Got some more data Sunday night and this time my guiding was a lot better (for a little while anyway) after a few tweaks on the worms and the mount.

I did 63x3min but kept only the best subs. Image scale is 0.63" per pixel.
90mm refractor + FFC x3 so 1800mm FL. Next I'll try with an AO which should make life a lot simpler.

I've got some pretty cool details this time and some really faint stars so I put a 1:1 field here (http://www.astropic.net/astro/keyhole_fff.jpg).
And there's a 50% high res here (http://www.astropic.net/astro/keyhole_f.jpg)too, bit easier to download.

Enjoy the view. :thumbsup:

Thanks Alistair. :thumbsup: The FFC is the Baader Fluorite Flatfield Converter (http://www.astro-physics.com/?products/accessories/baader/ffc). It's a very good barlow. AO is adaptive optics yeah. I should really try to use the one I have at that FL to improve star size. My guiding is a lot jumpier right now. Problem is weight and balancing. Might try with my newt next which is a bit more sturdy.


Thanks Larry. :thumbsup:

Thanks a lot JJJ. :thumbsup:

That's a very nice image Marc; heaps of detail for just a 90mm scope! :thumbsup:

Thanks David. :thumbsup: I'm working on my guiding now to get tighter stars. I reckon I can get much better results with a bit of tweaking and some tilt too which I suspect are the paddle pop sticks I use to space the camera. :scared3: . I got a little excited when the weather cleared and rushed a little into things to make it work.

Thanks mate. :thumbsup: Looks like we might get some clear this week but the seeing's gone. Time to get those lenses out again.
