EOS Clip-Filters
Hi Guys,
a while ago I purchased an Astronomik CLS EOS Clip-Filter with the objective to get rid of the heavy Melbournian light pollution and allow for longer exposures under sub-urban skies.
I had good visual experience with the 1.25" Astronomik UHC eyepiece filter but wanted something that would be of more general use, not only for nebulae (and of course could be used with the EOS at prime).
Confusion regarding the wavelenghts of the majority of celestial objetcs (apparently they are all a bit different, so there canīt be a one fits all filter) led me to ask in a shop and they advised the CLS filter would be the best solution.
I purchsed and gave it a shot. The outcome wasnīt too great:
all picturs taken through the CLS clip come out blue and stars look out of focus and unnatural. It looks a bit as if the filter does nothing else than making the whitish sky-glow appearing blue (and all objects in the FOV) because the contrast of a galaxy e.g. is not really improved and the surrounding sky looks almost as in daylight.
I am now assuming that the CLS isnīt really a general purpose sky glow filter but a filter for special objects. If that is true:
Can someone please tell me what it is for?
If not:
am I doing something wrong?
And could you please advise what EOS Clip-Filter would be a better solution?
I am looking forward to your advice.
