Thanks Geett,

That is what I was suggesting as well - but I am glad you found a perfect
fit. I will go out and buy "a dozen eggs" with 4 spares if I lose a cap. Did
you find one for the DEC axle tightening knob?

One question: is there any problem putting them on in the cold, if you
have to remove and later put them on again? The plastic OTA cap on my 4"
Bausch & Lomb will not go on after a night of observing in winter - I have
warm up the OTA cover first.

Hello,



I came up with this solution for the clutch knobs:

Hi Dean,

I had a look at your AP2.jpg close-up, and I think this knob, as well as
others, can definitely use some "cosmetic streamlining"-. I don't like the
idea
of making the cables even thicker by encasing them in flume(?), they are
plenty thick enough.

What if some kind of cap could be made, that would fit over the knobs, but
can be removed if they needed adjustment. Most of the time, once the mount
is
set up, these knobs no longer need attention. How often do you adjust the
latitude knob, for example - yet it is there to cause potential cable grief.

As a test, I propose you use a wide piece of cello tape - like "shipping
tape" - and spread it horizontally across the DEC knob (you could brace the
cello bridge on each side, with a piece of shipping foam peanut, to give
some
lateral support). Now do the test, and watch if the standard AP unsheathed
cable still snags on that knob. I expect it will merely "ride over it".

If that works each time, then either use tape over the problem knobs -
which can be done for permanent setups - or somebody should devise a more
solid bridging device. Something that comes to mind is a plastic strap, like

that use in a recent product for "opening the nasal passages" for suffers
trying to sleep with nasal conjestion. That kind of bridging strip, if it
can
be held in place on top of the knob, would act as a "cable deflector".

I hope I have explained this clearly.

Joe
