Best camera is the one you have: G2 engineering edition
3

There are often threads on this board related to the "best camera is the one you have with you" comment. That proved quite true this weekend, when we realized that my G2+100-300mm lens (typically used for birding) would work as a measuring device on the telescope we're working on. We needed a way to check if the secondary mirror shifted at all when it moved: it turns out that 300mm in m43 is about the right amount to get a good image of the scribe mark in the center of the mirror.

It's being held into the aluminum block by a standard tripod screw, so it's not perfectly stable: takes a few seconds for the system to settle down. Fortunately, I have a Pixel TW-282 wireless remote that I've used for timelapses and long night sky exposures, which works well for this purpose. Hope we can actually measure what we need: viewing the images on the camera suggest it will be fine.

Also critical is the fact that my camera is blue. Such things matter!

Next up: convincing people to buy me an E-M5II, because of course I need one...
