ZWO ASI183MM PRO KIT

The ZWO ASI183MM Pro Kit includes the following items:

• ZWO ASI183MM Pro cooled monochrome CMOS camera
• EFW 8 x 1.25" motorized filter wheel
• Optolong 1.25" LRGB filters
• Optolong 1.25" Ha, SII and OIII filters

The ZWO ASI183MM PRO is a cooled camera with small 2.4 micron pixels, making it ideal for objects with short focal length telescopes. It features a 20Mp back-illuminated CMOS sensor with 84% quantum efficiency.

The ZWO Electronic Filter Wheel weighs only 400 grams, it is CNC machined and the optical thickness is only 20mm. This model can take 8 x 1.25″ mounted or 31mm unmounted filters.

The Optolong LRGB 1.25" 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%.

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.
