  1. Crescent Moon DSLR on ED80 at f/15 Peter
  2. Now less than 0.5 degree apart. A couple of images from a DSLR on an ED80 at f/7.5 and f/15 Peter
  3. Keith, If you mean the strange left edge curved features, this is edge rind, a well known phenomena. It's caused by diffraction patterns from the optics. It's a real pain and hard to avoid. Google it. Peter
  4. Managed to get about 10 mins on Mars between the clouds. Only 12.9" diameter now. Some nice high altitude clouds on the terminator side. Elysium is very bright at lower left. Mare Cimmerium and Sinus Gomer prominent at centre. Peter
  5. Getting closer now in ED80 field of view - DSLR 1/100sec at ISO 400 Peter
  6. Hi Craig, I have read somewhere that the edge rind stays the same size, so therefore looks worse on smaller disks. Peter
  7. A quicky Mars image in jittery seeing from between the clouds. It's getting much smaller now at only 13 arc secs diameter. Syrtis Major on show. Peter
  8. Looks like the dust storm is pretty much over now. Even in the Hellas Basin, there are normal details appearing again. SInus Sabaeus and Sinus Meridiani central in image. Horrible edge rind on bright limb again. Peter
  9. Thanks Darryl, yes not many new images or comments. Peter
  10. Very impressive images. Well done Peter
  11. Quick shot with DSLR on C14 with 8" dia white light solar filter
  12. You are correct, the 'edge rind' is a diffraction pattern and even the best imagers get it. It is affected by seeing but don't worry, it's not anything you have done wrong. A lot of people use the smudge/blur tool in PS to reduce the effect. Peter
  13. An image from last night. The dust storm seems to have died down a lot, maybe some dust near Argyre region at 10-11 o'clock on the bright limb. Certainly Solis Lacus and Valles Marineris look back to normal. Mars looks much smaller now at 15.7" compared to 22.4" at opposition. Peter
  14. Here is my first attempt at a full 360 degree map of Mars from images taken this year. We have not had that many clear nights from the UK, so don't have that many images to choose from. I think it would be better with more images covering the 360 degs rather than having to use wider segments from each image. Not sure how to get better transition between segments. Any Winjupos experts out there have any ideas? Peter
  15. Despite strong gusts of wind and jetstream overhead, the attached image clearly shows the spreading dust storm on Mars. The dust is spilling over from the Solis Lacus region on the bright limb at 10 o'clock. I look forward to watching this storm develop and the active region rotates into view. Peter
  16. Lovely image, a nice natural feel to it. Peter
  17. Great set of images. Those light marks are the start of a dust storm that is now spilling over half the planet. Well captured. Peter
  18. I have done a more sympathetic processing, less aggressive and I think it is a more pleasing result. I also used the auto colour balance in Registax to better effect rather than using levels in PS. The first image is the original one posted with the newer one below. Peter
  19. Hi Pete, thanks. I tend to do 10,000 image runs which is about 1.5 mins. So this is 6-7 runs de-rotated together. Peter
  20. Some great detail. Could boost colour saturation a bit I think. peter
