Right ascesion slow motion control knob loose, does not work

Hi, first time used my telescope in couple years, watching Jupiter, keeping in center with dec. slow motion knob and found RA ascension slow motion knob loose, just spinning, no movement from the scope what so ever , RA was not locked, tried in partially lock, no change. When I manually turn scope, the knob will spin some, I'm not sure if the screw in the knob is just loose, but where to you get a tool to tighten it? Any ideas?? thanks Amy

Right ascesion slow motion control knob loose, does not work

The RA knob has a setscrew that fixes it to the shaft. Just need to find the correct size and tighten.

Telescope broken hi. i recently started using my meade DS-2000 series telescope that i bought 4 years ago. it was working fine except that the motor would not move the telescope vertically. i took it apart to see if i could fix it like most of my toys that don't work, but it looks like some pieces that are supposed to be welded together aren't, and a plastic gear is loose on a metal piece meant to be welded to the part that hooks onto the telescope. i couldn't find a replacement part, on the internet, so if you have any suggestions, please let me know.

You will not find parts for these telescopes-- however Meade can repair them if you send them in.Meade does not sell parts for their telescopes --

Can't focus my telescope

If there is nothing on the objective lenses or eyepiece lenses then it most likely needs collimation. This is where you adjust the secondary mirror while viewing an out of focus star. You need stable sky conditions to do this.There are most likely three small screws at the front of the telescope and these are what you use to adjust it. As one screw is loosened then another is tightened. Do this in very small increments. If you have your manual it should outline how to perform this. If not go to this web site: It will show examples of how objects look both in and out of collimation. There is a section further down the page for SCTs.A very handy tool for this is to replace your screws with Bob's Knobs ( . These replace the screws and allow you to adjust it by hand instead of a screwdriver.The other focusing problem I've experience with my Celestron SCT is to have the focus knob loosen up and then slip as I turned it so that I could never focus with it.Good luck and clear skies!-jodair

Focusing Issue Last night, I used my Celestron 11" NexStar11GPS for observing and astrophotography, and it worked like a charm. Tonight, with the same equipment, I am unable to focus the telescope at all. I turned both the coarse and fine focus knobs counterclockwise as far as they will go, but every object is still out of focus--and once I reach a certain point in turning the focus knobs, the object simply moves in the eyepiece rather than becoming more focused. This problem is present with or without the use of a diagonal. The only thing I did with the telescope between last night and tonight was to mount a Celestron StarPointer (a holographic sight-type finderscope) onto the side of the telescope tube's back end with some 8x32 3/8" screws using pre-drilled screw holes. What happened?

The screws should be short enough not to stop the primary's travel, but pull them out and try it again. Good luck! George.

The teeth small pinion gear on the focus knob shaft are stipped

No. That's one of the trade-offs with cheap models, they can be fine but have absolutely no spares back up.All you can do is to check whether the 'scope is covered by a manufacturer's warranty.

Meade LX200GPS Not powering up for batteries

Fork mount on side of R.A. slow-motion control is coming loose from base. This is not the side that contains the Dec. slow-motion control. There appear to be 3 plastic pegs protruding from the fork into the base. It appears that there must be some means of securing these inside the drive base. This is not visible by simply removing the metal base plate. It might be possible to see this area by removing the plastic plate on which the batteries and motor are mounted. It looks like there is just one hex nut in the middle that needs to be removed, but I am apprehensive that I might damage the motor drive. Thank you for your assistance. Leonard Ellis

The drive motor will not be damaged as long as it is not being pried or pulled on. There should be a nut or a threaded cone to hold the pegs in place. It may be stripped or just need to be tightened.
