Hello everyone,

 

another thrilling area in Cepheus constellation.  I had a hard time to add and ballance strong  H-Alfa emissions into that picture...hope I succeded. The H-Alfa image itself is in revisions table.  Anway starfield if just rich and beautiful as ussually in Cepheus area. This is crop of course for the most interesting part. 

 

Imaging setup:  Lacerta Newton 200/600, ASI 2600MM Pro, Astronomik HaRGB 36mm filters, SW EQ6-R, guided by SW 50ED Evoguide+ASI290mono.

Total integration time : 9h29ยด , Bortle 5 area - my backyard

Outstanding presentation of this beautiful area!

 

Your coloration and contrast makes for a very pleasing view.

 

I struggled with this target in Bortle 7 skies with an osc/l-enhance and never could get it right.

 

Well done Dave!

Thanks very much gentlemen ...as said the color balance after H-Alfa layer was added was not easy to recover (since it was very dominant here) , but I quess it is matching now.

This area is a tough one to balance for sure.  I had similar issues on mine, and if you continuum subtract the Ha and Oiii data, you get a very interesting structure too!      You've done very well.
