Backlash in the R. A or DEC gear is caused by two things. First, the meshing of the worm to worm gear and second if there is play of the worm between the two worm bearing blocks. To take out the two causes of backlash, first remove the cover over the motor. Take out the two screws that hold the motor to the mount. Loosen and remove the two set screws located under the panel that covers the worm.
Locate the worm bearing blocks and loosen the screw that is behind the bearing block that is furthest from the motor. Sandwich the two blocks between your fingers and pivot the worm into the worm gear slightly. Tighten the screw and try to rotate the worm in both directions. The worm should rotate freely.
Grab hold of the DEC housing or the saddle plate depending on which axis you working on. Check to feel for any play. Repeat this operation until the backlash is removed. Motor sounds like its running but the mount is not tracking. The motors on the mount are of a type called stepper. This means that the motors move in a precise angular step for every electric pulse and may create a barely audible noise with every step. The connector on the motor needs to be replaced. Clutches can not be tightened, Clutches skip then grab, when moving, Axes do not move freely.
After years of use the clutch paddles and bearings need to be cleaned and lubricated. To do this, you must take apart the mount slightly. Both R. First, remove the clutch knob. Five parts will come off the shaft. Spring washer, aluminum spacer, thin washer, needle bearing and thin washer. Second, grab hold of the DEC housing or saddle plate depending on which axis you are working. Pull the axis straight out. At the end of the shaft you will find a nylon disc.
Remove this piece and clean both sides with rubbing isopropyl alcohol. Clean the aluminum plate and shaft where the nylon disc rests. Clean the aluminum plate that is left on the mount. Look down the hole where the shaft fits you will see two needle bearings.
One on top and one in the back of the mount. With your finger, see if you can turn the bearings easily. If not, apply WD to the bearing and work them free. Once they can turn freely clean them with alcohol, then apply standard grease to the bearing. You will want to clean and grease the thrust bearing back by the clutch knob.
Make sure not to get grease on the clutch area. Assemble the axis back together. Apply some grease on the threaded part of the shaft were the clutch knob screws.
Analog setting circles lose calibration. When you use the quicker setting rates on the drive, the setting circle and the pointer move together. If you hold the button down for long periods of time or do many small movements, and then manually move the telescope back to the object, over time the setting circles may lose calibration and must be reset.
When I slew the telescope in r. Due to the backlash in the gearbox on the motors, when using the 4x, 8x or 16x setting rate, the motor will have to reverse in one direction. When you release the button, the motor goes back to the tracking rate, but it will take a few seconds to remove the backlash out of the motor. It is equivalent to turning off the drive. This will only happen in one direction, and will not occur in any of the guiding rates.
The pointer move with the setting circles. You can not look at the pointers to see if the drives are working. Look at a fixed point on the mount. After I put on my digital setting circle hardware kit, I cannot lock the clutches. If you are using the Losmandy hardware kit and the clutches will not lock, it is caused by the large gear being too close to the thrust bearing at the rear of the mount. Move the gear back about a distance of two pieces of paper. If you are using a JMI hardware kit, it is because you have the screw at the side of the large gear to tight.
The screw needs to be slightly tight, just enough to keep the gear from rotating but not from sliding along the shaft of the mount. When this happens, it is usually due to inadequate power. The system needs 12 VDC mA or more. If one of the tracking LEDs start to flash, it means that there is not enough power. The amp-hour rating of a battery simply means that it will provide the rated current for that duration of time. For example, if a 12 volt, 6 amp-hour battery is powering a device which draws one amp, the battery will last approximately six hours.
If the device draws mA half an amp the battery will last 12 hours. You can. This allows you to use both, Auto-guider and hand controller at the same time. Yes and no. The ST-4 and ST-5 can be plugged into the same power supply. You must have a different power source, they can NOT be tide together in anyway.
How tight do I need to make the clutches? Clutches are designed so that the operator does not have to loosen a knob to move the telescope. You find the setting that you like and leave it. The clutches will operate with just the slightest tension, though fully locked.
You can not damage the motors or the drive by over tightening the clutches. How do the clutches work? When you tighten up the clutch knobs one knob at the end of each axis it pulls back on that axis. This pulls the pressure plate back against the surface of the gear.
Between the pressure plate and the gear surface is a nylon disc. The more you tighten the clutch knob the harder it is to move the telescope. The tightness of the clutch does not have any effect on how hard the motors must work, but it does have an effect on the tracking of the mount.
If the clutch is left loose, then the mount may slip and not track correctly. You need some pressure on the clutch for proper operation. Weight, Locking Bolt Remove all the parts from their respective boxes and place them on a flat, clear work area. A large floor space is ideal. When setting up your Losmandy G, you must start with the tripod and work from there. To insure proper assembly, each task must be performed in the specific order as defined by these instructions.
There are three possible orientations of the equatorial mount which allow you to select the most convenient location of the electronic console. Once the bar is securely in place you are ready to attach the counterweight s. Attaching the telescope to the mount The telescope attaches to the mount via a dovetail bar bolted to the bottom of the telescope. Installing the polar alignment finder To aid in polar aligning the mount, your Losmandy G accepts an optional Polar Axis Finder which fits directly into the polar axis.
Installing the polar alignment illuminator If you look through the Polar Axis Finder in the daytime the reticle is clearly visible. The Polar Axis Finder is now installed and ready to use. While the above instructions describe a perfect balance arrangement, there should be slight imbalance to ensure the best possible tracking.
When the scope is on the west side of the mount the counterweight should be slightly imbalanced to the counterweight bar side. And when the tube is on the east side of the mount there should be a slight imbalance toward the telescope side. This is done so that the worm gear is pushing against the slight load. When taking astro-photographs, this balance process can be done for the specific aim of the telescope to further optimize tracking accuracy. Like R.
When taking astro-photographs, this balance process should be done for the specific area at which the telescope is pointing. To adjust the mount in azimuth: 1. Locate the azimuth lock screws and adjustment knobs on the back of the mount. After four minutes, the system begins to play back the corrections made during the first four minutes.
When playing back, the LED stays on without blinking. The direction of the drive motor is now reversed and will work in the southern hemisphere. This method can be done in daylight, thus eliminating the need to fumble around in the dark. Although this method does NOT put you directly on the pole, it will limit the number of corrections you will make when tracking an object.
It will also be accurate enough for short exposure prime focus planetary photography a couple of seconds and short exposure piggyback astro-photography a couple of minutes.
Remember, while polar aligning, do NOT move the telescope in R. You do not want to move the telescope itself, but the polar axis. The telescope is used simply to see where the polar axis is pointing. When finished, the mount is accurately polar aligned. As long as the R.
If the drive is ever turned off, then the R. While the R. Once complete, the setting circle should not need to be aligned unless it comes loose. The 2.
