    I know there are a few amateur astronomers here, eh @ARMANDII ?

    I've been given a telescope. The former owner doesn't know if it's bust. She was having a clear out of her grown up son's room. The telescope hadn't been used for years.

    When I look in the viewfinder, I see massively magnified view around a circle, but my own eyes looking back at me in the centre of the circle.

    Is it bust or is it a calibration issue?

      It looks mostly like the middle pic.

      Okay, then one end should be closed and the other end should have what is called a Spider to which is attached, on the inside of the Telescope tube, a small mirror facing down towards the end of the tube. Also the position for the eyepiece should be at the top end of the front of the tube. Does that compare with your scope?:scratch::snorky:

      Oh, and is it mounted on a tripod or is it just the scope...........and does it have a brand/model name on it.??

      It has one of them but, having just looked at it again, I can poke my finger straight into it, so clearly it is missing something.

        Okay, so the scope has the eyepiece position but it has no eyepiece in it, and you can poke your finger into it..........but don't!!:nonofinger::snork: So there's a very good chance of the scope being a runner and able to work.:hapydancsmil: However, there are a few things you should know about a Newtonian type. Firstly, they have two mirrors,
        upload_2016-8-29_21-18-51.jpeg
        the primary mirror is at the bottom of the tube and the light goes into the front end of the tube to the primary mirror and then back up the tube to the second, smaller, mirror which reflects that light up through the eyepiece position up into the eyepiece and thence into your eye. Those mirrors will need aligning [called collimating] to give a sharp image into the eye and you will have to learn how to do that.......it's fairly easy.
        Have you found a brand name or model name and is it on a tripod.??

        Brand name is Tasco. It also says on it D 76, F 300.

        Edit. Yes there's a tripod with it. The tripod is bust but I reckon I can fix that.

        Okay, I think this is it
        [​IMG]
        They come in different colours of course. Anyway, there's good news and bad news. Tasco's is not known for quality scopes but having read a few reviews a lot of astronomers have fond views of them as beginners scopes. Here's a proposal if you send me your address, via pm, I'll send you a Meade 26mm 1.25 inch eye piece to fit your scope. The eyepiece is a spare and I rarely use it anymore.:coffee::snorky: Sorry for the delay in replying but I've got rare clear skies tonight and I've trying to get the actual GOTO Mount on the scope accurately aligned with the Polaris Star [True North] which I can't see from my Observatory. I've been using a method called Drift alignment and I think that, tonight, I've near enough "cracked" it.
