Baader LRGB Filter Set - 1.25" Round Mounted
Baader LRGB Filter Set
What good is a filter if it's not built to last? And that's why Baader Planetarium has such a good reputation. Each individually crafted filter has its edges sealed and the ultra-hard ionbeam deposition ensures the coatings will never degrade from normal use or cleaning. Anti-reflection coatings are applied evenly to both sides of the filter, ensuring no surface stress and no warping of the substrates. All of this adds up to a filter that will last a lifetime.
Now Baader Planetarium introduces their new LRGB Filter Sets. Through an exclusive partnership with the world's leading thin film coating company, they've now produced filters which can produce almost perfect photographic results. With unbelievably high cut-offs and transmission rates (>95%), this RGB filter set is able to achieve what no other can - the separation of the H-Beta and O-III lines.
The blue filter passes all the H-Beta and O-III lines and the green picks up the spectrum of the O-III line without blending into H-Beta with no light lost between the two. Thanks to this combination, O-III and H-Beta colors can now be captured as it was meant to seen. What's more, the red and green passbands kick the light pollution line out at 580nm, and the high transmission rates mean the shortest exposure times possible.
In addition, the Green and Red filter passbands nearly touch, leaving only a sharp notch to block out the primary Mercury/Sodium light pollution line at 580nm. The high transmission everywhere else delivers the shortest combined exposures possible. With their special coating stacks, the Baader Planetarium LRGB filters effectively toast reflections, too. As you can see in the above image taken by Mr. Johannes Schedler, Sirius looks very different when imaged using an L and C Filters from Baader Planetarium!
Get it all! Why - for heavens sake - would you want to throw away precious light from Deep Sky Objects? It has always been amazing to the folks at Baader Planetarium that every serious Astro imager is looking for the ultra sensitive, back- illuminated Wonder CCD Camera - and then the precious energy of O III and other desirable emission gets cut off by at improper filter design. Don't waste your light any more..

Questions & AnswersAsk a Question
I see these filters described as being good for DSO, but would they be equally as good for planetary imaging with a mono cam like the ASI 174MM?
Yes, these filters will work well for planetary imaging as well, although you might have to tweak the color balance slightly to deal with atmospheric refraction and extinction depending on how high in the sky your target is when shooting the planets.
