Fitting Right Ascension Encoder Housing
If the encoders were purchased with the 1200 mount, it is likely that the right ascension axis adapter and encoder housing
have already been installed. Please continue to read these directions since you may need to remove and reinstall the
encoders if you use a polar alignment scope. Since the polar axis telescope and R.A. axis adapter thread into the same
location, you will need to switch back and forth between them as needed. If you use the JMI NGC MAX or Mini MAX Digital
Setting Circles, you can use the "polar align" mode in these units instead of a polar alignment scope!.
1. If the encoders were purchased separately, the silver-colored R.A. axis adapter may be inside the R.A. axis
encoder housing. If it is, remove it now.
2. Thread the R.A. axis adapter into the end of your R.A. axis (if your polar alignment scope is fitted you must
remove this first along with the polar alignment scope adapter). Use moderate hand pressure to tighten the R.A.
adapter since you may need to remove it to install the polar axis telescope at a later time.
3. If you look into the black encoder housing, you will see the encoder itself mounted at the rear of the housing.
When this installation procedure is complete, the encoder shaft will insert into the center hole of the R.A. axis
adapter. This allows the encoder to read the motion of the R.A. shaft as the right ascension axis moves.
4. Now thread the R.A. encoder housing onto the R.A. axis housing. You may need to wiggle the encoder housing
gently to engage the shaft of the encoder (located within the R.A. axis housing) with the hole in the center of the
R.A. axis adapter. Again, use moderate hand pressure as you may wish to remove this at some time.
5. The hardware for your encoders is now installed. For actual set-up procedures for Micro MAX, Mini MAX or NGC
MAX, digital readouts refer to the relevant operating manual from the manufacturer. We provide some startup tips
in our instruction sheet entitled “Using JMI Setting Circles”.
Periodic Maintenance
If you remove the R.A. encoder frequently, you may wish to use a very tiny amount of auto grease on the mating threads.
