  1. Having taken some images last week when we had a good spell of seeing I had pretty much filled up my hard drive with files and I've since been clearing and sorting what I have. The attached are a few mars animations showing the planets rotation over an hour or so on the 16th and the 21st to 22nd of September as well as the best still I have so far processed. I'm still not happy with my processing but hopefully that's a skill that improves over time. All taken on 8.5 inch newt with asi224mc. The first two at around f18 and the last and the still at f33 with a combination of barlows and bits (basically imagine if Frankenstein made an image set up) All processed through pipp and as3. Still was taken from 35% of 15000 then registax for wavelets. Right then, back to my digital housekeeping, only another Tb to sort!
  2. I went this weekend to my girlfriend's parents and I took my Skywatcher 72ED with me and the smaller AZ-EQ5. Fortunately, the skies are dark there. So, on 11/12 August I put all the stuff on the mount and took 130+ 60s subs with the Canon 550D. The result is a crop, towards the edges the stars are not perfect yet, but they're a bit better than in the past. I put some additional spacers to the universal flattener and increased the backfocus distance. The comet doesn't fill the frame anyway. Unfortunately, the animation doesn't really play ball, I will upload it somehow else later. Neither on the processed image I did the best job, I need to improve somehow in removing the artifacts on the comet-only image. However, this is what I got:
  3. I pointed my solar telescope at a small prominence in the hope that it would do something whilst I imaged it. Because I am new to solar imaging I don't know whether this is particularly lucky, or if it's something that's easily caught. Over the space of about an hour I captured 18 videos, each of 1000 frames, using a mono DMK21. I stacked 10% of the frames, and then manually went about aligning and cropping the 18 stacked images because ImPPG didn't like to do it for me. I also took an image of the solar surface, just to get rid of the white in the image, and add something visually interesting to the solar disc. I used a curves adjustment to make it orange, and then made a movie in MS Movie Maker. Hope you enjoy it! solar_prominences_long.mp4
  4. Hi all, Some days ago I released a new project at animating the cloudbelts of Jupiter and the GRS. In order to have an almost continuous monitoring of Jupiter, we contacted 91 amateurs from all around the world to ask for permission to use their images in this project. It took a full year and thousands of hours of work to get all the pieces in place but I'm quite pleased with the results. John Rogers, Director of the Jupiter section at the British Astronomical Association has written: "An amazing animated map of Jupiter's winds has been released by Peter Rosen and colleagues in Sweden, portraying real observations from images by amateur astronomers over 3 months in 2014-2015. The map (in various projections and perspectives) shows Jupiter's winds in glorious detail, and this is by far the best such movie ever produced from ground-based images -- worthy to compare with the Cassini movie." I hope you enjoy it It is now up and running at https://youtu.be/YZc1Y662jtk /*Peter Rosén
  5. A lovely morning here in St Neots, Cambridgeshire: a light breeze only, thin cloud keeping away from the sun, equipment working perfectly. The only problem is the seeing. It's not the usual "wobbly" sort, rather it seems to make everything slightly blurred. Ah, well, can't complain... This is my longest animation so far; 1 hour 20 minutes in 85 frames. I hadn't bargained on the image getting brighter as the sun rose higher, so this one start dark and gets brighter over the 85 frames. I was lucky to catch it at a particularly active time I think. Gotta love that H-A action! The last animation was slightly jerky so this time I reduced recording time from a minute to 45 seconds and tried to record data back to back with no gaps, which was not always possible, as the unguided scope needs regular correction. Still, it's come out much smoother than previously. Iain

  7. Hi, using my wacky NexStar SLT and Celestron Mak127 is often frustrating, but when hunting planets it can be rewarding to overcome the limitations. The images are done with a ASI120MC and Firecapture. Used a 3x Barlow. Processed in AS!2, sharpened in Registax, touchups/GIF in GIMP 2.9.x. Cheers, Carsten
