New to the forums here, and really glad to be part of a group of very cool and smart people.
To speak in brief about myself, I have taught for years in state park settings, combining astronomy science with native, asian and greek star myths, and constellations painting via pointer.
Recently decided to try something new in the NV field, and picked up a P8079 non-HP variant.
Got it all rigged up with 4 AA's, and a nice tripod mount.
Dug the rubber away, and discovered the gain control.
It seems that the non-HP variant, is differentiated from the HP to the extent that gain control is not automatic.
There seems to be a single gain adjustment screw, rather than the two found on the HP.
I thought that manual gain would be a plus, but I have been unable to secure any image other than a fully washed out green field.
Adjustment of the screw merely dims or strengthens the green, and I cannot get any detail on stars or even closer objects such as trees etc.
It's just a washout. Am I missing something here? I have not yet added a lens.
As the non-HP seems to be less common, I have not found a manual anywhere on the web. Does anyone have one?
Essentially brainstorming here on the status of this tube, and wondering what I could do from here.
