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 have imaged the Cat's Eye Nebula in two consecutive nights using the same setup with a ZWO ASI294MC Pro one-shot color camera and the Optolong L-Extreme filter. If I stack the data from the first night, the results are as expected. The results from the second night show a strange color cast when I process them even when using only the standard settings and hitting "integrate" right way:
In the first night, I imaged at -10°C - the second night at -20°C for 300s per sub. Individual subs look like this:
Flats-, Darks- and Bias-Frames don't show a visible difference (except less noise @-20°C).
I have tried both, the Adaptive Airy Disk and the Ha-OIII color algorithm - both with the same strange result for the second night's data.
The normalization map files do differ significantly:
Other targets imaged the second night look fine and can be processed without problems.
Did someone see this behavior before and has an idea, how to deal with this?
Thanks for any suggestions!
Phillip
