New improved internal memory controls should now work on all computers
May 1 2026: APP 2.0.0-beta43 has been released !
Improved internal memory controls (much more stable and faster on big datasets), fixed CPU image viewer, fixed Narrowband extraction demosaic algortihms.
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...
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.
Hello,
if I'm lucky tomorrow I'll be able to capture comet C/2017 K2 as it passes M10. Can I also capture here with a mono in RGB, and then stack that? Since the comet is moving, I have concerns here. I have only ever captured comets with an OSC. So it would be the first time with a mono.
In such a case, does it make sense to always record in R, G, B, R, G, B, R, G, B, etc.? Usually I always record several shots from one filter, but here I would have to switch through the RGB filters, wouldn't I?
Or can I easily take 10 x 60 sec. red, 10 x 60 sec. green, 10 x 60 sec. blue?
Or better 1 x 60 sec. red, 1 x 60 sec. green, 1 x 60 sec. blue and start again?
What makes sense here so that APP gets a good image from all the data?
Thank you!
I think that's possible, however it will depend on the relative movement the comet has in your FOV. That will dictate how much it moves in between shots. If you're able to calculate that speed (or if it's known) and calculate how fast it moves over your pixels, it can tell you if that's possible or that you get misalignment on the comet itself. Wouter has notified Mabula so if he answers he may have some idea about it as well.
I tried to shoot comet c/2022 E3 ZTF in mono last night. I registered them in the comet mode. However I can not normalize the LRGB files so I can't open them in combine RGB. Is there a solution?
