Yeah and minature airconditioned cool box. It will be important to match the internal with the external temp fall. One of my concerns would be that when the OTA is removed from the box it will becoming from a low humidity environment and moisture in the air will instantly start to condense on the OTA. There needs to be someway to prevent the external air from getting into the OTA. Condensation on the outside of the corrector plate isn't a prob, getting it on the inside would be a different story. Maybe that dust/humidity filter would work in that situation.
Few things to think about to solve this little problem
