Caldwell 33 in SHO

Added¬†data so now have about 12hrs of subs which is record for me (with the slight problem that unstretched image looks almost processed ūüėĄ). There's some finer detail with better contrast now.

 

I tried using starnet to remove the stars and process the gas but that resulted in mushy gas. Instead I used the starnet star-mask applied to the original image to tone them down a bit in the final stretches.

 

I'm still messing with my processes, now using ez-denoise (which was an excellent tip - thanks Bryan) in the first phase and convolution in the final stages.

I would appreciate comment and criticism, you never stop learning.

It looks great, although the bright green is not to my taste. Is this an OSC image, or did you use your 1600?

ūü§Ę¬†Yes it is!¬†Yes, using the 1600, Its mixed as SHO so I cant see how to avoid the green I have tried a few other combinations but they all look pretty psychedelic.¬†

 

I just did an arbitrary SCNR set at 0.7 and this is the result which is  easier on the eye but the hydrogen as lost a bit of impact.

A normal combination for this object is to use just Ha and OIII in a HOO combination. The HOO comes out like this.
