You will find the C8 very difficult. Its better if you can eventually get in some focal reduction (and no barlows), we can talk about that later. It will also be slow going without a goto mount.

Yes I have a 1.25" nose piece.
I've been studying photography in parallel to get my head around the relationship between FoV as it relates to aperture, focal length, and CCD size. Not difficult to understand, just a challenge for me to put it all together. You'd think an electrical engineer who specialises in RF would not have a problem...
go figure!
The mount was tracking, just poorly, I have yet to successfully polar align so I always have some drift in declination, some nights worse than others. I didn't have the HEQ5 when I first used the camera.

I started out just trying out the camera to see what I was up against. I tried using the stacking feature in SharpCap but it complained and I gave up. Then I found the tutorial that Mike Salway put together to process a single image from a video and I tried to follow that and had alignment issues. I'll check out the YouTube link, thanks!

If there's ever an observing night up the coast I could come up (I'm near Hornsby so not that far away). I'll bring my gear, and you can try my camera/reducers etc.

I was able to get some reasonably exposed videos of Saturn, but seeing was pretty mediocre, add in the tracking error and you get a bit of a mess. But I can show them off when people come over for BBQ's
. It would be great to meet you, I'm slowly expanding my circle in the forum whenever possible. If you follow the NSW informal Astro Camping trips
http://www.iceinspace.com.au/forum/s...d.php?t=141805 and the NSW Central Coast Casual Observing
http://www.iceinspace.com.au/forum/s...d.php?t=141802 threads, you'll likely find me.
again for all the advice and links.
