Product Description

PrimaLuceLab ESATTO 2" Robotic Microfocuser

ESATTO is the new generation robotic focuser for telescopes designed by PrimaLuceLab to fulfill the needs of the most demanding astrophotographer! Now you can remove the stock focuser from your telescope and, thanks to a complete series of specifically designed adapters (available separately), you can easily connect ESATTO to many different telescopes! ESATTO can be controlled by any Windows computer by connecting it to a USB port, or you can control it via WiFi by using ESATTO app on your smartphone or tablet and use the Virtual HandPad! On the camera side, ESATTO has a T2 (M42x0,75) and M56x0,75 male threads with stop ring to connect and manually rotate your cameras as well as adapters for M48, M57 and 2" visual backs. The 2” version of the ESATTO 2" has a depth of 67mm, it has 15mm of focuser tube travel, a 5kg payload capacity and an incredible resolution of 0,04 micron per step (and this is why we call it ESATTO)! And you can also expand ESATTO features by adding the ARCO robotic camera rotator!

Wanting to change your stock focuser because it isn’t sturdy enough and lacks precision? Do you want to improve the internal focuser of your SCT telescope? ESATTO is the next generation robotic focuser for telescopes, specifically designed for astrophotography but, thanks to specific technologies developed by PrimaLuceLab, also works extremely well for visual use. Forget about external controllers and cumbersome hand pads - ESATTO is the ALL-IN-ONE focuser that has all the features you’ve dreamed of in a compact, sturdy focuser design.
