  1. Start of the shadow transit of Io: Start of Io's shadow crossing Jupiter by ejwwest, on Flickr
  2. Some shots of the Moon tonight: Moon by ejwwest, on FlickrMoon - Around Plato by ejwwest, on FlickrMoon around Archimedes by ejwwest, on FlickrMoon - around Ptolemaeus by ejwwest, on Flickr
  3. Taken with Imaging Source DFK21AU618: Jupiter with Shadows of Ganymede and Io by ejwwest, on FlickrProcessed with PIPP, AS2, Registax and PSE 12.
  4. Taken with 800mm lens on Canon 70D and Thousand Oaks filter: Sun with Sunspots by ejwwest, on Flickr
  5. I reprocessed the shot by stacking 3 frames: ISS Closeup by ejwwest, on Flickr
  6. International Space Station Closeup by ejwwest, on Flickr This was taken with a Canon 70D at ISO 2500 and 1/2000s exposure at prime focus of my Celestron EdgeHD 925 scope.
  7. From tonight's pass: International Space Station Closeup by ejwwest, on Flickr
  8. Did some reprocessing of the video with PIPP, AS2, Registax 6 and PSE 12.
  9. Not a great night: cloud kept coming over. For this shot I hadn't properly focused the scope. The later shots when I had achieved a better focus haven't come out well. I'll try reprocessing them tonight. Taken with DFK21AU618, About 3000 frames stacked in Autostakkert, sharpened in Registax 6 and finished in PSE 12. Jupiter and Red Spot by ejwwest, on Flickr
  10. A couple of shots taken with my Imaging Source DFK21AU618 CCD Camera. Stacked with Autostakkert, sharpened in Registax and finished in PSE 12. Not a great night as the mount was unsteady and there was a fair amount of cloud around: Lunar Craters by ejwwest, on FlickrLunar Crater Gassendi by ejwwest, on Flickr
  11. Very difficult to capture tonight due to cloud. Caught between gaps in the clouds and fairly basic focus and exposure settings. ISS Crossing the Moon by ejwwest, on Flickr
  12. Taken with 800mm lens and Canon 70D: Crescent Moon by ejwwest, on Flickr
  13. Looks around mag 11.0 based on the AAVSO chart I printed. Excellent images. I find the colour cast of stacked images in DSS unpredictable at best. Some I've done of M82 come out very blue. But this one http://www.flickr.com/photos/ejwwest/12141997354/ came out more white/yellow.
  14. I created a chart from the AAVSO and I'd estimate the supernova to be about mag 11.0.
  15. Here's a stack of 3 5 minute exposures. There were 11 in all but DSS only stacked 3. May investigate in the morning. M82 and SN 2014J - Guided Exposures by ejwwest, on Flickr
  16. 30 second exposure at ISO 3200 M82 and Supernova 2014J by ejwwest, on FlickrI have about an hours worth of guided shots I'll need to stack and process.
  17. And a shot from today: Sun with Sunspot AR1944 by ejwwest, on Flickr
  18. Took this last night with the 70D at prime focus of the EdgeHD 925. Took 2 shots and merged with PSE 12. Moon past First Quarter by ejwwest, on Flickr
  19. Taken with my Canon 70D at 800mm focal length (400mm plus 2x extender). The retractable screen does make focusing a little better than on the 40D and the 7 shot bracketing useful to get a reasonable set of exposures. Sun with Sunspot AR1944 by ejwwest, on Flickr
  20. Amazing! Rather better than my attempt last night: http://www.flickr.com/photos/ejwwest/11669775226/
  21. I took advantage of the clear skies early last night to try my new Canon 70D out on the Crab Nebula. This is 5x 5mins at ISO 1600 and 4x 5 mins at ISO 3200. 45 mins in total. Stacked with DSS. I tried dark and bias frames in DSS but just got rubbish out, so this is just lights. Final processing in PSE 12 (needed to buy that for the 70D RAW codecs that aren't available in PSE 11, yet the DSS freeware somehow was able to decode!). M001 - Crab Nebula by ejwwest, on Flickr Not up to the standard of others on here, but reasonable first attempt. Clearly many hours of exposures and better understanding of the stacking software is needed to get more impressive results.
  22. Excellent. Looked too low down for me from Chandlers Ford with houses and trees in the way and then dawn light. Managed to get some shots of Lovejoy instead. Am still a novice on techniques for enhancing the images!
  23. Here's a first pass using the DSS Comet function to stack 8 lights.
  24. Taken at the prime focus of my Celestron EdgeHD 925 scope with a Canon 40D: Waning Gibbous Moon by ejwwest, on Flickr
  25. Taken at the prime focus of my Celestron EdgeHD 925 scope. 30 second exposure at ISO 1600. 30 seconds seems to be about the maximum exposure before the movement of the comet against the background starts to show up. Autoguiding against the comet nucleus would be needed for longer exposures I think (which I wasn't set up for this morning). I took about 55 exposures but simple stacking in DSS simply causes the comet to trail on the stacked image. Comet 2013 R1 Lovejoy by ejwwest, on Flickr
