Quote:Got another real-time HD video for you taken thru a Mewlon 250 scope and a Gen 3 image intensifier from a dark site. Magnification is 120 power. You'll get the sharpest video by using an HD setting. Enjoy! M82 HD Video Link

Quote:Is the scope operating at f12? Are the views similar to the eyepiece? You seem to like the cold!CheersPeterW
Quote: Just an aside - I'm puzzled by your reference to "HD" - does that mean recording the output screen via a HD cam or that the IIE is HD? Isn't the limiting factor the IIE screen resolution rather than the cam potential resolution. Just asking

Yes I am recording the video in HD mode (1920x1080/60i). This image tube has a resolution of 64 line pairs per mm. I'm not sure how that translates into pixel resolution. Since my Mewlon 250 is operating at f12, on a dim target like a galaxy, the tube resolution may be lower than 64 lp/mm. If I shoot the video in standard definition, it will look noticeably lower res than using the camera's HD video mode. BTW, my camera is a Panasonic Lumix DMC-G5. I'm already looking into finding a camera with even better low light sensitivity since the video it produces shows less detail than the naked eye view looking into the intensifier ocular.
Quote:can you upload drawing on how you record fromm IIE device
Quote:NiceBut it looks heavy what is weight?Does first lens sit afocal to eyepiece?
Quote:and how is it mounted to scope?
