outstanding image when you think of it

That is fantastic detail since Ganymede is only 1.6 arcseconds across!

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.

I'm sure old Damien Peach has had detail like this before now. 

Brilliant stuff, a bit of competition for Hubble. :D


Must be pushing the limits to get an image like that though.


Not being an imager I really didn't think it possible.

Don't know where this was taken but Mr Peach is usually in the Caribbean or the like with a 14" cass.

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.
