Hi Arief,
Is there any reason why that is so? I have no doubts that aperture make a difference, but just curious that as to why that is so. Interesting thing is that I've got a 3" and an 8" ... so is that an excuse to buy both??!! Hee hee

Regards,
Jeremy

The UHC is too aggressive for smaller scopes, the image will be too dim.

Hi,

A good UHC filter will not reduce much light, but the contrast increase will be a lots more than the light reduce.

But I think the O3 and H-Beta filter will not be that suitable for small scope.

Have a nice day.
