OK, so after reading this
review , I decided to go the cheap way and bought Hoya Red Intensifier. It came at the same day as my new lens, so I took them out on Friday to test. Nothing very good, as the moon was very bright, but around the same location with same post processing settings (if anyone wants, I can attach RAW's for checking ). Sorry for quality, downloaded from Facebook (do not have originals now)... And sorry for spot, did not clean it (need to clean the sensor, I guess).
First is without filter, second is with filter, roughly same side of the sky. Lens Bower 24mm F1.4, 10s on 1.4
