Thanks for commnets/tips.

Hello again,

this is the first attempt at approx. f/30 (difficult to judge with the modular Zeiss barlow). The seeing did not cooperate this time and I believe this is the best avi from that night at that focal length. I still have another one, but it doesn't look any better than this one, from a first look.

However, I was experimenting and I can't recall the UTC for this image.
Data are the same as the previous picture with the exception of the focal ratio (f/30) and the no. of frames acquired and stacked (1000/1800).

It seems that processing brought out some artifacts, so I have a difficult time assessing what is detail and what is processing problems. I believe that there's more artifacts than actual detail.

However, I would appreciate comments and advice on this one.

Ciao
Luca

Hi Luca,

If I remember correctly you have just started doing planetary imaging and I have got to say you are doing much! better than when I first started about five years ago.
This is a good image (UTC 20:59 image), the edge definition around the perimeter of the planet is excellent and Io (I have not checked so I assume it's Io) shows up as a nice disk, as I am sure you already know seeing is at least 90% of getting a good image.
With out a detailed list of your processing steps I don't have any good tips for you (I don't use Iris so I might not be able to help there) but I can say you are doing great and keep after it

Thanks,

Wes Higgins

I promise this is the last one for today

I have corrected the UTC on a previous post of mine and I post now the real 22:21 UTC image. I kind of like this one better than the previous one from this lot as processing came out much smoother, thanks (again) to Paolo's precious hints.

Thnaks and ciao to all.

Thank you all for the kind comments and the useful tips guys: I couldn't have got this far if it weren't for your help!

Thanks
