Meade Deep Sky Imager (DSI) IV


Suitable for both deep-sky and planetary imaging.

The DSI-IV is expected in the United Kingdom in April 2019.


The acclaimed Deep Sky Imager (DSI) camera series is back, and it’s more advanced than ever.

Dual Purpose Camera

Equipped with a 16MP Panasonic CMOS image sensor, regulated two-stage thermoelectric 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.


Product Features

With complete camera control for all major operating systems including Windows, Mac OS X and Linux, SkyCapture can run automatic image capture sequences without the need to purchase additional software.
