If you want to start to getting to know the software prior to receiving the mount, I believe you can get a temporary trial key.

APCC Pro license with new mount

Bob
 

I was certain I read something on this topic not so long ago but typically cannot find where, so apologies in advance.

The impending birth is now close so was wondering if the APCC license key is shipped with the mount itself, or is this something that must be obtained separately online?

Thanks

Re: AP V2 Ascom driver slew speeds wrong #ASCOM_V2_Driver

Ray Gralak
 

Hi David,

I've done this now and the V2 ASCOM driver is now reading Astro-Physics V2 Driver: v.5.30.10, 1200GTO
GTOCP3, Firmware: V2

However, the slewing behaviour is still the same: in the driver, a move rate of 12x gives a sensible result, but 1x
and slower are much faster than 12x.
Some of the changes in 5.30.xx involved changes to the move rate commands for the GTOCP4 and don't apply to the GTOCP3, which is now many years out of production. So, please try 5.21.xx as I suggested. You can install this version directly over 5.30.xx. Here is the direct link:

Since you mentioned the firmware it occurred to me that maybe I should install the version V2 ROM that I bought
some time ago but had not got round to fitting.

This problem didn't start with the latest version of the ASCOM driver. It started randomly. This makes me think it is

Theoretically, you could use an existing model if polar-alignment was about the same in each.

Also, you could do a short model run to get the polar alignment terms at the new site, and just update them in APCC, but there is not (yet!) an automatic procedure to do that.

A pointing model will improve both tracking and pointing accuracy,
including accounting for drift from polar alignment error.

However, if you move the mount you will need to recreate the model
from scratch, but that should not take much time. Usually, APPM will
do between 2-3 points per minute, so you should easily be able to do a
50-point model (25 points per side) in about 15-25 minutes. You can do this even before the skies are completely dark, thus not losing any imaging time.

The accuracy of a model is roughly related to the square root of the
number of points on each side. For example, going from 25 to 100
points per side will roughly double the tracking and pointing accuracy (because 100 is four times 25 and the square root of four is two!).

Liam,

 

I have to disassemble the scopes from the mount to do maintenance on the gears.  While down, I will run a CAT6 cable from the switch by the computer to the mount to have both ethernet and serial connections to the mount active.

 

Yours truly,

 

Jack

Jack,

 

Reliability is more a function of how you set a system up, than of the connection method itself. In your observatory, you probably have an issue with something like a driver, faulty cable, or faulty adapter. In my opinion (and therefore completely open to disagreement!), there is no difference in reliability between USB, Serial and Ethernet, so long as you perform regular maintenance to your system and keep cables, adapters and drivers current. That said, there is no need to limit yourself with connecting a CP4; you can run commands through every port at the same time and the mount will be fine. APCC has a way to run a backup COM port, so you can do something like Ethernet + Serial in your observatory.

I have my AP1600 with CP4 connected to the observatory computer using a Serial cable and USB to Serial adapter.  I use SkyTools to connect to and control the mount.  Occasionally I get an error indicating that connection to the mount has been lost.  I re-establish the connection and all is fine.
Would using a CAT5 or CAT6 connection from the CP4 to the computer provide a  more reliable connection to the mount?
Can I have the mount connected to the computer using both a CAT cable and a serial cable?
If so, which connection takes precedence?

Yours truly,

Jack Huerkamp

I recently used the  Mach2 gto  with the ASI air pro and they worked fairly well. Uou need to connect it as the gtocp2 .(strange but teie) and you must have the USB cable connected from the control box to the ASI air box usb  to allow it to connect it wirelessly. Of course you 
Have to configure the gtocp5 control box to station mode and link to the ASI air wifi.

Only the  go home button on the ASI app does not work and you have to use the keypad to get it to go back to your correct park position. Not sure if there is some step I missed . 

How this will help those  planning to use this setup.
