Description

Still experimenting with the new rig. I'm struggling to know how long subs to shoot from my new darker skies. With these 5 minute subs the histogram is parked right over to the left making the data look clipped. I will need to experiment with longer subs.....

The Meade FR introduces severe vignetting which has not been completely removed by the flats and also chromatic aberration, which I think cannot be removed other than by cropping out the worst effects at the edge FOV, which I have not done....

Vers B - experimented with a technique to enhance saturated star colours by blur colour from surrounding star halo. Not a complete success, but my first attempt at this interesting technique.
