The QHY268M Kit 6 includes the following items:
- QHY268M cooled monochrome CMOS camera
- QHYCFW3-M 7 x 36mm Ultra Slim motorized filter wheel
- Optolong 36mm LRGB filters
- Optolong 36mm 3nm SHO filters
The QHY 268M Monochrome contains the Sony IMX571, a high performance back illuminated cooled monochrome sensor with true 16-bit A/D. This translates to a dynamic range of 14 stops for vibrant and natural colours, even in faint or dark nebulae. The pixels have a size of 3.8 µm which is an excellent value for telescopes with different focal lengths.
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 QHY CFW3 Medium is a motorized filter wheel designed for 7 unmounted filters with a diameter of 36mm. It uses a high quality ultra-thin hybrid stepper motor that compared to standard electrical motors, is more precise as it has a smaller stepper angle.
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.
The NEW Optolong 3nm H-Alpha, Oxygen-III and Sulphur-II narrow-band filters boost the contrast of emission nebulae and supernova remnants for professional results, even under a bright sky affected by light pollution. This filter is used in combination with the OIII and SII filter to compose a narrowband colour image.
The Optolong LRGB 36mm unmounted filters are specially designed for deep space photography with monochrome cameras. The strict manufacturing process and the quality control guarantees a tight tolerance of the filter thickness (± 0.05mm) which makes these filters parfocal. This allows the filter change without the need to refocus.
Each filter is fully multi-coated to minimise internal reflections, halos around stars and to assure a high transmission which is above 95%.
Each filter cuts off the ultraviolet and infrared light so there is no need to use the L filter in combination with the colour filters.
