I've enjoyed my setup in my observatory for 3 years but recently I am experiencing a few issues which I think are all power related. I control two scopes and the usual accessories (filter wheels, imaging cameras, guide cameras, auto-focusers, dew heater, etc) through power coming from my house which is regulated via a 12 VDC (13.8 nominal V) box on the pier. This runs up to the both the AP mount CP-4 control box and my C11. On the C11, I have a Linx power panel with Anderson connectors and a powered 3.0 hub for accessories to receive power. The hub USB cable runs down through the mount to the laptop. All has worked well for 3 years but suddenly, I am noticing a few hiccups like a filter wheel sometimes not working and most recently a view on my PHD2 screen of a snowy/grainy image which flickers to the normal black one would expect- never seeing any stars.
With this background, I was curious what type of HUBS and other accessory connection devices (power panels) folks have found to be very good. For example, I noticed the Acroname hub but the price is eye popping. However, if it is the best, I'll certainly get it.
