I was looking for a motorized focuser for my SCT about a year ago
Products from JMI came to mind first up but I was put off by a small number of user comments to quality control issues . In the end it came down to either a unit from Moonlite or Starlight Instruments, both had very positive vibes from forums and message boards I visited .From memory at that time Starlight Instruments didn't have a motorized version for a SCT , Moonlite had just released a range of focusers for SCT's both manual and motorized.
I went with the Moonlite with the motorized option, unfortunately when I received it the thread was to tight for the focuser to go the full travel on the back of my scope. Inconvenient and frustrating yep , but credit to Ron Newman , he was genuinely upset about putting me out and corrected the problem pronto plus during the whole purchase he was extremely good to deal with and very prompt with return emails {he must live on the net
}. Anyway the focuser works great looks good and I'm very pleased with it , bear in mind I still have to use the coarse focuser on my LX200 when I swap eyepieces of varying focal length.The only let down though is the appearance of the motorized controller, it is one ugly contraption in comparison to the focuser
but it does the job and is easy to use , great range of speeds and a great aid for planetary imaging. Ron also added a PC interface for the inconvenience , tried it a couple of times before I passed it over to another moonlite owner , seemed to work well
