In the course of my mono transformation, I decided on the LRGB filters from Baader Planetarium. I had already outlined the criteria and reasons for this decision in the main article on the mono transformation.
To summarize briefly: I am starting my journey into the mono world with a set of LRGB filters, but I know that in a few months, I will expand my filter collection to include narrowband filters.
The reputation and experience of the manufacturer were important factors for me. Additionally, the availability of very narrowband filters and an outstanding price-performance ratio played a role. From Baader Planetarium’s wide range of filter sizes, I chose the 50.4mm filters.

The transmission lines often provided by many retailers, as shown in the diagram, indicate—at least in my interpretation—very steep rising and falling cutoffs for the respective Baader filters, which also remain consistently at a high level.
First practical experience with Baader’s CMOS-optimized LRGB filters
I can almost always think of something to write. In this case, it’s a bit like a good IT department: you don’t even notice it! And that’s in the best possible way—I have absolutely nothing to complain about.
In my previous mono imaging sessions, I’ve had to deal with all sorts of challenges. Most of them are covered in my recent articles, but the Baader filters have been rock solid when it came to troubleshooting and error correction. I simply didn’t have to worry about them.
All my images have shown only sharp and high-contrast data.
From my perspective, Baader Planetarium’s meticulous quality control truly pays off, and I’m already looking forward to expanding my setup with Baader’s narrowband filters.
A closer look at the details of the Messier and ARP objects highlights the capabilities of the mono system. The key optical components include the Baader Apo 95 CaF2 Travel Companion, the IMX455 mono sensor of the SkyEye62AM, and the Baader filters mentioned here.
I’m very excited to capture more images with my mono setup—also with my Vixen VC200L!
