Since its introduction in May of 2008, the Orion StarShoot Pro has sent shockwaves through the astro-imaging community, setting a new standard for price and performance. Now weâ?TMve outdone ourselves again by improving the StarShoot Pro with refined features and functionality to provide the very best in affordable imaging technology. Our enhanced StarShoot Pro V2.0 brings cooled, multi-megapixel color imaging into the realm of never-before-seen affordability. Its Sony 6.1-megapixel color CCD chip boasts a 3032 x 2016 pixel array in a 23.4mm x 15.6mm format. That gives the Pro 6.5 times the image area and over four times the pixels as similarly priced astro CCD cameras. In fact, it uses the same chip found in cameras costing thousands more! The Pro's square 7.8 micron pixel size provides an excellent balance between high resolution and sensitivity. With some cameras in cooler weather conditions, condensation can form on the surface of the optical window, due to the temperature of the optical window being affected by the cooled CCD. Our enhanced design prevents this by virtue of increased distance between the CCD chip and the optical window. You get detail-rich shots with enough resolution to make large format color prints! For the intermediate or advanced astro-imager, or for beginners seeking a camera they won't soon outgrow, the enhanced Orion StarShoot Pro V2.0 delivers award-winning high-resolution performance for an unprecedented low price. Get yours today!

• Astronomy camera attaches to a telescope to take stunning astrophotographs you'll want to hang on your wall and share with friends or fellow astronomy club members
• The on-board 6.1-megapixel Sony CCD sensor measures 25.10mm x 17.64mm and features a 3032 x 2016 pixel array for sharp astrophotograph resolution
• Thermoelectric cooling (TEC) and an adjustable on-board cooling fan minimizes background noise for clear and sharply detailed astrophotographs
• Compatible with Windows XP, Vista, and 7 Operating Systems (32 bit and 64 bit). ASCOM drivers are available for use with a number of popular image processing programs, such as Nebulosity, ImagesPlus, and more
