Wow - now that is a very, very nice image indeed! Good focus and tracking for such a monster focal length. Great processing too!

Cheers

Yes nice shot there. How do you do the guiding with that scope, off axis or guidescope? Also what were the individual exposure lengths?
Thanks for sharing the image :)

I cleaned it up a bit more.
The answer to both the guiding and time questions are:
Unguided and 30 second exposures. My polar alignment was good enough for two minutes unguided but you drop images wheras at 30 seconds I keep virtually every one.

I was imaging at 1600 ISO, one of the steadier nights seeing I have ever had. There was another guy nearby with a 4" Tak and his view of Saturn was...perfect, not good, perfect.
I spend too much time wandering around chatting to others to do really good imaging, not enough concentration. For example, on this night I wasted 30 minutes setting the DSLRFocus software wrong and taking a single 30 minute exposure, Canons do have a heat problem that pops up...eventually...
Later that evening I took 30 1 second images, jeez!
The only thig that was worse was that because of my chatting I didn't go back and see that mistake for another 30 minutes!
Most of my imaging is follwed by the epitaph " jeez, if only I had a little more data"
The image attached is a recent image of my scope with me (in stupid green frezer suit) and an American Amateur visiting Perth.
