I have just assembled the Tasco 70x 800 refractor, but there does not seem to be any way of adjusting the altitude. There is no knob to loosen the mount, only a nut which is hidden inside the mount which...


There appears to be a KNOB underneath that you loosen or tighten -- and also one on the altitude. Adjust these knobs so that you can move the scope but with some friction---here is the manual

You have NOT lined up the finder scope with the main tube. Point the scope at the moon or a bright star and get the moon or the star into the main tube's eyepiece.

Without moving the scope adjust the screws on the sides of the finder scope and center the crosshairs on the target. Now you can use the finder to line up the main tube.

The finderscope for the Bushnel 78-9930 telescope will not align w/ the telescope. The Azimuth adjustment knob bottoms out before the alignment is achieved. Everything is molded one piece. Besides the...


Obviously the mounting for the finderscope is NOT parallel with the tube-- probably the screw holes were not drilled correctly.

This is one of the reasons why we never recommend Tasco or Bushnell telescopes. They are considered "toy" telescopes and most of them are not suitable for Astronomy.

Return it and buy one of these:

OR re-drill the holes so the finder scope is more parallel with the main tube.

Trying to identify older tasco telescope and put it together


There are only two types of telescopes --- REFRACTORS, and REFLECTORS-

The refractor has a lens on the front of the tube and you insert different eyepieces in the back-- the larger the number written on the eyepiece the LOWER the magnification-- (DO NOT USE THE 2x or 3x barlow which you may have!-- this creates too much power for this small telescope!-- put it away and never use it!)

A reflector has a main mirror on the bottom of the tube, and a small secondary mirror under the eyepiece hole (focuser end) - front end-- put the lowest power eyepiece into the focuser.

Now with either type telescope go out side during the day and practice focusing on a distant object-- turn the knob SLOWLY. At night the moon should be the first target you try.

If you received what appears to be a smaller telescope -- that is the finder scope-- attach it to the top of the tube on the main telescope. Again during the day line up the small finder scope with the main scope-- look at a distant telephone pole (the very top-- and center this in the main telescope. Without moving the main scope use the finder scopes "screws" to adjust the cross hairs so they are pointing exactly where the main scope is pointed. Now you can use the small finder scope to point the telescope in the exact direction--

The moon should be your first night time target.

Good luck--
