Apr 29 2026 APP 2.0.0-beta42 has been released !
New improved Normalization engine, Fixed random crashes in integration, fixed RGB Combine & Calibrate Star Colors, fixed Narrowband extraction algorithms, new development platform with performance gains, bug fixes in the tools, etc...

Update on the 2.0.0 release & the full manual
We are getting close to the 2.0.0 stable release and the full manual. The manual will soon become available on the website and also in PDF format. Both versions will be identical and once released, will start to follow the APP release cycle and thus will stay up-to-date to the latest APP version.
Once 2.0.0 is released, the price for APP will increase. Owner's license holders will not need to pay an upgrade fee to use 2.0.0, neither do Renter's license holders.
I'm trying to register two different focal lengths - 135mm widefield taken with an ASI 2600mc-p 3.76pixel and 380mm FL taken with an ASI 2600mc-p 3.76pixel, I've read through some of the posts that have asked the question, but I absolutely cannot get the two images to register. No matter what changes i make in module 4, i continue to get the same error message:
Please choose another reference frame or,
adjust star analysis paramters to increase the
amount of detected stars.
I've tried different star parameters in 3) and different parameters in 4), but nothing. I am frustrated.
Would someone be willing to help?
Thanks.
I guess you tried not selecting "same camera and optics" and such? Does it properly detect stars in both frames or does star analysis already fail?
@vincent-mod Same camera and optics were disabled. star analysis in module 3 does not fail. registration fails.
I've tried mosaic, normal, i use the different projective models and the various modules within the registration module to no avail.
I've also tried combining to final images (multiple subs) and that did not work. I then tried stacking individual subs from both focal lengths and it hangs up at 80-percent on module 4.
Ok, thanks for the extra info. I think I need the data to be able to see what is going on.
Go to https://upload.astropixelprocessor.com and use upload as username and upload as password.
Create a directory named “sj_chavez-twoscopes” and upload in there. Thank you!
@vincent-mod Awesome!
I'll upload the images tonight.
Thanks.
Hi,
So I'm looking at the data right now. It seems like you have a lot of light pollution in the final integrations. Did you use any calibration frames? I think it would be very helpful if you could upload, say, 10 good subs from each scope and the calibration data for them as well.
@vincent-mod
I'll load what I have tonight. Thanks.
