Noice! You're the next dust buster. :thumbsup:

Look how far the dust extends. I don't think I have a chance of getting that with an unmodded camera.

God that's nice!! :thumbsup:

I love that area to image and you have made a great widefield. Are you taking the 8" GSO RC to Astrofest as that would give a nice close up.

I shall be Allan.
I need to work on the focuser before then. There's a bit of slop in it and I think it may be the cause of my eggy stars.

Wow it's amazing what you can pick up. Looking really smooth and natural, well done. I don't think I have seen such a wide field of this before, thanks for posting it.

20-06-2012, 09:47 PM
That's beautifully done. Like a sandy beach. You have picked out the dust delicately. Really like it JJJ.

Very nice, I like that widefield view, shows how big it really is.

Just have to be careful taking long exposures of dusty nebula lest you get dust bunnies on the sensor. :rofl:
I've been wanting to give this region a go and you have given me added incentive.

Go for it. Wide fields, maximum returns for minimum effort. :D

Nice one JJJ, well done. This is one of my favorites objects, will give it a try later on these months :)
