As I took a look around while setting up last night, the distant hills West of town,  Granite Mountain  to Wolverton Mountain, looked very sharp and clear.  Hopes  were rising.  My guide stars Deneb and Scheat  were very  well behaved.  If I were a dog, I would have wagged my tail.  This picture was taken with my 8 inch reflector at f/4, using the ASI 183mm-pro, on a guided CEM-60 mount.  R=13x2min, G=27x2min, B=24x2min,  simulated L of R+G+B,  at  160 gain and a -15C temperature target.  Stacked in DSS,  developed in Star Tools and Gimp.

  I think that you have some good data there Gipht, but there is a bit of a magenta cast to the image.  Stars look good, so guiding was working well for you.

Thanks Gunny01.  I did not see that until you mentioned.  Corrected on my copy.
