Filter Wheel Mod
Rebuild with smaller (this time bipolar) stepper. Better torque. IR sensor mounting improved.
This shows stepping through filters with accurate stop points.
A small "L" shaped piece of aluminum marks the end of position 4 and if sync is selected, will stop at position 1 (Luminance filter).
Revised drive mechanism and added reflectance sensor (Pololu QT-R1A) now driven by arduino scopefocus unit w/ second stepper driver. The stepper turns until the filter is in the proper position, marked by a small piece of white tape.
Here's a screenshot from the scopefocus filter control tab....progress!
--Added button to select equal number of subs for each filter.
--Saves subs w/ filter type as filename.
--Standard filter selections populates filter dropdowns w/ appropriate filters
--Two different Darks available
--Flats, single or after every filter change(see AutoFlat page for addt details)
--Auto Sync for filter wheel, advances wheel until position 1 marker found.
