I wanted to shoot something while the almost 3/4 Moon was up and that wouldn't be affected too much by it or suffer from gradients etc....the seeing was ok, so something smaaaall....
Well, at the other end of the planetary nebula spectrum from The Mighty Helix Nebula....is the tiny Saturn Nebula
. A favourite visual target of mine through a scope on a steady night
The inner ring of NGC 7009 spans just 25 arc sec of sky and the overall dimensions out to the ends of those bright Ansae are about 45" X 35" making it a challenging object to image, especialy at 1120mm FL
. About a third of a light year across and some 3000 light years away, NGC 7009 is a tiny planetary nebula in Aquarius.

The Saturn Nebula
I'm thunking... this might be similar to an eyepiece view through a very large visual scope, if our eyes were much more sensitive to colour at low light levels...
There is actually an extremely faint diffuse mottled OIII outer halo, many times the size of the main nebula but this would have required a fair bit more exposure and under no moon, you can see it in this awesome
