My first 15 panel mosaic worked out nicely for the most part, but I'm getting some registration problems as you can see in the attachment. This is a quick and dirty mosaic being used for framing purposes and thus there are no subs. Most of the 15 panel intersections are perfect. My overlap is 10% and LNC is 2nd degree and MBB is 11%.  

What should I change to improve these few registration problems? Many thanks!

Hi @rixon,

Thank you for your question and welcome to the APP forum 😉

This is a quick and dirty mosaic being used for framing purposes and thus there are no subs

So just to check out how the composition turns out I understand?

Most of the 15 panel intersections are perfect. My overlap is 10% and LNC is 2nd degree and MBB is 11%.

What should I change to improve these few registration problems? Many thanks!

It would be best if you can share which settings you used in 3) and 4, then I can give you some pointers 😉

How many stars did you detect/analyse in 3)?

Looking at the data, you should probably try to aim to detect up to 2000 -3000 stars with 10% overlap.

Kind regards,

It's Ha exposure of 300 secs on f3.1 refractor. On average around 750. How do I increase the number of stars that are detected? Should I just use the automatic minimum # stars target in the Analyse Stars tab and make it 2500? Thanks!

Hi @rixon,

Yes, for your mosaic, with 10%, try to increase the star count to 2000-2500 if possible 😉

Yes, increase minimum to 2000-2500, maximum will be double automatically.

You could also disable automatic minimum/maximum end set the kapp value to a value for which yoy find 200-2500 stars in all frames. A bit more or less should be okay.

The borders of your mosaic panels need to have enough stars detected to have a good mosaic registration with accurate optical distortion correction.

Let me know if the result is better 😉
