"The new DSI-Pro II is nothing short of an absolute joy to image with. The larger chip, greater sensitivity, and major software improvements make this camera a definite contender with “The Big Boys”.

The first, and most obvious improvement in this camera, is the use of the Sony ICX429ALL ExVIEW HAD ½ Inch chip with an imaging area of 752 x 582 pixels. While providing a much larger imaging area then the previous DSI-Pro, this chip also appears to be far more sensitive with a higher signal to noise coefficient. This translates directly into shorter exposures with far greater details evident due to the low noise. I have also found that I am able to capture less images for stacking purposes, again, due to the lower noise output form this camera.

Another improvement in the camera as a direct result of the use of this chip is the actual size of the pixels themselves. On several M31 images I have taken with this camera, the sensitivity of this camera and the smaller pixel size has resulted directly in far greater details in the dust lanes at very short (30 second) exposures then I was ever able to capture in this time period with the DSI-Pro.

Another new improvement that has greatly improved the imaging capabilities of this camera is the ability of the camera to now report the temperature of the chip while imaging. While this is useful information to the photographer, Meade has taken this a step further and utilized this data in the creation of the dark frames that are auto-subtracted from each captured image. Dark frames are now captured and stored according to their exposure length as they previously were but also now include temperature information for each capture. This results in the software always selecting the best dark frame for any given exposure based on the actual temperature of the chip during that exposure. An added bonus is that the photographer is able to utilize this feature to build a permanent library of dark frames based on exposure time and temperature greatly reducing the time required to setup for an imaging session.

Along with improvements in the camera itself, Meade has also made great strides in providing a more robust and full featured software suite with many new options and capabilities. One of my favorite new improvements has been the inclusion of the new “Zoom” feature used by the photographer to help focus the image. By selecting a star and increasing the zoom to 300 – 400 percent, I am able to see very small changes in the focus of not only the selected star but other small surrounding stars that I might not even see under normal resolution. This particular feature has provided an incredible boost to my ability to focus images very precisely without the need for added focus aids such as Hartman Masks.

Overall, Meade has really topped themselves with the introduction of this camera. The DSI-Pro II is far more then simply a follow on to an existing product but instead shows Meade's dedication to providing beginner, intermediate, and even advanced astro-photographers with constantly improving platforms and processes along with a professional level of quality unheard of at this price."
