    Default DIY Image Intensifier for Telescopes



    I want to buy P8079HP and watch the night objects. Has anyone tried to use NT with Dobs?

    From the videos I have seen they will let you see dimmer stars but it seems to cut down on detail.
    Of course there is no guarantee that the person in the video was using them properly either so...

    I'm slowly looking at options for the refractor, being curious about using them for satellite obs or the smaller moons. Probably a wild goose chase, but...

    Satellite observations are best done with a tracking mount that has the speed and option to do it.
    Observation of distant moons I am not sure how they would work for that. Since they enhance all incoming light they may help or they may saturate the view to much to see small faint objects.

    The key statement is 'enhance incoming light'. They do NOT increase the number of photons that are caught by the scope. I have a notion that many believe that given enough intensifiers and gain that one can turn a 60mm drug store into Palomar. Not true. Photons are all one intensity it is the number of photons that make an object bright or dim. Bigger scope capture more photons. Intensifiers just amplify the few into a visible few, the images are IMO binary and not pleasing. A video integrating camera is a better way to go for near real-time viewing. Or just go to digital imaging for the ultimate in depth and dynamic range.

    Just my thoughts,

    Gabby76, yes the mount is the tricky (or should I say) expensive key to the whole thing. . I would enjoy the experiment of seeing what can and what can't be done with moons though.
