Hi gang,
Filter technology has changed and improved greatly over just the last few years. As such, my 30-year-old set of 1.25" LRGB filters is well past its 'sell by' date, and I would like to update it. I use them with a QSI CCD camera on an 11" EdgeHD scope under ~Bortle 4 skies. 

I certainly would appreciate hearing from many of you on the brands you use, your likes and dislikes, and preferences. Again, these will be used with a CCD camera, which I understand differs from those used with CMOS sensors.

Many thanks for all your thinks. The imagery here on AB is astounding, and I assume that your expertise and newer filter technology are the culprits!smile

All the best,
Steve

Hi Steve,

I am using Antlia LRGB-V Pro 1.25" Filters. I have absolutely no issues with them, and the images look great (although I'm still learning in processing :wink-1smile.
They are paired with my RC8 or 80mm Refractor, and work perfectly with both, at f5.3 and f8. Camera is Asi533MM Pro.
Images are sharp, uniform and without halos, although I feel like my B filter is not perfectly sharp, but I have never used anything else so I don't know if it looks normal or not.

Overall I can recommend them from my limited experiences.

I'm also using a C11EdgeHD and a QSI CCD camera under Bortle 4 skies, though it is my 2nd favorite rig behind my refractor setup due to problems with dew/frost in my area.  For the C11EdgeHD / QSI 660ws combo, I made out great with 1.25" Astrodon filters for years, but they were old Astrodon filters from the years before the company changed hands.  I recently added a 3 nm Chroma Oiii filter to the filter wheel in my QSI 660ws, and it has produced halo-free images of several planetary nebulae. 

If I had to buy a new filter set right now, I'd go for all Chroma filters (regardless of price) and not look back.  For narrowband, if you want them, I'd go with 5 nm bandpass rather than 3 nm.  The signal from the 3 nm Oiii is a little too weak for my tastes, and many stars essentially disappear in my C11 EdgeHD images, making registration and stacking more difficult. 

Keep in mind that the Chroma filters are 3 mm thick, Astronomik filters are 1 mm thick, and many others are 2 mm thick.  Try not to mix and match thicknesses if you want filters to be parfocal.

my 5C

Chromas beat Antlias, but by a very slim margin.
These brands, both, beat the ZWO filters by quite a big one.

IMHO that applies to NB also
