The Eagle nebula (click here for big). Part of M16 in colour mapped Narrow Band. Most of the stars have been deleted.
Taken on an RCOS 10" RC Scope at f9, SBIG STXL6303E Camera and PME mount at itelescopes Siding Spring Observatory.
16hrs of 3nm Ha, 40 min subs bin1, 3 hrs each of 3 nm SII and OIII 20min subs bin2.
Processed with CCDstack, Star Tools and Photoshop.
Ive had a few goes at this over the years, each time a bit more data and a bit less overt over processing .
Thanks guys. If you mean by best the whole thing?, then no, many others have done far better. Peter, Stars are offensive by default, they intrude and are unnecessary, a distraction. Anyway, if accurracy is important in Astrophotograhy, then if you were this close to see that FOV without a telescope then you would not have the view spoilt by those stupid white dots.

ROFLOL well that says it all - brilliant shot, and interpretation
Ah Fred, have to say that looks pretty cool mate, the mega data with a bit of FL has paid off, even without the stars ...you've done something very similar to this a few times now so I wonder if Jase will give you a hard time too particularly given your setup and location now I don't mind
This snap shot prompted me to revisit my recent AG12 and SX camera data on this (that Jase lambasted me for ) to try to squeeze some more out, it's close although slightly noisier aaand not bad for 1120mm FL and F3.8 I guess ...buuuut you win ..mine has more stars though
No, Jase doesnt hammer me. On what BTW, whats he complaining about?.
Your eagle has a lot less data, so thats good work, wouldve been closer otherwise. And yes, FL helps too.
BUT, your f3.8 is a killer over my f9, you have a huge advantage there. I had a serious go at the "Devils mask in Pavo" after I saw your excellent post and couldnt get near it, even with 20min subs in dark skies, it appears to be very dim. Such was the difference, I didnt bother posting mine ;-).
I was somewhat waiting for this part of the image Fred. Part 1 (the tower) and Part 2 (the donut) was a good build up, somewhat teasers for main act, Part 3 and wow, what a knockout. Agree, ditch the stars for the extreme close up. They are too distracting and take away from the glorious pillars of creation. Must feel good to have near endless clear skies and great seeing. Looking forward to your next instalment.

Yes, Fred's gone starless eagle before. I count only 5 renditions of the eagle, two now starless. I'm afraid you still win Mike with your 10+ renditions. There's still time in the season for a few more. I am indeed green with envy of Fred's set up and location, so much so I'm moving my 12.5" RCOS set up from my current remotely controlled observatory, up to iTelescope SSO where Fred is.
I might add Jase, that if starless greif ever comes up again, you pretty much started all that on IIS with the suggestion I delete them on my M8 APOD . Too many eagle renditions ?. Nah, can't have too many of those. Or do you want me to switch to M42?

Oh ha ha yeh well, maybe do a recount and add up the total exposure time then buster!! ah yeahhhh, so there besides I have been imaging it for 10 years!
