Scientific/David Levy 6 inch Mak-Newt... M-33, 25 ten - minute
subs at iso 800, acquired and calibrated with warm pixel conversion
and first color in Nebulosity 2.1.9a, curves and gradients in
Photoshop. The scope is a 152mm f/4.8 piggybacked on the 12 inch
The moon had set and the sky was good.... stable to an arc second,
but visual magnitude of only about 5...
I am homing in on this scope,
and have almost eliminated the flexure. Also, for this image,
like the cocoon done earlier, I avoided the usual DDP in favor
series of small curve adjusments in an attempt to maintain star
color. It was pretty successful I think, I didn't use any enhancement
stars for this, and only a slight Noise Ninga on the background.
I plan to add some H-alpha during the coming moon phase...
