The QHY268M Kit 5 includes the following items:
- QHY268M cooled monochrome CMOS camera
- QHYCFW3-M 7 x 36mm Ultra Slim motorized filter wheel
- Chroma 36mm LRGB filters
- Chroma 36mm 3nm SHO filters
This camera has a two-stage TEC cooling system that brings the temperature of the sensor 35/40C° below ambient for low noise imaging, even in warm climates. The QHY 268M has zero amplifier glow no matter how long the exposure is.
The QHY 268M employs a full anti-dew technology for both CCD sensor cover glass and the sensor chamber optical window. In order to avoid halos around bright stars, the QHY268M has an AR coated optical window on both sides rather than the common IR/UV cut window.
The motor is enclosed to prevent dust from entering, thus improving reliability and the durability of the motor. The QHYCFW3 main body is CNC machined from a single piece of aluminium, sandblasted and anodized for a high quality finish.
Chroma Technology manufactures the highest quality filters on the market today with durable, sputtered hard coatings using single substrates of the best glass, eliminating the need for laminations. All primary filter coatings are applied on the front surface and anti-reflection coatings on the rear surface to prevent ghosting and to maximize transmission.
Highly precise and accurate, the passbands of these filters remain spectrally stable and do not drift in response to extreme temperature fluctuations or changes in humidity. All filters may be used with apertures of f/4 or smaller.
