. 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!! .

This module supports ISAPI Extensions within Apache for Windows. ... This module implements the Internet Server extension API. It allows Internet Server extensions ( e.g. ISAPI .dll modules) to be served by Apache for Windows, subject to the noted restrictions.
