How do You power Your mount ?
      #3031914 - 04/08/09 11:58 AM

Hello, I have been using the "Blue Wave MC Power" power supply BW 1205z which used 230-220 Volts IN and gave 13.8-12 Volts OUT. The great thing about it was that it only had a few interfaces so You didn't have to worry which one to use.
I have switched to the larger PentaFlex 12V PowerTank 7AH which has 2 interfaces to put the power stick (usable in a car) into... Which one to use, the - Minus (Left) or the + Plus (Right) ?




In the photo above I've connected it to the - Minus (Left)

I use one of these for remote locations. Kipor Generator
It's light, quiet and cheap. I picked one up at Harbor Freight for $150.

My first choice is always to use 110 volt current, often available at many viewing locations. Where it's not available, the next best thing is battery power. I use 17 AH units and ALWAYS make sure they are completely charged before leaving home. A poorly charged battery makes goto units act very strangely.

I use a deepcycle marine battery with a 150 watt power inverter. Have powered my set up for over 5 hours with battery power left even when the temp was 15 deg F. I power my Atlas EQ-G w/EQMOD, Atik 16IC-S imaging camera, Dell laptop, Atik 16IC guide camera, FCUSB,GPUSP,Atik USB filter wheel, 7port USB hub and a small portable radio. Here is a pic of my setup, this was taken at home but its the same set up I use in the field. http://i669.photobucket.com/albums/vv60/Fortune07_photos/North-Country-Observatory.jpg

What makes you think they are different? Seems like that would be really unlikely.

After the original power pack stopped working and I found out there was no way to replace the battery, I decided to build my own so I could easily switch out the battery when I needed to. Right now it contains a 12 volt 12 amp-hr deep cycle batter. I use the charger from the original.

Well Mike, because these are labeled - and + underneath each socket...



So which one to use...

Those - & + charge indications might ONLY be valid when charging the PowerTank from a car battery ?

I have the Celestron version of your power pack. Powering 2 scopes, I got five hours out of it. I think with a dew heater it might last 3-4 hours. I keep the charger in the EP case. So I can charge it if an electrical outlet is available.

A 100 amp hour deep cycle marine battery. Oh yeah, and I also have a 7 amp hour & 17 amp hour power tanks that I'll bring if I go on camping trips. I never want to run out of power when I'm under dark skies...

I believe you are misreading the info there, it's indicating which polarity the outer ring is and which the center contact is and applies to both sockets. You can see a similar graphic on the single smaller output jack to the left.

They could have done a little better job with their depiction, certainly, since there's obviously a potential for confusion.

O.K.Mike that makes 100% sense

The -/+ indications isn't talking about which port is positive/negative. It is talking about how each of the ports are setup. In this case, the tip is expected to be positive, and the shell negative, with a potential of 12V. So if you are building your own power connector, you have to build it such that the tip is positive, the shell is negative, and that you are assuming 12V as the potential between the two terminals in your plug.

Hudson Yak,

Totally agree, both left and right plugs are hooked up the same way. The picture is telling you that the Male part of the cigarete lighter adapter is positive and the 2 sides contacts are negative.

Those little markings are not identifying the two power outlets differently. It is a graphic that tells you that either outlet is configured as Negative (-) on the outside and Positive (+) on the inner tip. It is one graphic or picture that applies to both outlets ... they just put it in a bad place so it looks like it is referring to each outlet separately.

At home I use two 12v 5amp power supplies with a 3 to 1 outlet splitter on one supply ... so I have 4 12v outlets available (mount, dew controller, camera, spare). When I'm in the field I simply replace the two AC/DC power supplies with two 12v 17a/hour batteries, all the cabling is the same.

When my Celestron power tank battery "bit the dust" after minimal use, I threw away the battery and strapped on a "power scooter" 36AH battery and tied it into the external connections on the power tank. Work likes a charm...much better than the original 7AH.
(Celestron offered to replace the unit but the shipping was around $15 ...the scooter battery was free ...and has a nice carry handle)

Don't mean to hijack the thread but all these posts prompt me to ask - What am I doing wrong?
85A/hr deep cycle marine battery running a 400W inverter with AC adapter for an Atlas an AC adapter for a Dell laptop and 2 (USB) DSI's - all through the inverter.
Didn't seem to last an evening much less 8 hours - inverter shut down at 11.?V. Is the inverter an issue?

P.S. WiFi is active but does it make *that* much difference?
