The idea was, if you're going to carry the extra weight, might as well make it useful. You can see it just under the fans in the picture. The bracket swings out so I can get to it. After trying to fabricate the bracket, I found a metal bookend, made a few bends and it was ready to go. I use zip ties and wire guides to fasten and run wires.

Instead of the battery pack supplied with your scope (and mine) I routed it through a fused switch box. The 12V 7amp/h battery sits underneath the box on the side of the scope. -------------------- Meade Lightbridge 12" Deluxe (Modified)SiebertOptics Unitron 4" Alt-Az Unitron 2.4" Alt-Az www.macastro.org.au "A New Eye On the Sky" Post Extras:       John rombi sage Reged: 08/14/05 Posts: 465 Loc: Gods Country Re: Wiring: fan on Dobs [Re: John rombi]       #2612644 - 08/29/08 09:45 PM Attachment (10 downloads) Edit   Reply   Quote Quick Reply   One more........ -------------------- Meade Lightbridge 12" Deluxe (Modified)SiebertOptics Unitron 4" Alt-Az Unitron 2.4" Alt-Az www.macastro.org.au "A New Eye On the Sky" Post Extras:       csa/montana Astro Ambassador Reged: 05/14/05 Posts: 28654 Loc: montana Re: Wiring: fan on Dobs [Re: jskuban]       #2612685 - 08/29/08 10:16 PM Edit   Reply   Quote Quick Reply   Hi Jay, thanks!

Do you have an electrical outlet in your observatory? I dont have a permanent place to view and have to take my telescope for the evening outdoors every time I use it. The distance is short and a 25 foot extension cord is all I need. I don't like buying batteries or recharging them and a 300 MA/120 volt ac adapter works for me. When I'm done I roll up the extension cord and the converter with it. Not real neat and tidy but battery free. -------------------- Kenny "When dealing with a mystery,choose the most unlikely of the likely possibilities"-Sherlock Holmes Edited by KWB (08/30/08 12:42 AM) Post Extras:       csa/montana Astro Ambassador Reged: 05/14/05 Posts: 28654 Loc: montana Re: Wiring: fan on Dobs [Re: KWB]       #2612915 - 08/30/08 02:34 AM Edit   Reply   Quote Quick Reply   I do have several outlets, however, no matter which I would use, the cord would an obstacle for me to trip on. Good idea Kenny, & it looks tidy! Definitely would save on batteries also! -------------------- Carol AstroTech 16" Dob (Thanks ASTRONOMICS!)

All the components can be purchased from an Electronics Store. 1.A Box to put everything into, There are many types and sizes. The choice is yours. 2. A 2AG glass fuse holder (500ma glass fuse) + a switch. 3. 20cm's of hobby wire, to hook up the fuse and switch. -------------------- Meade Lightbridge 12" Deluxe (Modified)SiebertOptics Unitron 4" Alt-Az Unitron 2.4" Alt-Az www.macastro.org.au "A New Eye On the Sky" Post Extras:       csa/montana Astro Ambassador Reged: 05/14/05 Posts: 28654 Loc: montana Re: Wiring: fan on Dobs [Re: John rombi]       #2613280 - 08/30/08 10:53 AM Edit   Reply   Quote Quick Reply   John, thank you! -------------------- Carol AstroTech 16" Dob (Thanks ASTRONOMICS!)
