Mar 28 2026 APP 2.0.0-beta40 will be released in 7 days.
It did take a long time to have the work finished on this and itĀ will have a major performance boost of 30-50% over 2.0.0-beta39 from calibration to integration. We extensively optimized many critical parts of APP. All has been tested to guarantee correct optimizations. Drizzle and image resampling is much faster for instance, those modules have been completely rewritten. Much less memory usage. LNC 2.0 will be released which works much better and faster than LNC in it's current state. And more, all will be added to the release notes in the coming weeks...
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 love what I can do with my narrowband images, both HOO and SHO, in the Color Combine tool. However, after I work hard to get the colors I want and then move onto Light Pollution Correction, it changes the colors of the object sometimes dramatically. It may not be possible but are there ways to protect the object from too much color change? Should I do LPC on the individual frames before the Color Combine?
Thanks!
Yes indeed, I would personally make full integrations of the seperate narrow-band images first, then correcting them with LPC etc. and only then start to combine them.
Thanks! I'll give that a try. This is the first time in a long time - maybe since I quit using StarTools - that I'm having fun processing. I stayed up til 1:30 processing old data with APP (and watching the new Dr. Who debut on TV....). I'm a real party guy.Ā 🤣Ā
PS I'm assuming that running LPC on grayscale and then background neutralization on the color combine would be the way to go.
Those are the best nights, at least if you like trying out various things whilst sipping on a nice beer and watching Dr. Who, you won't get frustrated very fast then. š
Use all frames of all narrow band data at once using the "multi-filter"and if true "multi-session" option as well. Everything will then be registered, normalised etc. to each other, which maked combining that data much better in the end. LPC can be done on the seperate full integrations, not 100% sure if background neutralization would go on that as well first... something for @mabula-admin

I didn't have beer but did have hot cocoa! I did use multifilter and multisession, three sessi0ns for two nights with one camera and one night with another camera

Hi @whixson and @vincent-mod,
Yes, for grayscale use LPC, and then perform Background calibration on the RGB Combine result if needed/wanted to get a good dark gray sky background š
