    M15 globular cluster wide field

    Hopefully there is no true black in there. None shown on histogram. I always find it difficult to decide how dark the sky should be, I think we always perceive it to be darker than it is in reality.

    No, I find 30 secs is good for the nucleus. It is difficult to strike a balance between core and outer regions. I find I can do more with DXO than trying to modify in DSS but that may be because I understand the former better. I think the more frames you take the better the outer regions will be, I took 99 but for some reason DSS chose to stack only 55.

    At last a night with few clouds. 55 x 30 secs ISO1600 stacked in DSS - Canon 80D + ED80
  13. Great explanation thanks. No. 4 seems to fit in well with the slow movement.
