Fitting SW accu motor to 10:1 Crayford
I use the SW accufocus motors on almost all of my gear - cheap and does the job well. I have these focuser motors on my ED80 for Ha solar imaging and the C11 for spectroscopy...
Just before I left Belgium I managed to aquire a Baader Herschel Wedge and a TS 102 f11 Achromat.
The TS102 has been converted to a modded PST as well.
This scope has the generic 10:1 Crayford and I needed a fine focus control for solar imaging.
The attached images show the set-up:
Based on the Std SW/Orion focuser motor...
I already had a 28 tooth wheel and 80 tooth belt from another project (!!)
I measured the "gap" below the Crayford body as 9mm and found a piece of MDF and a 1.6mm aluminium plate which stacked up.
By removing the two small M3 screws from the base of the Crayford and drilling a 6mm diameter hole ( to clear the locking screw) I managed to come up with a pretty compact solution.
Pretty self evident, but works very, very well for fine focusing with the DMK camera.
Any questions let me know.
