The acclaimed Deep Sky Imager (DSI) camera series is BACK, and it’s more advanced than ever.  Equipped with a 16MP Panasonic CMOS image sensor, regulated two-stage thermo-electric cooler, and 3.8µm pixels, the new DSI-IV is the ideal camera for all of your astrophotography pursuits.  The low-noise, high-resolution and fast USB 3.0 readout make this camera suitable for both deep-sky and planetary imaging, making it one of the most versatile astronomy cameras available. 

The DSI-IV offers immense value beyond the camera itself.  It not only comes with its own high-quality, weather-resistant hard carrying case and AC power adapter, but we’ve included a new version of SkyCapture camera control software. With complete camera control, SkyCapture can run automatic image capture sequences without the need to purchase additional software. Capture high-quality images and video of galaxies, nebulae, and other beautiful objects of the night sky with Meade's DSI-IV.
