ZWO ASI 120 USB-3 LRGB Manual Filter Wheel Monochrome CMOS Camera Kit

This Super Speed Kit enhances the super speed variation of the ASI120 Monochrome camera from ZWO by adding a 1.25-inch manual filter wheel and a full set of 1.25-inch LRGB filters.

The ASI120MM-S monochrome camera is an ultra fast incarnation of its predecessor, the ZWO ASI120S has the ability to deliver frames at 254 per second with reduced resolution or 60 frames per second at full resolution. This wide range of resolution and capture settings allows you to switch from planetary and lunar imaging to DSO's easily without having to weigh down your set up with an additional camera. The full filter set and included filter wheel further enhances this experience by making it easy to ignore such factors as light pollution, and to use the filters to create beautiful full color images of your night time imaging targets.

Housed in gorgeous metallic red aluminum with both a USB and ST4 autoguider port. 6.5-foot cables for both are included as are a 2-inch M42 x 0.75 threaded interface and standard M42 to 1.25-inch nosepiece. A 1/4-20 thread in the center bottom of the camera makes for easy attachment to a wide variety of camera mounts and tripods. 4 M4 threads offer additional mounting positions, along the outside edge.

A versatile camera has just become faster! Featuring a USB 3.0 connection, image download times are lightning fast. The ZWO ASI120 Super Speed Monochrome camera is a perfect choice for lunar and planetary imaging and features a CMOS sensor sensitive enough to capture bright deep-sky objects. Truly a do it all camera at an incredible price making it the clear choice for the serious beginning or intermediate astrophotographer.

The ASI120MM-S is built on a 1/3-inch CMOS MT9M034 monochrome sensor. Beautiful details are revealed in high resolution black and white. Pair with a filter wheel to capture each color or narrowband and stack images as you choose. The pixel array of 1280 x 960 and a pixel size of 3.75 micron square, this camera is capable of capturing moderately wide fields with the included 150-degree wide angle lens adapter. Peak QE is 75-percent with absolutely no fixed pattern noise. Protecting the sensor is an IR-cut window.

Good. You should improve your stock managing or inventory (because it's not serious the salesman emailed two weeks after the order to say there is no item! it's the second time OPT made this way with me). Second: when the client ask twice or three times about an issue with one order, you normally change the salesman who connect with the client...maybe in some cases it's ok but not in others
