The Meade Instruments 16MP Monochrome Deep Sky Imager IV is a high-resolution digital imaging system that allows you to capture monochrome images by itself, or attach single or stacked astronomical filters for custom-colored images through a 2" focuser, visual back, or other accessories like Barlows or diagonals. M42x0.75 threads allow it to be mounted on a variety of imaging accessories. Images are captured using a 4/3" 16MP imaging sensor and sent directly to your Windows or Mac computer running the included SkyCapture imaging software via the fast USB 3.0 connection. It is also backward compatible with USB 2.0, but download speeds will be slower. The fast download speed of USB 3.0 allows you to gather more images in less time, which is critical if the weather and atmospheric conditions are fluctuating and you have limited time for imaging. Whether you're looking at the Moon, Mars, or the rings of Saturn, the monochrome DSI-IV takes your view of the sky and makes it available for everyone to see.
