HD Video Image Intensified Sky Pans at 2X new
      #5682793 - 02/16/13 03:28 AM

Last weekend from Mount Pinos, Calif, I took a few short videos while panning the sky and horizon in the subfreezing temps. Used a Gen 3 thin film intensifier in a Micro Monocular.

1) Orion, Canis Major and snowy Pine Tree Horizon
2) Orion, Taurus, Pleiades & snowy forest

When viewing, please use the 1080P setting for best quality. The video shows pretty much the same image that one sees when viewing with the naked eye thru the intensifier.
Enjoy.

Filtered or plain view? Nice location, hasn't realised it was so free covered.

Cheers

Peter

No filter was used. The sky was very dark and transparency was excellent. 'free covered'? You mean 'tree covered' or actually tree surrounded, right?

Yes, good old phone auto"correct" again! How do the different widths of h alpha filters behave under light pollution?

I have used 12nm and 7nm H-alpha filters. Under severe light pollution, the 7nm cuts out more light pollution than the 12nm and gives slightly higher contrast when using faster optics - faster than f2. When I use my telescopes (f > f7), I prefer the 12nm filter.
