Description

Improved: LBN 455 / IC 1396 - Cepheus (Cep)
Version D

I was not happy with the stars' poor appearance in all prior versions. After full re-processing, including a different GHT stretch  in Siril, I used several layers layer modes in Gimp to shrink and isolate the stars while also trying to get a more crisp and 'sparkling' appearance. I'm quite satisfied with the result now.

LBN 455 / IC 1396 - Cepheus (Cep)

Though the stars are quite nice to the corners when shot with the wonderful Samyang 135 mm f/2.0 wide open, I am a bit disappointed or clueless about the overall appearance after 4 full hours of integration time. Probably the almost full moon had a serious impact and my unmodified 12 years old Canon EOS 7D  can't deliver much more.

Hoping for clear nights around the next new moon to try it again (or add more date to these).
