We make a Height adjustable pier (PierTech 2 or Piertech 3) its both portable like a tripod and you can also use it in a observatory as a mounted pier. You can attach your mount and OTA at 35 " from ground and then raise it a full 20 inches, keeping polar alignment and level!

Hello Karen
I just noticed that the polar alignment app has been removed from the Apple App store. Is there going to be an updated version coming?

Just a reminder for those who are waiting for Mach1 mounts and have Renishaw low temp encoders ordered, the delivery of the encoders has been affected by Covid shutdown. We are anticipating delivery some time in February, so it won't be an interminable wait. We did contact everyone on the list but may have either missed someone, or it ended up in their spam file. Please be patient, we are working as fast as possible to get these mounts out.

Patiently waiting for my Mach2. I loved my 1100GTO when I first got it in 2014, upgraded to the encoders last fall and love it even more. So, I can’t wait to get my Mach2, hope the low temp encoders come in soon...

Re: USB and cold weather

Barry Megdal
 

Just a general comment about USB and cold weather.  It turns that that low-cost USB gear (whether cards in the back of PCs or hubs, etc.) often use ceramic resonators rather than quartz crystals to produce the needed clock frequencies.  USB is not very tolerant of errors in clock frequency, and ceramic resonators change frequency far more than quartz crystals with temperature.

 

So pay attention to specified temperature range for USB gear, and stick to commercial products where the given specs for temperature are likely to be more meaningful than with consumer gear.

At What Temp Do I Need 15V For My AP 1100 Mount?

Kent10
 

In the winter, I often observe in below freezing temperatures.  So my 1st battery was one from Kendrick where I could use 15v instead of 12v.  15v was recommended in the AP 1100 manual.

 

I am looking at getting a new battery.  I could just replace the Kendrick battery but am considering the LiFePO4 batteries that so many people like. 

 

If I buy the LiFePO4 battery, I assume I can no longer use 15v.  Can I successfully use 12v in 20 degree F temperatures?  I don’t usually observe much below that.  I prefer not to slow down the slewing speed.  Or is there a way to use 15V with the LiFePO4 battery?

 
Thanks, Kent

 

 


Re: USB and cold weather

 

On the topic of through mount USB3 and USB2. 


USB 2.0 will work just fine, for a number of reasons. Most notably, there is far less communication actually happening between device and host, at a far lower speed, with far less 'protocol' communication. With most devices on the market, this is all you will ever need, and I could not make it fail in testing. 


USB 3.0 is more tricky. As Roland mentioned in the thread, signal will bounce off of interfaces at the frequencies of USB 3.0, echoing in the line. The best way to deal with this is to ensure the least number of interfaces and shortest wire path between powered USB 3.0 ports. In the Mach 2 manual, we make some suggestions for USB 3.0 configurations that I have tested and can confirm to work perfectly. They all come down to having some kind of booster or powered hub right at the connector at the base of the mount, and a powered hub at the top of the mount. The internal cable is very high quality, but no amount of quality can prevent interface reflections. 


An easy way to test your USB 3.0 setup is to get a USB 3.0 hard drive, and set it at the top of the mount. You can then use a USB speed tester program to see what quality of data transfer you get. I used USB Flash Benchmark with very good results. If the test fails, or Windows has a hard time detecting the hard drive, it means that the cables are too noisy to do proper communications and you need to reduce the cable length/connector interfaces between powered USB ports.

The GTOCP3 can be used with APCC as long as it has the latest V2 ROM chip.  Of course, the GTOCP4 has all the latest bells and whistles, and will take advantage of all the features that APCC can offer.


Re: APCC Pro version update

Ray Gralak
 

Greg,

As I have said several times before, APCC is a .Net application and thus depends on the .Net Framework. If your system has a problematic version of .Net Framework, there may be a bug that needs to be patched. Other apps that were mentioned, like PHD2, are not .Net framework apps.

It could also be that when you first installed and ran APCC, you did not allow APCC to communicate by canceling the firewall popup message. If you do not allow APCC to communicate, it will be blocked.

While I agree something is blocking APCC's code and no difference between APCC on each computer

The question is what difference and how were those applications able to be installed or access some OS code to

(or do other applications also have issues?)

I also have other apps that can get version data on two computers that all work except on one of my computers,

I wonder what the difference is and how to get around it as I set up both computers and keep them both updated

turns out my tpoint us giving me a bum polar alignment.
I used Pempro polar alignment wizard to check the polar alignment as I was getting a lot of drift.

my polar alignment was waaayyy off. Corrected it using Pempro and got some imaging done.

I’ll have to check into what happened with tpoint being so off.

Tume to switch to APCC. Does it work with CP3 or only CP4? Is there hone switch upgrade available for the AP1600?

Re: USB and cold weather

All my hubs are 12v powered.  And I have been only using one hub until the test.


Re: USB and cold weather

Micheal Fields Jr
 

That was just an experiment to see what would break first.   The idea being that if the worse case senario works but it still doesn't work through the mount, then I have isolated the problem.   Also as Roland mentioned, maybe having extra power and signal integrity before it goes through the mount and after it goes through the mount will provide a more stable situation.  So that is why I experimented indoors with using two hubs.  That is not how I have been doing it up until then.  I was just testing ideas.

Should have mentioned that this is a CP4 and I do use the ETHERNET
connection but the computer is in the observatory so I'm guessing it
is seeing the IP address of the CP4 and if that failed for some reason
it would have gone to the serial connection but that also doesn't seem
to have been an issue as far as I can see.
An occasional error will not cause APCC to switch to serial. It requires
multiple failures in a row. And even if it does switch, APCC will not repeat
a failed command.

This seems to be an unfortunate, intermittent failure on your network.

For APCC to get into this state, something (an ASCOM client

near the end of the park operation.

Hi Steve,

This is a recurring problem that I've often blamed on ACP but am
rethinking this as the screen shot shows ACP attempting to park,
the ASCOM
driver says it's parking, and APCC says it is parked.

Your screenshot shows the mount is unparked, with tracking
stopped, according to APCC.

There's no way to know for sure what happened from a screenshot,
but because the mount is not parked, the driver cannot indicate
that the mount has completed parking.

This is a recurring problem that I've often blamed on ACP but am
rethinking this as the screen shot shows ACP attempting to park,
the ASCOM driver says it's parking, and APCC says it is parked.
I'm guessing that ACP gets the information from the ASCOM driver
so yes, it actually isn't parked. This is a rare problem but
when it happens, once long enough to have let rain fall on the
equipment, it causes real problems. The mount must be parked
before my roof can close so using a direct close on moisture
reading can't work. I had hoped to find a solution but I don't
see this now. The screen capture shows the
roof closed only because I closed it using the close command in
AstroMC and the mount was already in the Park 4 position and had
been since 0623. The last image had downloaded at 0531 and the
shutdown script was executed at
0623 if I remember correctly. It was a brief notification from
Windows
10 but those were cleared after reading. Not sure if any record is
made of those.
ACP doesn't have a shutdown record as it seems that is made
after it completes which it didn't. If there is a log somewhere
else to backup this event I'm unaware. Maybe APCC can pinpoint
the time as it seems to
show the mount parked?



Anyway the issue remains, the roof was wide opened, scope was in
the Park 4 position, my inline Microswitches wired in series
were both closed (continuity signal to the relay) proving a safe
position for the roof to close, the roof was manually directed
to close in AstroMC which it did successfully, and yet ACP still
shows the mount as
"Parking"
as does the ASCOM driver but not APCC. The difference is that
ASCOM and APCC show the mount at the parked position whereas ACP
shows what I assume is the position it was prior to being commanded to
park.
So the question is, where is the log jam and who is responsible
for the
stall? How can I prevent this?



I hopefully will have Good Night System fully configured today
but that only notifies me via smart phone of these failures if
I set it up
correctly and I have cell signal. It doesn't correct anything. The
system is still in this "Parking"
phase and I'll leave it like that hoping that Bob Denny or other
person has some idea to tracing the problem. I can stop this and
power everything off and start from scratch with a startup
script run but that only puts me back at square 1 and doesn't
identify the problem. Is it
a communication issue where a request is sent and waits forever
and if so why can't there be a reasonable time restriction before
another request is sent or other action is taken?



Wide open to ideas/suggestions.
