This Newton QUATTRO 254/1000 f3.9 by SkyWatcher offers a large 254mm diameter with 1000mm focal length: thanks to the fast f/3.9 focal ratio and to the compatibility with the very good optional coma corrector, it's great for astrophotography. Thanks to the not too high weight (11 kg), this Newton telescope can be used also on EQ6 type mounts. The Newton QUATTRO 254/1000 f3.9 by SkyWatcher allows you to record the weakest details of deep-sky objects like galaxies, nebulae and star clusters but it can also be used for visual application. In fact, thanks to the included SESTO SENSO 2, if you want to use it to observe the objects in the sky you can precisely control the focuser position without touching the telescope or even without a computer thanks to the included Virtual HandPad. It includes 50,8mm Crayford focuser with 1:10 micro reduction, SESTO SENSO 2 robotic focusing motor, 8x50 optical finder, support rings with Vixen type dovetail bar. 3 years of warranty on the optical tube!
This special version of the SkyWatcher Newton QUATTRO 254/1000 f3.9 adds SESTO SENSO 2 - The highly accurate, advanced, vibration free, robotic focusing motor for your telescope! Connect it to the USB port of your EAGLE or Windows® computer to electronically control focus while still allowing you to manually move your focuser by hand if needed. If you don’t want to focus using a computer, you can connect wirelessly from any smartphone or tablet using the integrated Virtual HandPad via the built-in Wifi network in the SESTO SENSO 2! Thanks to the Self Centering Clamp technology (SCC), SESTO SENSO 2 can be installed on most focusers without the need of external brackets. The supplied FOCUS Manager software and ASCOM driver allow easy configuration of the many advanced features of SESTO SENSO 2. Thanks to the precisely controlled motor with integrated electronics, SESTO SENSO 2 achieves incredible precision of just 0.7 microns. And you can also expand SESTO SENSO 2 features by adding the ARCO robotic camera rotator!
SkyWatcher Newton QUATTRO 254/1000 f3.9 with SESTO SENSO and the following optional accessories: Losmandy style 350mm PLUS dovetail bar (below and above the tube) and EAGLE with guide scope in parallel (above the telescope).
Thanks to the use of SESTO SENSO 2, you can use the SkyWatcher QUATTRO 254/1000 f3.9 both for visual use (with the SESTO SENSO 2 Virtual Hand Pad you can move the focuser even without a computer and without touching the focuser, this way avoiding any flexure) and for astrophotography (by connecting SESTO SENSO 2 to the EAGLE or an external Windows computer you can control cameras and accessories for the image capture). By adding the optional coma corrector, inserted in the focuser in front of the camera, you can correct coma (the effect that leads to the stretching of the stars towards the edge of the field) without reducing the telescope focal length. This way you can use the SkyWatcher Newton QUATTRO 254/1000 f3.9 in astrophotography even with cameras equipped with large sensors, up to FullFrame.
