Thanks for posting your data. I had a go with the latest edition (as of this afternoon 1.7.434) and the result is below. There were some quite strong gradients which were cropped out and to speed up processing I binned to 35% although this wouldn't be something I'd normally do on under sampled data...

Hello all, I'm trying to learn how to process with ST, and have been trying both the stable and alpha versions on a new stack of the Helix Nebula. The integration time is almost 18 hours under a very polluted bortle 9 sky, using a Samyang 135mm lens with a Nikon D500 DSLR, so the data is undersample...

Hi and welcome1 You are correct, If your dataset is under sampled and you need to drizzle to avoid that, then binning is usually not useful. The only time it may be useful, is if the drizzling (usually only available in 2x2 or 3x3 variants) was too much and you'd like to reduce the oversampling a l...

Hello, I am a new ST user. I shoot with a cropped sensor DSLR and a 135mm lens, so as I understand it, my images are undersampled. I have added an AZ GTi GOTO mount to my kit that I use in EQ mode and am able to do proper dithering. My question is: if I drizzle when stacking, I should not use the BI...
