M57 Once More

With a slightly better understanding of the techniques involved. I attempted M57 again. This is by far my favorite object. Biggest bang for the buck so to speak :) As you can see it’s a much better capture composed of 20x2 min exposures and an equal numberof darks. 150x10 sec darks and dark flats.

But notice the stars. They are not focussed properly and also are a smudge with a lot of bloom. Two things: Robofocus and IR Filter :)
