Description

It took me 3 months to gather all the data. I started end the of May and finished the end of August. This mosaic was pretty difficult to make due to the rich star field. I originally planned for half the amount of integration but after processing it I wasn't happy with it so I decided to double it. Getting the correct color so it looked natural was also difficult because i wanted to include the Ha data in the Synthetic Lum I made for the detail. I think I was able to find the right balance.
