Newtonians have always been the best-selling reflecting telescopes since they offer large diameter at a really low price. This Newton QUATTRO 200/800 f4 by SkyWatcher is perfect for long exposure astrophotography of deep-sky objects thanks to the ESATTO 2" robotic microfocuser that allows the use, without flexures of slippages, even of heavy cameras and accessories. Thanks to the fast f/4 focal ratio and the compatibility with the very good f/4 optional coma corrector, you will be able to record great pictures of galaxies, nebulas or star clusters. This telescope comes with ESATTO 2" robotic microfocuser, 8x50 optical finder, support rings and Vixen type dovatail bar. 3 years of warranty on the optical tube!
SkyWatcher Newton QUATTRO 200/800 f4 telescope has a Crayford focuser that doesn't offer a high load capacity so it is not recommended for long exposure astrophotography with heavy cameras or accessories. This special version of the SkyWatcher Newton QUATTRO 200/800 f4 adds ESATTO 2", 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 M56x1 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)! In order to connect different cameras and reach focus, you have to add one of the many optional adapters with T2, M48, M54, etc threads. And you can also expand ESATTO features by adding the ARCO robotic camera rotator!
SkyWatcher Newton QUATTRO 200/800 f4 with ESATTO 2" and the following optional accessories: 235mm PLUS support rings, Vixen style 240mm PLUS dovetail bar (below the tube), EAGLE with guide scope in parallel (above the telescope) and ECCO environmental module.
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 200/800 f4 in astrophotography even with cameras equipped with large sensors, up to FullFrame. By adding EAGLE to the SkyWatcher Newton QUATTRO 200/800 f4 telescope you can remotely control and power any camera, mount and accessory for astrophotography, using any of the most advanced astronomical software for Windows (you can install in the EAGLE the software you prefer) and converting your SkyWatcher Newton QUATTRO 200/800 f4 into the most advanced robotic telescope.
