AP1100 Dec End Plate

Phillip H Coker <pcoker36@...>
 

Removed the end plate to feed control wires through the mount. Now cannot get the end plate to go back on. Removed the safety knobs to make sure that the brass pins were not in the way. That didn't help so I set the Plate out on the driveway in the sun until it heated up to probably 125F but that didn't help either. That plate slipped off easily with no binding but I cannot get it back on. What is the secret??

If you use the provided 22.1mm spacer, the min length is the same. If you dont use it, the min length of the flattener adapter will be 2.6mm longer. (20.9mm vs 18.3mm).

I agree. Precise Parts can build adapters for just about any combination. They do have limits on the minimum length for some adapters.

What’s the diameter and thread pitch of the filter wheel you have? If from ZWO, I suspect metric, you could use one of the spacing rings from Baader such as this for M68: https://www.baader-planetarium.com/en/accessories/adapters-imaging-accessories/m68-zeiss/baader-m68-varilock-15-20mm-extension.html
Baader also have these for M54 and M42 I believe. And they also sell AP to metric adapters for your flattener. 

Precise parts will certainly make you a very good part but the Baader route is also available and likely cheaper, especially if you are not in the US (I don’t know where you are). 

Or you could machine an adapter if you have access to a lathe?

Precise Parts is the best route.

Hello All,

I'm currently using the AP Nose piece adapter for CCD field flatteners and telecompressor (part #ADATCC2) to attach my ZWOASI6200MM camera. The AP Nose Piece adapter makes is very difficult to adjust the telecompressors 1mm spacing allowance. The three compression screws on the adapter can easily create tilt issues plus sliding the camera/filter wheel in out with any accuracy is difficult to say the least. Does anyone know if there is an accurate threaded spacer option available to match the AP field flattener and quad telecompressor to the ZWOASI6200MM&FilterWheel?

Thanks in advance.

Don't use Autostart YES until you get it to first work with Resume from Present Position and Autostart NO. Once it works and points correctly you can switch to YES and it will start automatically from any position that you left the scope in, even if you left it pointing to China.

Remember also that your time, date and location must be correct in the keypad. If your first slew is off by 45 degrees it is most likely that one of these is wrong, probably the time, daylight savings etc.

Hi Ray
I've done the update and can connect to mount.  I have changed to Aotoconnect=Yes from the keypad.  There a couple clear nights here in MI so hopefully I can get this ironed out.

Thanks Peter & everyone for the help.  Once I get the observatory straight it will be great to flip a switch and go.

Re: Mach1 and GTOCP4 Yellow Light

Roland Christen
 

Sorry, I had assumed that the mount was operated in the condition we received it, which was with the lever in the half way position. There was a lot of wear on the gearwheel and that could be one way that this happens. Another way would be if the tops of the teeth were allowed to ratchet past each other if you happened to unlock the lever in a place other than Park3 position. Again i caution to set the back stop gently if and when you feel the need to adjust it. For RA you should never have to adjust it, and rarely ever for Dec. The backstop has zero effect on backlash in either case.

We did clean and completely overhaul your mount, checked the PE to be smooth and under 7 arc sec P-P, re-greased your gears and tested everything twice before sending it out. My caution is simply that, please make adjustments carefully and gently if you feel the need to adjust something. The mount should be ready to go without any adjustment as is.

Rolando I find your comment disappointing assuming that I have done something like this. I have never left the lever to any other position than fully engaged. As a matter of fact I don't touch my mount, it just stays put and as you might remember, these latest problems started as an electrical issue (connection) when again, nothing had changed. The only time I have adjusted the backstop was months ago when I had the weird plate solving problem. After that the mount worked for months before this latest issue occurred.

I replaced my Mach1 with a 1200 and have not really had any problems. I sync with SGP by centering a star selected with coordinates. My mount did get "lost" after I did some adjustments using the hand controller. I released the clutches, put it back in park 5, reinitialized, and all is ok. Goto's are very accurate.

Re: 1200GTO Pointing Issues

Unpark from Present Position is more accurate.
In fact if you are permanently set up, put the keypad in Autoconnect YES and your unparking will be automatic and more accurate.

Hi All
I'm setting up my observatory with all the software.  My 1200GTO mount with CP4 is having pointing issues.  I saw that it was recommended that I select Unpark from position 4.  I tried that with no difference.  Is my keypad database corrupt?  Should I reload my database?

Thanks

Hi Ray
I tried unparking from APCC.  When I chose unpark from position 4 I got a warning asking if I was sure sure about unparking from 4 because I risk running I to pier.  I hit OK then resume from last park went into window and greyed out.  I'll check my version.

Am I supposed to put the mount in park 3 when I select resume from park 3?  I normally use position 4.
Thanks

Re: 1200GTO Pointing Issues

Hi Carl,

Are you unparking from the AP hand controller or the driver/APCC? If you are planning to use Windows software, you should unpark via the driver/APCC.

Also, try unparking from Park 3 instead of Park 4. Park 3 has the scope pointing at the celestial pole and counterweight shaft pointing directly to the ground. If you are using APCC then power cycle the mount and let APCC initialize the mount.

BTW, the latest APCC Pro version is 1.8.4.1. The link is here:

Hope you get this resolved quick, looking forward to see some images from you again. As for the problem, is all the mount/keypad firmware up to date?

Hi Bryan
I'm guessing maybe 45 degrees or so to the East, nowhere near close.  Checked my timezone, set at 5(Eastern time).  I never could get mount to find a star past transit, but only stopped trying at 12:30 am.

Yes the error is repeating.   When I go to park 4 the ra looks to be in park 2 with counterweights down and dec correct.

When I synch, I use TheSky, the mount looks to be over correct object but when I slew ota always goes to west side of mount. If I try to use keypad to synch I get error in APCC about target error too far in ra to synch.

Thanks

Please provide more info about 'pointing issues'.

For example,
How much is pointing off on the first star?
Does the error change after a sync?
Is the error repeatable?

It is difficult to diagnose 'issues'.
