V nice, thinking of going narrow band for next season. Hope I can get as good an image as this. Roll on August!

[brrttpaul]

thx simmo, its probably a very average image but I have no regrets switching from OSC to mono, just wish my processing skills were better

[Adamar98]

I’d be more than happy with that!

Thanks. Can i ask why you binned and what gain you used.

[brrttpaul]

the gain was unity gain think thats 139,  The binning was because I didnt have much total exposure
