Have a older (15year) Meade LX90 with autostar. The coil cable is comming apart as the insulation is going bad. Thought about using a cat5 computer network cable?? Taped up, but needs replaced. Any ideas.

DO NOT use a std cat5 cable.

The Meade handbox cable is wired differently

ie cat 5 is wired 1-1..8-8

Meade is wired 1-8..8-1

I ordered a new one for mine some months ago, if I remember correctly, from AgenaAstro.

OzAndrewJ - if one was to make their own cable using cat 5 wire and ends what would the order be?  Is there a diagram or link you have handy?

 

OP - I have used self-bonding silicon stretch tape to repair similar problems, although it leaves an inflexible end.

 

Would this work?

As per above, if you have cat 5 cable and RJ45 connectors, the wires used are to all intents and purposes irrelevant, you just want it wired 1-8..8-1

Looks correct for use as a 497 Hbx

I got mine from Agena Astro the same as Mitchell's comment - they have 8 in stock at $19 each.

Same thing happened to my ETX125PE cable (about 16 years old). It's easy enough to wire up a new one, but, being lazy and not knowing where my RJ crimper was at the moment, I just ordered one from Agena Astro.

ScopeStuff also has a extra-long (14' extended length) replacement coil cable for the AutoStar II for $21.00.

These are Rj11/12 6P/6C, but the concept is the same for 8P8C RJ-45 cables. You want straight through for most astronomy uses as they are data cable not telephony.
