show us your.... cable setup?!

26 posts in this topic

Hi sgl community!

I am struggling with all the cables connecting my gear: 2 cables for the guide cam, 2 cables for my primary camera, 3 cables for the mount, usb hub power and connection ... any and all pictures on how you manage the cables would be welcomed!

I will post a picture - once I have finished sorting my cables out. I did have them done previously but for various reaons had to beak them down again.

What I use are Self Adhesive cable tie mounts and cable ties as well as a powered USB hub, which means I have only one cable going from the laptop to the mount / scope

Hello uplooker that is a hell of a good idea! i could clean up the wiring mess in my office as well with those.

Best to use a cable sheath rather than cable-tie the bundle of cables together - it's more flexible. For myself I run all the signal and power cables to an attachment point near the centre of the DEC axis, then leave a loop which is long enough to allow for a meridian flip, and a second attachment point on the RA axis housing. That leaves just a couple of dewstrap cables which plug into the controller which is Velcro'd onto the DEC housing. There is no significant weight of cables pulling on the OTA, and to remove the scope I just coil the cable sheath around the focuser and it comes off in one:

If I showed you my cables I'd get thrown off SGL! In my defence I can say that they work and that I know which USB cable is which at both ends because my mess is a labelled mess. The dual rig has eleven cables. It also has one spare 12 volt power supply and a spare of both kinds of USB retained in the loom. You don't get me, Mr USB!

:Dlly

PS: A while back I was asked why I didn't use a HiTech Astro box on the dual rig to reduce the cable count. That very day (I kid you not!) there was a FLO announcement about recalls of some of those units. And there's your answer. When it's 'broke' I'll fix it. This game is complicated enough without trying to simplify it... :evil4:

I was just following Per's excellent advice on cable arrangement :)  There are pictures and an explanation from him somewhere on here (and from what I recall he never had anything good to say about Olly's cables either!)

Ah me, it was another of our running gags. However, he did concede that he needed to label them since there was no way of knowing which was which at either end of his superbly organized loom. My labels and Per's neatness really ought to be the way. However, I think having a spare USB in the loom is a good idea. They do suffer random failure. I was very glad of mine last month.

Originally I'd used tape and cable ties to bind the cables into a loom so swapping cables meant an hour of undoing all this work. Eventually I ended up with two redundant cables in the loom because I simply couldn't be bothered undoing it all to get them out!  So after this incremental process of adding more cables and more tape the thing was so stiff you could have attached a brush head to the end and cleaned the patio with it :)  I saw Per's nylon braided sleave and thought 'Aha!' brilliant idea - it remains flexible and yet easy to swap/add/remove cables (I chose the zipped version). Note also Per's method of routing and securing the loom, prior to this (using my G11 with a mess of cables) I would worry every time a meridian flip was needed that a cable would snag and I would have to go outside and watch it to ensure everything was OK. Now I don't even think about it. :)

This is my current cable setup:

LX90_Astro_CAT.jpg

It's something I've tweaked, changed and sworn about for at least 10 years and really I think this is the first time I'm almost happy with things :) The LX90 having the main power socket rotate with the base has never helped matters.

I built a powerpanel that is attached to the OTA. I only have 2 cables running from the mount (power, data)

The box is permanently attached and the cables stay plugged in when I store the scope. I cut down the time it takes me to setup the whole thing, from opening the OTA bag to powering all the devices, to less than 2 minutes :)

Here is a picture of the box attached without all the cable and protective case

ProjectBox4.JPG

Here is a video of the box in action with all cables and protective case

it works pretty well, no balancing issue as it is very light.

Olly, 

Apologies for resurrecting this thread, but what do you use for your labeling? I have previously use a Dymo label printer, but they don't stick to the cables well, so they just kind of flap around.

Just paper wrapped in Sellotape. That's the south of France for you!

Not really an option in soggy Gloucestershire. The first time the dew comes up they will all get ruined. Time to see what google can recommend...

Before and after shots of my cabling attempt today. It wasn't quite as bad as the before shot, as the two camera cables were cable-tied together, and the two dew heater cables were cable tied together; but it was all still hanging down (*looks for hangs-head-in-shame emoticon)

I have used a length of 30mm wide nylon cable sheathe. I could have gone with narrower, but 30mm wide meant I could get the cables down one by one with no problems. the camera and dew-heater cables are attached to the horizontal dovetail bar with a Velcro tie. Then the nylon sheath is attached to the main part of the mount by another Velcro tie slipped under a larger Velcro strap fastened around the mount head (I did not want to put any kind of permanent fixture onto the mount itself). The end of the nylon sheath is then attached to a leg with a velcro strap where the dew heater controller is attached with (you've guessed it) another velcro strap.

The advantage of all of the velcro straps is that I can remove the whole cabling loom easily when I need to pack everything away.

This is what my cables look like 99% of the time. About the only advantage of setting up and taking down each session......:D

      Now when I have APT that control the camera it could be a bit boring when waiting. Maybe I could do some visual observations when the camera are doing automatic photographing?
      I'm not a big fan of visual observation, but I recently bought a big 25x100mm binoculars and think it could be fun to have. It's very heavy and could not be handheld, I have to built a mount for it. This is something new to me so I reading forums and get ideas and figure out my own solution to it. As a first part I bought a caster wheel to have as a roller bearing. I will mount that on my second pier.
      If you find it interesting you can see more details here and follow my project:

      Hi,
      First post - so I hope I'm putting this in the right place. I wonder if anyone can help? I've got an EQ3 synscan mount which sits on top of a concrete pillar. Despite the Rigid Pillar and good Polar alignment I get terrible Goto's and Tracking. I wonder if upgrading to an EQ5 might solve some of the problems. It seems, from the reviews, to be a much more accurate mechanism. But if I did that is there any way I could buy the basic EQ5 and use my current EQ3 Synscan motors/handset with it. Buying the whole EQ5 with synscan is horribly expensive, and having already got the synscan unit would seem a waste.

      Hi all,
      Any help and advice you can provide me on this subject would be greatly appreciated. I'm not new to Astronomy but very new to Astrophotography and currently in the process of researching the equipment to start capturing photo's using my skills of being able to find already,
      Currently I have a Skywatcher EvoStar 80ED and looking at upgrading to the Esprit 80 more personal preference but I am unsure if my Current EQ1 would do the Job for this I've been searching around but can't find too much info. I've looked at the Weighs of the Esprit and if I've looked correctly I think my EQ1 would struggle  to support the weigh.
       
      Kind regards
      Sharkey

      This is a nice Vixen GP mount in very good used condition. The mount itself is xcellent cosmetically, and turn smoothly with no unevenness. The only real criticism you could level at it is the fact that the counterweight and bar have been resprayed in a dull metallic colourful, looks ok and works perfectly well. It has one small counterweight.
      It has short slow motion controls (which of course could be replaced with long flexi ones), it does not have a polar scope. I would say it is highly suitable for visual use where you just want tracking with minimal setup time.
      I can supply it with the original short wooden tripod included for £150, or a taller aluminium matching Vixen tripod for £175. Open to reasonable offers.
      Payment by PayPal fees paid or bank transfer. Pickup is easier but I can ship it at cost.
      Thanks,
      Stu

      Hi,
      I was asked on a Swedish forum to put an "Astronomical Dictionary" on my homepage. I have made a test page in an easy form. Astronomical related words linked to wikipedia.
      It aims to the beginners in astronomy so it should not be too complicated words.
      http://astrofriend.eu/astronomy/astronomical-dictionary/astronomical-dictionary.html
      Let me know if it's useful and and I shall add more words.
