Cygnus 50mm // L-eNhance
Hello from Austria 🙂
I tried my new filter and got the following result.
The full quality is available here: https://www.astrobin.com/g6rtfv/B/?nc=user
Seems like it was a good purchase. 🙂
Yes it was 🙂
I am not satisfied with the stars because at f/2.2 there are red halos around them.
I still have to test whether this has to do with the lens or the filter.
I see what you mean on the full resolution. I think it might also just be the nature of these 2 signals combined, it's not always preventable.
Amazing wide field picture!
Concerning the halos: that's what we get as well when using our L-Extreme filter and even when using separate Ha and OIII filters. It is in the nature of stars. some stars are cool and therefore red, some are hot and therefore blue. The result is that red stars will appear brighter in the Ha channel and fainter in the OIII channel. Blue stars appear brighter in the OIII channel and fainter in the Ha channel. The result is red and blue halos around stars. There is nothing you can do about that apart from trying to reduce the halos in post-processing. I never really succeeded in doing that in a satisfactory way myself though so I learned to live with it.
Clear skies, Wouter
