Had a Eureka moment
When debayering in Nebulosity i was not adjusting pixel size correctly.
20 5min subs, no darks ,flats or bias, will do later.
WO FLT110 + TMB flattener, Nebulosity , PS CS6
Could somebody please explain why i am still getting egg shaped stars on the edges when using the flattener, i thought it would be corrected.
I am extremely pleased with the result so far.
Any critique would be welcome.
Cheers
George
