ZWO ASI533MM PRO IMAGING KIT

The ZWO ASI533MM Pro Imaging Kits include the following items:

• ZWO ASI533MM Pro cooled monochrome CMOS camera
• EFW Mini 5 x 1.25"  or EFW 8 x 1.25" motorized filter wheel
• Your choice of ZWO 1.25" LRGB filters, Optolong 1.25" LRGB + 7nm SHO filters, Baader 1.25" LRGB & 6.5nm SHO or 3.5/4nm SHO filters, Antlia 1.25" LRGB & 3nm SHO filters, or Chroma 1.25" LRGB and 3nm SHO filters.

The ZWO ASI 533MM PRO is the long-awaited monochrome version of the incredibly popular ASI533MC Pro cooled camera and features a 9Mp back-illuminated CMOS sensor with 91% quantum efficiency at 460nm.

The ZWO Mini Electronic Filter Wheel weighs only 300 grams, it is CNC machined and the optical thickness is only 20mm. This model can take 5 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 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.

Baader CMOS-optimized LRGB & SHO 6.5nm and 3.5 / 4nm filters are precision-grade filters with high transmission at their respective emission lines. They are designed to work very well with modern highly-sensitive astronomy cameras and telescopes with focal ratios between f/15 to f/3.4.

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%.

Chroma Technology manufactures the highest quality astronomy filters on the market with durable, sputtered hard coatings using single substrates of the best glass, eliminating the need for laminations. All primary filter coatings are applied on the front surface and anti-reflection coatings on the rear surface to prevent ghosting and to maximize transmission.

Highly precise and accurate, the passbands of these filters remain spectrally stable and do not drift in response to extreme temperature fluctuations or changes in humidity.
