    Red face Regarding Japanese Prinz Astral 400...



    Hello.
    I have a question regarding this telescope. It will become clear that my understanding is really limited, but I hope someone will help me regardless.

    I recently found a Prinz Astral 400 in a charity shop and I wanted to get to understand how it works and then begin exploring the night sky.

    However, i realised that i could not see a thing.

    After some research online I deiscovered that it should have another lens, inside the tube. I took the telescope apart and discovered a hole near the base, where the eyepiece is, and no lens.
    I cant get to the hole to measure and fit a new lens.

    can anyone help me?

    thanks in advance for your time.

    I feel it's a great shame that this post wasn't answered. I know it's too late for Bingo, but for anybody else who picks up this thread, this is a good quality Japanese optics scope. It does NOT have another lens in the tube. I can't be certain why Bingo couldn't see anything, and I'm guessing what he meant was that he couldn't bring anything to focus. The chances are that he was using it without a diagonal, which might have accounted for it, also he may have been trying to use too short a focal length eyepiece and just couldn't find a star! As most of us know, if you have a short focus eyepiece in and it's way out of focus, you might have a star pass through your line of sight and miss it. Always use the longest (i.e. biggest number) eyepiece first. Again, if you set the scope up on a distant land object during the day, you'll have a much better chance of finding a star when you go out at night. It will still need further focusing, but it won't be too far out.
    Cheers
