Kendrick Solar filters use Baader solar film for better performance than glass filters, with no internal reflections to mar contrast and detail. They fasten safely to your telescope dewshield or to the end of the OTA with Nylon screws, and come in many different sizes to fit just about any telescope on the market. 

Simply measure the outer diameter (OD) of your telescope tube or finder scope and order the appropriate filter.

Kendrick Solar Filters can be used for:

  • Camera lenses
  • Telescopes
  • Binoculars
  • Tube OD's from 1.8-16" !

More about Kendrick Solar Filter construction and special technology used:

Kendrick produce full aperture and off-axis filters for all the most commonly used telescopes in amateur astronomy. Kendrick Solar Filter cells are a sturdy powder coated 16 gauge aluminium with 3 nylon thumb screws to facilitate a secure fit on the front of your telescope. Kendrick filters are packaged in a sturdy cardboard or plastic container with inner foam to protect the filter for travel. 

The filter material itself is Baader AstroSolar Film. This film has set a new standard for white light filters and gives a very pleasing and high resolution image. The image colour is a neutral white. Other films and most glass filters produce a blurry bluish or reddish Solar image, thereby cutting out part of the spectrum. Especially with an orange sun, it is very hard to see faculae regions which are visible predominantly in the blue wing of the spectrum. Due to it's neutral colour balance AstroSolar film enables the use of various colour (or interference) filters which allows the observer to use band filters to view different layers within the solar atmosphere. Baader Astro Solar film has consistent Strehl ratios of 94 to 96% on interferometric tests - thus it performs optically like a Fluorite Triplet Lens by Carl Zeiss or Astro Physics and the telescope has the same performance during the day as at night. Baader Safety Film shows notably more sharpness and contrast than any competitive product we know of, including all affordable Mylar or Glass Objective Filters. AstroSolar™ is essentially free from pinholes, since unlike other filters, it is coated on both sides, so the chance of two pinholes overlapping each other is statistically insignificant. Pinholes do appear but to 1 out of 10000 only in an optical density of 2.5. Baader AstroSolar™ safety film has been approved for eye safety by the National Bureau of Standards in Germany the PTB. Unlike any other Solar Filter on the market AstroSolar™ is CE-tested according to EG-Norm 89-686 and EN 169-92 (notified body 0196). Coatings are inspected constantly for consistency to ensure your eye safety.
