LDN 1217 (center of the field) is a Bok globule where dust condenses to form protostars. This is a very busy field....and an extremely star filled field in the constellation Cepheus. I reduced the stars to show some of the very nice nebulae and blended in the H-alpha data. There's 18 each LRGBHa subs @600s for a total exposure time of 15 hours.
Hope ya like it!
