ZWO ASI1600MM Pro USB 3.0 cooled monochrome CMOS camera with mini EFW and LRGB, Ha 31 mm filter set

ZWO has packaged the popular ASI1600MM Pro Astronomy Camera with  Mini Electronic Filter Wheel &  New LRGB Filter Set.

ZWO ASI600MM Pro  Camera

You can get more detail from the link blow:

ZWO EFW mini (5 x 1.25″ or 5 x 31 mm)

The smallest and most lightweight 1.25″ Electronic Filter Wheel in the world!

300g  ONLY ! Small than your hand !

The body is CNC machined from a full block of aircraft grade aluminium.

Very thin design, 20mm ONLY

The step motor is the heart of the EFWmini, which is made by NPM from Japan. You can trust its quality and relability.

Supports both 5*1.25″ filters or 5*31mm filters

The Electronic Filter wheel can be rotated in both counter clockwise or clockwise direction for filter selection.

Only one USB Cable is enough to power up the EFW, the max power consumption is around 120ma@5V, so you can connected it form the USB2.0 hub of our cooled cameras.

The distance between the filter and sensor is aroucnd 10mm when you connect it to ASI1600.

So 1.25″ filters won’t have vignetting up to F5 focal ratio scope and 31mm filter won’t have vigentting up to F2 lens

Our new RGBL filters are recommended to work with ASI1600, it will offer nearly 1:1:1 RGB color balance.

ZWO LRGB 31mm Filters

The ZWO LRGB  31mm filter has better transmission, better coating,  better color separation.

The RGB color combine weights will be approximately 1:1:1.

  • Fine-optically polished to ensure accurate 1/4 wavefront
  • more than 92% transmission at passband
  • Infrared wavelength 700-1100nm cut-off
  • Precision off-band blocking
  • Multi-layers anti-reflection coating
  • Small spectral “gap” to minimize effect of light pollution
  • More parfocal – thickness  2mm

Technical Parameter:

  • Name: ZWO LRGB  31mm filter (4 filters)
  • Size: 31mm
  • Thickness: 2mm

ZWO Ha 7 nm 31mm filter

Narrowband filter do not eliminate the effects of light pollution or increase the object’s brightness. In many cases, they increase the contrast between nebula and night sky, not brightening the nebula.

It can reduce the transmission of certain wavelengths of light, specifically those produced by artificial light including mercury vapor, and both high and low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e. skyglow).

Form 2018, ZWO Made a progress on narrowband filters with new standard, provide better performance.

Technical Parameter:

  • Name: ZWO New narrowband  31mm filter
  • Size: D=31mm
  • Thickness: 2mm

The ZWO  H-Alpha filter  has a bandpass of  7nm and passes light at 656nm  wavelength, light transmission rate comes up to 80%. Best choice of narrowband H-alpha astrophotography filter for high-contrast imaging and revealing rich details of the nebula even in areas with strong light pollution, just prepare to experience the infinite fun with it!

  • Hubble look of images can be made by the combination of H-alpha, OIII-CCD and SII-CCD, such as the famous “Pillars of Creation” (M16 Eagle Nebula)
  • Narrowband imaging with SHO set (H-alpha, OIII-CCD and SII-CCD) can be done with the moon up in heavy light pollution, so your equipment is not sitting dormant for several weeks
  • H-alpha filter is the first narrowband addition to LRGB set for most imagers who blend a black-and-white Ha image into RGB data to enhance structural detail while maintaining natural look
