    Very useful tools. I can now rescue some images where I messed up the flats. Thank you for continuing to work on ASTAP - it's one of my most used astro programs.

    Very simple and quite effective tool, thank you Han.

    Siril has can stack with Drizzle. How do you do the same using ASTAP?

      Drizzle is not available anymore in ASTAP . Drizzle was in older ASTAP versions implemented, but the effectiveness was low to very low and slowed down stacking. Most people have now sensors with relative small pixels making drizzle more irrelevant. So it was decided to remove it.

    HI Han. Very interesting and useful. Unfortunately Ctrl then Right mouse doesn't turn on the circular selection tool on either my Windows 11 or my Windows 10 laptop. Tried every key option I can think of but it only ever turns on the rectangular selection tool. Any thoughts?

      Strange. You just have to hold either the CTRL or SHIFT key, then press down the right mouse button and pull the ellipse. Can you try again?

      @hk4197 Thanks for getting back to me. I have ASTAP installed on two machines, used primarily as an excellent fast plate solver. But on both machines I have the same problem. Cntrl or Shift followed by right mouse key always opens the rectangular selection tool. I've tried multiple times, rebooted both machines and swapped the mouses.

      I’ve got the same problem on my Mac. I’ve tried several combinations of Shift and Control. Nothing works; I always get a rectangle.

      Easy fix. Update to latest version. Works great!

    Why I get always black and white photo after stacking? 😖

      Have you set stretching (right of histogram) on auto. So e.g at "30 and low"?
