I found some Hyperstar 4/M31 data from 2021-10-11 comprising 33 x 3-minute subs – so I added this to the 52 x 3-minute subs taken on 22-08-25 to get the result above. So now a total of 85 x 3-minute subs (getting close to the magic 100 
) and that’s probably the best I am going to get from this rig without going to slightly longer subs. Hyperstar 4 on a C11 on an alt-az mount on a wedge with an ASI 2600MC Pro CMOS camera.
