Re: AP1100 GTO with AE installed today - but newbie question #Absolute_Encoders

Rolando,

Thanks to George and Liam, I was able to program the personality #120 into the CP4, VIa APCC now I see encoders enabled. Does one blue and one gree light mean the signals are solid?

Besides melting into the background, is there anything I need to be aware of with AEs on the AP1100 GTO?

M Hambrick,

That is an excellent solution for storing the counterweights and CW bar.  Your photos really help to visualize the possibilities.  Now, I need to hunt down a supplier for the high density foam.  Thanks for sharing the fruits of your ingenuity.

Thanks Mike for the reply,

no other COM ports are listed.
Try this:
1. Turn on the mount and plug the USB-serial dongle for it.

2. Open Control Panel->Device Manager->Ports COM and LPT (see attached screen shot).

3. You should see COM5 listed.

4. Now plug the Solar Guider into a USB port. How does the list of ports change in Device Manager?

I don't know anything about the Solar Guider. Is it a camera with its own USB cable? If so, then Device Manager should show a new port when you plug that cable.

*** If it does not, then your laptop does not recognize that device. In that case, you probably need to install a Solar Guider device driver.

Do you see any message in the Windows System Tray (lower-right) when you plug the Solar Guider? That could be a clue that the device driver is missing. Or perhaps Device Manager shows a new port with a yellow question mark that indicates the device is not working.

As far as I know, Device Manager should display a port for every USB cable plugged into the PC. If it does not -- and only the mount's COM5 port is shown -- that explains why the Solar Guider software is choosing COM5. You need to get Solar Guider's port to show up.

That depends on the type of USB-serial adapter. My Edgeport USB-serial box lets me specify what port to use, but Control panel -> Device Manager on my Windows 8.1 machine doesn't.

When I try to plug in something else (in my case a solar guider)
to my laptop it also wants to connect to COM Port 5. Not sure why it's
trying to use the same Port
That sounds like an application setting. All the software I use has a setting that allows me to specify the COM port to use. This is saved in the app's configuration, so it always uses that port.

I suggest first checking your solar guider settings; then you'll know why it's trying to connect to a specific port.

HTH.

Re: APPM Models

Worsel
 

Lee

Here is an excerpt from the APPC Pro manual on pressure.  The highlight below is mine.  MGPV2 Box will send local pressure to APPC via the astromi.ch ASCOM driver.

Pressure: Here you can enter the approximate atmospheric pressure. This is used for refraction
calculations. The atmospheric pressure varies based on two principal factors: the weather, and your
altitude above sea level. Note that this differs from typical weather forecast "barometric pressure" which
is the atmospheric pressure normalized to sea level. Do not use barometric pressure values. Light is
being refracted by the actual air mass above your telescope, not the equivalent normalized sea-level air
mass. As an example: mean sea-level atmospheric pressure = average barometric pressure = 1013
mB. The Astro-Physics observatory is at an altitude of about 228 meters above sea level - none too
high. The sea-level value of 1013 mB is equivalent to about 987 mB of actual atmospheric pressure here
at AP. At a remote observatory in Chile at an altitude of 2295 meters, that same sea-level value is
equivalent to about 770 mB.

For any given altitude, the atmospheric pressure will have a certain range of variability that can be
expected. Within the range at your observing spot's altitude, you will find that higher pressure
corresponds with nights where it is clear enough to actually use the telescope, and lower pressure
corresponds with cloudy or even stormy weather. When manually entering a value here, enter one that
corresponds with the high pressure value for your altitude that you would be likely to find on a good clear
night. In a future release, APCC will add support for weather station software so that this value can be
kept updated in real time.

Re: APPM: model start and point by azimuth /altitude #APCC

 

Hi Andrea

In my experience APPM does not work that way at all, but it's much easier. You define a set of points in the sky, run the model, sit back and it finishes. You only get one shot at the model (there isn't an incremental way to build it [yet?]).

it's very easy and you can see a graphical representation of your model as you tweak the settings but before you commit to it.

Hello,
I am going to use APPM, and I have experience with tpoint.

In Tpoint you can define a set of points close together to quickly start with the corrections and then continue on more distant points.

I wonder if this is feasible in APPM:

-set an initial group of points
-define subsequent groups of points , that enter the models
-define the points by azimuth and altitude.

Not that this is strictly needed , it is just that I am used to this way of working and want to leverage on my experience if possible.

Re: Can't Connect To CP4

Calypte
 

Some years ago, I decided that I wanted to set up a home wifi network.  It's standard stuff now, but at the time I thought it was pretty special, and I thought *I* was special for doing it.  I thought that I should try ethernet before plunging into wireless, since ethernet was the older, more established technology.  I got ethernet to work, but it turned out that ethernet was more complex and touchy than just going wireless from the start.  With wireless, the software just goes and searches for a network and connects.  What I thought was hard turned out to be easy, and what I thought was easy was hard.  I'm sure this is all old hat to people who work with networks.

Here is what I put together for my counterweights using the short Ridgid toolboxes originally suggested by Tony (a.k.a. Harley Davidson). I need two cases to hold the counterweights for my 1100 Mount; one holds two 18 pound counterweights with room for a third. The other holds the counterweight shaft, an 18 pound counterweight, and a 10 pound counterweight. The foam in the lids is 2-inch thick. There are two layers of foam in the main part of the case. The base layer is 1-inch thick. On top of that is a 2-inch thick layer with the cutouts for the counterweights and shaft..

Both cases are heavy. I set up and take down my mount every time. I have found that if I use proper lifting techniques I can carry all of the counterweights to the mount in one trip. Carrying them piecemeal (one in each hand) requires three trips, so these cases are big timesavers when I am setting up.

The foam is closed cell high density (1.7 lb) foam. I think the grey foam is actually denser, so if you can get that it is better.


Re: Storage box for the Mach2 mount

Slightly off-topic, but I’m looking for storage/transport boxes for my AP900GTO. The Ridgid boxes are not on sale here, but I’m looking into the similar MAXIMUM wheeled box set. It’s a tight and awkward fit with both assemblies in the one large lower box. I could use it, but I’d prefer some kind of protection beyond towels (which I have seen used in one online video), perhaps cubed pick foam. Are you using anything in your Ridgid boxes?

Re: Can't Connect To CP4

Dale Ghent
 

I've always thought that the CP4/5's ethernet/wifi connectivity would be a prime candidate for running a multicast DNS (mDNS) and DNS-SD (DNS-base service discovery) service, as that would greatly simplify these kinds of initial setup and subsequent use steps and would obviate the need for the IP finding app. If directed to connect to the CP4/5 over the network, APPC or the ASCOM driver would "ping" the network for a mDNS name that is unique to the CP4/5 and then use the reported IP address. The user would never have to see an IP, let alone look for one. I seem to recall that the embedded OS+software framework the CP4 uses has the ability to set this up, but I might be conflating that with something else.

I see that you got it working, but for the benefit of others that might have the same problem:

Connecting directly to a device with an Ethernet cable usually requires that
you set up your laptop to use APIPA (Automatic Private IP addressing 169.254.0.0-169.254.255.255).
No, I have not seen that referenced anywhere. How do I do that?
It depends on whether your computer/laptop sees a DHCP server or not (e.g., a home WiFi router).

If the computer sees a DHCP server, and the computer is set up to use DHCP, the LAN port may get set to a subnet different than 169.254.x.x, so you probably won't be able to detect the CP4.

Some choices:

1. You can either turn off the WiFi router and reboot your computer. This should allow the LAN port to default to APIPA addressing. If it doesn't, you can change the settings manually.

2. You can manually change the computer LAN Port's TCP/IP V4 settings to use IP subnet 169.254.0.0, with subnet mask 255.255.0.0 (or Subnet Prefix Length = 16).

https://support.microsoft.com/en-us/windows/change-tcp-ip-settings-bd0a07af-15f5-cd6a-363f-ca2b6f391ace

Remember to save and restore your settings afterward!

3. If you have a DHCP server, instead of connecting your computer directly to the CP4, you could connect it to your LAN via Ethernet cable. Note that WiFi won't work by default as it will not have been configured yet.

After connecting the Ethernet cable, power cycling the CP4 should allow it to acquire an IP address on your LAN via DHCP.
