  • Premium filter set for your monochrome astronomy camera to take beautiful images of planet and deep-sky objects

Product Details

  • The ZWO LRGB2 Filter Set includes four 2” mounted astrophotography filters that pass red, green, and blue bands of light as well the full luminance spectrum across the visible band. By taking individual images with each of these filters and a monochrome astronomy camera and combining the separate images with standard processing techniques, you can create beautiful correct-color images of planets and deep-sky objects.

    This premium filter set is designed to approximately equalize the sensor response of the ASI1600 monochrome camera, and the RGB color combination is weighted to approximately 1:1:1 for accurate color rendering. These filters also work well with other monochrome astronomy cameras. 

    All filters have a mechanical thickness of 5mm, with another 2.5mm added for the thread. Each filter is more parfocal with a thickness of 1.9+/-0.03mm. The filters are mounted in cells with standard M48x0.75 threads for use in most filter wheels that accommodate 2” filters.

    The precision passbands of the LRGB filters include a gap between red and green to improve color balance and partially block the sodium line at 589nm to suppress light pollution from low and high pressure sodium lamps. The blue and green filter passbands overlap slightly to include emission from OIII to help achieve a more natural color when imaging nebulae. The ZWO LRGB filters also block infrared wavelengths from 700nm to 1100nm which means a separate IR-cut filter is not required. Each filter has a transmittance of at least 92% in band, and each is optically polished to ¼ wave to help you get superior images. All surfaces have multi-layer antireflection coatings for increased transmittance and elimination of ghost reflections.

    This set is not suitable for imaging with DSLRs or one-shot color astronomy cameras because they include a Bayer array to achieve color images intrinsically.

CMOS finally comparable/better than CCD technology for Astronomy

A game changer, both in price and performance. It has proven that CMOS technology can surpass CCD technology. My first use of CMOS for Science and not disappointed. Does require deeper study so one can most effectively understand proper setup of Offset and Gain depending on your target. More documentation on setup of Offset and Gain would be good for new owners, however. Imagine an image with the field of view of a 16803 (CCD chip) camera, at less than half the price; as well as quieter signal! I’ve now used both for Science! Ron Diiulio, Director (ret.)

My First Dedicated Astrophotography Camera, What a Delight!

I started astrophotography as a hobby in January 2021 with a DSLR. I had no background in photography and didn't even own a telescope until this winter. I planned to start with just a DSLR that I bought in January, but I quickly got addicted. I received my ZWO ASI6200MM and kit with the 7 position filter wheel and ZWO LRGB and Ha, SII, OIII filters a couple weeks ago. I had never used a dedicated astrophotography camera prior, let alone a monochrome camera with a filter wheel. When I received the camera, filter wheel, and filters I loaded the filters into the wheel and sorted through the spacers that came with the camera and wheel. I was able to get the backfocus I needed using the pieces that came with the EFW and camera. I had to do some cable management, and I did need to buy a large losmandy style dovetail (thanks OPT!) to get it balanced. I already had the ASCOM platform and drivers for ZWO cameras for my guide camera, so everything was essentially plug and play right out of the box and connected with no additional software to my current capture software. This camera is amazing. I live 5 feet above sea level, have poor transparency, high winds, high humidity, and Bortle 6 skies with Bortle 7 light domes a couple miles almost all around me. My scope is f/4.7 with its reducer, but it is only 382mm. I never would have thought I would be able to get images like I am now on smaller targets especially from my backyard, but the sensor in this camera picks up amazing details even in poor conditions and the resolution is huge. I would also like to thank OPT and Ron specifically for working with me to split out the camera, EFW, and filter wheel from the kit so that I could begin using the camera. I had asked about splitting the order on the online chat and closed my browser right away without waiting for a response. The next day I had an email stating the order would be split, and a few days later I had everything on my scope. The Hubble shot of the Pillars of Creation is one of the first images of space I remember ever seeing and is to this day one of if not my favorite image. Four months into the hobby, only 2.9 hours of integration (6x300s Ha, 17x600s OIII, and 12x300s SII) with poor seeing, and I was able to take my own picture of M16 and the Pillars of Creation. I still have plenty of learning on how to process images, but it's a journey I am excited to take. Space is amazing.

Heavy and bulky

Make sure your telescope is long and heavy enough to balance this filter wheel.

An absolutely awesome camera

The quality of this camea is very good. Like other ZWO products, its solidly built and has a huge sensor with 62 Mega Pixels. I tried it out on a couple of scopes and the camea performed fine, with 2" adapters, you get the full frame view. This is one of the top-of-the-line cameras from ZWO, and is sure to provide excellent performance, ideal for use in astrophotography or astronomical research.

The ASI6200mm is a joy to use. Setting it up was easy using published documentation for the camera and the filter wheel that I purchased at the same time. I used only a OSC SLR before so I had to learn new post techniques.

Flexible and easy to install

Pretty easy to install. I used it with a filter drawer on a harmonica drive mount. It reduced the guiding error down to 1/3 of a guidescope. With it I was able to guide consistently under 1" error using a RST-135, and achieve round stars for 5 min exposure. Recommended for harmonica drive mounts.
