Its a really interesting looking emission nebula. I note several people out there have put this in their planetary nebula galleries when in fact it is not such a nebula. Mind you it does look like a planetary.

Thanks Paul. I am happy with this data and the 8300 matches the Honders quite well. I got some good O3 data as well. The strength of 12 inch aperture and F3.8 helping there.
I am trying to add more data to it as well and got some CDK17 data last night but the moon even with 5nm filters seemed to wash it out too much. Perhaps some of it is useful though. I'll have to process it to see how much it cleans up with flats etc.
Greg.
