Martin,
This advice is well received. Thankyou for your insight. I agree that using the V3 narrowband filter has caused the colour cast you mention of. I have to say to be honest the short integration from the imaging using the uv/ir cut was far more true to colour and although only half an hour spent it was showing far more promise than the hour of filtered integration using the V3.
I usually image at iso 800 as you suggested but tried a different tact lowering it to minimise noise- there was banding present in the subs as a downside which comes from lack of signal perhaps-
This was my first attempt using Ha and again you’re right- not much gained from the galaxy but the core did help sharpen a little.
Appreciate your tips.
Cheers,
Anthony.
