Hello, I also recently photographed the Pleiades, using the same camera as you. Do you use a UV/IR filter? I think the haziness in my images might be due to not having one.

Good evening. I haven't had the chance yet. I'm considering buying such a filter because when zooming in, stars appear a bit "puffy." They seem to "swell" in the red and blue channels. When shooting through a narrowband filter (hydrogen + oxygen), this effect is less noticeable. In this image, I slightly tightened the stars artificially in Siril using deconvolution.

Here I am, pressing the star net, I'll try with a filter if the weather allows. Let's see what that gives. Thanks.
