    I get your point, and yes, it’s already moved from where it was when it was imaged. What you could see would depend on how far away you are from it. If you could now, suddenly, magically be at the edge when the photo was taken it would be some where else. Everywhere we look we’re seeing into the past.

    As a beginner, seeing this information really helps. Thanks for including it all and you’ve made a fantastic picture.

    I have a couple questions if you don’t mind: what does NB and BB mean and regarding the number of calibration frames, do those numbers represent your choice at imaging time or what remained after excluding any that you or the software didn’t like? Thanks!

    I’ve just begun taking astrophotos and this is an amazing photo. The weather hasn’t cooperated much lately so I’m trying to understand using Siril as well as everything to do with my new telescope and camera. Did you also have a dew heater on your camera/lens? Did you take flats and bias and darks too? Sorry if too many questions, you just seem to know what you’re doing as that photo shows.

    P.S. I don’t see any elongated stars. Ah, wait, I looked at the full res version on telescopius and I see the elongation. It seems to radiate away from the center of the image in all directions. More so as you leave the center. Something with the lens?
