I really like the amount of detail that can be seen in the Bok globules/dark nebula considering I was using a 4” refractor.

Oh yeah, you’re missing out on all the “fun” of portable observing – which includes sore muscles, barked knees and elbows, dust, insect bites, wild animals, dust, cold – and did I mention dust?

I was referring to the idea of putting the shaft end cap onto the mount for storage.


Re: Counterweight Shaft Case

Brian,
 
    Everyone should also check that they have THAT special AP-provided  TEFLON washer/disk, on the threaded end of the shaft. Otherwise, you may find the steel seized  into the mount axis, very difficult to remove, especially in the cold. Don’t lose it.
The Teflon really helps, and now I wouldn’t attach the shaft without it.

Your design looks like it also has a 'homing device'...so, if you leave the shaft and case at a site, it can be returned to you!  Brilliant!

Here’s my awesome counterweight shaft transport case.  This is for an AP1200 CW shaft, but I also have a very similar one for the shorter AP1100 shaft.

The case you see here is specially designed to prevent rolling around in the vehicle, and has been reinforced in the appropriate areas of the structure.  

This has served me very very well since 2005 and has been to many star parties, public programs , and countless imaging sessions.  

I give it 4 stars rating… knocking off a star as the cover needs minor work with some gaffers tape.

Barry – Yes and the recommendation was to screw it into the RA assembly.

Which I did so one last item to worry about.

So I think everyone is in sync now.  And I never thought about that.  And the fear was I’m 200miles from home and leaving those small items behind – been there and done that.

I believe the question was about the safety stop that screws into the end of the shaft, and that is small and I keep it with other accessories.  The case does have a screw-on PVC pipe cap that seals the shaft inside.

Hi Jack,

No one mentioned it here, but I screw the counterweight end cap into the end of the RA axis where the counterweight shaft screws into. :)

Re: How Good Can Guiding be With Non-AE Mount

Nick Iversen
 

I did exactly what Rolando said. My mount is 3 years old. This is what I got. There is a definite periodic error. I used PemProV3 to fix the error. PemPro was surprisingly easy to use (and free for 60 days). And it worked. Not only did it remove the error but it reduced my PHD2 RMS from about 0.5" to 0.4". Nice!

One more tidbit – Joe

 

3M has the glow in the dark tape – so if you inadvertently drop it, it could be quite noticeable.

Hi Barry,

 

    Guess I missed it – I assumed you had cemented-on a “threaded ABS fitting”,  which would conveniently accommodate a threaded end-cap, so no need of the cap being stored in a case,  or falling off the pipe in the trunk, possibly lost on the ground at night.

Wouldn’t want to risk toe-injury if you held it upright, the wrong end  up, and the cap is slammed off downward by the heavy bar :-)
