Hi Bobby,

thatīs a nice shot with pinpoint stars! If you want to you can compare it
with our LRGB shot:

There is one difference in our images: your image has a color shift to blue
in the middle of the frame due to the hot spot of your scope. Such hot spots
which come most of the time from the tech pan negatives (higher contrast)
will most of the time result in such color shifts. I had them too and I was
working hard to get them away....

Merry Christmas!
