Description

Another test shot. PowerShot A560, ISO 800, 15 sec subs. I think I'm settling on 15 sec subframes to avoid smearing the stars, and I got a bigger SD card so I can take more of them to partially compensate having such short exposures. This is 127 15-sec subs. I'm still having huge issues with amp glow and there doesn't seem to be anything I can do about it. I'm also exploring various options with DSS stacking. This set was with a low star detection threshold to pick up lots of stars, use of darks and biases, median kappa-sigma stacking, and use of a subset of the whole data set. I'm uploading it because I want a plate solution.
