Baader Photo AstroSolar Film ND3.8 (imaging only), telescope quality for digital solar imaging at high magnifications with short exposure times. Not suitable for visual Solar Observation! ND3.8 film is 20 x 29cm (7.9″ x 11.4″)
The Baader U (Venus) Filter enables amateurs to successfully image in the deep UV from 300nm to 400nm. The filter has a peak transmission of 80% and completely blocks the rest of the spectrum from 200nm to 1500nm.
Used to record cloud structures on Venus, the Solar Calcium K-Line is also within the passband of this filter.
Visual & Photographic AstroSolar ND5 Safety Film, high density coatings on both sides of a specially manufactured foil reduce the intensity of sunlight by up to 99.999%. The sun’s image is extremely contrasty and white,
DSLR Astro Conversion Filter for Canon EOS 5 D Mk II & 6D
Baader have made an IR cut filter that replaces the standard internal Canon filter. This filter has high transmission of the H-Alpha line and eliminates the cameras’ major disadvantage for astro-imaging.
The Baader Complete Filter Set – 36mm, contains an LRGBC filter set as well as the three Hubble palette emission line filters, Ha 7nm + OIII 8.5nm + SII 8nm.
Consists of 8 Filters (2459546) glass thickness is 2mm.
These 3.5 nm H-alpha Enforced-Narrowband Filters open up the extremely narrow 3.5nm H-alpha world.
This enforced contrast results in even fainter stars, providing more signal of faintest nebulae detail. Manufacturing such ultra-narrow filter does require extreme coating homogeneity and very high CWL precision, which these filters are designed for (CWL= Center-wavelength).
