  1. Many craters have what are called 'central peaks'. Its a process called 'isostatic rebound' during crater formation. YOu ever seen those slow motion videos of a drop of milk falling into a glass, and a drop bounces back up from the surface? Same thing.
  2. I'd just like to say a big thankyou to FLO for the prize, and also for very generously allowing me to swap the prize itself (as I already had a ZWO ADC). Am absolutely loving the new ES eyepiece, its something I should have got years ago. Had some wonderful double star and globular cluster views on Saturday night. Thankyou guys!
  3. Thanks everyone! Honoured and delighted to have won. I might add that Ive got huge numbers of inferior images - the key thing here was being out on the best night in months! A lot of luck in this game!
  4. Hi Chris! Thanks, unfortunately I dont have too many more of that quality - blame the jetstream! I'll have a look though - sadly my processing orgranisation isnt what it could be! Cheers
  5. Yohoho! From a rather good night in April, with my 12" Skywatcher 300p on an EQ8, with an ASI224MC. This image actually made it into a BAA Jupiter article regarding the merger of two white ovals - theyre the ones on the bottom of the north equatorial belt to the lower left of the GRS. Cheers! Nick
  6. Mars in insanely far south so I really wouldnt beat yourself up about that! Thin cloud, in fact, makes no difference to image quality except to reduce the possible frame rate which, with smaller apertures, makes freezing the seeing harder. Ive seen near perfect images taken through considerable cloud. Its more likely to be bad seeing either locally or at altitude thats to blame. Local seeing means thermal issues in the scope and heat rising off neighbours roofs etc. I do like your Jupiter (down the thread) a lot though. Also, not sure why AS!2 cant handle over 18,000 images? If giving it AVI/SER videos Ive given it 50,000 frames before. I dont think there is a limit. Maybe there is when dealing in separate images.
  7. The only time I thought I could markings was using a Wratten 47 filter - this reduces the light levels a whole lot; this should thoretically give the best chance of seeing markings.
  8. Scanning up and down through the thread I think I can see some common features.... be interesting to see them side-by-side.....
  9. Hi Mike! Hows the flu? Lets see those sketches!!!
  10. Delighted to see 2.6 supports the new asi224 which i should receive today.... thanks!
  11. I imagine youve realised that these wil be mirrored relative to yours (possibly excep[ting 9/5) as you use a diagonal...also note that clouds appear different in IR and UV. Not sure which Id expect to be closer to visual!
  12. Hiya these are the images I have on dates you listed. Not my best! Some very quick processes too....bit of a backlog. Also I cant guarantee not mirror image - but pretty confident. Bit suspicious of 9/5, but not much visible then anyway. Cheers Nick 7th April: Wratten 47, 807nm longpass 22/4 UV, and 807nm (worse seeing) 9/5, just one rubbish 807 29/5: 807nm, UV
  13. Thats a good list of observations! As we're both in the UK chances are we took advantage of the same periods of clear skies so good chance there's a date in common. WIll try to remember to look this eve. I think I observed on the 29/5. Cheers
