Hi,
Anyone apart from me using the LRGB filters from Player One Astronomy?
I have got the curves for adding them into PixInsight via Filter Manager.
Please PM me so I can sent then to you in a *.zip file
regards Rainer
PD I also have the filter curves for HOS if necessary but they need to be converted into a readable file for PixInsight.
How is the quality of the filters? Halos? Reflections?
I looked at them and like the transmission curves (sharp cutoff and no gap between G and R)
Hi,
The image below was taken with this filters

About halos no idea. Need to take an image of the Horse head nebula as the star Alnitak ias a PITA in that area 🤣
quote”(…no gap between G and R)”, yes, I was wondering about that but I guess as Sodium lamps are getting history we have no more light pollution in that yellow area. Now the PITA of the new light pollution is the strong blue light emission.
I am a bit surprised by those straight lines as well as the nearly linear transmission and compared the curves in PixInsight. 🤔
I took a spectrum of this during a cloudy night and it looks like this

and below a comparison between Sodium and LED light pollution, not a good one, but you can see it clearly to where the LEDs went

STOP. For that image I did not have the transmission curves of the POA filters. I used ZWO curves.
Let me process it again now that I have the curves.
Grüße Rainer
