. NEVER look directly at the sun without a proper solar filter! . We have lots of different equipment available for use. Here you see our 6" solar filters. Our club always recommends that you use a FULL APERTURE solar filter. In the picture you will notice a TYPE 2 filter for VISUAL use and a TYPE 3 filter for PHOTOGRAPHIC use. Here is an easy way to remember which type solar filter you need for VISUAL OBSERVING: You have 2 EYES so you need a TYPE 2 filter!! .

... The RCB carbon abundance remains an enigma ([ Asplund et al. ... The strength of a stellar absorption line represents the ratio of line opacity to continuous opacity in the atmosphere; both are related to the number density of the absorbing atoms and so provide the number ratio of line absorbers to continuum absorbers. ... Since the predominant continuum absorber in RCB atmospheres is neutral carbon, it has not yet proved possible to measure the carbon abundance from carbon absorption lines. ...
