Hi Lester
That looks pretty nice is this LRGB or OIII etc?
I have never seen those two sets of spikes on the inner ring before, do you think they are real or are they some artifact of your imaging system or processing?
A quick search of net images of this object show nothing like them..?
Here is a pretty sharp Earth based image done with a 20" RC at Mt Wilson Observatory - known for its great seeing... not sure I can match any features to those in your shot

The central star in yoru image looks a bit strange too, like it's out of focus..?
Still, looks good
Mike
