Vernier calipers for focus setting?
Hi All,
Has anyone here tried using a set of vernier calipers to set their focus for imaging?
May not be able to set focus precisely, but should be able to get a pretty good starting point if you have a measurement between two reference points from a previous imaging session. I guess that SCT's will have no real reference surfaces so it would not work with them.
Any input appreciated.
Regards,
David.
