Tweedledee Posted March 18, 2017 Share Posted March 18, 2017 That is fantastic detail since Ganymede is only 1.6 arcseconds across! Bottletopburly 1 Link to comment Share on other sites More sharing options...

Tweedledee Posted March 19, 2017 Share Posted March 19, 2017 Wow that correlates exactly! You can see all the markings are there in the image as per Stellarium, only very slightly more fuzzy. Thing is that I'm sure it is normally difficult to even get Ganymede to show as a disc, never mind image surface detail from this side of the atmosphere with the seeing boiling at a 1 or 2 arcsecond scale. I may be wrong, but I'm sure an imager will put me right on this. Bottletopburly 1 Link to comment Share on other sites More sharing options...
tuckstar Posted March 19, 2017 Share Posted March 19, 2017 I'm sure old Damien Peach has had detail like this before now. Link to comment Share on other sites More sharing options...

Brilliant stuff, a bit of competition for Hubble. Must be pushing the limits to get an image like that though. Not being an imager I really didn't think it possible.

tuckstar Posted March 19, 2017 Share Posted March 19, 2017 Don't know where this was taken but Mr Peach is usually in the Caribbean or the like with a 14" cass. Link to comment Share on other sites More sharing options...

Bottletopburly Posted March 21, 2017 Author Share Posted March 21, 2017 Equipment used for capture - Raymond Collecutt I used my home made 20" f3.8, asi224 camera, 5x powermate, ZWO ADC and it's stacked with AS2 and processed with PixInsight.
