Maybe you used the Bat mask on this star though?

Do you use focus software?

Hi Josh,
The Bahtinov mask was used for Alnitak which was at the edge of the frame.
The collimation was a bit out & adjusted it since then.
I should have used 1x1 binning not 2x2 for focus.
I am unable to use the EZCap QHY9 focus software.
The focus part of the program just doesn't work.
I use it for all other capturing.
We'll see what I get next time.
I will really try to nail the focus.

cheers
Allan
