Yes, that is correct. The purpose of the calculations is to determine the correct stepper motor choice. You have found a PG27 is not suited. When you redo the math for a PG5 stepper motor, well you get the desired result,
spreadsheet attached, first tab = pg27, second tab =pg5
Telescope: Skywatcher evostar 100ed f/9
Focuser equip: nema 17 pg27 solderless solution with nano and drv8825, direct connection to focuser axle
12mm per full revolution of my focuser
I was doing the math for the cfz and stuff it says to get to 10 steps
(9 * 9 * 2.2)/((12 * 1000)/(5370)) = 80 steps within cfz.
Is this ok? It's way more than 10.
