Is UHC-S filter worth to buy?

[Guest]

Hi, I was wondering if Baader's UHC-S filter is worth to buy. I would like to know if it is good for imaging with my 80/400 achromatic refractor, not modded Canon EOS 600D on EQ2 (I'll get EQ3-2 soon) mount with single axis motor drive. Thanks in advance!

It is a good filter to use with a DSLR, especially if you get a full spectrum mod.

It improves contrast whilst preserving emission nebulosity.

It,would not be suitable for imaging galaxies or reflection nebulae from a dark location though as it will dim these significantly.

 

I have two of them, both sat on my binoculars at the moment

Ok, thanks! Unfortunately, my DSLR don't have any mod :/
