Description

Cepheus Pilars (NGC7822) in Hα-SII/OIII/OIII+rgb.

It's a mosaic of 2x1 panels providing a original drizzle resolution of 12K and reduced to 3k for showing purposes.

Was challenging acquire and process all that amount of data, more than 160 hours of integration time in two panels of 80 hours each one.

It was captured in 18 sessions, between September 10th and October 15th with my dual setup.



NGC 7822 is a young star forming complex in the constellation of Cepheus.

The complex encompasses the emission region designated Sharpless 171, and the young cluster of stars named Berkeley 59.

The complex is believed to be some 800-1000 pc distant (3,000 light years), with the younger components aged no more than a few million years.
