ZWO ASI1600MM Pro USB 3.0 cooled monochrome CMOS camera for deepsky imaging. Features: sensor 4/3″ CMOS, resolution 16 Mpx 4656x3520, pixel size 3.8µm, exposure range 32µs-2000s, delta T 40-45, interface USB3.0/USB2.0, bit rate 12bit output (12bit ADC). Includes mini EFW and the following 31 mm filters: LRGB, Ha.
ZWO has packaged the popular ASI1600MM Pro Astronomy Camera with Mini Electronic Filter Wheel & New LRGB Filter Set.
You can get more detail from the link blow:
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.
1.25″ holder(with cover and 2 screws)
A bag of Spacers
USB2.0 2m cable
A bag of M2 screws
The ZWO LRGB 31mm filter has better transmission, better coating, better color separation.
The RGB color combine weights will be approximately 1:1:1.
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.
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!
