ZWO ASI174MM USB 3.0 Monochrome Astronomy Camera Kit with 5-Position Manual Filter Wheel & 1.25″ LRGB Filter Set (Older Version) – ASI174MM-KIT ZWO

ZWO ASI174 Monochrome Astronomy Camera

ZWO’s ASI174MM Monochrome is a CMOS Imaging Camera that surpasses even their ASI120MM-S when it comes to cutting-edge functionality like a high-speed USB 3.0 port, an ST4 guide port, a standard 2” interface with M42x0.75 internal threads, a 1/4” tripod thread mount on the back, and an AR window. However, the ZWO ASI174 camera has one important difference, and that is the inclusion of a Sony IMX174 monochrome CMOS sensor. This image sensor has a lot going for it when it comes to high quality solar, lunar, planetary, and deep sky imaging.

Sony IMX174 CMOS Sensor Features

• 1/1.2” CMOS: The Sony IMX174 is a 13.4mm (Type 1/1.2) CMOS image sensor with 2.35 MP effective pixels in a 1936 x 1216 array. Pixel size is 5.86 µm square.
• Pregius Global Shutter: The development of a new pixel with analog memory allows for all pixels to be scanned at once. This global shutter function on the Sony IMX174 sensor means images taken of moving objects will not suffer from focal plane distortion, resulting in high picture quality. This is a really nice feature, especially when you are doing lunar or solar imaging. Bad seeing, wind, or movement can distort the image if the readout speed is not fast enough (<30fps).
• Exmor High-Performance: Exmor is a Sony trademark, and that label means the CMOS image sensor is considered a high-performance model, with high-speed processing, low noise, and low power dissipation by using column-parallel A/D conversion.
• High QE, Low Noise: As a general rule, we should be aiming for high QE and low noise. The peak quantum efficiency (QE) for the ZWO AI174 camera is 78%. The QE curve is slightly higher in B & G than the ASI120, and slightly lower is R and IR. Oh, the read noise? It measures out at only 6e-!
• High Frame Rate: At full resolution, the Sony IMX174 sensor operates at 128.2 frames per second at 12-bit ADC and 164.5 frames per second at 10-bit ADC.
• ROI Mode: Achieve an even higher frame rate with ROI (Region of Interest) mode. This mode allows you to set a maximum of 16 areas for capture inside the effective pixels area.
• Everything you will need to control your ZWO camera is available and easily downloadable in one centralized location on the ZWO website. Click here for ZWO Software Downloads.

Please Note: This camera works with Windows 8.1 as long as you have the recommended driver installed (available on the ZWO website at zwoptical).

ZWO 5-Position Manual Filter Wheel

• The ZWO 1.25″ Manual Filter Wheel is a great addition to any ZWO Monochrome Astronomy Camera!
• This 5-position filter wheel lets you easily organize the filters you plan on using for the nights imaging session.
• Handles up to five 1.25″ filters.
• To select a filter all you have to do is turn the numbered dial and choose a filter. Each position securely clicks into place for use.

ZWO 1.25″ LRGB Filter Set

• The ZWO LRGB Filter Set includes four filters: 1.25″ IR-CUT, 1.25″ Red, 1.25″ Blue, and 1.25″ Green.
• Each filter in the ZWO LRGB filter set delivers over 90% light transmission.
• All filters are housed in a sturdy filter cell and have anti-reflective coatings.
