I have been using an Optricon for the last 2 years but have been offered a 6month old Zeiss 85 straight diascope for £500. Am I getting a bargain ? How different is using a straight one to an angled one (which Im quite comfortable with) ? I know nothing about Zeiss scopes so also want to know the best camera for digiscoping with a Zeiss 85. Many thanks in anticipation |;|
