The ZWO ASI2600MM Pro Kit 2 includes the following items:
- ZWO ASI2600MM Pro cooled monochrome CMOS camera
- EFW 7 x 36mm motorized filter wheel
- Antlia 36mm LRGB filters
- Antlia 36mm Ha, SII and OIII filters
The ZWO ASI2600MM PRO uses the back-illuminated Sony ExMor IMX571 APS-C sensor. It features a QE up to 80%, a native bit rate of 16 bits, an ultra-high 14 stops dynamic range and ultra-low 1.0e readout noise.
Like the colour version, this camera weighs only 700 grams! The APS-C sensor has the size of 23.5mm x 15.7mm for a diagonal of 28.3mm. Sony’s back-illuminated CMOS technology improves sensitivity, minimizes noise, reduces power consumption and increases data download speed.
The ASI2600MM Pro features a 16bit ADC that can achieve a dynamic range output of 14 stops. This improves the image sharpness and contrast significantly and the colour shades are smoother and more natural.
The ZWO Electronic Filter Wheel weighs only 400 grams, it is CNC machined and the optical thickness is only 20mm. This model can take 7 x 36mm 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 Pro cameras like the ASI1600 is circa 10mm.
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.
