Homeyer filterwheel with four adaptors.
-- SCT male threads to F.W.
-- Male t-thread ring to F.W.
-- 1-inch (25mm) extension
-- 2-inch push in adaptor (fit's JIMI focuser, others)
The F.W. can be either manually controlled or computer controlled via Astroart. (There may be other computer programs that will control it -- I don't know.)
For manual control, several built in LEDs indicate the current filter color.
Will run on 12v but likes 15v or higher in cold weather. I have a 15v AC adaptor (not shown) which I will include.
New price is $475 + about $25 or more each for the adaptors + $20 or so shipping. (Homeyer has other adaptors or will make custom ones for a very reasonable price.)
Selling for $400 shipped CONUS.
(You save from $100 to $150 depending up which adaptor you need, and take my word for it: It's always handy to have a wide range of adaptors to try out different configurations.)
