Description

Just can't resist imaging M42 over and over year after year!  would you believe there are almost 20k images of Orion on Astrobin?  Guess I'm not the only one year after year 😀. 

I saved capturing this beauty for a dark site and I was fortunate this year to get 1.5 nights clear on the new moon from Chuchupate elevation 5,700 Bortle 4.5.  God I wish I lived in such darkness!   It was cold as my camera -10C was 0%.  Capturing required some testing.  I found that due to the sky glow from LA and Bakersfield, I got better results when using a light pollution filter in this case the Antlia TRI RGB.  Processing was tedious but fun.  GHS did a great job stretching.  I learned I could mask (the Trapezium area) and stretch separately...so kind of a trick but no cheating 🤪 to bring them out. They are kind of a mess in this image, but the best I could do...there's always next year 😀. (I think I'll take 5" subs and then clone them in next year 😂).    I went for bold and lots of contrast trying to bring out all the surrounding structures.  APP for stacking did a fabulous job of removing the satellite trails which were in every sub.  (I used APP's latest version 2.0.0 beta 26 for Apple silicon.)   Since I had over 200 x 122.4MBs subs to integrate even my Mac Studio Ultra got hot...I had to put my lens duster fan on it 🤪.   Merry Christmas, pray for peace on earth and goodwill to all.  -john
