EDIT...I CAN NOT UPLOAD PHOTO ..I will try later...

could not find this object the first time I tried so I tried to get my goto working which I have not used other than ten years ago on another mount..I like finding things the old way..but I could not so I tried goto without success so then I just used the dial on Dec. I was sure I was on it but nothing showed on screen with short exposure but happily I selected Ha dialled way up for 30 seconds and there it was not perfectly in the center but I was happy that I still had it..whatever it is But I will have to sort goto..the observatory is too small to use the finder scope all the time...I am happy I can just point the scope and find what I am after..years of pub pool

Anyways I only had a couple of hours so I took R,B, G and Ha R G B at 250 gain and HA at 400 gain...wild or what.

One minute subs, about an hour for Ha and about 20 minutes each for R G B but I took darks … so stacked Deep Sky Stacker, Processed in Star Tools, Photo Shop and Gimp. HEQ5 unguided mount with perfect PA at least the little crosses in Polemaster were exact 80 mm spirit, ZWO 1600 mono cooling at -15 degrees C Good Seeing but very cold moisture was not too bad.
Next step would seem longer exposures at reasonable gain and some flats and hopefully the washed out look will improve..but I am very happy I am already way past where I expected to be when I started...
The image was heavily cropped ..at first cause I was worried about oval stars but later I just though this crop looked about right..for me at least.
