Hi !
Are there any plan for adding plate solving/astrometry in APP in future versions ?
I'm asking because I think it would be a perfect tool to make mosaics ; after star detection it would register all frames with a great accuracy and projection.
David
Hi @dav78,
Yes for sure, for several reasons. For mosaics, for star color calibration and possibly other reasons 😉
We first need to finish work on 2.0.0 stable with save/load settings and projects 😉 after which this feature is rather high on our priority list.
Mabula
Thanks @mabula-admin, that's a great news !
Indeed, solving and astrometry will have many advantages : true star color, projection correction and more.
I'm looking forward to see this 😉 !

I shot two series the other night with minimal overlap that I can't get to register. I was going to suggest either building in plate solving or using coordinates in the fits header to help. To help figure out what was going wrong I used astap to plate solve and write to the headers and then using Aladin to show me a frame from each sequence so I could see if there was overlap.
Thank you
Hi @szumi,
We will add it for sure 😉 How much overlap did the frame have? are there any stars in the overlap region. Normally, when enought stars are detected in the overlap region, APP will be successful in registering them.
Mabula
It was 5% at best with some stars. That was why I was chiming into this plate solving thread. I'm still waiting for a good night so I can shoot some frames that overlap which I'm sure will work.
Thank you for responding
Hi Szumi, @szumi
You are most welcome, yes 5% is very/too little. Even with plate solving, I would recommend more overlap if you want the sky geometry to come out okay when those panels are combined. Many applications use thin plate splines to register the image then, but the sky geometry will be off surely in those cases... so it is never really right with so little overlap.
