Comparing to the astrophotographic application the visual use of the EdgeHD OTA´s is very tolerant. You won´t notice any negative effect or at least
it is minimal and therefore acceptable.

Of course, our narrowband filters can also be used with a color camera, but there are some trade-offs.

You will definitely sacrifice some resolution for the flexibility of an One shot color camera (which is ideal for EAA and planetary imaging - DSO, not so much). For narrowband, the sensitivity reduction of an OSC camera compared to a monochrome is a direct result of the Bayer matrix. Bayer matrices are usually RGGB, so only 1/4 of the sensor picks up Ha radiation through the red filter. With OIII, you're a little better off - it will be about 1/2 as sensitive as a monochrome camera with the same sensor. The real problem comes with SII. It's in the far red, and the red filter in a Bayer matrix will attenuate some of that radiation. Also, SII is generally quite weak in DSO targets to begin with. So using an OSC camera with an SII filter can require some pretty massive integration times to get enough SNR to make a nice image.

So it's not that you can't do it - you can. But you're essentially giving up a lot of imaging time by choosing an OSC over a monochrome camera for DSO narrowband imaging. If this is going to be an occasional pursuit and you don't have heavy light pollution, then the OSC makes sense. If you're in heavy light poulltion and you're going to be doing mostly narrowband imaging, then it makes a lot more sense to get a mono camera.

Unfortunately, we cannot answer this question without knowing what telescope you are using.

For example, with a 2032mm C8, 2x Barlow and our Hyperion at 8mm magnification, you can see great structures on Saturn and Jupiter.

The following page is a great starting point to determine the actual magnification and approximate image from your combination of telescope, Barlow lens and eyepiece: http://astronomy.tools/calculators/field_of_view/

If you have the filter wheel in the QHY CFW3-S Standard version, you can screw either our 1.25" mounted filters and the 31mm version into the filter wheel. The threads are standardized and fit into all filter wheels from QHY or other manufacturers.

If you have the QHY filter wheel in the QHY CFW3-S Ultrashort version, our 1.25" filter mounts with a height of 6 mm are unfortunately too thick. Due to the short mechanical length, it can only accommodate 5 mm thick filters. The unmounted 31 mm are not affected by this filter wheel version.

You need a T-2 prism diagonal (## 2456095 or # 2456005), a T-2 nose piece (1.25" # 2458105 or 2" # 2408150) and a glasspath corrector.
For the Schmidt-Cassegrain, we'd recommend the 1,25x GPC (you can reach focus without it, but it improves image quality and illumination); for the refractor, it depends on the available back focus. The T-2 prism diagonal is recommended as it makes the shortest adaptation possible - in theory, any other star diagonal can work, but it may be too long so that you probably will not reach focus or need a stronger glasspath corrector.

We have a description of the different adaptations and how to measure the back focus in the manual at https://www.baader-planetarium.com/en/downloads/dl/file/id/1614/product/4317/manual_baader_maxbrightr_ii_binoviewer.pdf
