QHY9 in-focus smearing problem
I went through a series of problems with a new QHY9 mounted on RC8 and what looked like random "hot pixel noise", After substituting cables etc, it appeared to be USB-induced noise from the pier USB hub-power 5V connection. All good now.
My present problem is that when I focus the QHY9, using Nebulosity's "Fine Focus" function and a reasonably bright star such as Peacock, I can get good focus, but the image on the main screen then shows smears to the right of the star, in effect making the star go very egg-shaped.
It doesn't happen if I use a QHY8 Pro in exactly the same setup, and I tried the QHY9 without the filter wheel and it still did it. I have not yet tried any other software. Clouds.....
Has anyone else ran into this problem and if so, solutions?
