A long exposure of M31 to get the very faint envelope visible with a good signal to noise ratio. It sounds quite weird but M31 is a difficult object. The dynamic range is huge but I gave it a try. LRGB = 300:357:167:300 minutes. The 167 minutes for green was a little mistake. I put in 100 times 100 seconds instead of 100 times 180 seconds. Mike M31_P14_LRGB_300_357_167_300min.jpg

Hi Mike, That is deep. I cannot recall seeing anything showing quite as clearly how far out it extends. Great image and I expect a lot of time creating the stacks. Am I right in assuming that the outstanding exposure time on the job queue is to collect the ha data to be added later? I recall Steve suggesting adding some ha earlier on. Cheers, Ray
