Description

A reprocess of some old data from the southern Spain scope, a f/3 RC 8". The scope took 38 in Ha, at 5 minutes in length each, 30 in L at 5 minutes in length each, and 19 subs in R, G and B all at 5 minutes in length. Integration time was almost 10.5 hours. The most irritating thing is the massive halo round the star near the centre. I have tried everything to remove it, wavelets, star reduction before stretching etc... oh well. Thanks everyone...
