Hi Rolando or anyone who can help... I'm hoping to get the exact diameter and thread specs on the RA rear cap for a 900GTO. I want to get a custom one made that will allow me to permanently keep the polar scope in place while covering/protecting the RA bearings... So, essentially the same cover as the stock one but a little deeper and with a hole in the middle to allow the polar scope to stick through.



Thx,

Danny

Hi Joe,



I don't know that they do need that much protection. It's more of an aesthetic thing for me because I'm shallow and vain like that. :)



Since my setup is completely mobile, any little steps I can get rid of (like threading and unthreading the polar scope) are appreciated. Getting something to cover everything is another idea, too.



Best,

Danny

Danny,



Short term McGuiver solution - pint sized (flat end conic) yogurt tub,

with two elastic ears (bungee elastic bands), looped over the AP-900

elevation tightening knobs. Actually, the white tub and black bands, even

fit the Astro Physics colour scheme quite nicely, while they protect both

the threads and the PAS. :-)



Cheers,

Joe

Just buy an extra cap and have a machinist machine a hole in it to allow

your polar scope to go thru the hole.

Hi Danny and group,







The threads are 3.590" x 24 tpi. If you have something machined, I

would certainly take the existing cap to the machinist for him to

measure and inspect. I have posted a picture package of some shots

that Frank Barnes sent me of his very excellent cover in the Files

section. It has the regrettably unoriginal name of

Picture-Package.jpg, because I forgot to rename it first.

Unfortunately, I don't believe the guy who actually machined the cover

is still in business, but for that rather interesting story, you'll have

to talk to Frank, maybe at AIC!



This cover would have a rather limited latitude range, especially with

older mounts that do not have the taller polar forks. Those of you at

higher latitudes would be out of luck. (No, I don't have a precise

latitude range!) We have thought about making them, or something

similar, but couldn't quite get them to the top of the priority list.

This might be a good chance to see what kind of demand there actually

is.

Hi Roland,

Then, thread the hole and screw on a plastic or metal pipe with a cap on it to encompass the head of the polar scope!

Thanks, Rick

Hi, Howard:



I'll take two: one for the 900GTO, and one for the 1200GTO.

Hi Howard,



Thanks very much for the specs.



As far as that cap, that's exactly what I'm looking for. The mount in the photo appears to be an older model as my PAS has an AP collar on it that makes it stick out further from the back than the one in the photo. So, assuming the cap would accommodate it, you can put me on that list if you're putting one together. I'll look into having one made in the meantime.



Best,

Danny

Hi Howard,



I also would like to be placed on the list for a rear cap for my new 900. It is so convenient to keep the polar scope in place and protected. Takahashi, Vixen and others offer this on their respective mounts and the rear cap is a very nice addition.



Thanks to you and Rolando for consideration.
