Description

Once Orion came back around this year, I was excited to see what SH2-264 capture would look like in SHO first and now creating a HOO rendering. 

I have really enjoyed creating HOO images after SHO captures. The power full functionality of GAIA data and spectroscopic color calibration for narrow band passes yields fantastic star and nebula color. I continue to add 0.3 Ha to the full value of O3 in the blue and green channels to roughly approximate an Hb coloring. I really have enjoyed the results since changing to this strategy. 

While only a one night capture, this project turned out exceptionally well. I used GraXpert again, which made a noticeable difference on O3 layer. I was shocked by all the detail and in the edge of the nebula as well as the channels that run through out.

SH2-164 often named the Angelfish Nebula is a large H2 region and ring  ionized by Lamda Ori (Meissa). This star is located 1,100 light years from earth and is a large B-class star large spectral output in the UV spectrum and surface temp of 35,000 K. The ring is thought be from a SNR 2-6 millions years old from a possible binary companion of Meissa. (via Wikipedia) 

On the lower right of the image, SH2-263 also is visible consisting of both emission and reflection nebulae
