Hi Uwe, I have the ATN PVS-7 2+ and I just received the Svbony 7nm Ha filter. I tried it out last night in pretty clear skies in Central Florida and couldn't see a darned thing, just alot of scintillation. Am I using the right brand filter? When I hold it up to a light all I see is deep dark red. It doesn't seem to draw enough light into the device. I'll take any advice from you and fellow CNer's. Regards, BTS
bobthruspace, I have read on other forums about using this filter with NV. People are happy. I don't have it.
Do you see Horse Head with him?
As an option, the PVS-7 does not have a gain knob and gain cannot be set correctly (for the object you are observing).
