Hi George,
 
    At over $700 a seat for “commercial use of their TeamViewer” program, it seems reasonable to just make the contact and explain that you are using it strictly for personal astronomy, and not as a tech support person. I think you may have downloaded a new copy and specified it would be for business – possible error?
 
    The other thing I found, some years ago,  was that if you are using TV only 300 feet away, then DO NOT use the 9 digit user ID, but go into EXTRAS in the menu, and change the OPTIONS, (General, Incoming LAN connections) to the IP address of the host PC (laptop) at the telescope. The 9-digit ID code is fine if your telescope is really remote, off-site, so you have no choice but to trust the internet signal stability, but you need not do that transmitting to the backyard.  That way you aren’t going across the continent, or an ocean, to their head office in Germany for a host login – and then all the way back to your backyard.
 
    The IP method, is local, to just your house. That would explain “drop outs” because you can’t trust the internet to be as stable, as the short hop from your modem/router, rather than the thousands of miles, across many network nodes on the planet to get to TeamViewer base.
Check the other menu tabs for interesting settings, as well. I suspect you just used TV as-is without investigating the EXTRAS tab. It really is a great program, once you discover the proper option settings.
 
    I wonder if that rash of disconnections and reconnections, made it appear as though you were contacting different (business) support clients each time. They don’t know who is at the other end, just that you made a lot of short connections in a very short period – so it looks suspicious to their computer activity
 
    The other common cause of drop outs is running your microwave oven near the client PC in the house (e.g. kitchen ?), or other 2.4 GHZ  such devices ( for greatest range) conflicting with your router signal using almost the same frequency – e.g. neighbour’s security camera, nursery room monitor, cordless phone handset, kids gaming devices, garage door openers, etc. etc. They can interrupt or drop your connection, and then ...  don’t even bother paying any attention to the TV pop-up, saying that it is “Reconnecting” – it always fails. After about 11 minutes, I find it just gives up. The far quicker method, for your client PC, is to simply close the active TeamViewer client Window as soon as you see the drop out, and click on the TV Login quickly again. You will be reconnected in a matter of a few seconds, without losing a heartbeat of the scope’s activity, since it wasn’t even aware that the client's connection was lost – when its scope PC was just carrying on with what it was doing – control, imaging, etc.
 
    If you can get TV working again, it is probably far better to have something you are familiar with using.

When and if APCC says it can’t shut down due to a connection you simply double click the driver icon in the system try which opens the driver window. In the left upper corner you’ll see the number of connections. Double click that and end the connection. Easy peasy. The problem is something is either not disconnecting or hasn’t been properly disconnected.

I have been using TeamViewer (free version) for several years to remotely control my observatory, only 300 feet away.  All of a sudden, this year, I get disconnected in the middle of a session, with an alert that there is “suspicious activity” and I may be using TV for commercial use!?!? You cannot reconnect for 5 Minutes, whereupon you get 5 more minutes before you are disconnected again. I see many complaints about this now, and TV wants you to go to their site, affirm that you are not using it for commercial purpose and maybe they’ll get back to you in a week. Lesson learned. You get what you pay for. For a mission critical application like this, I will no longer rely on “free” software.

 

GoToMyPC is the highest rated remote desktop SW around, apparently. So, I downloaded the 7 day trial. I ran it through the hoops, APCC, ASCOM V2 driver, The Sky 6, and SGP. At the end of a session, I disconnected the V2 driver, then disconnected APCC. APCC would not shut down, claiming other programs were connected – the V2 driver! I could not get the V2 driver to end, gracefully. I finally killed it, shut everything down and started over. This time, I only brought up APCC, connected to the mount, then connected V2. Same problem, V2 would not disconnect.

 

Looking over the remote desktop field, I decided to try Remote Utilities. Free – even for commercial use on limited numbers of PCs  (if push comes to shove, it is a one time  $99 purchase). I installed this and ran the same 2 scenarios as above, but the V2 drive disconnects as it should and there was no problem!? Weird. Cannot explain it, but Remote Utilities looks like my replacement for TeamViewer.

Re: First Light with CMOS camera - M8

Thanks for the explanation Joe. My setup is a USB 3 hub to a USB3 port. On my MacBook Pro both USB  ports are USB 3. I was looking at the system details and saw that the system divides all the USB traffic into sets of 4 port hubs of either USB 2 or 3. 

I was using the USB3 cable I had bought for the camera  at my desk for the darks and got a communication error to Nebulosity.  I need to confirm with testing but that is probably the culprit.   I hope that is the case. 

I added more saturation to the image.

Hi Robert,
 
    USB-2 hub technology is a bidirectional “two way alternate” technology, whereas USB-3 is “differential, two way simultaneous” transmission. This idea goes back to the days of using copper wire serial port cabling and synchronous transmission (current loop) used in early days of computing, predating PC’s. Synchronous serial ports back then improved speed using a separate line for sending & receiving.
 
    If you want better performance when sharing USB accessories, especially (the now out-dated) USB-2,  with USB-3, you would be very wise to use a USB-3 hub going to a USB-3 port on the PC. A typical  USB-3 hub splits USB-2 traffic from the USB-3 traffic, so there are effectively two highways, and the USB-3 is even a double lane road. USB-3 hubs have separate comms chips to accommodate each technology, so all the USB-2 traffic has to wait in line for to their send or receive, for each such device and also whether sending or waiting for a response. Meanwhile USB-3 accessories (inside the same hub),  use the fast lane and don’t wait for, or collide with traffic coming in or going out between the USB-3 accessories sharing the USB-3 hub and the host USB-3 PC port.  The USB-3 hub really acts & performs as two independent hubs.
 
    So, if you MUST share USB-2 and USB-3 accessories,  using just ONE hub, make it a USB-3 hub, perhaps a 7-port device, and attach it ONLY to a USB-3 port. Otherwise the USB-3 hub just falls back into the slow USB-2 mode for everything shared to it. Then your only option is two USB-2 hubs or attaching directly to a separate  USB,  PC port.
 
    You can Google the USB technology consortium,  for more info on the differences - Your best performance with much reduced traffic conflict, is a USB-3 hub (for mixed USB type devices),  plugged into a USB-3 PC port.

If you have an ASI294 and are using the flat ribbon-style USB cable that ZWO cameras tend to ship with, ditch it and replace it with a proper USB cable. I don't know why ZWO continues to ship them with their cameras, but those ribbon cables are poorly shielded and create trouble (such as random disconnects) in even semi-noisy environments.

I suggest checking that no other USB devices are hogging the bandwidth while imaging.

I have an ASI1600 MC Pro, and MaxIm would occasionally hang up while reading or downloading an image. The camera went back to China, and engineer Chad at ZWO found no problems. After I got it back, the problem persisted.

It turns out the hang occurred only when I was viewing the observatory interior on a webcam connected to the observatory PC. (I operate remotely from inside the house, and occasionally used the webcam to check that everything is OK.

I disconnected the webcam, and the '1600 has performed perfectly in the ensuing five months. No hangups or bad subs at all.

The webcam was USB 2, and the '1600 is USB 3.0, but clearly the webcam data was affecting the '1600 in some way.

I replaced the webcam with an Ethernet security camera.

Normally I would say that anything that even looks like a good cable is /probably/ better than the one that ZWO supplies, but certainly well-constructed USB cables abound. I get mine from L-com.com, but pretty decent (and more readily-found) cables come from companies such as Tripp Lite, Inland, and QVS. USB2 cables are pretty forgiving, but when it comes to USB3, one really needs to pay attention to construction quality. The signaling constraints are a lot tighter there.

Anker USB cables seem to be well built.

Normally I would say that anything that even looks like a good cable is /probably/ better than the one that ZWO supplies, but certainly well-constructed USB cables abound. I get mine from L-com.com, but pretty decent (and more readily-found) cables come from companies such as Tripp Lite, Inland, and QVS. USB2 cables are pretty forgiving, but when it comes to USB3, one really needs to pay attention to construction quality. The signaling constraints are a lot tighter there.

Hello Dale,

Do you have any specific recommendations with regard to the proper USB cables?

Thanks,

Nice job and wonderful detail!

If you have an ASI294 and are using the flat ribbon-style USB cable that ZWO cameras tend to ship with, ditch it and replace it with a proper USB cable. I don't know why ZWO continues to ship them with their cameras, but those ribbon cables are poorly shielded and create trouble (such as random disconnects) in even semi-noisy environments.

Re: ASCOM driver questions

Ray Gralak
 

Any ideas what could cause Windows to crash?
The AP V2 ASCOM driver is a user level process and cannot cause windows to crash, but the USB/serial driver could a bad USB/serial or graphics driver could. SkyX uses Windows graphics card drivers. Try updating the drivers to both.

The other problems may be caused by the USB/serial converter or a bad cable to the mount. Also, if you are using a USB hub, take it out of the loop and connect your USB cable directly to the mount from your computer.

Subject: [ap-gto] ASCOM driver questions



I have an AP1200 GTOCP3 and I'm using the latest versions of TheSkyX (build 12304), ASCOM platform
(6.4.1.2695) and AP ASCOM driver (5.20.09).




I'm often seeing issues where TSX requests a slew but nothing happens or alternatively TSX reports the status as
slewing when the slew has completed. If I perform a disconnect and reconnect of the telescope in TSX things start
working again for a while.




I also find that if after parking I forget to close TSX/ASCOM driver before unplugging the Keyspan USB/serial
cable my Windows 10 laptop sometimes reboots.




Are others experiencing this behaviour?





How can I determine whether these issue are with TSX or the ASCOM driver?




Any ideas what could cause Windows to crash?




ASCOM driver s are DLLs rather than Windows system drivers, aren't they? Assuming so, I'm not sure how either
TSX or the ASCOM driver could directly cause the crash.




Regards,

Gavin

1600 GTO balance question

Mike Shade
 

There was something a few days ago about balance on a 1600.  I believe someone offered that if the mount is significantly out of balance there can be some issues with the gears or some such thing.

 

I have a first generation 1600 and it will rarely be somewhat out of balance (removing the imaging train to check collimation or the very rare visual foray).  How much out of balance is tolerable?  There is no way to rebalance the OTA, which weighs 140#.
