Hi all, I thought I’d reach out to the group as we use the same camera. I haven’t had my AA183M for long. I have completed a couple of broadband images which at my level I’m quite happy with. Anyway I thought I’d give narrow band a go on the fish head nebula. I have so far got 2 hrs of SII at unity gain and 48 offset Using 240s subs, but my image shows no detail of SII. So if I do 240, or 300s should I be increasing gain to lower noise, smaller well or decrease to improve dynamic range? My setup is running on a sw 72ed scope. Any input would be greatly received.
Thanks Roger
