Re: Any special trick to not cross-thread AP1100 counter weight bar during install

Hi guys,

  Thanks for the suggestions! I tried out several of them and found that the suggestions to just remove the black end cover of the DEC assembly and then screw the counterweight bar into it first. I marked where the rod just starts threading in one of the photos of the link.

I also marked the cover and the outside of the DEC assembly where the cover just starts to thread as well. This seems to work quite well.

Very confused with APCC meridian tracking limits

Cheng-Yang Tan
 

Hi guys,

   I spent the entire afternoon setting up the meridian tracking limits in APCC by following the example in the manual. 


   As a test, I chose a star on the east side on the Meridian and then waited to see  what APCC would do when the star goes past the meridian. I found that:


  The "Time before limit reached" box always tells me when the scope will hit the meridian and *not* the meridian tracking limits that I spent the afternoon setting up. And when the time gets to zero, if I had set the action to "Flip scope", it will flip the scope. Huh? I thought it would only flip the scope when the scope hits the boundaries of what I've drawn in the "Meridian Tracking Limits" window.


I must be interpreting what Meridian Tracking Limits mean ... 

Question:

   Should the mount only flip when the scope is at the boundaries of the "Meridian Tracking Limits"?

   Did I mess up setting up the Meridian tracking limits?

Re: Any special trick to not cross-thread AP1100 counter weight bar during install

I just hold it at the same angle as the Dec axis and start it with no issues with the two axes [RA & DEC] assembled together. The issue I always had was taking the CW shaft off and sticking to the CW adapter but when AP introduced the nylon washer it took care of that.

Hi guys,

   I'm having some trouble installing my AP1100 counter weight bar because I am having a hard time squaring up the bar thread to the hole thread. Is there any trick to do it so that I don't cross thread? Grease? 3D printed fixture?

I added a little grease to mine and now each install/removal is quiet.

Instead of removing/installing CW bar, I leave the CW bar in the large black adapter where it connects to bottom of Dec housing and remove/install the black adapter along with CW bar. Much easier threading the black adapter into Dec housing than threading CW bar into black adapter. Plus it makes a very loud squealing sound when threading and unthreading CW bar that will easily wake up the neighbors.

Correct because of the heavy weight of shaft. 
Holding the bar parallel to the ground is a good idea, and in my case I first rotate the DEC assembly up side down, put the thread head of the bar in the DEC counterweight adapter hole with one hand holding the the other side (top) of the bar for the stability for the correct angle, and  start slowly turning it to see if it works.
The good part of this is I can concentrate on the start point of the thread and the angle as the gravity helps the shaft with contact to the adapter.

I recently experienced this too.  Normally I am observatory mounted so I don't need to take the shaft off very often.  But the last time I did I was seriously concerned about it. 

This concerns me a bit because this summer I will be going on a 6 week trip, visiting some very dark sites.  I'll be setting up and tearing down each night and that's a lot of opportunity to strip those threads.  

Thanks for the suggestions here.  I'll see if there is any galling and if some grease will help too.

Re: Problem with PulseGuide Commands Failing to Calibrate Guider

Ray Gralak
 

Hi Wayne,

Great video! I did get it working last night, but there were two settings I had to change that seemed to be
marginally related.
OK, great!

Quick story: pretty hazy but I was able to find a good Star. Updates seemed to fix the Dec out of range error.
A quick note about the APCC 1.7.1.1 update - there were no changes made besides changing the version number from 1.7.0.29 and making it an official release.

Telescope moved but Maxim wasn’t finding the star reliably despite the fact it was obvious. It was making red lines
way out of place from the star. I looked at the auto guide settings in the Options. It was set to multi-star guiding and
32x32 tracking box. BY CHANGING THOSE 2 SETTINGS TO DEFAULTS (single star and 16x16 tracking box) it
worked like a charm. I changed those, it went crazy again. Change back all was great, guiding was super.
Based on what you have written above I think the problem you have been seeing might be an issue with MaximDL's multi-star guiding option. It could be that the multiple stars MaximDL was selecting weren't optimal or maybe insufficient for its algorithm to work correctly. You might try increasing the exposure time to see if that makes a difference.

Best regards,

Re: Any special trick to not cross-thread AP1100 counter weight bar during install

mike.hambrick@...
 

I experienced similar issues with my 1100 mount almost the first time I used it, and for a few minutes I thought I was going to have to call Astro-Physics to order a replacement declination axis end piece. This is not a new concern. Even with my old 800 mount I had to be careful not to cross thread the counterweight shaft. My solution in both situations was to coat the threads on the counterweight shaft with Moly-Cote.

The threads on the stainless steel counterweight shaft tend to gall in the aluminum making it harder to turn. When this happens you can't tell if it is cross threaded or not, and the harder stainless steel will quickly strip out the soft aluminum threads in the end piece. The grease or Moly-cote make it easier to tell the difference between the correct thread engagement and cross threaded. Be careful with grease or Moly-Cote. These lubricants will also greatly reduce the wear on the aluminum threads. Use sparingly though. Both are messy, and you will quickly end up with black fingerprints all over the mount (or worse).

A more permanent fix (or possiblly a repair) might be to put a bronze insert with the female threads for the counterweight shaft into the end cap of the declination axis. There are grades of bronze that are quite hard compared to aluminum, and the tendency to gall is much lower. I expect however that this concept would add quite a lot to the production cost of the mounts.

Re: Any special trick to not cross-thread AP1100 counter weight bar during install

Joe Renzetti <axnyslie@...>
 

I had that problem with my original CW shaft. I needed a longer one anyway so I sold it and upgraded to the newer 16.675" shaft that's machined with a lead-in piece before the threads which eliminates that issue. I always make a mental note to pull it up towards me when facing the mount to thread it on and it threads on smoothly.

My 1100 counterweight shaft has this problem in a big way. I suspect that I am going to have to either chuck it up in my lathe and remove about 1/3" of the existing threads from it, or drill and tap the end of the shaft and add a plug extension to act as a squareness guide.

Re: Any special trick to not cross-thread AP1100 counter weight bar during install

Don’t know if its much help but I like to turn it backwards until the threads “mesh” and then start turning it forward.

Subject: [ap-gto] Any special trick to not cross-thread AP1100 counter weight bar during install

 

 

Hi guys,

   I'm having some trouble installing my AP1100 counter weight bar because I am having a hard time squaring up the bar thread to the hole thread. Is there any trick to do it so that I don't cross thread? Grease? 3D printed fixture?

 

Any advice is appreciated.
