gif size down below ~14mb, so I apologise to anyone on a slow connection!

  10. Lunar Eclipse timelapse (final)

    3 cameras, 6 hours of shooting, 2000 images and a heap of post processing best viewed on Youtube full screen HD
  11. Hello, This is my first Milky Way timelapse Canon eos 1200d with kit lens 18-55mm. Made 212 shots at 25s exporsure iso 3200.
  12. I was lucky enough to spend two weeks on La Palma in the Canary Islands this August with my family. Whilst we were unlucky with the weather in the first week (it rained, was cloudy and the air was very dusty blowing across from the Sahara) the second week was much better with some stunning skies and views to be seen. My original plans for various time-lapses was thrown out of sync (not entirely unusual for any UK based astronomer) and I ended up with just 4-5 nights to capture what really needed about 8-9. Whilst there's a lot I couldn't do, I was able to get a fair amount including two nights up in the vicinity of the Observatories on the Roque de Los Muchachos. Some of La Palma's most striking views involve clouds - the Caldera de Taburiente (a stunning sight from wherever you look) regularly fills up with clouds looking like a bubbling cauldron and sometimes clouds cascade over the Cumbre Nueva - a mountain ridge across the middle of the island. This ridge often holds back those clouds - it's not unusual to drive from the sunny west side through a tunnel onto the east side where it's cloudy, raining and much cooler. I was able to capture a quick time-lapse of clouds cascading over the Cumber Nueva from the Mirador El Time whilst enjoying a coffee at the cafe there. It doesn't get much better than that!! The earlier time-lapses were captured in the vicinity of the villa we stayed in, El Sitio in Fagundo, Puntagorda. Some of the later ones were captured at the 'Hacienda La Palma' from about 4500ft (1370m) altitude and some from in or around the Roque de Los Muchachos. The skies at Hacienda La Palma and up at the Roque were stunning with virtually no light pollution. Even lower areas had skies far better than usually seen in the UK. Phenomenon such as the Zodiacal light (where dust particles along the plane of the ecliptic are illuminated) were very obvious and whereas in the UK the predominant colour I have to process out of images taken is orange from light pollution, in La Palma the skies' natural green glow was very obvious in my images. That said, La Palma is a cloudy island - most of the clear nights in my second week there were due to my being at higher altitude. It was a common sight to see overcast skies hundred of metres below but not a cloud above. This video is a compilation of some of the time-lapses I did get. I made plenty of mistakes on these time-lapses, not least I should perhaps have gone when there was more moonlight to light up the ground a bit, a little different from the approach to astroimaging we're more used to.. all the more reason to go back and try them again of course Hope you enjoy.. don't forget to make sure the HD button is on when watching and turn the sound up, or down depending on preference Kate and the kids are visible in a couple of spots, I deliberately left them in - but I removed the selfie taken at the top of the Roque de Los Muchachos just after sunrise one morning as I looked about 90!!! Four sleepless nights hadn't done me any favours! Equipment: I used a Canon 6D, modded Canon 650D, 24-105mm Sigma lens, 14mm f/2.8 Samyang Lens and a 8mm Samyang Fisheye. Tracking and panning were done using a Vixen Polarie with a time-lapse adaptor. https://vimeo.com/139641078

  14. Taking advantage of the short break I managed to finish the processing and post processing of the data collected and to assemble this short clip. I followeed for an hour the first moments of detaching of an arc prominence; evident the plasma falling back on the sun while the upper portions began to leave in the spce. I also added a timer accelerated to highlight the time elapsed, as suggested to me by someone. Unfortunately a bit 'of detail is lost in the compression site but I hope you will like it . Here also few images of that day.
  15. GIFV version - http://i.imgur.com/71aFPTQ.gifv My first try at time-lapsing. The Moon & Aldebaran Comparison between Aldebaran and The Sun Connected my iPhone to a 25mm eyepiece (Skywatcher 10") with a DIY adapter.Took a picture about every 30 seconds for something like 20 minutes (probably 18).Aligned each frame in Photoshop (since I couldn't figure out how to let PiPP align it on the star), and cropped a bit.It was taken under a very thin layer of fine clouds, although there's one frame in there where the clouds decided to get thick.
  16. After sleepless nights (almost 800 files to sift) here is the video on the last solar eclipse. I assembled few timelapse made during the event (for a couple I had to give up because they are too rowdy or because the computer was not able to save all the files); I was forced to use clips of only 5 seconds without intervals due to the high speed of the moon at this focal, but I managed to achieve a fairly uniform level of detail ( a post processing challenge ). Given the number of movies I had to give up treatment too complex or it would take me too much. I suggest the vision of the video at full resolution and full screen to appreciate the slow movement of the sea of spicules and plasma. With frames so close together transformations are minimal but very fluid. And here few single captures, were I could give more attention to the moon edge and color presentation, hope you will like them. [url=https://flic.kr/p/qM5rAd] [url=https://flic.kr/p/rK3Vq7]
  17. Orion timelapse

    From the album Jon's images

    Quick Orion timelapse, Saturday the 14th of March, back garden in Southsea. Stock Canon 70D + Astronomik CLS clip filter, 14mm Samyang lens, f2.8, iso 3200, 22s each shot. MP4 doesn't play well on here so it was converted to a gif...not great either!
  18. Eheh, ok I was joking, the video is mine. The last weekend was terrible, rain, wind storm, cold. I spent it at the desk playing with past captures to produce a short clip of presentation of my works. Here it is, lady and gentlemen!! Enjoy. Video HD
  19. After few days of rain and storms the weekend of 4th was clear with only few small clouds passing through. The seeing was average and with a Sun with so many prominence (my favorite subject) i couldn't resist and spent several hours of saturday and sunday imaging. I just finished to work at the data, in the clip you will find the best prominence captures and a timelapse of the huge one, which keep us entertained for two long days. I suggest to see the HD version to better enjoy the spicules details. Hope you like it, all captured at 3 - 3.5 meter. Video HD The presence of few promninence next the bigger one suggested to make a big mosaic (3500px) of the big system. Full resolution Here few of the images, you can find all of them also in colored version on Flickr Full resolution An huge tornado Full resolution Full resolution In the afternoon I also run at the neighbour town to capture a fast ISS transit.
  20. 700 x 6 second exposures. Captured during the timelapse were a tumbling satellite and an aircraft contrail casting a shadow onto the clouds Best viewed on Youtube in HD
  21. The sky was not entirely clear and I hoped for a good seeing with the absence of winds, and in fact in the first half hour watching at the eyepiece was significantly better than the last attempts of this year 2014, but still far from the standard to which I was accustomed a year ago. I then made ​​some capture at lower focal on prominences and main formations and then decided to capture the evolution of the one that seems most interesting, a beautiful tree shape quiescent prominence, it was persistent for several hours, but get involved by a magnetic twister born from the next active region. During the shooting the left side of the prominence was teared off by a magnetic vortex which disturbs the structure turning it around horizontally, while the right side, out of the reach of turbulent magnetic field, it remains inactive and almost untouched. Unfortunately the seeing was quite terrible as soon I started to image but I was interested in the prominence evolution so I continued filming it; even if the details are blured the movements of the plasma is clear and understandable. Images taken with a custom 150 truss refractor using a Daystar h-alpha filter at a focal of 2500mm, the video show 1 hour of real time. Video Waiting for better times I hope you like it, I attach also some shots made ​​in the beginning when the details were at least partially visible.
  22. Project Widefield

    Although I'm more interested in visual astronomy, I still think it's fun to try some basic astrophotography every now and then. However, I don't think I have the time or patience to get into "proper" prime focus DSO stuff (ordered Making Every Photon Count out of curiosity anyway, you never know, right!?). At least for the time being. But I do want to get started with some widefield work this year, both still images and time lapse videos. I'm currently investigating the various options when it comes to tracking platforms such as iOptron SkyTracker/Skyguider, AstroTrac, Vixen Polarie and so on. Still not sure which way to go with that just yet. Anyway, I've started to put together some other various bits and pieces to get going. Just recently got an adapter to mount an RDF on the camera using the hotshoe to better be able to aim it where I need and want: http://www.teleskop-express.de/shop/product_info.php/info/p5641_Lacerta-adapter-for-mounting-red-dot-finders-to-camera-flash-shoes.html Also have an intervalometer that I bought last year, but havn't used much so far: http://www.teleskop-express.de/shop/product_info.php/info/p1464_Programmable-SLR-Remote-Control-for-Sony--Minolta.html I will, when the weather improves, try some basic shots with the camera on a fixed tripod (Manfrotto 190 PROB) just for fun. I've see some very interesting results here on SGL lately.
  23. After months of delay due to a very bad weather and work issues, I was able to use my new open telescope to image the Sun. In reality the conditions were not good , I think seeing about 2 , but the combination of clear skies , holidays and a solar show was an opportunity too good . I then prepared the refractor and pointed our beloved star to capture a giant prominence that I spotted online. Mindful of the first test I mounted the extensions to get the minimum focal lenght (2.5m) , the turbulence was evident. I captured and followed that titan for quite time in different positions waiting for the moment that seeig seemed more quiet, then I found realize that on the right a little active zone appeared erupting plasma; there were the classical loops after particularly energetic flares. I decided so , at the expense of poor seeing , to devote myself to a short timelapse with the Sun even lower in the sky; you can see the result from adverse conditions but it remains a memory of this event particularly rare for me. Before close the session I also tried the loop at full focal (5m) just for fun. Although not perfect , I'm glad to see the first results with the new refractor , I hope to have more sunny weekend in the near future , unfortunately the remaining holidays was cloudy and I am given to processing.

  24. After the break to the mountain which I have dedicated to elaborate a bit of the material filed in time, I can finally go back to photograph. 22th morning, the sky would be especially transparent and clean, thanks to the storm of the night and although the meteo told about terrible seeing I wanted to try anyway due to the presence of some beautiful formations on the Sun. To my surprise the turbulence was almost absent at the begining, and I could capture sequence of images tho assemble the mosaics, but these are enough to exhaust the lucky seeing, and when I was setting the camera for the timelapse I already saw the first signs of deterioration which are then fulfilled during the shooting sequence. I tried to continue anyway stopping after just over an hour, even after a couple of hours I didn't see any improvements so I decided to dismantle everything and see what I could pull out of the collected material. In fact, this time, since next to one of the brightest prominences were visible a few spots and filaments, I wanted to try a totally different settings that allowed me to capture both the prominence that the details on the disk, which is always tricky with narrow filters. If it will happen again I'll have to keep exposure times longer to have more data on the weak details; in post processing then I had to study a totally different approach and I have had to duplicate each frame in order to be treated differently the disk and prominence starting from the same shoot. A faster method would be to work on shadows and light but noticing a loss of some points on the histogram I have taken the long way and hardworking. Since then the highly variable seeing I had to change the stacking and the final processing to try to normalize the level of detail as much as possible, I must admit that it was a work particularly long, because I has precluded the use of certain macros that usually use. Although at the end of the capture there weren't any cataclysmic events the level of detail at full resolution is good and if you focus on portions of the video and not only to the overview, you can see micro movements and evolutions. In particular I'm curious about the migration of certain points of greatest intensity next the main spot group NOAA 1820 more visible in the negative version, I usually think about Ellerman bombs but this ones were moving from the umbra and follow the filament/spicules and makes me wonder if by chance it is not a case of those phenomena recently discovered by UCLan university and still under study, in which they occur condensations of energy along the magnetic field of the spicule / filaments which radiate from sunspots by traveling in their length. Unfortunately the compression of Youtube has mixed some of the details but I hope you will enjoy it anyway. Youtube Channel
  25. The day after I received my new camera the Sun gave the show with this huge prominence, and although I eventually had several driver issues, I managed to follow its evolution for half an hour before the sky completely veiled. I hope you will enjoy. At the end uninstalling the 13.1.7 drivers and installing the 13.1.6 High Performance Driver seems to have solved the high instability of the camera, which freezed each time. There remains the problem of newton interference bands. I forgot, here you can instead see the mosaics that I made before the timelapse, during the tests. http://www.flickr.co...lvy/9332248461/ http://www.flickr.co...lvy/9332248765/ http://www.flickr.co...lvy/9335037034/ PS - last week I forgot to post the video of the most spectacular events, here it is.
