Cable Installation – the First Time

Cables can be inserted either from the top (through

the D

ECLINATION AXIS HUB) or bottom (through the

polar scope end of the RA axis), but the simplest way

will usually be to insert the cables through the S

IGHT

HOLE / CABLE ACCESS COVER on the declination axis.

The easiest trick for inserting the cables, if you will be

routing cables out through the D

ECLINATION AXIS HUB

(as is likely), is to turn the RA axis so the

OUNTERWEIGHT SHAFT ADAPTER is pointing up and

south and let gravity do the work. Always start by

running the cables with the largest connectors first.

Insert the telescope end of the cable into the S

IGHT

HOLE / CABLE ACCESS COVER on the dec axis and

guide it “down” and out the D

ECLINATION AXIS HUB.

Insert the opposite end in the same opening and

guide it either out the RA’s C

ABLE ACCESS COVER or

out the bottom of the RA axis. If you are routing out

the RA’s C

ABLE ACCESS COVER, you can reach in the

bottom of the RA axis to help you guide the cable end

out the access hole.

When all the necessary cables have been run through

the mount, turn the RA axis so that the mount is in its

normal position with the C

OUNTERWEIGHT SHAFT

ADAPTER pointing down and north. Adjust the amount

of each cable that you will need sticking out through the D

ECLINATION AXIS HUB to

adequately reach its electronic device. When determining the length, be sure to

run the cable through the C

ABLE CHANNEL and allow enough slack so that ther

will be no tension on the cable’s plug. Make sure you allow for focuser travel.

Don’t allow too much slack, however, or you will defeat the whole purpose of

hiding the cables inside the mount. Be sure that you route each cable through

the appropriate C

ABLE CHANNEL side for the side of the telescope where it will

plug in. Also, keep in mind any other places where you may wish to tie your

cables like on the end of a mounting plate. Cables f

tied off to the focuser or the very back of the mounting plate.

Once the cables are routed through the mount, and you have the proper amo

sticking out the top of the D

ECLINATION AXIS HUB, you are ready to replace the

ECLINATION HUB PLATE. Be sure that the cables are seated well in the two

ABLE CHANNELS and that they are not being pinched by the plate. Put in two

screws, one each on opposite sides of the plate and snug them down. Re-check

that none of the cables have been pinched and then tighten the two screws firmly. If you are using the FP1800, the RP900 or

the Q4047 (with DOVE08) as your telescope mounting plate, install it now using the four provided screws in the remaining f

holes. If you will be using one of the other telescope mounting plates (FP1500, DOVE15, DOVELM2 or DOVELM162), first

install the remaining four screws from the D

ECLINATION HUB PLATE, and then install the mounting pl

that were provided.

Where the cables emerge (RA C

ABLE ACCESS HOLE or bottom of RA axis), make sure that nothing will be hanging or pulling on

any of the cables. You may wish to bundle the cables together and tie them off to a tripod leg or pier strut to eliminate potential

tripping hazards. Run them carefully to wherever they will be plugged in (laptop, heater controller etc.) and try to avoid creatin

tripping hazards. If you have run the cables out the RA’s C

ABLE ACCESS HOLE, replace the POLAR SCOPE ADAPTER and POLAR

SCOPE CAP. Do NOT over-tighten the POLAR SCOPE ADAPTER. You can also partially close the SIGHT HOLE / CABLE ACCESS COVE

on the dec axis and the C

ABLE ACCESS COVER on the RA axis at this time. They

Disassembly and Subsequent Setups and Polar Alignments

Once you have gone to all this effort, you won’t want to undo everything for relatively simple tear-down and set-up situations.

And you won’t have to! The degree to which you must disassemble the cabling depends on the degree to which you must break

down the mount. If you need to disassemble the mount for airline travel, you will unfortunately need to undo everything. If you

simply move your entire assembly in and out of the garage on its pier or tripod, you will hardly need to take anything apart. Mo

of us are somewhere in between. Disassembly steps are basically the reverse of the installation steps above and really don’t
