Steve.... What happens if you click the Park button in the ASCOM driver when the mount is in that situation? Does the driver flash "PARKING" and does the mount move to the specified park

Hi Steve, 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,

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.

Not sure this idea will help but my Nikon D800 uses a USB3 cable and I commonly had problems with connectivity, especially in the cold. Now I use the following: from the camera I use an 18 inch USB3

A bonus for using USB-2, besides 3x the distance, is that those cables are “thinner”, by two extra wires in the sheath, than USB-3. So, the cable bundle inside the mount is just a bit looser,

In automotive applications I've seen people slop silicone grease all over a multi-prong connector and not have any issues. I do it myself for outside connectors, but for the most part those are only

Hello Michael, As Roland pointed out, it also seem to me to be a matter of signal integrity at high freq. From your video I counted 6 USB interfaces between your PC to your camera (1st hub input

Thanks for the replies Roland, Ray and Steve. I am using TSX. Camera is a FLI Proline 16803 and guider is currently an ASI290. I started using that to replace an SBIG Sti guider which I have used

I use an Atolla 7port USB3.0 powered hub in my observatory, temp now is about 20deg F, no problems. It's cheap, about $25 on Amazon or Ebay. My ASI 1600mm camera has an internal hub adding the

I've never used them on USB connections previously but if there is a way to protect the connections and make sure they don't get moisture or start corroding I am going to do that. This will be in an

Not going to take the mount apart for sure. Thanks for the info about the reflections. Way over my head for sure. Be interesting though to see if my experiment next week shows the same issue

Hi Greg, Which version of the ASCOM driver are you using? Since you are using a GTOCP3 you might want to stick with one of the older ASCOM drivers like 5.21.01. New rate commands were added in the

At the frequencies used in USB3, they begin to act more like light going thru various surfaces. At each connection there is a reflection of the signal just like the air-glass surfaces of a lens. So 2

Hi Roland. I just did a ton of experimenting. Xentex was right. If I simply plug into a usb 2 port the problems go away. Also if I bypass the mount entirely even with a 6 foot long cable, the

A silicone grease can be useful to prevent corrosion of contacts, and if you're plugging and unplugging them a lot or they get jiggled in their sockets it will help reduce wear. I use it all over

I saw a problem like this 2 days ago in 28 ° F. My installation is complex with the Pegasus powerbox V2 installed in front of the plate, 1 USB3 Hub at the output of the mount wiring, 1 active 5m

I would also look for loose equipment, snagged cables, and software settings. It sounds like you image using TSX software so maybe try a simple stand alone program and see what happens without TSX.

P.S. unplugging the keypad won't do a thing one way or other. The keypad does not communicate with the mount unless you push one of the buttons. It is totally silent at all times and does not

Guide at 1x. Going slower will not help. Make sure you have a good calibration run. Remove all backlash compensation, both in the keypad and in the guide software. If using PHD2, you should first use

I have a usually reliable AP1600 mount. It is slewing fine but autoguiding suddenly went wild a little while ago. So normally I get very small guide errors .2 to .6 arc sec guide errors. They suddenly
