I want to make a big mosaic of the area around Deneb and Sadr.
Here is an impression, it is a mosaic of 6 panels.
What do you think of this?
Exposure times can be kept short.
An hour per panel is good enough.
I do make 50 subs of 2 minutes per exposure time because you usually have to throw away a number of subs.
At least that's my experience.
