The outer shell of NGC 6164/6165 is really dim

That's looking very cool.

Thanks, John. About time to put it all together...

Hello all
When I spotted Rick's post I asked him if he was interested in creating a collaborative, composite image given the excellent detail 32 hours of OIII exposure revealed. I had several hours of HQ Ha data plus RGB acquired with a 12.5" RC so the image scales were practically identical.

Anyway, total cumulative exposure time is 43.5 hours and the result is here.

thanks to Rick for donating such great OIII!

Hi Martin,

That's a very nice RGB/NB combination. I would have rotated my camera 45 degrees to get the diffraction spikes lined up if I had known in advance

I'll have a go at a Ha/OIII bicolour when I get a chance. Travelling on business at present...

Cheers,
Rick.
