Sun spotter solar filter for telrad professional#
My sun photos are now, to my eye, of a professional standard and could only be improved with a hydrogen alpha scope. The packaging claims the optical quality to be equivalent to glass solar filters and I without doing a comparison myself, I do not doubt for a second that this could be the case. This solar film is, if you pardon the pun, night and day compared to earlier filter types I've used, such as mylar film.

Especially with an orange sun, it is very hard to see faculae regions which are visible predominantly in the blue wing of the spectrum.ĭue 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 for investigations of different layers within the solar 'atmosphere'.ĪstroSolar™ is essentially free from pinholes, since - other than with even the most expensive glass filters - it is coated on both sides, so that the chance of two pinholes overlapping each other is extremely faint. Other films and most glass filters produce a blurry bluish or reddish Solar image, thereby cutting part of the spectrum.
With AstroSolar™ the Sun appears in its real colour - neutral white. Roll: 100 x 50 cm Baader AstroSolar™ film This foil is CE-tested and reduces the intensity of sunlight by 99.999%.
