Hi All,

This was just meant to be a test of the tracking of the G11 with the new Ovision worm in it (see thread in Equipment Discussions for the installation of the worm), but it ended up being a fully fledged LRGB image.

This little one is quite faint.

LRGB 200, 30, 30, 30 minutes.
Luminance in 10 minute subs over two nights.
RGB in five minute subs binned 2x2 on the first night.

Scope used was the GSO 8" RC, camera is the ST-10XME (with all the other add ons), guided using the AOL.

Cheers
Stuart

Nice shot, Stuart:D

It might be faint but you've managed to get quite a bit of detail in the galaxy...you can see knots of HII nebs in the arms. That, and I also like the little galaxies floating about:D:D

That's a nice little galaxy Stu. It seems the new worm will be great for the pickies:thumbsup:

Nice galaxy Stuart. I am really envious of your stars. How are you getting your field so flat? What is the distance that you are working with the reducer or flattener you may or may not be using?

[rat156]

Thanks for the nice comments peoples.

Paul, there is no field flattener in the imaging system yet. I have one from APM which I couldn't use with the original focuser. I now have a Moonlite and may be able to have a crack with it.

I bought the FF mainly for DSLR work, but haven't tried it yet. Too few cloudfree nights.

Cheers

Very very nice. You've picked up a lot of faint fuzzies in the background which is an indication your guiding is rock solid. New worm works a treat indeed. :thumbsup:

[Paul Haese]

Wow that is interesting Stuart. I am trying to get hold of a Tak adapter to screw into the QSI so that I can get the FF at the correct distance. I think this is the real source of the elongated stars in my images. I had it near perfect for the 40D but cannot seem to strike it with the QSI. Perhaps I should just take it out of the system and not both with it at present? Your thoughts?

Sorry for the divergence on your thread.

[rat156]

Hi Paul,

No worries about the divergence. I'll be trying out the FF tonight hopefully...

The field is flat enough without the FF for the size of the ST-10 chip.

Cheers

Lovely little Galaxy Stuart. Ovision, been thinking about one myself but can't bring myself to paying the cost when Losmandy should be rectifying the problem themselves. The worm blocks on the Titan are one piece blocks so the G11 should be the same.

Hope it works well for you.

One of the better images I've seen from the 8" RC, Stuart. You've got the rig really dialled in and under control...or so it would appear! Really nice work.

Stuart,congrats on a fabulous shot!

[rat156]

Well I tried the FF last night. Removed it pretty quickly as it interferes with the guide camera image badly.

Looks like it's for DSLR shots only.

Anyway, as a test of field flatness I used T47 (separate thread), of which I have posted a picture.

I'll also post an individual sub from the first part of the run, which shows camera tilt. I have a Moonlight, but the SBIG nosepiece has cutaways and the Moonlite doesn't grab very well. I spoke with Ron about this and he recommends buying his flat nosepiece. As the A$ is way up there I'll do that.

Cheers
Stuart

That is a cool shot. A couple of other galaxies there too.:thumbsup:
