Refractors, and especially the apochromatic models, are perfect instruments for astrophotography since they haven't a very long focal length (you can use them for very long exposures also with affordable mounts) and they combine very good performance with easy of use. But many refractors use a focuser that may not be able to adequately support your camera and the accessories used in astrophotography: let's see how you can improve your refractor performance by replacing the standard focuser with ESATTO.

$Replacing your stock focuser? How to check if you can reach focus with ESATTO Do you want to replace your telescope stock focuser with ESATTO? Our robotic focuser is available in different models offering the free aperture, weight load capacity and draw tube travel you need for your telescope and camera. After you choose what version of ESATTO you want to use, the first important thing you have to check is if you can reach focus by replacing your stock focuser with ESATTO. If your telescope has a long focus extraction (usually refractors, Schmidt-Cassegrain, Ritchey-Chretien, etc.) this will also help you to understand if you will need to add extensions. If your telescope has a short focus extraction (usually Newtonians), this will allow you to understand what version of ESATTO will allow you to reach focus.
