Excellent. Solid stable and precise. Used reliably with Celestron 9.25 at f/6.3. 1 to 2 arcsec tracking performance in phd2. Requires EQMOD driver.
Excellent expert advice before sale, Item showed up within 1 day of promised date, awaiting clear skies to test but initial indoor testing very good.
I recently upgraded my mount to the SW EQ6-R Pro. This mount is an astrophotography dream. The 44 lb payload is fantastic for my current setup and the built in carry handle makes moving the mount a little easier. With my previous mount I was shooting unguided 45 sec subs with a success rate of only 66%. So far I am achieving 75 sec subs with a 99.5% success rate. Big difference! The belt drive is super quiet and efficient. The EQ6-R Pro is the best value per dollar mount on the market.
Solid, functional mount with all the right capabilities: accepts V and D rails, easy compatibility with ASIAIR controller, 45 pound loading for most set-ups, heavy but moveable for an elder imager, pretty too.
I ordered an EQ6-R from OPT. The process was easy and I received a receipt via email. The Mount was delivered on the date expected and in good condition. I used the manual to guide my set up process and everything worked exactly as expected. I am quite satisfied with this purchase and will continue buying from OPT.
This is the newest EQ6R-PRO with USB on the hand controller and the mount head. It's heavy but manageable with the new handle. Best I've ever owned.
