Description

I continue to catch up on my processing que from last year. This capture was a quick 5 hours in mid November. Nothing exciting, but thought it was fun to have a wider view of all the Ha signal in the region. 

SH2-173 is an Hii region in Cassiopeia approximately 8.8K light years from Earth. The central nebula meassures 80 light years across.
