Model: Baader_lrgb_125Part Number: 2458472Brand: Baader
Baader's NEW line of premium quality Baader LRGBC filters are designed to compliment their narrowband emission line filters (H-beta/OIII/H-alpha/SII).
L UV/IR Cut
Note: The LRGB filters include IR-block coatings so the clear filter is necessary if you wish to image the full spectrum, including IR, otherwise you need only order the LRGB filters. All the filters, including the clear filter, are very nearly parfocal so there is little or no need to refocus between filter changes.

I contemplated whether to buy Astrodon RGB filters or the Baader RGB filter for a while but am glad I settle on the Baader filters. My first image taken with the filters came out really well, despite the less than optimal weather conditions severely limiting the amount of exposures. The previous reviewer said they used a light pollution filter in front of these. However, initial image results show little or no sign of light pollution effecting the images, which I am very pleased with since light pollution is quite bad where I live. Couldn't be more pleased with these filters, great value for money and excellent filters.
I bought the LRGB 2" set and they are absolutely excellent - everything you expect from high-quality LRGB filters for imaging with monochrome CCD cameras. I use a Hutech IDAS LPS 2" filter in front of these to suppress light pollution and they work perfectly as well. No internal reflections are produced by the LRGB filters themselves and the colour produced is remarkable and very well channel-balanced (though there is always a green colour cast to combined RGB images but this is easily removed in post-processing). The focal point is the same for all LRGB filters so you focus one, lock the focus and the rest are focused in the same level as well. As a note, I image unbinned (1x1) in L and 2x2 binned in RGB, all on the ATIK 383L+ CCD camera.
