[QUOTE=Hans Tucker;1058329]What do you base that on? Have you got any statistics to support this?
I think the more the electrical components and being turned on and off often ,something will eventually give, computers for example .I think using the argument" have you got any statistics to support this ?" is a bit of a put down in an argument. I don't think a ccd camera will outlast a refractor OTA. We still have refractors in use that are 100 years plus. My question was essentially what sort of depreciation would you put on a ccd camera which when it stops working may well be only worth using as a paper weight , whilst most telescope OTA's will continue on if cared for. If you look at the adds for dSLR,s on this forum people are interested in the shutter count before buying !I think we all suspect why.
