ESATTO is the new generation robotic focuser that you control by any Windows computer by connecting it to a USB port, or via WiFi by using ESATTO app on your smartphone or tablet with the Virtual HandPad! On the camera side, ESATTO has a M56x0,75 male thread to connect and manually rotate many cameras and accessories by adding the optional adapters with stop rings. 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!
Celestron EdgeHD 800 has a long backfocus, 133mm from the SC thread on the back of the telescope. ESATTO 2" is 67mm thick then you still have 66mm that are more than enough to connect cameras also with accessories for astrophotography (like off axis guiders or filter wheels). When using the Celestron 0.7x focal reducer (that is screwed directly onto the rear thread of the telescope before ESATTO), the backfocus is reduced to 105mm so, after ESATTO, you still have 38mm.
