After buying and trying a number of filters recently I've ended up with two of these so I'm putting this one up for sale. It's in good condition and comes in original plastic case.
Although called 'UHC' this is really a broadband filter. Visually it helps with reflection nebulae (e.g. parts of M20) that are suppressed by narrowband filters. I don't image but as a broadband filter this would be useful for imaging.
