Peter,

 

I believe Optec’s system is called Focuslynx and Starlight Instruments’ system is called Focus Boss.

Re: Which GTOCP* connection do you use?

The serial connection of my AP1200 GTO CP3 is connected to my laptop via an FTDI serial to USB adapter. The USB end is connected to a powered 7 port USB2 hub, which also services the guide and imaging cameras plus a powered Hitec Mount Hub Pro, which in turn runs my Moonlite focuser and 3 dew straps. There is single USB2 cable between the observatory laptop and USB2 hub.

Geof

A new poll has been created:

I am toying with connecting via ethernet to save a USB space on my control computer.  I have also ordered an FTDI serial adapter to try that out.  Therefore I should only need 1 USB cable to my entire imaging rig.  What are your connections and why?

1. USB
2. Ethernet
3. WiFi
4. RS-232

Also CP3 - RS232 to an ancient usb adapter to a USB3 hub.  Everything else (EFW, camera, focuser, guider, etc) also connects to the USB3 hub, and that is the sole connection to my observatory laptop.  The observatory connects to the home network via a wireless bridge.  The laptop is then accessed remotely through Google Remote Console.

Jack,

If you go into the hand controller it gives you the option of setting it to utc.  I also   
have Dimension 4 installed on my laptop which keeps it synced to a UTC standard.

I noticed the guide star was out of the field so I grabbed an additional full frame exposure through the guide camera to see what had happened. A 5 sec exposure showed stars streaking in the field of view, like the tracking was incorrect or even off.
 
After closer inspection I noticed that the mount parked itself at exactly 2:00am when the PC's clock automatically advanced from 2:00am to 3:00am during the EST to DST transition. It wasn't too much of a problem since I was closing down for the night anyway, so I lost the 10 min subframe.
I was wondering why/how the mount automatically parked due to that sudden time shift Any ideas? Anyone else had this happen to them?

I connect to my CP3 via a usb to serial adaptor which is connected to a Pegasus Astro powered USB 3.1 hub mounted between the forks of my AP900GOTO. Also connected to the hub are the main camera, filter wheel, guide camera and Optec FocusLynx hub. I connect to the hub from my control computer in my house with a 65' powered USB cable. I use MaximDL Pro 6.11 for image acquisition and focusing and The Sky6 as the planetarium program.  All works very reliably.

Re: Which GTOCP* connection do you use?

You cannot plug a Mach2 into a CP4. Plugs are not compatible for one thing.

The CP5 is no different from the CP4 as far as software. If your ASI air will connect to a CP4, then it will also connect to a CP5. There is no difference on the front end.

Rolando,

 

Thanks.  That is what I thought.  George already responded to me in that regard.

 

But, is there a waiting list for the Quick Release Gearbox Modifications to existing AP1600 mounts?  You stated that you were machining spare gearboxes, and I am interested it getting an upgrade when they become available.

 

Yours truly,

I have the DOVELM162 mounted onto the AP1600 and I think there was only one position I could place it in to allow me to use all the bolt holes tapped in the top of the mount.

Re: Which GTOCP* connection do you use?

Dale Ghent
 

Negative. The CP5 is (currently) unique to the Mach2 because the CP5's motor driving circuitry is for running the unique-to-the-Mach2 brushless servo motors. The CP1/2/3/4 has circuitry for driving the "classic" servo motors that are in the rest of the GTO line, past and present.

You can't even accidentally do this because the CP<=4 classic servos connect with a single connection, where the Mach2+CP5 has separate connections for RA and Dec motor and, if memory serves, the gender and keying of the connectors also differ.

I read through the Balancing Side-by-Side procedures you provided a link to and understood everything until I got to Steps 6 through 9.  Photos would sure help me visualize what is going on.

Is the Primary Saddle Plate removed from the mount when doing these steps?

I have the DOVELM162 mounted onto the AP1600 and I think there was only one position I could place it in to allow me to use all the bolt holes tapped in the top of the mount.

Yours truly,

Kenneth,

 

NO…no…no!    Do not even try that.   Your CP5 is personalized to your Mach2.

Can i use the gtocp4 with my mach2 gto? I was toying with the idea as that will allow me to connect it with the ASI air pro which does not seem as yet to support the gtocp5.
