Hi all
With a very dark and clear last night, I went for Abell 21 the Medusa Nebula in Gemini, a rather "bright" object for an Abell classification.

8x10 mins ISO400.
Baader UHC'S and IDAS UV/IR filters, Baader MPCC coma corrector. Modded 350D. 10 inch f5.6 Newtonian. Off axis hand guided.

Seeing wasnt very good but transparency was excellent, and humidity low, but over 20 degrees so lots of thermal noise in the subs.

Mounts been set up in front of the garage for a while now, and was near perfectly polar aligned, great to be able to just plonk the scope on it , balance it and wait for it to get dark. Garage helped block most of the westerly breeze but the occasional buffet on the scope.

Nice image Scott have not seen this one before

good self critique

you may want too try with only an LP filter as I noticed with my IR cut filter it effects the red channel

Nicely done here Scott.
As already mentioned, some more date to this would have smoothed things up some, but for the time invested, it turned out well.

Ok, now you've had the taste of little or no setup down time, I think I can here you thinking, man, I just need an observatory.
Yes, certainly makes life so much easier for sure!

Cheers
Rich

Good capture Scott. I am planning on having a go at this in the next few days. Did a search for the Medusa nebula and yours was the only one to come up.

Thanks for the view.
