About this product

Astro Essentials SeeStar S50 Baader Film Solar Filter with Case

Improved sharpness and contrast vs the included solar filter

Designed specifically for the ZWO SeeStar S50. 

It is manufactured using Baader AstroSolar™ Material, which provides higher sharpness, contrast, and detail than the standard solar filter included with the SeeStar S50.

3D printed in tough, black filament. 

This product is 3D printed, so it has the usual minor imperfections, like layer lines, associated with 3D printing.

Baader AstroSolar™ film

With AstroSolar™, the Sun appears in its real colour - neutral white. Other films and most glass filters produce a cool/blue or warm/orange colour Solar image, thereby cutting 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 its neutral colour balance, AstroSolar enables the use of various colour (or interference) filters, which allows the observer to concentrate on certain spectral passbands to investigate different layers within the solar 'atmosphere'.

Eye safety

AstroSolar™ is essentially free from pinholes. Since it is coated on both sides, the chance of two pinholes overlapping each other is extremely faint. Pinholes do appear, but to 1 out of 10000 only in optical density 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). All processes connected to this product have been thoroughly tested. Coatings are inspected constantly for consistency to ensure your eye safety! 

NOTE: This solar filter is designed only for use with the ZWO SeeStar S50. Do not use it with any other telescope. 

IMPORTANT: Never view the Sun without a suitable Solar Filter! Before every use, check that the solar filter fits securely and covers the full telescope aperture. Solar observing is dangerous and can be hazardous to eyesight. Safety is everyone’s responsibility - please read the safety notes supplied with the product carefully.
