The ZWO ASI6200MM Pro Kit 4 includes the following items:


The ZWO ASI6200MM PRO is a high resolution camera with a full-frame back-illuminated 16-bit Sony IMX455 sensor featuring a QE up to 80%.

 Sony’s back-illuminated CMOS technology improves sensitivity, minimizes noise, reduces power consumption and increases data download speed.

The ASI6200MM Pro features a 16bit ADC that can achieve a dynamic range output of 14 stops. This improves the image contrast significantly and the brightness shades are smoother and more natural.


The ZWO 7 x 2" Electronic Filter Wheel is CNC machined and has an optical thickness of only 20mm. This model can also take 7 x 50mm round unmounted filters.

The power absorption of the EFW is only 120mAh @ 5V so any USB cable can power it up. The distance between the filter and sensor of the ASI 6200 is only 18mm. Unmounted filters with a diameter of 50.4mm ± 0.5mm can be used in the 2" filter wheels. 


The Antlia LRGB series 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.

The NEW Antlia 3nm Pro ultra 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 3nm band pass is only 1% of the entire visible spectrum increasing the signal to noise ratio delivering high contrast images and extremely dark backgrounds. To even further enhance the contrast, and suppress the stray light and internal reflections, Antlia applies edge-blackening coating on each filter.

The maximum transmission is 88% - 90% and the transmission off band is only 0.1%. This is a value often undisclosed by other filter producers although it is critical to darken the sky background and minimise the halos around the stars.
