Description

A fun project that I tried out over the summer. Processing felt easier on this region compared to when use the same Rokinon 135 mm  rig to image the region around the North America Nebula. I collected a set up luminance data that really failed to bring anything positive. I used the Ha for lum and as seperate not sharpen Ha layer for Ha enhancement.

I have attached the starless Ha layer in Image B which I find particularly mesmerizing. 

Definitely a large improvement from 3 years prior with my T3i modified and 135mm cannon telephoto lens as can be seen below.
