Adding light polluted data to dark sky data
I have some Andromeda galaxy images I have acquired from a couple of different dark-ish sites SQM overhead of 21.7 to 21.9 (though Andromeda is only just above the light pollution domes and have gradients, but overall I consider very good data)
Is it worth me trying to add to them at my comparatively light-polluted farm (SQM 21.3 overhead) where I would be imaging at 20 degrees through the light dome over Coolangatta ? I understand I'd have to endure roughly 6.3 x the amount of imaging time to match the dark sites (assuming 2 SQM magnitudes of sky lightness difference - maybe worse).
In other words is it worth mixing small amounts of good data with lots of "bad" ?
(I use a 1600MM-Pro, 36mm EFW filters and a 300mm F2.8 lens.)
thanks.
