Doc Posted August 11, 2015 Share Posted August 11, 2015 (edited) Have finally sorted out my dew set up in time for Kelling. It consists of a 12v 8ah Gel battery which should last most of the night and will be charged during the day. Thinking about buying a second battery as well. I needed this size as it fits into the dovetail clamp opposite the one I use for the scope. The good thing about Gel Batteries is that can be run upside down, or on their side it doesn't matter unlike normal batteries. This runs down to a dew controller from R-Sky of Russia, I've used this firm before, they make very good quality stuff at very reasonable prices. Then this runs to a dew strap for the lens cell, a dual finder dew strap for the Baader Skysurfer, and finally a large eyepiece strap for large 2" eyepiec es simailar to the Televue Delos and Nagler range. So just another battery and a battery charger to buy as a gel battery needs a special type of charger. Edited August 11, 2015 by Doc Link to comment Share on other sites More sharing options...
Tweedledee Posted August 11, 2015 Share Posted August 11, 2015 (edited) Brilliant. Love the counterbalance. Edited August 11, 2015 by Tweedledee Link to comment Share on other sites More sharing options...
Smithysteve Posted August 11, 2015 Share Posted August 11, 2015 Nice one Mick, that looks like good solution. Have you thought about a dry run, testing the whole dew setup during the day, to see how long your 12v bat will last with all heaters attached, also checking the heat on the straps is consistent and bat voltage etc at intervals. Cheers! Link to comment Share on other sites More sharing options...
Brantuk Posted August 11, 2015 Share Posted August 11, 2015 Counterbalancing and dew control at the same time - excellent idea! I'd be tempted to put a couple of long cable ties around the battery and mount shoe just in case the clamp loosens as the temperature drops and metal shrinks. At least if it did come off, the battery wouldn't yank everything it's attached to. Superb solution though. Link to comment Share on other sites More sharing options...

Doc Posted August 11, 2015 Author Share Posted August 11, 2015 Thanks guys. Yes Stephen I'm going to do that when I get the battery charger. I've tried it and the straps all get warm, but haven't tested how long it lasts for but It's only drawing 1.4ah so it should last about 5 hours. So if I get a spare battery should be sorted.

Tweedledee Posted August 13, 2015 Share Posted August 13, 2015 It says 20 to 40 days delivery on their website. How long did yours take from order to delivery? Link to comment Share on other sites More sharing options...
Doc Posted August 13, 2015 Author Share Posted August 13, 2015 About 10 days Pete. I did query the time before I ordered and he said he would package it as soon as I had paid for it, which he did and I got a tracking number to prove it. Russian Post are pretty slow, but then it's cheap and you pay no tax so I went for it. Link to comment Share on other sites More sharing options...
Tweedledee Posted August 13, 2015 Share Posted August 13, 2015 Thanks Mick, they certainly do look good for the price, and it seems delivery time need not be too long. I like the finder heater, with eyepiece and objective heaters on one cable and the neat and compact single channel controller. It all looks just right on a 120mm scope Link to comment Share on other sites More sharing options...
Doc Posted August 13, 2015 Author Share Posted August 13, 2015 They do feel very well made especially the large 2" eyepiece strap. Next time we meet I'll show them to you, I think you will be impressed. Link to comment Share on other sites More sharing options...
