Description


We have had almost 2 months of clouds and rain. Now it looks like I will entirely miss the upcoming new moon shooting opportunity. November 30 there was a small clear night sky opening and sadly it is the last actual single-night imaging session I managed in 2021. I managed only 4 hours of exposure, but I am happy with my result for this year.

The HOO bi-color processing method made it a little difficult to color correct the background, but it is ok for what it is.

70 total exposures split between 300 seconds, 240 seconds, 180 seconds. I decided to shorten exposures because I was concerned about light pollution around my house.

Photoshop - Stars from a stacked RGB image were removed from the RGB image with Star-xterminator.
Secondly, starless versions of the HA and Oiii files were combined in Photoshop and the RGB stars were added back into the image.
