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

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.

That's beautifully done. Like a sandy beach. You have picked out the dust delicately. Really like it JJJ.

Just have to be careful taking long exposures of dusty nebula lest you get dust bunnies on the sensor.

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