I have a co-author of HR coma and I would like you to clarify a question.
I have read the instructions for the 1st configuration of the coma corrector and on the one hand they say that you have to set the eleicoidal focuser at 13.5mm from the beginning of the scale and on the other hand it says that it is as seen in the image.
In the image it can be seen perfectly that from the beginning of the millimeter scale there are 18.5mm.
Can you clarify where those 13.5mm are from?
From the beginning of the scale or start counting 13.5mm from 5mm.?
If anyone has this coma corrector and can help me I would appreciate it.
