  1. 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:
  2. 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
  3. Hello, This is my first Milky Way timelapse Canon eos 1200d with kit lens 18-55mm. Made 212 shots at 25s exporsure iso 3200.
  4. 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.
  5. Seeing was mostly poor, but I am quite happy with how it came out
  6. While I was exploring the Sun disc looking for a good subject I found this small active zone next the limb, that was erupting, I decided to follow its fast closure with short captures, infact after only 10 minutes the event was ended. To build the movie then I added a second surge prominence I captured few months ago. As you can see also from the Earth scale, the sujects this time are very small events, like micro surge, spicules eruption, all watchable only on the edge of the disc with very fast capture and lower exposure respect to the filming of normal prominence. Usually they are burn and overexposed losing any details. You can also see plasma falling from the other side of the Sun. YouTube compression blur many of the details but I hope you will like it.

  7. 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.
  8. finally sorted out the videos on my desktop machine so I could get the colour balance right Starry skies - 1000 x 5 second exposures over 90 minutes and 2480 raw exposures make up this Cloud timelapse over 8 hours as always best viewed on Youtube in full screen

  10. A short timelapse of the Aurora the mob had on the Isle of Skye before getting into viewing the heavens with the dobs. Skye Aurora Timelapse Sorry there's no sound media isn't my speciality
  11. 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..

  12. 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.
  13. 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]
  14. 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.

  15. 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.

  18. Hi Folks, I decided to a have a few bashes at time lapse before heading to the Isle of Sky in May where i'm going to have very dark skys but hopefully not due to cloud. Sorry for the external link but i never manage to up load anything staright to my postings, maybe someone could explain. This was taken with on: Canon 550D Astronomik cls clip Sigma 30mm 1.4 Total of 236 x 13s with 8s intervals Time lapse video on Flickr
  19. As many others, I was out taking pictures of the Lunar Eclipse this Friday. Though the moon didn't rise until half way through the eclipse, and clouds coming in just as it rose above the horizon, it cleared out and I gave it a go! I hadn't planned doing an actual time-lapse, hence why the exposure length and color balance is all over the place. Not until I sat down and had a look at the pictures at least. Some of them I tried to fix with Photoshop, but it was honestly a very big task at hand, so I only did minor adjustments, and then just added the some stills at the end of it. But have a look if you like! As always simply observing the eclipse was also a treat, and this was only my second time watching one! Thanks for watching. Next time I will definitely try to actually properly prepare for a timelapse, instead of just smashing whatever pictures I captured together
  20. 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.
  21. 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
  22. 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.
  23. I just try to show the beauty of the night sky, and again the possibilities with a smartphone. There are already better applications at the google play to make the night lapse easy. At first I used the Gif maker pro. It's a good app to edit the frames, before creating video, but you can't save the videos in good quality. Now I use the TimeLab app (same developer, as Intervalometer app), in the editing it has not so many options, but with this app you can save the videos in 4K too, or full HD. This video is 360 frames (each 30 sec exposition at ISO 800) Huawei P10 monochrome camera, Intervalometer app, TimeLab app. Pictures taken in Kleinwalsertal, Austria 2019. 09. 23-24. (The video is full HD, I don't know, why, but it doesn't run continuesly on my PC, when I watch that back on SGL. I hope, on your monitors you can enjoy it!)
