After the CTB1 experiment – M42 was well-placed in the South and I managed to get 10 x 3-minute subs before the cloud rolled in from the West. This is pushing me to get 100 x 3-minute subs just to see what it looks like.
What is very interesting from this image is the lack of ghost flaring from the very bright stars. The Hyperstar 3 gave a lot of ghost flaring from bright stars, but in the Hyperstar 4 Starizona seem to have got on top of that problem. Well done Starizona!
