. 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!! .

Galaxies are diffuse objects which are imaged against a background of finite brightness and noise. Galaxies which have the maximum contrast with respect to this background are the ones that are first discovered. ... These galaxies have been missed to date but active surveys for them are underway. ... In this page we present several examples of these newly discovered Low Surface Brightness galaxies as well as examples of high surface brightness galaxies. ...
