    Default Can the moon blind you???



    I was just reading a CN review of the 30" obsession (wow thats a beast) and at the end it said do not look at the moon with this telescope or you will go blind so is it possible to go blind from the moon in bigger scopes???

    I remember reading that exact review. I think a big enough mirror could definitely concentrate a harmful quantity of light to the retina, but blindness? I dont know.

    I agree with mark on this one ....I don't think it would blind you but it would definitely ruin your night vision .....

    Blind? I think it would be dependent on time. Like every young kid looking at a bird or somthing, I've glanced at the sun a few times with no noticeable effects; we all know what would happen if I were to stare at it, though. I think a 30" Obsession could definitely do the trick. My 10" dob is painful enough, I imagine that 30" would do irreversible damage after a night of crater hunting.

    Yea i think so to the time would be probly the greatest factor i remember my brothers friend came over 1 night and i showed him the moon lol it was funny to see his reaction to the brightness

    Also have you look at someones eye when they look at the moon as they move in closer you can see the light getting smaller and going straight into their pupil it looks cool (lol i know random)

    Never look at or near the sun , With a telescope , binoculars or anything else for that matter .....Unless you are using a solar filter or telescope designed for the sun ....

    If I look at the full moon with my astromaster and I have no filter in, it takes me a while to get my night vision back. That’s with a mirror that is only 4.5 inches, so it would probably be even more uncomfortable with a bigger mirror. But I don't think it would blind you. Moon filters are like sunglasses for you telescope, I have two moon filters and sometimes I thread them together and use both.

    Hey Sally , your scope might also have an "off-axis" filter as well ..The scope cover's sometimes has a small hole in it with another cover on the small hole ...If so , try using the scope with just the small cover removed ...It cuts down on the brightness moon as well ....

    Right, I should have included that warning with my post. Of course, I can't imagine any who have been outside in daylight and not glanced up at the sky to get an inadvertent eyeful of burn. Vampires are, of course, disqualified.

    Well, if you can spend $17,000 on a 30" Obsession, I don't think you'll have a problem buying a few moon filters.
