Update after the black horizontal line problem:
Using my 8" f6 Newt -
I finally got to do a proper star test after I adjusted the pot in the QHY9 mono.
It's much better - I had to really stretch it with HDR toning to see any black line.
See the pic of Alpha Centauri.
I also did a Ha 20 minute bin 2x2 exposure of the statue of Liberty Nebula
which came out quite well.
I also took a fair bit of LRGB of the same target.
I have a lot of processing to do.
cheers
Allan
