I am considering replacing my present 6 nm Astronomik Max FR filters on my Epsilon 130D (f3.3) with the much narrower "Chroma OIII (3nm) Imaging Filter Optimized for f/2.8-f/3.6" (link is to the O3 but they have the others as well).  Should have higher contrast (and price ) for my lightly light polluted home site.

Anyone using these with a fast system and an IMX 455 or IMX 571 camera and have there been any issues?

Thanks!

The high f ratio optimized filters do not carry a higher price, they are just a custom order at the time they are placed. We’ve sold a number of sets of these to customers and have not heard of any negative experiences. All of our experiences were on Delta Rho systems deployed remotely.

Or you could keep the Astronomik filters, take the Chroma money, sell the E130 and buy an E160….
