There is an adjustment screw on the focuser, turn it a little to tighten it up.

If this does not work you have two choices- send it back to Celestron to get it repaired,or call them for a replacement focuser.

Some folks might try to open up the focuser to see what is wrong, but I would just send it back before I did this. This is a high end refractor and a high dollar two speed focuser.

Try the thumb screw to tighten it up first before you send it back.

Why


If you turn the mixer upside down, you will be able to see a locing screw which holds the hinge pin in place.

Center the pin and tighten the screw.

Focus knob turns but nothing moves


The Celestron manual for this scope has nothing to say, but on the underside of the focuser assembly, between the 2 focus knobs, you may see 2 screws.
They might be thumbscrews or some other screwhead type. One is the adjustment for the focuser internal clearance, or looseness, and the other is a focus travel lock.
If present, try backing both off 1/2 turn from tightness, and then experiment to see which is which. The focus lock will have no effect until tight, when the focuser will cease moving, as is now. The other screw will gradually remove looseness and rattle from the focuser until it just moves smoothly, with no back and forth loose feeling at the knob.
If neither of these screws is visible you will have to take it to a binocular and telescope shop, where they should not charge much.

I have recently moved my Sony 57" projection tv and the image is now blurry. I have tried adjusting the convergence manually but I'm no longer able to line up the crosses.


Adjust focus block, then adjust each of 3 lenses. loosen w/ thumbscrew, then turn cylinder to focus onto screen. Focus each by covering the others w/ typing paper, then tighten.

Horizontal lines, they can go away for awhile if we move the TV, but they come back. Most annoying. Can't figure out if there is such a thing as a "horizontal hold" button on this thing, but I...


Hello

If your TV has nice thread like horizontal lines on the entire screen, at aboug 1 inch apart or so, it is due to the high screen voltage. In some sets, this voltage may go high due to a defect in screen control adjust preset, integrated to line output transformer [LOT].
You just open your tv and locate the screen adjust control. It can be seen on the above said LOT itself. There will be two adjustable controls, one for adjusting focus voltage, and the other for adjusting the screen voltage.
Dont touch the focus adjuster. The screen adjuster will be at the bottom of the focus control, and both of them have visual markings there stating 'Focus' and 'Screen'.
Just turn the screen adjust control a little, while looking the picture on the screen, and adjust it till the lines on your screen just disappears. Never turn more than this position. The turning must be counterclokwise, not clokwise, as this should shut of your TV.
Take every precautions when we works with an elelctrical equipment. As high as 25,000VDC points are there, while tv is working, you should be very cautious. Do this with confidence. Take care. OK.

Can you tell me the order in which each componet of a gas furnace comes on to start the furance?


Yes there is a sequence:
0:00 Dial for fan/limit switch is at 70 deg position. Furnace is cold. I turn T-stat to 80 deg to start furnace.
1:00 Burner comes on and dial begins to move slowly up.
2:30 Dial at 140 deg and fan motor comes on. Dial never goes above 150 deg.
3:00 Burner turns off. Dial slowly moves back towards 90 deg.
4:45 Burner turns on and dial is at 110 deg.
4:50 Fan turns off with dial still at 110 deg.
5:30 Burner off. Dial at 120 deg.
6:15 Fan on. Dial at 140 deg. Burner is still off.
7:00 Burner on. Dial at 120 deg.
7:40 Burner off. Dial still at 120 deg.
8:30 Fan off with dial at 110 deg., and it quickly snaps back to the 80 deg. position.
8:30 plus, cycle continues.....
