Description

A project spread over 3 nights and 18 hours in all in 2021 and 2022 - very strong OIII and SII radiation facilitates color management - if the basic data is of good quality, BlurXTerminator is still useful for processing RGB stars - the management of the 'halos' of the stars is extraordinary!

Personally very happy with the result, waiting for the next improvements ;-)

Ha : 28x300 + 26x420n sec
OIII : 30x300 + 18x420+9x900 sec
SII :  30x300 + 27x420 + 9x600 sec

18h with Tak FSQ-106 and FSQ-85, EM-200 and EM-11, ASI ZWO 6200 and 2600 -10deg bin1, Astrodon HSO 5nm, stacked in Pixinsight.
