Uploaded March 2022 | Updated September 2026, 15 hours ago

Officina Stellare RiDK 400 f7 is the modified Dall-Kirkham telescope with 400mm diameter and 2800mm focal length that provides large corrected image circle and long backfocus, together with the high load capacity ESATTO 4" robotic focuser! Thanks to 298mm backfocus from telescope rear cell, you still have 198.5mm focus extraction after the focuser, so you are able to install any camera also with many accessories like off-axis guider, filter wheel, and even adaptive optics.

$SESTO SENSO vs ESATTO – Which motorized focusing system is right for your telescope A perfect focus is essential to get the most out of your telescope. That’s why at PrimaLuceLab, we developed a complete line of motorized focusing systems designed to make focusing easier and more accurate for any telescope. In this video, Filippo Bradaschia, co-founder and President of PrimaLuceLab, explains the differences between SESTO SENSO 3 — our focusing motor that uses your telescope’s existing focuser — and ESATTO, our complete robotic focuser that entirely replaces your telescope’s stock focuser. You’ll learn: 🌌 The main differences between SESTO SENSO 3 and ESATTO ⚙️ When to use a focusing motor vs a robotic focuser 🔩 How SESTO SENSO 3 transforms your manual focuser into a motorized one 🚀 Why ESATTO provides the ultimate precision and load capacity for astrophotography 💡 Which model is best for different telescopes like refractors, Newtonians, and Schmidt-Cassegrains Whether you’re starting with astrophotography or upgrading to a professional system, this guide will help you choose the right focusing solution for your telescope. 👉 Learn more about each model here: https://www.primalucelab.com/focusers/$
