the UCF 2 is not just a nebular filter, it is much more versatile. It is an excellent all-purpose filter - suitable both for beginners and advanced observers. It can be used on all telescope sizes and types

Some Examples of Use
>> Jupiter & Saturn ... strong gain in contrast on reddish details, like the Great Red Spot on Jupiter, or any other red details on a planet. Compared with a normal colour filter the image will not be tainted as much, resulting in a more “natural“ image.
>> Mars ... Mars is notoriously a planet with weak contrasts. The contrast is boosted with the TS UCF filter, working out previously invisible detail, in particular on the polar caps.
>> Moon ... The filter reduces glare and improves contrast, in particular on details that do not lie near the terminator.
>> Twilight Observing ... contrast is improved, the blue glare on the sky is reduced for a darker background.
>> Daytime Observing ... another application in which contrast is boosted without causing an unnatural coloration of the object.
>> Gas Nebulae ... similar in function to a classical nebular filter the UCF 1 boosts contrast, in particular in the red H-Alpha emission line. The background is reduced in brightness, working out details also in other wavelengths. The UCF 1 filter is less extreme than more narrow-band filters - highly recommended for small telescopes where conventional filters swallow too much light. (up to approximately 114mm aperture, but the filter of course works also with bigger telescopes)
