Taken on an RCOS 10" RC Scope at f9, SBIG STXL6303E Camera and PME mount at itelescopes Siding Spring Observatory.
Processed with CCDstack, Star Tools and Photoshop. 98 hrs Total exposure time.

Reason: Its a Cometary globule, not a Reflection Nebula
Oh wow Fred, that’s a hell of an effort, 98hrs? Wow!
Awesome.....!!!!!
It looks so 3D.
So much detail
I’ve had a good crack at this one myself with maybe 12 hrs of Ha but you’re
The king of integration here.
Quick question- why did you frame it like that?
It’s missing the tail end...
Anyway, amazing stuff, the sandworm looks fantastic! - very well done

Reason: Typo
I like it a lot although the histogram looks badly clipped.
98 hours??

Now we know what you've been doing for the last 98 years.
Brilliant and definitive.
Yes, Bart's right about the black end of the histogram. Easy to fix.
Thanks Bart, Mike n Trish, despite the hrs, the background was still noisy and messy, so I clipped it, the hand was better isolated from it.

Thanks Damien. I do have a spot for the scope to do stupid hrs easily, thats my Hubble cheat .

Thanks Bill. There were a few satellite trails, but given enough subs, they are easily dismissed with data reject

BTW why did you stop at 98 hours? Should have gone for the ton.
Thanks Geoff. I did a bit more than the ton actually, quite a few subs were rejected. Its painfull rejecting 1 hr subs, wasted hrs mount up pretty quickly

Thanks Louie. I did try OIII and SII, but nothing there, because its a reflection neb I guess. With Ha as lum, even red showed quite differently to RGB shots. The RGB subs were also 1hr at bin2.

Cheers Marc. Its a bit over red, but green was unattrative on this, it does look like flouro lava

Thanks Andy. I didnt properly frame it, lost the tail and also the galaxy it was trying to grab unforch, which is a real shame. I dont rotate much these days, a bit lazy. Anyway, pointing straight up looked good (and a bit different).
