It certainly beats my "big dot for Saturn", "Little dot for Titan" images! Nice!

That "dot" is Dionie not Titan, according to the "Gas Giants" app.

Sorry, I was referring to my own image where the small dot is Titan. I did not make that very clear, did I?

HAHA... they're all dots and pixels from our distance... have you uploaded anywhere? I'd like to see your work.

I've posted rather fewer images in here than I thought and, honestly, most are not really great, certainly not a patch on yours. Here are the links to the ones I can find:

Superb imaging MarsG76.

I see you've said your imaging at f33 with a C8 - how are you getting to f33: extender, barlow, EP projection...

Although I've been imaging DSO's for some time I've only just dipped my toe into planetary (this week).

Currently using a TS RC8 and ASI662 so my image scale is much smaller. Waiting for a 3x tele extender to arrive.

I came to the figure of f33 by using a formula I found on Cloudy Nights which allowed me to calculate the focal length by the distance between my CCD and the Celestron 2X Ultima Barlow.

The setup was C8->2X Barlow->Vixen Flip mirror (15cm)-> CCD.
BUT recently when playing with other features of WinJupos.. such as the focal length calculator, WinJupos calculates this image as f52!?
