Re: GTO CP3 Problem

pepineus
 

Hi there,

After considering all the options I was offered, I concluded I could not justify the cost of sending my CP3 unit to AP to have the upper serial port repaired and have to deal with customs, etc, or purchasing a brand new CP4. Instead I found a good working condition CP2. My workflow is actually very simple, and when in the future I may require a much more sofisticaded mount, I will seriously consider a new one with all the bells & whistles.

I am happy with how the mount performs with the CP2.

I wanted to close this thread I left while trying to solve my problem, but in the spirit of trying to help, I found this: lots of "Communications Errors" between the control unit and the driver. This led me to substitute all hardware (cable, serial plugs, I even had the Keyspain serial/UBS reinstalled). My PC runs on W10 and is up to date. The driver I was using was Ray's last one. The "Communication Errors" did disappear when installing back the 5.09.01 driver (not that I tested all of them in between that one and the last one). But this is how I sar the "Communication Errors" disspear.

Thanks everyone for the assistance, my problem solved in an unexpected way, but I am happy I can enjoy the mount again.

Re: Clutch Plug Removal on AP 900

Thanks for sharing your experience Robert.
I have yet to need to change my 2009 AP900 GOTO clutch plugs. Both axis move freely when the clutches are loosened. I am conservative on how much I tighten my clutches. I only tighten them using the short end(tightened as much as I can using my fingers)of the allen wrench. I make sure my scope-camera rig is well balanced in the saddle and the counterweights are properly positioned so that excessive tightening is not required.

Ray Gralak has a tutorial for downloading the information on Youtube.  https://www.youtube.com/watch?v=0Mvp0COjEIg  I did it the other night for the same purpose and it worked well.  I still have challenges processing the comet subs in Pixinsight.  It looks like it should be straight forward but hasn't shown to be.

Re: Custom Tracking Rates

 

Hi Brett

As a slight aside, if you are imaging the comet, most of my friends who are doing that are using standard sidereal tracking and then handling the integration of the stars and the comet in processing (PixInsight has a comet integration capability which looks pretty straightforward). If you use comet tracking your comet will be fine but your stars will be blurred out.

Re: Mach1 Unable to Find Home Position Suddenly

The CP3 is bone dry, nothing wrong there. On another positive note, the mount tracked well all night again as far as I can tell and had parked itself spot on. This is the second night in a row. The start was as bad as the other night (below right and remember that the correct position is close to Meridian) and it's almost like the initialization goes wrong somehow (or doesn't always happen) but I don't know how to verify this. Only after I power off everything including the SGP things seem to improve and when I do a trial slew and it comes back close enough (that same 1/4" typically) I know that if I start the sequence, it probably will plate solve and do it's thing. That's what happened yesterday also.

The photo on the left taken during the daylight was one when the mount was supposed to park itself from 3 to 4. Not pretty...

No keypad, nor did I have a small enough Allen wrench to check the small worm gear screw. But I used a marker to mark it and the axle to see if they have moved after a slew or two. No movement and as said, I don't think this is a mechanical issue. As a a matter of fact, I'm starting to see similar issues when the control panel had moist in it and when the mount started slowly to slew and suddenly speeds up. This happen twice now tonight for the first time. Also and I don't know if I have been able to confuse the whole thing but after playing with the mount now for awhile and asking it to park 4, it will hit the pier. That's how much off it is now.
