Description

I really wanted to enhance the stars of my previous version, so I made some RGB 20 subs of 60s exposure for each R,V, B, just to get the stars and colors.

I used Starnet++ and Photoshop to clean out the stars of the SHO image.

So this is the new version with colors of the version A and B mixed , and RGB Stars shape and colors.

6 nights : 16/17, 26, 30 September , 3, 5/6 and 26 October,

54 SII Subs @300s (gain 139, -20°C)

63 OIII Subs @300s (gain 139, -20°C)

104 HalphaSubs @300s (gain 139, -20°C)

=> 221 subs @300s about 18.4 hours of exposure

20 Blue subs @180s gain zero and -20°C

20 Green subs @180s gain zero and -20°C

20 Red subs @180s gain zero and -20°C

=> 60 subs @180s about 1 hours of exposure
