The seeing was average at best, and still a very cold 38 degrees. The data was not good so I attempted my first Winjupos version that turned out decent. I believe the software might have also shrunk the final out put as well.

Still a fine image Mitch, considering your conditions! Well done!

Mitchell, excellent banding detail. Try re-measuring the B channel with the average ref time of R,G to avoid the edge ringing in WinJupos. Then try an RRGB to try to enhance the details. This seems to work for me and my marginal data, knowing that there's not much detail in B anyway. Thanks for posting.

Mitchell I think your image turned out well for average to slightly below average seeing; after 6 imaging attempts on Saturn since Feb 25 I'm convinced that we Northern Hemisphere observers need above average seeing to capture a head turning Saturn image.

A good start Mitchell, especially under the conditions :waytogo: - I'm sure you just need a decent night's seeing to really up the ante.

The "Quadratic size/dimensions" (I think that's the term WinJupos uses - I'm on my little netbook atm and can't check the terminology) which is one of those little boxes on the lower left-hand side of the W/Jupos window where you compile the image etc is adjustable.....and if you noticed some downscaling occurring of the image output it's possible that you had this set to a smaller value.....

The quality of the seeing is everything Mitch, good seeing = good images, all other things being equal. I have always been of the opinion that there are still lessons to be learned by imaging in less than great seeing and don't shy away from it. Reckon you have done well with this image considering the conditions.
