Finally got some time to try to figure out a solution to the cable madness for a mobile astrophotography off-the-shelf Sky-Watcher EQ-6 Mount... 

 

My goal was to make it so I only had 2 cables to connect from my laptop / observation station.

 

  • 120v power
  • CAT 5 - USB over CAT 5 cable

 

This is a design I have been working on during my week of vacation. My first test print is is printing now - though the print time is pretty crazy @ 55 hours.

Items inside the box.

 

Everything else should be self contained within the mount and with short connections to the telescope. The final design requires 2 power connections - one for the 12v power supply and another for a small power strip inside the box.

 

The contents inside the box include:

  • 30A  12v DC Power Supply (can operate at 12-13.8v)
  • RIGRunner 4004U Anderson Powerpole distribution station - powers the Sky-Watcher Mount and Dew Heater (and maybe the Moonlite Focuser?)
  • USB 50m Cat 5 extender receiver
  • Moonlite Focuser controller (is the only thing that is velcro'd on for easy hand control)
  • Thousand Oaks Optical Dew Heater Controller
  • Anker 7 Port USB Hub

 

Items that will be controlled by USB:

  • Sky-Watcher AZ-EQ 6 GT
  • ASI1600mm-c imaging camera
  • ASI-120mm-s guiding camera
  • ZWO EFW Filter Wheel
  • Moonlite Focuser

 

All USB items are connected via a USB hub in the box. USB to mount is via a 50m USB over CAT-5 cable run - which allows a lot of flexibility for laptop station placement. This is a mobile station.

Hi

Nice project! Seems very compact and easy to use.

I made something similar that shared in the following thread:
https://r.tapatalk.c...link_source=app

In the original article I putted information about calculating cable gauges and other important calculations needed for a project like yours. Maybe can be useful for you (if you didn't already calculated).

This looks great!

 

My only concern would be that the power supply can get adequate ventilation for cooling.

Here is another option to deal with cables. I just found this and purchased it -- not yet installed. Not cheap but it provides a single small-box hub for

 

- Dew heater power for two zones (it is also a dew heater controller)

- USB 3.0 hub including 5V power supply for four connections

- 12v DC power for four connections

 

Seems like a nice item.

Very timely. I am starting today to find a way to get things under control. Very nice ideas here.

That is a cool little box. If only it had 6 USB outlets instead of 4 - as I currently have 5 items that need USB. I see they also have a 6 port hub - but whoa - the two together is ~$500

 

I also haven't been able to find a USB-3 over CAT5 solution - my USB over CAT5 works great, but is only USB2.

There are several USB - CAT5 or Cat 6 extenders available (google it) but the cost is frightening!  Unless you are considering selling a kidney I'd stick with 2.0 over Cat5.
