Here are a few mods I've made to my 12" Lightbridge.
1. first photo is a 12v SLA battery, wired up to a control box. The box is doubled fused for the fan and the switched pot. The pot controls the eyepiece heater and a heater for a future optical finder.
The wiring runs inside the truss and then is held in place with velcro. The heater is also homemade.
The circuit board needed to contol the heaters was put together by a friend of mine.
I hope this helps other LB owners who would like to head down this road.
Apart from the batteries that are about $25 each, the remainder of the parts cost about $40.
The two cases carry my eyepieces 26mm Meade 2" QX, Widescan 111, 16mm 84AFOV, 24mm Ultima, 17mm Celstron Plossl and Meade Shorty Barlow + assorted filters.
The second case has two SLA batteries, Orion Collimator and my red headlight torch.
I put together the chart table from plumbing supplies and 4 ply and a healthy coating of Marine varnish.
The denver chair was put togther by the same friend that built the circuit board for me. It all fits neatly into my Laser along with my freezer suit and nibblies to keep up the energy on those loooong observing sessions.
