Hello once again everyone!
Here is the next instalment of my "return to...." series. These are all my my second pass posts of targets I first imaged when I got into this hobby, They are mostly for me to measure my growth as an astrophotographer. This image is far from done but I am limited to exposure time as Orion still doesn't rise until very early in the morning. Once again, thank you everyone for your comments, support, and advice!
-John Bellisario
