Struve’s Lost nebula with the Hyperstar 4

Clear Moonless sub-zero night last night so I was expecting some great results from the Hyperstar 4.

Managed to get 25 x 5-minute subs with good collimation, and the above image is the result. It’s terrible. Virtually no dust which came out well using the Sky90 array.

Must admit, the sky did look rather light, and I guess it was full of ice crystals. First time I’ve had that as an issue.
