This is my first strain wave gear mount. I've spent the last 6 weeks using and becoming accustomed to this mount and it is really good overall. My initial hesitation in buying was based entirely on me being unfamiliar with OnStep, but I went for it anyway and that never became an issue.

I had perfect weather after the 2 day delivery, but

unfortunately I became sick and wasn't able to test under the stars until the next batch of good weather. I did test indoors and the mount performed flawlessly. I use CDC/NINA/PHD2 and these programs all connected to and worked seamlessly with the WD-20 and OnStep programming. .

The only real issue that I couldn't figure out was resolved quickly when I messaged WarpAstron support on Discord. Even though my local time was 8 p. m. , they responded in under one minute and provided me with an explanation of the cause of my problem and a link with detailed instructions on which settings needed to be changed to resolve it. I just don't think there are many mount manufacturers out able to compete with this level of customer service.

Guiding performance is superb. With default PHD2 settings it's very easy to achieve sub arcsecond results. However guiding performance is much better if default settings are not used. There is quite a bit of information out there readily available on this topic. I've played around with guiding settings and achieved the best guiding performance I've ever had from any other mount. That said, I've found that wind does negatively impact guiding performance pretty quickly, even when the wind isn't terribly strong.

For the money, we're buying the hardware and as a bonus we get incredible support for the product. This mount has incredible potential to anyone willing to spend the time to learn the ropes on how to make it perform. I would buy it again without hesitation.

Perfect

Well built. Tight tolerances. Holds my Nikon DSLR firmly, with no tilt, something that cannot be said for every T-ring out there. Recommended.

Fit great and let me mount on the iOptron SkyHunter.

The features we love about our microsccope is the LCD screen and how we have the option to have it run on batteries. We bought it for my ten year old daughter who loves science! It is perfect and easy for her to use!

Mounts with 4 screws and does what you expect it to do.
