A few words about cooled camera weight.
I worked out the weight of my colour cold finger 450D today, it was 1.5kg complete: With T-Adaptor, UV/IR Filter, and bayonet ring, cold finger assembly including TEC, Deep Cool 200 heatsink/fan combo, the carbon fibre support bracket, battery eliminator, all wiring, insulation and Argon bag. This is lighter than I expected.
The spec sheet for the 450D lists the body weight as 475gms without battery. The weight of the Deep Cool heatsink/fan is 400gms.
Out of interest I also weighed the new Coolmaster/Noctua fan combo that I have assembled for the mono camera, and it came in at 450gms; not much difference between this 120mm solution and the 92mm Deep Cool. Probably will not be a factor on the focuser.
I'd be interested in getting some other weights from people doing these mods so that we can baseline it.
