For some reason, I'm having trouble making a mosaic with NINA. This is my second attempt. No matter what I do, my picture always has an empty gap in the middle. This problem occurs only when I use NINA; I don't have it when using my Asair system. This is a four panel mosaic taken with a Sky-Watcher Esprit 100ED with a 0.65mm reducer. It's natural focal length is 550mm. Can anyone tells me what is going on?

Are you configuring NINA with a theoretical effective focal length, or a number resulting from plate solving?

It could be a number of things.  To help us help you, show a NINA framing assistant screenshot for these panels and your focal length camera settings in NINA.

Oh No! Not Operator error?

 

If I remember correctly, there is an overlap setting I saw when I was playing with this.

I believe it was a percentage of overlap.

 

But alas, it was my first and last time doing it. I wanted to stich the American Nebula into panels.

But I'm lazy and went back to my normal ways.

Which are not normal by most standards. But I get purdy pictures.

 

I'll take you past the fluff, and into the stuff. Mosaic appears to be another of those really cool little gems tucked away in NINA.

 

Cutting through the Dahlias, here is some meat on the matter.

Hope it helps you. waytogo.gif

Yes, the lack of an overlap, or at least a sufficient overlap is Suspect #1.

 

But I've made a number of mistakes on setting up mosaics, so I thought not to jump to that conclusion just yet.

 

That's a good reference.

 

Here is another that may help:
