Thanks for the added vote for Mr. Brown's project.
I've now ordered a Nema 17 Stepper Motor 17HS13-0404S-PG27 with a 27:1 planetary gearbox. So with the f8 x 200 mm scope this is meant for, that should give me 40-odd steps within the CFZ.
Now we sit back and wait a bit while all these bits and pieces wing their way here from all over the globe.
Obviously I have a bit of reading to do in the meantime.
