Some folk here in the atmospheric chemistry group are into open-air IR specroscopy. As part of a new setup they are using a Meade 12" SCT. The only part they need is the mirror and cell. So they are trying to seperate the tube from the base section. They have removed all the obvious bolts but the tube doesn't want to detach from the base. They have tried a modicum of force but didn't want to be too heavy-handed.
Has anyone here ever done this? If so, what are they doing wrong?
PS I told them that someone on IIS would certainly know the answer. Please don't embarass me!
