SCT Collimation under Adverse Circumstances

SCT Collimation under Adverse Circumstances

Disassembly, transport, and other adjustments to SCTs may result in gross miscollimation, where no "classic doughnut" is available to help in the adjustment process. Bad seeing also results in "bad doughnuts" which make collimation difficult. This article addresses these conditions, and provides some further pointers on SCT collimation.
