Nearer Jupiter opposition.The planet began to appear in the sky earlier, but the conditions for its observation still remain unfavorable because of the small altitude.On this night, due to atmospheric turbulence, it was not possible to capture small details.Soon the haze came and the atmosphere deteriorated sharply, we had to stop shooting.However, at least something.
I am owner of the filterSvbony CLS, that reducing well in strong light pollution, but it’s difficult to get the correct white balance.For shooting in the suburbs, I needed a weak light pollution filter, which carefully cut off the light of sodium and mercury lamps.
Modern technologies make it possible to manufacture filters with a very interesting bandwidth.One of these filters designed for astrophotography is Optolong L-Pro.It selectively attenuates the light of sodium (589 nm) and mercury (578 and 435 nm) lamps, which are sources of urban illumination, and transmits a useful signal from stars and nebulae.
Of course, the light pollution filters are not a panacea – they allow at least something to be photographed under flare conditions, or to significantly reduce the effect of light pollution. The price for this is to increase the shutter speed or sensitivity for confident work on the object in the picture. Unlike the UHC \ CLS \ LPR filters, considered in the Optolong L-Pro review, it can also be used for objects of stellar nature (galaxies, nebulae, clusters). Due to the wide bandwidth, it is much easier to get an correct white balance with the L-Pro filter, since with the CLS \ UHC filter the green channel is almost the same as the blue one. Читать далее…
