ZWO ASI1600MM PRO with EFWMini, 31mm RGBL Filter Set & 31mm H-alpha 7nm Filter BUNDLE
ZWO ASI1600MM PRO COOLED Deep Sky Imaging Camera with EFWMini, 31mm RGBL Filter Set & 31mm H-alpha 7nm Filter BUNDLE
ABOUT THIS BUNDLE:
ZWO has packaged their upgraded ASI1600MM-COOL, the new ASI1600MM-PRO Astronomy Camera with their NEW 1.25″ Electronic Filter Wheel, their NEW 31mm RGBL Filter Set and their latest development, the 31mm 7nm narroband H-alpha filter. These LRGB and narrowband filters have been designed specifically for this camera to maximise the output of the camera. A perfect set up for deep sky imaging!
WHAT'S IN THE BOX:
- ZWO ASI1600MM-COOLED camera
- ZWO EFWMini NEW 5-position 1.25″ (31mm compatible) Electronic Filter Wheel
- ZWO NEW 31mm RGBL Filter Set designed for ASI1600 series
- ZWO NEW 31mm H-alpha 7nm narrowband deepsky filter
WHAT'S NEW: DDR Memory Buffer
The 256MB DDR memory buffer is the main difference between the previous ASI1600 “Cool” and the latest “Pro” cameras.
Whilst the original ASI1600MM-COOL is a perfectly capable USB3.0 camera, those who wish to use it via a USB2.0 port, can now do it with better success as the addition of the 256MB DDR3 memory buffer means more stable data transfer even at the lower speed of the USB2.0 port, plus reduced amp-glow for the same reason.
WHAT'S NEW: Further Improved Mechanical Structure
The ASI1600-PRO uses 4 screws to seal the chamber. This structure has been fully tested and is very stable and reliable.
Even under high humidity eviroment, ASI1600-PRO still works fine and won’t have dew problems.
WHO IS IT FOR?
The ZWO ASI1600MM-PRO COOLED camera is an excellent choice for imaging deep sky objects, however it can do much more than that. With a max framerate of 23 FPS this camera can also be used as an extremely high resolution planetary imager. If you cannot decide if your thing is deep sky or planetary imaging, go for this camera. It is also a much more affordable alternative to converting a dSLR.
The ASI1600 features a built-in 12bit ADC, but can also provide 12.5 stops dynamic range which is even better than the competing KAF8300 sensor dew to its super low read noise, so it could be a good alternative to much more expensive professional CCD cameras.
This version also comes with built-in active cooling that helps to reduce electronic noise to the minimum.
There are four versions with the same large 4/3" sensor (21.9mm diagonal):
Colour or monochrome and cooled or uncooled.
Now you will have to decide whether you want a simple solution and go for a one shot COLOUR CAMERA or would like to get more data out your camera and go for the MONOCHROME version. If you would mainly use it as a deep sky imager camera, we'd also recommend to go for the COOLED version, but if you cannot afford or you'd be mainly using it as a very high resolution planetary imager, then go for the UNCOOLED version.
This product listing is for the COOLED MONOCHROME version of the ASI1600.
Here are links to all available versions:
ASI1600MC: UNCOOLED COLOUR VERSION (the deep sky imaging astronomer's quick tool)
ASI1600MC-PRO: COOLED COLOUR VERSION (the deep sky imaging astronomer's quick ultimate tool)
ASI1600MM: UNCOOLED MONOCHROME VERSION (the deep sky imaging astronomer's ultimate tool if you have a bit more spare time)
ASI1600MM-PRO: COOLED MONOCHROME VERSION (the deep sky imaging astronomer's ultimate tool for very best images if you have a bit more spare time)
Why not to try L-RGB or narrow band photography with the monochrome version of this camera, the ZWO ASI1600MM or ZWO ASI1600MM-PRO.
If you are not in rush, but you'd like to get out the best result from your camera, this monochrome version is the right choce for you, although if you are on a tight budget, you could also consider the UNCOOOLED version instead.
Consider that with this monochrome version you'll also need a filter wheel and a set of L-RGB filters or H-alpha and OIII filters, and maybe even H-beta and SII filters as well for narrow band photography...
To choose the right bundle with the right sized filters and filter wheel, please read the following section...
LIMITING FOCAL RATIO
Please note that the sensor diagonal size is very close to the internal clear aperture of a 1.25" filter, therefore with very fast telescopes or if you will use the camera with a fast photographic lens, telephoto lens etc. there might be vignetting. (lens with small f-ratio: photographers call it a fast lens because it takes less time to achieve the same brightness of the image)
The limiting focal ratio with the ZWO manual filter wheel depends on the thickness of the filter glass and its clear aperture. The latter is usually 24 or 26mm for 1.25" filters. The cheaper ZWO LRGB filters that were developed for planetary imaging have 24mm clear aperture, but fortunately, the new LRGB filter that were developed for the ASI1600MM and ASI1600MM-PRO COOLED cameras have 26mm clear aperture...
Earlier calculations were approximate figures as those were based on assumptions rather that precise measurements as at that time we did not yet have the new filters and electronic filter wheels in stock.
We have now took some measurements and recalculated the limiting f-ratio and to our surprise the results are much better, there will be much less vignetting...
limiting focal ratio= (filter to sensor distance + thickness of filter) / (filter clear aperture - sensor diagonal size)
Calculation for a 1.25" filter with 2mm glass (EFWMini or EFW 8*1.25"/31mm)
(8.4mm + 6.5mm + 2mm + maybe 2mm more due to the cell) / (26mm - 21.9mm) = f/4.6
(f/4.85 with 3mm glass and f/5.1 with 4mm glass)
good for a fast newtonian at f/5 or SCT at f/6.3
Calculation for a 31mm filter with 2mm glass (EFWMini or EFW 8*1.25"/31mm):
(8.4mm + 6.5mm + 2mm) / (28mm - 21.9mm) = f/2.8
(f/2.94 with 3mm glass and f/3.1 with 4mm glass)
this would be good for a fast Newtonian or APO at f/4 or even faster...or to be used with a telephoto lens at f/2.8 or slower
Calculation for a 36mm filter with 2mm glass (EFW 7*36mm):
(8.5mm + 6.5mm +2mm) / (35mm - 21.9mm) = f/1.3
(f/1.38 with 3mm glass and f/1.45 with 4mm filter glass)
so this would be good for imaging with a really fast dSLR camera lens at f/1.4 (or slower) or maybe even with a really large SCT with a Hyperstar at f/2 (wouldn't make sense for a 8", 9.25" or maybe not even for 11" SCT to use a filter wheel in front position with a Hyperstar, but I could imagine a 14" SCT with a Hyperstar in that sort of configuration...although for any Hyperstar we would usually recommend Starizona's own filter drawer instead of a filter wheel...

due to the large sensor size, the usual 150 degree wide lens IS NOT included as it is not compatible, but there might be some other compatible lenses that would work with this camera. If you know about such lens, please let us know, so that we can share it with other users as well.
