Quote:The camera used was a Panasonic Lumix G5 with a 20mm f1.7 lens looking into the eyepiece of the image intensifier unit (a Micro Monocular) - afocal photography.Cheers.

Quote:The multitudinous specks are indeed noise, or scintillation, as it's called with intensifiers. Stacking a number of images would significantly reduce their impact.Another strategy would be to use a scope working at a faster f/ratio, and/or employ a focal reducer. This would form an image having higher surface brightness, thereby increasing signal to noise. The result would be a smoother, 'lusher' image, especially if the gain can also be dialed down.
Quote:Generally speaking, the stronger the filtration the more the scintillation. My 12nm Ha filter shows a lot, less in darker skies. My Orion SkyGlow photographic and my Lumicon Deep Sky show noticeably less, even in more LP environs. All experiences with naked eye viewing, not photographically.BTW Glenn, my IIE has automatic gain and I think most, if not all others, are the same. So gain is not normally adjustable on IIEs. Think of looking over the battlefield and an artillery burst happens nearby. Self survival for the image intensifier tube.Agree with dtripz, more pics if available.
Quote:Well done! I'd love to see some more if you have. Out of curiosity how do these compare with looking through the tube with your own eye, also what light pollution zone are you in?
