Meade DSI III PRO III Monochrome CCD Imager + RGB colour filter

Meade DSI III PRO III Monochrome CCD Imager + RGB colour filter 
The Meade DSI III Monochrome CCD Imager is a continuation of the user-friendly astrophotography revolution. It combines a user-friendly 1.4 megapixel chip, higher resolution, wider field of view and lower thermal noise. Meade engineers have found a remarkable new way to reduce noise without having to use a cooling fan. This means that exposure can last for hours at a time. The thermal monitoring sensors match your dark frames to the ambient temperature so it is almost impossible to take an uncalibrated picture.

Built-in zoom feature
The software has a zoom feature for easier focusing and the square pixels of the new larger chip make production easier. Photos will be better than ever. The Meade DSI III with extremely low noise is the world's best uncooled astro imager.

Difference between DSI III colour and DSI PRO III Monochrome
The difference between the colour version and the DSI III PRO (monochrome) is that the colour version makes, in fact, four pictures on a pixel while the monochrome version only 1 pixel by 1 pixel.

A pixel on a colour camera uses 4 pictures on a pixel because of a (2x2) pattern of colour filters (green, red, blue, green). The computer then combines these data and ensures that a colour photo comes out.

A monochrome CCD camera has 4 times the resolution of a colour CCD camera with the same chip. Then, to convert monochrome images to colours, so-called colour filters are used (or the RGB Colour Filter Set included with this product). This yields red, green and blue monochrome images that you combine into one picture. The resolution is still four times higher than the colour camera, hence the monochrome camera is also known as the PRO version.

Some special features of the Meade DSI III CCD Imager:

• High Sensitivity (1.4MP) CCD Sensor from Sony® The Meade Deep Sky Imager III uses Sony's large 2/3" ExView HAD CCD Image Sensor. This sensor provides dramatically lower noise and a higher dynamic range with a 16-bit A/D converter.
• USB 2.0 High Speed Download pictures with the fast USB connection
• 2x2 Save Mode Use save for fast focusing, centering the image and advanced imaging techniques.
• Multiple Imager Control AutoStar Envisage will support any number of Deep Sky Imager cameras and one LPI, so you can take pictures with one DSI and guide with the other.
• Temperature sensor:The DSI III has a built-in temperature sensor for fast and accurate auto-dark frame subtraction. The temperature sensor matches the current temperature of the CCD chip to each dark frame so it is almost impossible to take an uncalibrated picture.
• Less noise means more data:You get all data from your Deep Sky Imager without compression, which means there's no loss of information in your raw images.
• Drizzle Technology:Drizzle was developed by NASA and produces images from the Hubble Space Telescope. It works with any AutoStar® controlled telescope. Three enhancements were added to Drizzle:
• Enhanced Resolution: Increased resolution without interpolation.
• Extended Observation:a final image that is almost four times longer.
• Field De-Rotation:Eliminate field rotation with a simple two-star selection.
• No batteries needed: Just plug the Deep Sky Imager's USB 2.0 High Speed cable into your laptop or PC and you're ready to take pictures or send them automatically. No other power supply is needed.
• Camera Control & Software:Envisage Software Camera Control and Image Processing Software is included. No need to buy separate, expensive programs.
• Lightweight and portable: Only weighs 311 grams and is very compact, its dimensions are only 10 x 9.5 x 3.17 cm, so adding additional balance weight is not required.
• Versatile: Deep Sky Imager works on any telescope and can also be used as a sensitive and easy to operate Autoguider on AutoStar computerized telescopes.

Colour Filter Set included: to make colour photos with the monochrome CCD imager
The high quality dichotic CCD colour comes with red, green and blue interference filters plus an IR blocking filter. All filters are designed with multiple high transmission coatings and strong 3mm thick glass. The filters are designed especially for the Deep Sky Imager PRO, but they will also work perfectly well with other standard filter wheels from other manufacturers.

Includes filter rings
Meade CCD Colour Filters come with the standard 1.25" diameter with black anodized filter rings. Their par focal design means you never have to re-focus when switching between filters. This unsurpassed interference filters offer the ultimate in specific wavelength transmission. Thus generating true colour images with minimum exposure times.
