Looks pretty nice to me Daniel.

As Fred said, pick one exposure setup and stick with that...

I think either the 8min ISO 800 or 6min ISO 1600 would be the way to go...

If you stack 5min ISO 400 subs with 8min ISO800 subs and 6min ISO1600 subs, your longer exposures extra detail can be rejected by certain stacking modes, doing an average combine of these exposures will remove some of the deeper detail from the longer sub, as it will use the average pixel value... the 5 min ISO400 shots will have much lower pixel values than the 8min ISO800 subs, and hence, precious data is lost...

For MOST targets, just run the longest exposures you can at the ISO level that produces good results without too much noise (noise shouldn't really been an issue if you're taking a decent amount of darks.)

Good going, looks like you're coming along nicely, I look forward to seeing how you go with your reducer!
