M78 Nebula

M78 what a beauty!!! Well as you can see from my previous posts I am quite taken with M78. I think it would be fair to say its on of the “bluest” things in the night sky.

You can see from my previous post, the difference between a 1hr and a three hour exposure and the difference between a 44K JPG and a somewhat higher quality one (900K).

My image processing (and I consider that I have logged enough hours to be good, but still no where near Russell Croman or Tom Davis’ league)…..is as follows:

Calibrate all images with Darks and flats
Use Kernel filter to remove dark and hot pixels
Combine in color channels
Color combine
Export from Maxim DL as a TIFF
Use Levels and curves in Photoshop, according to the 4 Zone Method (Wodaski/Croman)
Remove any remainin hot pixels with healing brush
Reduce size of image and export to JPG

And the finished product I’m sure you would love to see…



My kids asked me what is it called? I said M78! "Yer dad, but doesn't it have a name like a barn owl nebula or something?" So I checked and no it doesn't have a common name. So lets take a closer look.



Anyway it does look nice......particularly in this wide angle shot that made APOD earlier in the year.
