Another M16 (7-13-10)

This M16 is 27x4' with the SXVF-H9C through the AT8RC at its native f/8. I still have funny star shapes, just a little. I think I have narrowed it down to slight miscollimation. No need to throw out the data, though. What a fascinating object! No filters on this one, either.

I'd be interested to know which of the two versions is preferred. The first image above is truer to actual colors, I believe. The second maximizes the Ha glow.

Outstanding, mate! Very nice work.

You've obviously been getting better weather than us here in Austin. It's been months since I've been able to get out. I even went down to Australia in June and was hemmed in by clouds there, too. Not my year so far!

Cheers,
Phil

Thanks, Phil. Well, we had two clear nights in July, and I caught one of them. The other was hazy but I set up, anyway. Other than that, it's been cloudy or hazy since May 5. I am in Utah right now, and the first two nights here were clear and transparent. (The full moon apparently burned off all the water vapor.) I'm hoping it clears off again next week. I brought a camera.

Thanks, Bill! Yes, as long as the sky is clear! I just picked up an MPCC for the 6", so you'll see some new images from that scope soon, too (well, after I get back---it was too big for this trip)!
