Look familiar?

Tragedy Happens.

We've seen 

enough.

​False zero position, software failure, human errors... These could all lead to collision between your gear and your supporting legs, damaging your beloved equipment, wasting your valuable observing time.

Using limit could prevent this, in most scenarios. Existing products in the market use FRAM limits, which in some cases, could go wrong. FRAM relies on ACCURATE zero position to function as designed. 

In cases where zero position is inaccurate, FRAM limit might not be triggered as expected. â€‹

Here in Clearsky, we are proud to introduce:

The World's first Mechanical Limit Solution

Our patented mechanical limit design uses industrail-level sensors, together with mechanical interior designs, ensures overwhelmingly-high reliability. This will be the ideal final vault for equipment protection.

One more thing...

Here in Clearsky, we believe our passion for astronomy should reach everyone. A good design and a secure protection should not be a privilege. Thus, we embedded mechanical limit to every ST17, ST17R, ST20 and ST25 PRO. High reliability with a decent price, we hope you'll love the ST series
