galaxy 5247
HI Rowland- I think I recall 30 darks and 60 bias frames - have not got any flats sussed for this scope yet - light box on order.
Another reason it may be noisy is that it was ISO 1600- first time I have shot at this ISO- usually aim for 800 ISO but when I started I was imagining I would only be able to collect an hour or so- due to weather clouds and Moon. If I'd have known I would have stuck to ISO 800!
