Collected 10x20min the other night with the C11 while still sorting out cables and stuff. This was taken at prime focus but without the AO as I couldn't find any guide star. Still need to learn and some practice on how to focus the bloody guider. Doesn't take much at all to move in and out I guess when I finally find the spot I can leave it there.
So I did a Fred on the processing. There's a bigger version on my gallery here. Thanks for looking.
Hmmm that's an interesting off the beaten track kind of object Marc, I haven't seen very many examples of this on the web, is this the first time you have imaged it?
Ok serious, I would perhaps up the contrast and sharpen it just a tad, but it is a nice starless rendition really, becasue of the FOV it kinda doesn't even look "starless"

Well you know me Mike. Always ready to shoot something new, original, never done before. Seriously M8 is right up, it's bright in Ha, easy to find in a finder and great for testing. Thanks for the comments.

looks good otherwise
I ring Fred and he comes over with his eraser 2.0 Nah just the PS healing brush. CS5 has a content aware tool now. Pretty cool. Glad you like it.

Good piccie Marc
Thanks Carl. You've nailed it. With the PC and the NSW new privacy laws relating to public use of photos you are not allowed to take pictures of other star systems without their written approval.
Good job on star removal! Looks nice. Can t wait until you get your AO and guide combination working. I read your post and followed the link to starlight express. looks like good gear!

Thanks Paul. Yes it's the cheapest way to get flawless guiding with any (cheaper) mount. The G11 is very good but at 3m FL you need PME performance and that's another money bracket so AO is for me.
Cons: Well it's another thing you need to power/connect to and sort out cables and drivers etc.... Also you will have to work a out few things if you want to use coma correctors, field flatteners, filters, etc... that require precise spacing in the image train. I.E. do you put them before or after the AO unit. And there's always the problem of finding a bright guidestar so fast sensitive guider like the SX-Lodestar is the go but it's not included with the AO.
But all together a few intitial setup headaches are worth putting up with compared to splashing $$$$$ on a top of the range mount IMHO. Unless you are of course willing to splash that kind of dow.
You are more than up to the challenge! You will have it singing in no time.. Possibly AO will become mainsrteam soon? I know that there are some exciting products coming to mainstream in the near future. Stuff like gear management units that bolt onto existing mounts and predict and compensate (speed up or down). sort of like AO but mechanical. Also, direct drive mounts (no gears so to speak). I saw a graph the other day for the gear management bolt on unit and the mount was managing a PE peak to Peak of 0.6 unguided!
How are you finding the C11 at F/6.3? Its quite a challenge isn't it? Mine on the EQ6 was unwieldy at best... on the G11 you should definitely have more luck...

That's F/10. No reducer so 2.8m FL. On anymount that's very demanding on the guiding especially 20min subs. In Ha at that FL you won't get much light in so you have to go long. The AO is the only way IMHO. Next to impossible on a G11 with that much weight on. I can't see how. The SVX-AO is a great kit though. Just time consuming to work out like any new gear.
That looks familiar . But different, I like it a lot, the extra FOV has certainly added more interest in this image, youve caught some excellent extra neb there Marc, atmospheric, well done .

Thanks mate. It will be interesting to compare with and without AO. Waiting for another USB to serial adapter as it might be the problem according to the MAXIM DL people. It's working in the SX software though...
