Hi I have been having random slew problems. Everything is working fine then suddenly both the motors go off at max speed until I either pull the power or get...
First thing to check in the cold is whether your power supply is still putting out the proper voltage and amperage UNDER LOAD. Batteries will lose the ability ...
Hi Jerry thanks for the reply. The power is good (i think) - its running from the mains with a regulated DC converter. Any tips on how to keep the connectors...
Hi Jerry, Hi Ice70, Each motor unit is sealed by the use of 4 corner screws. The heads are Philips but are very small and may be very tight as well. Remove the...
Use a voltmeter to check the voltage coming out of the connector. Meade uses center positive and you should have at least 12V. I have heard of wierd things...
OOPS! I forgot to add, check the voltage both when it is cold and warm. If you can, check the amperage draw under load both warm and cold also. If there is a ...
Hi Jerry, Glad I could help out..for such little units they are quite powerful with the included gear assy.By the way where do you live in AZ..I have a...
Tom, I live about 20 miles south of Bullhead City in Fort Mohave. I love the desert and even the 130 degree temps but it is getting a little crowded in this...
Hi I have cleaned the whole motor assembly unit with isopropyl alcohol (except for the gears) and then ran the motors and had the same problem - it seems to be...
... Yes. The unterminated (due to lack of Autostar) signal lines pick up electronic noise and the motor cards try to interpret them as commands. Havoc...
Has anyone got any info on how to adapt the 8 pin HBX port on the motor drive to connect with the 4 pin on the #506 cable to run the scope with starynight....
For future reference there are phots of the drive in Photos (surprise!). One here: http://tech.ph.groups.yahoo.com/group/Meade4504Telescopes/photos/browse/\ ...
Dick, Question from ignorance: Why does anyone still use electrolytics? Is there something they bring to party that other types of caps can't? They seem to...
Tantalum capacitors have a smaller physical size. From my computer experience and training where motors, relays, etc. needed some electronic impulse...
Addendum to previous reply: I neglected to state that a lerge electrolytic is NOT desired. They do not respond fast, and arc then short or open internally. A...
Electrolytics are low voltage with this insulation separating the 'plates'. And contain an electrolyte and age poorly. They don't like large swings in...
My proofreader is on strike. ================== Electrolytics are low voltage with THIN insulation separating the 'plates'. And contain an electrolyte and age...
... What electrolytics (of any form) bring to the party is the highest amount of energy storage (capacitance) in the smallest package at a reasonable price. As...
i just bought a meade 4504. and was thinking of getting a imager and was wondering how do imagers work. do thay just slip in to the focuser. and do thay need...
If you buy a purpose built imager like the Meade then it fits into the 1.25 focusser. It usually says what kind of eyepiece it acts like. I think the B/W...
thanks that helps alot. i already bought a 1.25 focuser for the 4504 so now i know that a good imager will work with out a eyepiece. that will be my next buy. ...

With a cheap webcam you can play with the Moon and planets a bit and get a feel for what's involved. The Phillips ToUCams are the best, but before you spend...
With the webcam's lens removed you are using it in prime focus. In this mode the telescope's focuser is used. As the imager in only about a 1/4" inside the cam...
Has anyone had the plastic housing of the drive gears crack and break? Is there a parts site available to replace them? Thanks for any info. Walt ... Never...
i just bought a used 4504 and when i got it it can with 1 extra gear housing so i know some one some were sells it you might call up meade and see they should...
I've a crack on the gear housing too ... the result of overzealous tightening of the retaining bolts. I'm thinking of using some epoxy on it. Might put a layer...
