ZWO ASI174MM Mono USB 3.0 Camera
This NEW camera makes SONY's Pregius Global Shutter CMOS technology available for amateurs without braking the bank. it comes with a large sensor, large pixel size, high frame rate and comparatively high resolution that makes it the best choice for a beginner who want to focus on Lunar and Solar imaging and try his skills in deep sky imaging as well.
(Don't forget that you'll need a proper solar filter in front of your telescope for solar imaging if it's a SCT, Mak or Newtonian and other proper solar technology for refractor telescopes....if you are not sure, ask us for the sake of your safety.)
This camera comes with USB3.0 connection that gives you the opportunity to use it with newer laptops and is backward compatible with USB2.0. There is no USB 2.0 version of this camera as that simply won't be enough to use the camera's possible high framerate. High framerates are not a guarantee for excellent images, but certainly helpful if other circumstances are given.
It comes with an AUTOGUIDER PORT just as many other ZWO cameras do, so you may use it for both imaging or guiding!
This camera will mostly be used for imaging the Sun and the Moon, but it can also be used for deep sky imaging up to a certain level as it supports up to 1000seconds exposure time.
With this monochrome version, if you want colour results, you'll also need a filter wheel and a set of L-RGB filters or H-alpha and OIII filters, and maybe even H-beta and SII filters as well for narrow band astro photography...)
