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 still trying to get a handle on interpreting the Star colour graphs and getting good accurate star colour. Trying to figure out how much my light pollution filter is shifting colour?Â
I've attached a screen grab from a recent calibration and trying to understand if I need to do anything additional to the settings, slope/etc? Â
Have I got accurate star colour? Thanks for any help.
Based on that algorithm that seems to be a good calibration yes. The data points are brought closer to the optimal diagonal line which is the expected trend. You can tell that the stars are nicely blue-ish and orange as expected and the H-alpha signal is correct as well. You can play around a bit with that reddish color and make it slightly more pink (which technically is more correct or redder as that's usually perceived as being nicer). In the end there is only the technical correct color belonging to the actual spectrum of the gas and stars, but there's no real "best" color as most is personal preference.
Great, thanks for the feedback.
So in a nutshell if I understand the graph methodology, I want the majority of stars to be along the diagonal, and around 90% or so to be positive, with the remainder negative (blue stars)?
