    IMG 8909

    From the album: La Palma

    An image from a failed time-lapse - this is the constellation Auriga rising through some Canarian Pine trees. The California Nebula in Perseus is visible towards the top and various DSO's are visible in Auriga.

  2. 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.
  3. 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.
  4. 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]

    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!
  6. 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
  7. 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.
  8. 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
  9. 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.
  10. 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.
  11. 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.

  12. 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
  13. 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.
  14. The last weekend I should have not use the telescope, I was sick at home but when I saw this big prominence online I decided to collect my last energy and try. The prominence has few turbulent evolutions and seem to start a detaching movement instead it stay there twisting on itself. This time I presented the timelapse in 4 different color, every personal taste should be pleased. Comments and questions are welcome, and if you enjoyed the movie visit my video channel.

  15. A big quiescent prominence suddenly start to detach from the Sun disc, in few minutes it reach huge dimensions but with lower luminosity, the structure is dissolving with the magnetic lines. I could capture few moments of the event tuning gamma and exposure at each frame to compensate its fast evolution. The transparency was bad, a milky sky, but the seeing was better and let me to take few good frames even if I had to shorten the movies more then usual. I saw the start of this liftoff on sdo website and decide to set as fast as possible the telescope, if i a checked it only half an hour first i could had follow the event since the start, but it is also true that 20 minutes after I would have seen nothing so I don't complain a lot eheh Here you can watch at a high resolution mosaic of the prominence. and few other prominence of that day. The animation represent a close up portion of the Sun of June taken with a 100 ED refractor using a Daystar h-alpha filter at a focal of 2000mm. Hope you like it, comments and questions are welcome and subscribe to my Youtube channel to see many more. YouTube Channel
  16. Here my last video. You can watch at the evolution of a solar image through several stages of processing, from what you usually see in the telescope up to what you find in the final image. The effect of seeing of the first clip is evident and even if there are few moments where you can understand the structure and details, they are ususally blured by turbolence; in the frames stacking you already notice a superior quality, no noise or turbolence, while in the wavelet stage you can finally discover the inner details normally not visible. The last animation is the final work, colored and tuned to show better. I used as subject a close up portion of the Sun of 26 May with the evolution of a huge prominence during an hour of observation. Images taken with a 100 ed refractor using a Daystar h-alpha filter at a focal of 2000mm. Hope you enjoy it and will follow my channel. Follow YouTube Channel
  17. 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.

  18. I just finished to work on the data of 2 weeks ago. The animation represent a close up portion of the Sun of 4 May. Images taken with a 100 ed refractor using a Daystar h-alpha filter at a focal of 2200mm, I reduced the focal do to a terrible seeing. I decided to follow for a couple of hours the NOAA 1734 zone, the bigger one of the week with the hope to catch a big X flares like the yeasterday one. Even if the seeing and the video compression had blured alot of details, the filaments and spicules movements are evident, also a couple of mini flares are visible during the time-lapse. Hope in bigger one next time. The mosaic instead was captured the last weekend at the same focal of 2200, 6 images at different exposure for disc and proms (click on it for the zoom). I also captured a serie of movies to assemble a time-lapse of the prominence, but still on working.
  19. 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
  20. 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
