Suggested Questions And Answer :

I have a makusutove 150 1800 telescope and I cant seem to get it to focus correctly - it seems as though the mirrors are focussing the light behind the viewing lens. I can get a focussed image if I hold the viewing lens about 4 inches behind the telescope. how can I adjust this telescope to enable a focused image with the viewing lens in the holder?

You do not have enough BACK-FOCUS, you need an extension tube for the focuser like this one: the correct size for the focuser hole--

I cant get an image or focus - Bushnell NorthStar 78-8830 (525 x 76mm) Telescope

Put the eyepiece with the largest number written on it into the focuser. DO NOT USE the 2 x barlow if you have one. Go outside during the day time and practice focusing on a distant object, by turning the knob on the focuser in both directions until you see a sharp image.

Luminova 40114675 (675 x 114mm) Telescope: cant veiw anything out of it...

This is a REFLECTOR style telescope. The end with the focuser and the eyepiece is pointed UP. the mirror is on the bottom of the scope.Take the scope outside during the daytime and practice focusing on a distant object using the eyepiece with the LARGEST number written on it.The PICTURE shown above really makes me laugh. The scope is mounted BACKWARDS in the picture above, and is pointed toward the GROUND not the sky. Even FIXYA puts them on the mount backwards!Look at this picture. See how the eyepiece and focuser are on the end pointed toward the sky. The MIRROR is the BOTTOM of the telescope: believe your scope is mounted backwards just like the picture FIXYA applied to your question!

I've just purchased a used TAL 1 telescope complete with eyepieces and Barlow lens. However I can only get objects into focus by moving the focuser to it's limit and then physically lifting the eyepieces part-way out of the eyepiece holder. I don't think this is a collimating problem and my searches on the internet turned up a possible cure - a focuser extension tube (11/4"). Your assistance will be appreciated.

Yes, the "back focus" is too short. That extension should work.
