Description

Huge emission nebula with a dark nebula in its center (5000 LY), with the star SADR (1830 LY – 39,000 x brighter than the sun) in the constellation Cygnus, and the open cluster NGC 6910.

2 cold nights in January and 2 hot nights in July for 111 x 7min (13h) of Ha, OIII, SII and 45 x 20sec RGB images for the stars – Tak FSQ 106 and FSQ 85 (reducer) – ZWO 6200 and 2600 bin1 -20deg – stacked in Pixinsight.Very happy with Pixinsight's new WBPP feature with Local Integration, and the ability to save 4 nights to integrate a single image.
