I was lucky enough a few days ago to be able to capture the conjunction of the the Moon and Venus in Sagittarius. I shot it wide angle (150mm-ish or so) with a DSLR lens and Ha+[OIII] filter on a cooled ASI24MC so that I would also be able to pick up the Lagoon and Trifid nebulae. That worked out nicely and I got all subjects in frame. The Moon is (as expected) completely over-exposed, but I can live with that.
Now my issue is that over the 30 x 60 second exposures, the Moon has moved a fair distance against the background stars and if I stack the images, it turns into a white egg. Is there a way I can process my subs so I keep the Moon from a single sub and exclude its maxed out pixels from all the other ones?
I have a Mac and generally use Siril for stacking and initial processing.
