Popular Post +Derbyshire Dave Posted January 27, 2020 Popular Post Share Posted January 27, 2020 Well, I need some more data obviously, but still fancied having a go with what I had, I have been so desperate for data! This was taken last Monday and Tuesday, 21 five minute Ha, 18 five minute Oiii but only 7 five minute Sii. Draks and flats applied, I'll come back to this if it's ever clear again.

Most of my narrowband images dont have less than 4 hours of each filter, preferably more 😊 Edited January 28, 2020 by Sheila +Derbyshire Dave 1 Link to comment Share on other sites More sharing options...

+Derbyshire Dave Posted January 29, 2020 Author Share Posted January 29, 2020 Yeah, indeed. Thinking about noise smoothing algorithms I’ve already applied, I guess if I had buckets load of subs, I’d have to compare directly between a small and large number of subs before much post processing was applied.
