Baader C2 Swan Band 15nm Filter£68.00 - £137.00
The Baader C2 SWAN-Band-Filter with ≤ 15 nm Half-Band-Width isolates the two C2 lines at 511 and 514nm – leading to a contrast gain for comet hunters!
Baader Solar Continuum Filters£73.00 - £160.00
This Baader Planetarium Solar Continuum Filter comes in a fully-threaded 1.25" & 2" round cell.
Works in conjunction with a primary white light solar filter (or Herschel Wedge Prism) to show more granulation and sunspot detail!
Baader 7.5nm Solar Continuum Filters (540nm)£101.00 - £170.00
The Solar Continuum Filter is practically a narrow band photosphere filter for solar observation in white light. It provides the highest contrast in the photosphere of the sun.
Astronomik OWB CCD Type 3 EOS Clip Filter£116.00
The OWB filter would usually not be designated as an "astronomical" filter. The intention is to enable converted DSLR cameras (without inbuilt IR-filter) in order to be used for 'terrestrial' photography.
Optolong L-eXtreme Dual Band Narrowband Filter£163.00 - £209.00
L-eXtreme is a two 7nm bandpass filter which can be used with one-shot color cameras like DSLR's (digital SLR), and
monochrome CCD cameras, it is also more suited for fast systems.
