The QHY600L Kit 1 includes the following items:
The QHY 600L - Light version is a full frame CMOS cooled astronomy camera containing the monochrome version of the Sony IMX455, a revolutionary full-frame back illuminated sensor which has a QE above 87% and true 16-bit A/D. This translates to a dynamic range of 14 stops for vibrant and natural colours, even for faint or dark nebulae. The pixels have a size of 3.76 µm which is an excellent value for telescopes with different focal lengths.
The large sensor has a resolution of more than 61 Megapixels allowing to crop, scale and print the frames in large formats.
The camera has a two-stage TEC cooling system with full anti-dew technology that brings the temperature of the sensor 35C° below ambient for low noise imaging, even in warm climates. The QHY 600L has zero amplifier glow no matter how long the exposure is. The QHY CFW3 Large is a motorized filter wheel designed for 7 filters with a size of 2" and 7 unmounted filters with a diameter of 50mm.
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.
All the QHY filter wheels have a female dovetail ring for the QHY cameras. Under this removable ring the CFW3 Large filter wheel has a standard M54 x 0.75 female connection.
The Optolong LRGB 2" 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.
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.
The design of these filters is optimised to cut out the typical yellow emission of the sodium and mercury lamps around 589nm. The Optolong 7nm H-Alpha, 6.5nm SII & 6.5nm OIII narrow-band filters boost the contrast of emission nebulae and supernova remnants for professional results, even under a bright sky affected by light pollution.
The maximum transmission of each filter is above 80% and the transmission off band is only 0.1%. This is a value often undisclosed by other filter producers and it is critical to darken the sky background and minimise the halos around the stars.
