I realize this is not exactly something that hasn't been done before, but it's the first time I've tracked an asteroid and made this kind of video.  The Mach2 definitely made it easier than it would have been with my previous mounts.  YouTube link here.

Re: Mach2 intermittent loss of connection

 

Hi Marty

one thing to confirm is you are using TCP and not UDP?

I found UDP to be unreliable and cause intermittent connectivity issues

Thanks, Ray.

I did try to select "none" for the backup connection but the setting didn't "stick" when I reopened the program. I must
not have saved the settings, or an earlier version was being loaded. I'll look into that.

I'll collect the log file. Don't have access to any dropbox, etc. places to allow you to collect it. I emailed it to you

I think I'll set up a COM port backup. Will need another USB-serial adapter.

Re: Who needs absolute encoders!

M Hambrick
 

Are there any users out there with absolute encoder equipped mounts who set up and take down their rig every observing session ? If so, what has been your experience with the absolute encoders ? Are they worth having on a portable setup ?

I am asking because I am thinking about upgrading my 1100 mount to absolute encoders, and I set it up and take it down each session.

Re: Issue with DOVELM162

Hi Paul

From what I can tell, the Allen head in the clamp looks like the head of a standard 1/4-20 socket head cap screw that has been press fitted into the recess hole in the aluminum clamp. The knurling in the head helps to hold it into place. This is very similar to the way that the lug nut studs are attached to the brake drums and rotors on cars.

Unfortunately, once this Allen head strips out and breaks free, it would seem that the only recourse is to order a replacement. However, even with a stripped Allen head however, the clamp itself should remain functional. You just won't be able to use an Allen wrench to tighten or loosen it, but pliers, the green jar lid gripper, or the strap wrench all mentioned above will work.

I never use an Allen wrench to tighten these clamps, even with my heavy 180 EDT imaging and guiding setup. If I need to torque them a little more, the jar lid gripper works really well, and it also works really well for loosening the clamps. Before using the jar gripper, I used to need an Allen wrench from time to time to loosen the clamps.

Hi Marty,

I'm using the Ethernet connection via a reserved IP address. When it fails APCC tries to look for a backup serial
connection, which I don't have. The Ethernet connection is via a managed POE switch, which appears to be
operating flawlessly. All of the cables are of high quality and were tested first.
First, if you don't have a COM port connected to the mount, you should disable the backup connection by selecting "None" in the "Backup Port" drop-down list. This will keep APCC from switching from Ethernet to a COM port. This would help because if APCC switches to the backup, it will continue to use the backup COM port (which is not connected to the mount) until you disconnect/reconnect, as you discovered. Whatever Ethernet issue happened, which could have been something Windows-related, might have recovered after a period of time.

Of course, one possible way to handle this would be to install a COM port backup cable and configure APCC appropriately.

Would it be possible to get your log files from last night so that we can investigate this? It would be best to use the APCC Log Zipper utility, which is installed along with APCC. Then provide a dropbox, google drive, or one drive link to the zip file.

The mount was reported as "Parked" but hadn't moved to a standard park position.
This is controlled by the Park position defined in the "Safety Park" group box on APCC's Park tab. There are three options: "In place", "Home position", and "Configured park position". You want to select the last option if you want the mount to move to the standard park position if APCC loses contact. By default, APCC will park the mount "In place" (i.e., its current position).

Subject: [ap-gto] Mach2 intermittent loss of connection

Hi everyone,

I'm running a Mach2 with APCC Pro, TSX Pro and SG Pro all interacting. It has worked very well with one
exception: I get intermittent and (to me) unexplained loss of communication to the mount. If I am there I have found
that telling APCC to disconnect and reconnect solves the problem almost all of the time. Last night, however, I
wasn't there and I loss a bunch of subs because the mount stopped tracking. The mount was reported as "Parked"
but hadn't moved to a standard park position.

This has never happened when I am just talking to the mount over APCC. It happens only when the ASCOM driver
is also in operation to support TSX, SG Pro or another program. All of the software is up to date. Using latest
Ascom platform.

I'm using the Ethernet connection via a reserved IP address. When it fails APCC tries to look for a backup serial
connection, which I don't have. The Ethernet connection is via a managed POE switch, which appears to be
operating flawlessly. All of the cables are of high quality and were tested first.

Questions:
1. As anyone else experienced this and found a simple solution?
2. Does it make sense to install a serial-USB secondary connection to the computer, as backup? Would that help?

Thanks

Marty

Re: Issue with DOVELM162

If an allen bolt unbonds from the knob, I find the safest way to loosen a knob that is beyond hand tight is to use a strap wrench. The strap wrench is the astronomer’s secret weapon.

That’s OK no need to bother, so long as I do not need to buy anything else, I’m OK and will figure it out with hardware in hand.  I didn’t mean to sound like I did not believe you, trying to follow along in the manual.

The back of the 1100 itself. I will get you a photo here in a few. 🙂 I use the Losmandy HD and the 119FSA which is basically what the adapter you showed is.

That’s good to know, and I just saw the detailed “what’s included” list shows the CBAPT”.   Good.  But that it attaches to the mount is a bit at odds with page 16 of the CP4 manual, which says:

 

When using the 400GTO, 600EGTO, Mach1GTO, 1100GTO and some

of the OEM mounts that use the AP Servo Drive System, the GTOCP4 is not directly

attached to the mount, but instead it is mounted onto a bracket that is then affixed to

the tripod or pier.

 

So the bolts that hold the base to the Berlebach plate will be what the CBAPT attach to?   Or it does attach to the 1100 itself?

The pier adapter for the CP4 comes with the mount.  It will connect to the backside of the 1100 with two screws. So you will drop the RA axis onto the adapter you pictured, secure that with the bolts on the side, then bolt the CP4 box on the back of the mount itself.

I am anticipating a AP 1100 in a few months, and have that plate on order for my Berlebach Planet tripod.   From their website it looks like the attached.

 

There is a “Pier/Tripod Control Box Adapter” that shows as an angled bracket for attaching to a tripod.    The CP4 manual indicates the 1100 needs something on which to attach the CP4.  The 1100 manual on the other hand, on page 8, is a little confusing as it shows two screws for the CP4, but on the left hand page mentions “& adapter”.   So I think the adapter is there.  Maybe. 

 

Does anyone have this mount on a Planet, specifically one with the Berlebach plate? 

 

Will I need the adapter?   I’m thinking yes.

 

Will that top hole on the adapter (the one on the bent piece of metal) attach to a screw that’s going to go into one of the four holes below?  Or am I going to need something else with which to attach either the CP4 itself, or the adapter?    Will just that one screw hold it?

 

I am hoping not to drill holes in the wooden legs.

 

But even more, I want to make sure when I get it, I have all the parts.  Be a shame to then wait weeks to order some minor but necessary part.  L
