Thanks Glen - gain 164 IIRC. Hopefully the weather will find some kindness so I can catch some more subs through the narrow letterbox of opportunity

Thanks Colin - yeah I figured it'd be a good object to get some data in all three channels. I've tinkered with bi-colour and blends, but...

Thanks Rodney - was certainly a random night, but I've no doubt a more selective night might grant better resolution still.

That said Eta C is a nice big bright DSO to get started on - Well done!

Thanks Andy - was nice to get some good signal in all three channels, I think that really helps understand what is there. Still, very tricky... and having played with a few different channel renderings, I can understand why SHO is popular...seems to help bring out the contrast. I was surprised that the OIII data was so much sharper (by FWHM at least), but then it is the shortest wavelength...certainly meant I had to practice my star masks
