The ZWO ASI294MM Pro Kit 2 includes the following items:

 

The ZWO ASI 294MM PRO is a highly versatile monochrome cooled camera with a large sensor which is ideal for wide field astrophotography. This new mono version of the ASI294 features the Sony IMX492 back-illuminated sensor which is natively binned 2x2 to give 4.63 µm pixels, ideal for long focal length telescopes, but can be unbinned to give small 2.3 µm pixels for wide focal length scopes such as refractors.

The ASI294MM Pro has an outstanding QE value with a peak of 90%, ultra-low read noise of 1.2e- and full well capacity of 66,387e-. The camera has a 14-bit ADC with a high dynamic range of 13 stops, higher than the popular ASI1600MM Pro.

 

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 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. This close distance prevents any vignetting with 1.25″ filters for telescopes up to f/5. For f/2 lenses/telescopes it is necessary to use 31mm 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.
