Solar Filters  (White Light)
 










OPTICAL FILM SOLAR FILTERS:

R-G SOLAR FILM: Designed with quality and cost in mind, our new R-G Solar Film provides a superior image of the sun at a very economical price. Unlike other brands of thin film solar filters, the R-G Solar Film provides a more pleasing and natural Yellow-Orange image of the sun our customers have come to know and love through our Glass Solar Filter product line. The R-G Film is also available in sheets for mounting in your own cell. Guaranteed 5 years.

BLACK POLYMER: A lower cost alternative where lower magnification is used such as with binoculars, camera filters, finder scopes and small telescopes. Stronger than Mylar with the filtering properties protected within the substrate. Solar image is yellow-orange. Also available in sheets. Guaranteed 5 years.

GLASS SOLAR FILTERS

TYPE 2 + : Made with high quality hand select glass coated with our exclusive Solar II Plus. The most durable glass filter on the market. Guaranteed fifteen years.

FILTER TRANSMISSION: RG, Black Polymer & Glass: 1/1,000th of 1% (Optical Density 5). Great for both visual and photographic use.

FREQUENTLY ASKED QUESTIONS:

WHICH TYPE IS THE BEST OPTICALLY? The RG film offers the highest resolution with high magnification. The glass is a very close second. Under low to moderate magnification, it's difficult see the difference between RG, Glass or Black Polymer.

WHAT SIZE DO I ORDER? The application guide below lists sizes by clear aperture (filter size) and outer cell wall inside diameter (I.D.) The I.D. of the cell slips over and around the O.D. of the telescope tube or lens holder. Please note that the brands and sizes listed are only a guide. Telescope manufacturers sometimes make changes so we strongly recommend the outside diameter of the tube be measured to be sure the correct part number is chosen. Choose the closest outer cell I.D. size larger than the outside diameter measurement of your instrument. Example: part # 4250 (4 1/4") would fit O.D. measurements from 4" to 4 3/16". Do not choose a size the same as your O.D. since it will be too tight and not allow room for a felt lining. Ample felt is included for custom fitting.

ARE THE FILTERS COMPLETELY SAFE? All of our Glass 2+, RG-Solar Film & Black Polymer filters are completely safe for unlimited visual use. If handled with care and common sense, all will last a minimum of 20 years to life.

DO THE ALUMINUM CELLS COME WITH THUMB SCREWS? Thumb screws may seem like a good idea, however, our extensive testing found that in most cases it's actually less secure than a felt lining which covers a lot more surface area for a secure friction fit. If the tolerance is within a few thousands of an inch such as with eyepiece holders, it would be fine, but this is rarely the case. Thumb screws can also dent and scratch the tube and put strain on the filter glass. Thumb screws are simply a "one size fits many" manufacturing shortcut and provide a false security.

CAN THE TELESCOPE OPTICS GET HOT OR DAMAGED? No, all the heat and intense light is blocked before it can enter the telescope. Your telescope may get warm from sunlight shining on it, not from the small amount of visible light transmitted through the filter.

WHAT DETAIL IS VISIBLE? Sunspots and surface granulation are the two main features. The only detail that cannot be seen with a standard filter (commonly called white light filter) are prominence and flares which require our highly specialized H-Alpha filter system.

FULL APERTURE VERSUS OFF-AXIS (REDUCED APERTURE): For telescopes up to 5" aperture, off-axis is not an advantage. Larger apertures suffer more from daytime atmospheric turbulence. This turbulence is magnified by the aperture. Perfect daytime "seeing" only occurs about 1% of the time. Off-axis reduces the aperture and increases the focal ratio thus reducing the turbulent effects. Full aperture can always be stopped down with a simple mask.

WHY ARE THREADED CAMERA FILTERS ONLY AVAILABLE IN BLACK POLYMER? Rg and Glass filters have highly reflective coatings that can cause internal reflections between the filter and camera lens since the filter and lens are in close proximity. This problem is less likely to occur with telescopes, however, mounted telescope filters can be tilted slightly to move any internal reflections off the central axis and out of view.
