Visual Filters

Astronomik visual filters  are a valuable accessory for use with your telescope and are correctly optimized for naked eye visual observation, allowing each object to be viewed with maximum contrast through your eyepiece. 

The difference between Visual and Photographic CCD Series Filters:
The human eye is not sensitive in the infrared range like CCD imagers and photographic film. For this reason, Astronomik Visual Filters do not have integrated IR Blocking. 
 

Quality Characteristics of Astronomik filters:

  • Astronomic visual filtersSuperior Substrate: Astronomik filters consist of a precision polished substrate on which the actual filter, in the form of very thin (dichroic) interference layers, is applied. Because of these high quality measures Astronomik filters will in no way reduce the performance of your optical system. And contrary to common experience with other manufacturers´ filters, with Astronomik filters stars remain fine needle points of light!
     
  • Coating: Astronomik filters consist of up to 130 layers deposited on top of the completely transparent carrier glass. These layers work as the actual filter and as an antireflective coating.
     
  • Durability: Astronomik filters are completely scratch resistant, and not sensitive to moisture, dew, or high humidity. With others’ filters, after a few years, you start to notice their filter is no longer up to its full capability. Not so with Astronomik filters which maintain their ‘brand new’ transmission specifications year after year.
     

Astronomik filters are high quality accessories for visual observing which will significantly expand your observing opportunities. After many years of use your Astronomik filters will be an accessory which will be ready to give you the same joy you experienced many years earlier when they were new.
