New to me AP1200GTO CP3 V2


Abraham
 

Im going to pick up a used AP1200GTO for my observatory!  Never had AP equipment before. 

1200GTO mount, serial number; 1200802. GTOCP3 serial number: CP3-0874. With the v2 chip.

Im looking for advice on the most updated way to connect this to my computer for planetarium control.  I'll be using a USB hub on the scope. Im thinking my serial to USB adapter can go from the mount to that hub.  

Anyway, 

The original owner said he heavily used it for the first 10 years in his observatory in southern Oregon then not much for the last 5 and none for the last 3.   He stated he never greased it, never had to do anything to it. Works perfectly. So im hoping thats the case.   Im hoping both axis are buttery smooth but am not against greasing it after I get more familiar with it.  

Any tips on these mounts is appreciated.  I plan on dual imaging with this load on it.   Selling my Tak NJP.   My pier is custom and is 8" Sch 40 steel and 5 feet tall , the AP mount comes with a FSA and SPA adapters.  I need to adapt them to the top of my pier.  Maybe even do some welding.  Is this pier up for an AP1200?     About 4K pounds of rebar and concrete in the base.

The USB to serial adapter works just fine.   It is very stable.

The pier looks fine, but you will need to mess with the top plate to get it to accept the new mount.

I recommend getting a copy of APCC.   Your CP3 controller chip allows modeling and I would try to get the software and do the modeling.

You are going to love the mount.  Congradulations on your purchase.  You won't regret it.

Forgot....AP has a grease kit for about $40.  I would just try it as is for a while to make sure it works per specs without you messing around with it.  If you are like me, then you will want to "maintain" the mount and do the greasing.   Not much to maintain on these mounts, hence the word in quotes.

Thanks for the response! Which serial adapter are you speaking of?

Yes Ive got some work to do on that top plate.

I also just got a new to me 1200. Here is the serial to usb cable I used. I think anything using the FTDI chipset will be recognized easily by Windows. I liked this one for the DB9 hold down screws. It was cheap so I also bought a spare.

You need to make sure the chip in your controller is a new enough version to support APCC. If not, you can getvtge newer chip from AP and upgrade yourself. They can tell you which chip you have with your serial number. 

I agree, APCC Pro is an excellent addition. Highly recommended to get the most out of your mount.

A few more questions.   I notice that the mount comes with the PEMPRO CD from 2007.   Is this still usable to the current version ?  How would I do that if I dont have a CD Drive?

I had a very similar experience 6 months ago. I bought an old second hand AP1200 CP3 which was rarely used by the previous owner in Belgium.
I'm quite happy with the CP3, although I had to upgrade the old chip up to the newest V2 version available, with great assistance from the AP-folks involved.
Next I had some battery issues with the old GTO keypad but after reloading the latest software version, that is OK also. 
I did buy a new serial cable from Baader Planetarium in Germany and a serial to USB converter.
That works fine now, I can use the AP1200 CP3 serially connected (AP Ascom driver package) to most recent capture programs like NINA.

You'll be amazed at what this thing can do, it's steady as a rock.
Although it makes some screechy noises at highest slew speed (1200x) it's acceptable at 600x, but agreed I should also find some time to regrease it properly.
AP-specialists have sent me the recommended greasing lube and procedures.

So CONGRATS on joined the AP mount club.

PEMPro has no time limit on it.

I hear the power requirements are a top reason for problems!  You need to feed the beast!  Especially if doing high powered slews.    This particular unit has the updated chip and the battery has been changed in 2017 by AP.   Really looking forward to joining this group..... I dont deserve it!  


Abraham
 

And thanks for the warm welcome Tom!!  I appreciate it.  Look forward to bothering everyone here. Lol

Welcome to the Astronuts, Abraham!  This is a terrific group of very knowledgeable and supportive AP equipment users.  Members of the AP team chime in here and there, as well.  Bring on your questions and the group will do the best they can.  Congratulations on your new 1200GTO – we hope you have a great time with it!

The FSA is sitting pretty flat after some grinding, need to to some cosmetic correction but I think it will work.  I detect a tiny bit of rocking of the FSA but I think I can find that bump and correct it.    Question,  might be over thinking.  Drill and tap?  Or use nuts and washers?   I see the FSA is provided with 4 holes for mounting.  I plan on pretty heavy loads for this mount. Should I drill and tap a few more holes in the FSA or is this good enough?

Thanks!

My own AP1200 CP3 serial number is from the same timeframe, with a serial number very close to yours.  I noticed a couple Winters ago that slews were getting loud and screechy in the cold weather, seemingly struggling. I regreased the mount and it behaved like new again. I highly recommend it ! I will regrease it more frequently in the future.

Hi Mike, 

Good to know, and thanks for the info.  Ive not even pulled the mount out of the box yet.  I need to so if this mount has the old style clutch knobs or the newer version that dont splay out and cause binding.
