The ZWO ASI294MM Pro Imaging Kits include the following items:
The ZWO ASI 294MM PRO is a highly versatile monochrome cooled camera with a 4/3" sensor. 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 ASI533 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.
ZWO LRGB & 7nm SHO filters are designed to have a balanced spectral response with modern CMOS monochrome cameras. Each filter is optically polished and multi-coated.
Optolong LRGB & 7nm SHO filters provide excellent transmission over 80% and off-band blocking, making them a great choice for an affordable price.
Antlia LRGB & 3nm SHO filters give professional, high contrast results even under very light-polluted skies. The maximum transmission is between 88-90% with transmission off-band only 0.1%.
