Astronomik UV-IR Blocking Luminance Filters




The Luminance channel is perhaps the most critical aspect of creating a superb final image. In order to achieve the greatest signal quantity, the filter being used should have the highest possible transmission with a wide spectral bandpass. These two elements allow for the highest sensitivity and give you maximum photon counts on your pixels. Even though the high level of transmission is an excellent characteristic of these new Luminance filters, perfect color correction is not universal on all optical instruments, or additional optical elements such as correctors, reducers, and flatteners. Thus, problems may arise due to the Luminance filter's spectral bandpass width. Stars may appear soft or bloated due to the transmission of incompletely focused light (chromatic aberration) if the band pass is too wide. When this happens, image processing can be difficult. However, this damaging result can be reduced or completely nullified by having a spectral window that is slightly narrower in your Luminance filter.



Astronomik has recently expanded their Luminance filter line to provide you with all the tools needed to gather the best possible data. Now you can select the Luminance filter best equipped for your specific telescope system to get the highest signal with the most clear image for Luminance channel.



Your telescope's color correction will determine whether you should use a filter with a wider spectral window for the Luminance channel. The L1 features the widest spectral window, while the L3 has the narrowest. The L2 is roughly the same as the current Astronomik L-Filter.



If your optical system is completely chromatic aberration free, you should get an L1 filter for your setup. For general use with most optical systems employing a corrector, flattener or reducer in the optical train, the L2 is optimal. The L3 filter is made for users with refractors that have less than ideal color correction. Plus, when used in conjunction with Astronomik's new Deep-Sky RGB filters, the L3 filter will reduce that annoying bluish halo around stars.



The transmission curve characteristics and coatings on the new Luminance filters have been designed and engineered in such a way that no halos or reflections will be visible. Even with bright stars in the field of view you will be able to reveal the faintest structures in galaxies or nebulae.



Like all Astronomik Filters, the new Luminance filters are made using an extremely durable and scratch resistant coating, deposited on the finest polished optical substrate, which is free of any striae or internal strains. All substrates are made to exactly the same thickness, so all Astronomik filters are parfocal.



Astronomik UV-IR Blocking Luminance Filter Highlights




  • Parfocal with any filter made by Astronomik
  • Fully resistant to scratching as well as the effects of aging and high humidity
  • Diffraction limited, this filter maintains the current optical performance level of your telescope
  • Astronomik filters arrive with a long-lasting plastic storage container of superior quality




Astronomik Clip-Filter System




This Clip-Filter system, exclusive to Astronomik, is constructed from black anodized aluminum and laser-cut on ultra modern machines. It can be inserted directly into the Canon EOS DSLR camera body within seconds. Modifications are not necessary and all lens functions such as focus, screen, and image stabilization, continue to operate as before! All Canon system lenses, besides the EF-S series, as well as all M42 and T2 lens adapters, are suitable for use with the Astronomik Clip-Filter system. Plus, during long exposures, this system serves to protect your sensor from accumulating dust.
