I get asked a lot to compare our products vs another manufactured product. As an employee of Starlight Instruments which is the manufacture of the Feather Touch focusers, of course I am a little biased. For this reason I contacted 2 astronomers and let them test and compare the Focuser Boss II with PDMS motor and the Robo Focus. Below are their comments:
The Posi Drive has
- Low backlash makes for more repeatable focuser positions, which leads to more accurate autofocus.
- Higher quality components.
- More torque/carrying capacity means less slippage with heavy cameras or high targets… see #1 for implications.
- Robofocus is still a 9-pin serial solution, if you want USB/Ethernet/WiFi they need the Focuser Boss II
Your primary market was making a better focuser, but the automation solutions weren’t the same quality as your focuser , so you designed an electronics solution to go with a motorized option which now gives the astronomer the best of both worlds.
Below is the comment from the 2nd astronomer:
No slipping! Smoother operation. Easier to disengage for visual or manual focus. No serial cable or adapter to use. Better control software.
And a big plus particularly is the built in temperature readout and temperature compensation which is very useful for the slow to cool telescopes.
I currently use the Posi on a TEC140, AT 10” RC, and soon my Epsilon 160. All which had the robofocus before.
If interested, please feel free to contact me regarding other manufactured comparisons to products from Starlight Instruments.
Starlight Instruments is proud to announce the release of another adapter. This adapter is for our FTF32XX series focuser which is a True 3″ focuser in which it will accommodate a 3″ accessory. This adapter will allow you to upgrade your ES127CF with sliding dew shield with a True 3″ Feather Touch focuser which will allow you to use 3″ viewing accessories or with our reducer you can also use 2″ viewing accessories.
Starlight Instruments is proud to announce that we will be attending the Okie-Tex Star Party. This event is from September 24th through October 2nd.
Jon the owner of Starlight Instruments will be at attending and will have a booth for astronomers to look at and test our new products.
We are in the process of machining a brand new focuser and hope to have this focuser completed in time for the show.
For more information please contact us or see Jon at this event.
Starlight Instruments is proud to announce the release of our Posi Drive motor (PDMS) for the Sky Watcher Esprit telescopes as well as the Takahashi dual speed focusers.
The PDMS motors were designed to be controlled from the Focuser Boss II digital kit. In testing, the PDMS is able to lift in excess of 56 pounds. This motor attaches to the pinion shaft which eliminates slip from the reduction assembly. This motor will allow you to have repeatability which will allow you more time to view and less time being frustrated.
Below are the links from the website.
