Hi,
Well tonight I had another go at M42
.
Tonight I still used the 8" Newtonian at prime focus, but, rather than 1 28 second exposure, I thought I would give stacking a proper go.
Focus was better tonight
and I mixed up the exposures just to see what would happen.
Exposures were made up of:
ISO400 - 5 second x 5, 10 second x 5
ISO800 - 5 second x 5, 10 second x 5
ISO1600 - 5 second x 5
The final stack was made up of 22 images in registaxx and I also did Histogram processing here.
Well...at least it is an improvement
and any advice on how to get better data or process better is much appreciated.
