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 hoping someone here can shed some light. I used APP to stack 30x300 sec light frames shot with an ASI294mm through an Ha filter and got noticeable horizontal banding. I've re-run the stacking multiple times and have the same result when I run with no calibration frames. Individual light frames look fine - I've gone through all 30 and can see no banding but when I integrate all 30 in APP, the banding is quite noticeable. For simplicity I've ran it with no change to default settings. Can anyone suggest what I might be doing wrong or if there is a setting I should be using?

never mind, think I figured it out. the horizontal banding was an artifact introduced by USB connection. Moved all files to local hard drive in laptop and re-stacked and the issue went away. Cheers!
Great and thanks for sharing that. It happens now and again indeed and has become the usual question to a user when it's super-weird looking or indeed seemingly random interference. 🙂
