Grog -- The image is 1300 individual frames stacked from a 2 minute video containing about 3100 frames. I shot the video at f/24.5 or about 350x with what is essentially a glorified web cam. Stacking and processing the video frames into a single image has the effect of cancelling out a lot of the atmospheric turbulence, so you'll never get as good a view at the EP as you will with stacking images.
Here's a picture of my setup last night:

Celestron 4" F/10 scopes have been their bench mark scopes for people wanting a rock solid scope for decades.
The OMNI 102 is the best one yet with the XLT coatings, without getting into the ED or Fluorite scopes.

The OMNI-102 is the scope I always recommend to people who want to get started in Astronomy.

I just got an older version of Celestron C102GT...a C102-AZ from year 2000. The deal was too good to pass, so I grabbed it, not necessarily for the OTA only, but for the AZ mount with slo-mo. I know, I know, it is not ideal for astronomy but I need one for terrestrial, and I can modify it with a counter weight for astronomy use as well. Best for both world, I guess.

and they wont part with them, even when they are looking for a larger scopes.
I won't be parting with mine any time soon either. I love that little scope. It's the scope that always seems to surprise me.

there is no fringe visible on the picture. Have you removed it or wasn't it visible?
Independent of the fringe or not a very good image. Well done!
Clear sky,

thank you, yes I have Gimp, too but I still don't know what tweaking is and how it is done in Gimp. Which menu item do you use or is there a description in the internet?
Clear skies,
Roland

Same here, for I've been very impressed with mine and if you've seen my Galaxy Log videos the Omni 102 has been used for many observations of brighter galaxies.
Anyway, though I'm not a planet guy that is a wonderful image Mike
