As some of you will be aware, I've been working on Tarantula for a couple of weeks now with many challenges along the way.
I've got around 3.5 hours of useable lights now, which is by a long shot the most lights I have ever accumulated. It's not going brilliantly, and I might give it up, as I'm not seeing significant improvement between 1 hour and 3.5 hours, and doubt another 3.5 hours or more would improve that.
In any event, I've got a problem with my flats. I've done it twice now (re-took flats after I saw it the first time).
Apparently I double deleted my Tarantula Nebula, so I can't restore it and I don't really want to stack it again as I know it's faulty. Regardless, I had the exact same issue with my Centaurus A Galaxy, which I didn't delete. I have linked below, and have include a shot of the issue.
What am I doing wrong? My process is to get a white shirt nice and tight over the dew shield, put an iPad with a white screen against it, and take the flats. But I have this very odd 'banding' issue.
Can someone enlighten me?
