Description

This image is taken from the 13th annual Encounter of Astrophotography of Brazil (EBA). Such a nice experience to spend a week under dark sky with friends.

The SH2-1 and SH2-7 are a delicate combination of faint reflection and emission nebula in the Scropius region. On first two nights I planned 7 hours for this target but was only able to get 1.5 hours due to cloud and power outages, after a inicial processing I was really suprised on how much information can be extracted from the dark site. Then on the third night I decided to dedicate more time into this target and finaly got around 5 hours of data. I am so glad I did even it means reducing the aquisition time for other targets. 

On processing the chanllenge really lies the balance between the refelection and emission nebula. As both are so faint, it is easy to overpower one over another. I decided to upload both version, LHaRGB and LRGB. frankly I like them both, what about you?
