IC 5146 - Cocoon nebula
« on: 23:37:03, 17 September, 2012 »
Sooooooooperb conditions on the Friday night @ Kelling... almost as good when I took this in the early hours of Sunday!

Narrowband from home.... Colour at Kelling!

6x600s Luminance binned x1, 6 x 300s RGB binned x2... because I can  :tease:

Processed entirely in PixInsight (longer workflow than I am used to) but I LOVE the result. Only the minimum processing - LRGB stuff as per PI workflow (background neutralisation, colour calibration), DBE (which hardly did anything with this flat field!) slight curves to reduce the background, and "SCNR" to remove a little of the green tinge.

Scope : Altair Astro 102mm F7 triplet with flattener
camera : SX SXVR-H16 (@ -20 degrees setpoint)
Guide : Lodestar on a ZS66
Filterwheel : Quantum 7x2" electronic wheel (Using Baader LRGB filters)
Mount : the ol' sexy black EQ6 pro

One of my fave objects... I love the star colours in here - decided not to push them too much to leave them more natural.

I like this one at this image scale.  It shows the dark lane and the nebula really well.  Good "3D" look about it.  Those foreground stars in front of the nebula really look closer!

Now that's what I call a top draw Astro Image !!!

I'm trying my hardest but I really can't find anything to fault.... arrh, just had another look... you need to crop out the red band down the left hand edge.... phew... thought you'd posted the perfect image  :rofl: :rofl: :duh: :rofl: :rofl: :tease: :-*   !

Only messing with ya... it's a stunning image mate... IoM nomination coming your way !

Thanks very much, chaps...  (Si, now that my eyes are staying open for longer than 10 minutes, I see it now  :thumbup:)

When this popped out of PixInsight, my jaw dropped... just goes to show what excellent skies Kelling can offer...

That's another target that takes advantage of those dark skies! Lots of stars and good contrast.

But yes, the red band down the left is pretty amateurish.  :laugh: :laugh:

I like that one Phil, especially the contrast of the dark lane.
