SOURCE: I lost my manual to my B&L Criterion 4000 5453

Going to be TOUGH to find a manual for that telescope. They stopped making them in the mid-1980s.

You will need a diagonal, eyepiece and a finder scope. The photo tripod is not the greatest for astronomy. Acceptable for the moon and quick views of the planets but with a SCTs narrow view, you will be constantly adjusting the tripod.
I would start with a 25mm plossl eyepiece which would provide 80x power. About as high as you can get with a photo tripod.

Be aware that the Bausch and Lomb telescopes had terrible reputation for bad optics.

I purchased an older Howard Miller clock and the clock is keeping time but pendulum is barely moving. What do I do?


Hi Pam,
I have a Howard Miller Grandfather clock and the pendulum swings very slowly and from far left to far right travels only about three inches at best. It doesn't need to move any more than that to make the "Verge" move the "Escape Wheel" to rotate the gears to keep the hands moving at the correct tick. Howard Miller Grandfather Clock

Hi! I own an 80's model Criterion Dynamax 8 SC telescope which I would like to take apart to install a straight-through Finder Scope. At the same time I'd like to remove the primary mirror and clean it. ...


This is their SCT model-- it comes apart very similar to the pictures in this article:

How do I use the self timer on my Camedia c-4000?


Turn it on.
Press menu button (bottom right beside monitor)
on the Drive menu, press right arrow (on the navigational arrows - top right) to move to selections.
Move down four options - the one with "the little clock (pointing to 11pm) and a radio".
Press o.k. (the button with the green key underneath)
That should now show the clock as the selected option on the drive option.
Press menu one final time to exit.
Camera is now in timer mode until you reset back.

To reset back > press menu - at drive menu - select the top option (looks like a single page image) - press o.k. - press menu

Foggy Objective Lens on


No where at a reasonable cost. The B&L 4000 is being sold for about $200 or so on Astromart.

You can remove the corrector lens and try cleaning it yourself. HOWEVER! it must be replaced in the exact position as it was before you disassembled it. If you rotate the lens by accident you will not be able to collimate the scope. Just make a small mark on the edge of the glass and the edge of the tube so you can line it back up when you put it back together.

There may be some small shims underneath the glass edge. These also must go back in exactly as they came out.

How to stop clock ticking


It isn't that hard to get the clock to stop ticking.

Disconnect power to stove so that you do not get a shock.

Take off back panel screws behind the clock.

disconnect the wires to the clock.

Make sure that the wires are not touching anything metal. If they are not insulated, you will want to tape them.

Do not use the hammer to the dial method to get the clock to stop. It is fast but may cause damage.
