Quote:how could it damage your mount if you are using the proper fuses inside the cig adapter? Won't pull enough current?
"Considered as a collector of rare and precious things, the amateur astronomer has a great advantage over amateurs in other fields ... the amateur astronomer has access at all times to the original objects of his study; the masterworks of the heavens belong to him as much as to the great observatories of the world. And there is no privilege like that of being allowed to stand in the presence of the original." --Robert Burnham Jr, Burnham's Celestial Handbook

Quote: The only problem I see is the dew heaters could drain the battery so that the voltage becomes too low for reliable mount operation. I would be surprised to see voltage spikes measured across the battery terminals . If powering a goto mount,dew heaters,and active cooled cameras a large capacity battery pack is a very good idea.Some of the booster packs have only a 7AH battery inside ,better is one with a 15AH or 17AH .It will cost more and weigh more but will be more reliable.

“I am the only person to ever ace a 1951 USAF resolution test. My 'to observe' list says 'done'. I do not use charts or atlases when I starhop; men do not use maps. One of my sketches won an SBIG deep sky imaging contest. I am the life of star parties I have never attended. I never say anything looks like a faint fuzzy - not even a faint fuzzy. Pilots aim green laser pointers at me. Don Pensack proofreads my CN forum posts.” - The Most Interesting Astronomer in the Universe
Quote:I always use a single battery to run my mount (CG5, Atlas, CGE, Nexstar SE) and dew controller. Never an issue in decades. I use a splitter as you describe. I also use quality batteries (Optima deep cycle blue tops).- Jim

Quote:Ok, I just sent him another email so hopefully I'll get some explaination on it soon. Actually I was hoping to hear what I have so far (that it is fine to use 1 battery). It sure would make things easier on me. I'm also hoping Uncle Rod will chime in with his thoughts.

Quote:Still, I run the scope off a different battery to avoid _potential_ problems and to keep the battery up enough to run the go-to scope reliably. Many go-to mount problems caused by low voltage there are...

Quote:There is no "Inductance" in a splitter. Inductance takes a coil, and these devices do not use coils. They simply have buss bars to distrubute the voltage to the different sockets.
Quote:Hmmm...for some reason the pic didnt come up. I'll try again. I can easily wire in another plug next to the one I already have if the splitter is what he's saying could cause the problem. From what I understand he's saying a 12v battery IS regulated unless something else is plugged into the same socket?
