DSI II and DSI Pro II. Giving high cost imagers a run for their money.
“The larger chip, greater sensitivity, and lower noise make the DSI Pro II
a definite contender with “The Big Boys. — Steve Hamilton

DSI II
The user-friendly astrophotography revolution continues with the larger, more sensitive, higher resolution
DSI II and DSI Pro II. A number of astrophotographers have written to tell us that the DSI II (or DSI Pro II)
has turned their expensive cooled camera into a primary auto-guider. Mark Sibole of Fife Lake, MI, says, “I
owned a more expensive cooled imager in the past and didn’t get images like I get with the DSI II. I’ve since
sold that expensive camera because I wasn’t using it any more.”
The DSI II (color) and DSI Pro II (monochrome/color filter) cameras combine ease-of-use with a larger
chip, greater sensitivity, higher resolution and dramatically lower thermal noise. Meade engineers invented a
remarkable new way to reduce noise without a cooler. This means you can take exposures for hours at a time.
And new thermal monitoring sensors match dark frames to ambient temperatures so it’s nearly impossible to
take an uncalibrated picture.
The camera has a new zoom feature for easier focusing and the squared pixels of the new larger chip make
processing simpler and images more beautiful than ever. The DSI II is the world’s first un-cooled camera with
low thermal noise. And that’s as cool as it gets.
Compared with the standard DSI, the DSI II gives you:
+ Dramatically lower noise.
+ Larger 8mm diagonal (type ½) chip.
+ 74% higher resolution.
+ Greater sensitivity.
+ Temperature sensor.
DSI II user Chuck Reese says, “I did not have to take dark frames because the software can match the operating
temperature of the chip to the perfect dark frames taken from previous sessions. My hat is off to Meade. I
was expecting an incremental step forward but the DSI II is more like a quantum leap!” Steve Hamilton
agrees, “The DSI-Pro II shows Meade’s dedication to providing beginner, intermediate, and even advanced
astrophotographers with constantly improving platforms and processes—along with a professional level of
quality unheard of at this price.”
The pictures and testimonials speak for themselves. If you want to own the absolute best of the user-friendly
Meade imager family, get a DSI II or DSI Pro II.
