May 27 2026 APP 2.0.0-beta45 has been released !
Fully Multi-Threaded LNC, many improvements for the registration engine, platform upgrade, and further tuning of internal memory consumption and memory release back to OS.
Apr 14 2026: Google Pay, Apple Pay & WeChat Pay added as payment options
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.
Hi there !
I'm new user to APP. I have purchased this software cause i have inform before that APP can stack images from different nights, iso's, f.stops....
So, i have here data for Hear and Soul nebulas from 2 nights.
I also have darks and bias frames, don't have flat frames, cause i wasn't at my home and i couldn't leave camera there to do flats later 🙂
Is there any other tip for shooting flats ?
I want simplest procedure for stacking images in APP.
Can i load all lights from 2 nights together, also darks and bias frames ?
Any tip or suggestions would be nice.
Best,
Matej
Yes, this is very simple to do. On the first tab, you have the option at the top to choose Multiple Sessions. Pick that. Then select lights, load in your first night of lights. It will ask you which session, pick session 1. Then select lights again, load in your second night of lights, it will ask you again which session. Pick session 2 this time. Then do the same for your darks, and bias. Then on the integration tab, you can choose to integrate them all together into one image, or you can choose to integrate them into two separate session images. I have a tutorial on my website showing how to do this.
The easiest way too do flats is simply take them with your scope setup at dusk before your imaging session - while your rig is pointing to the NCP. Take the flats with auto exposure, ISO priority. Later you can do PA when the stars come out and you're good to go.
Another way to shoot flats is to use a flat panel. The advantage is that you won’t run the risk of getting stars in your flats. The downside is that you’ll need a panel that completely covers your telescope. If your telescope is small enough you can use an iPad if you have one. Simply load a blank document and make sure that true tone is enabled.

Thanks for your reply !
I have already tried in APP to stack images, before your reply, but i have loaded them all into one project, no multisession and results were the same.
Both nights were integrated together.
But next time i'll work like you mentioned, if i'll have more than 1 session.

Well, i don't have so advanced equipment, i'm shooting with camera, tracker and different lenses. 🙂
