The Advanced Solar Observer (ASO) and Research Grade filters are high quality, narrow and ultranarrow bandpass filters for observing the solar chromosphere. The ASO is for the advanced amateur or college level observer. The Research Grade is for when the highest uniformity and ultra narrow filter are required. The filters are based on 38mm optics and have a 32 clear aperture (C.A.). The filters are mounted in aprecision Thermoelectric controlled oven (TEC). The advantage of the TEC oven is that it has the ability to regulate the temperature, or wavelength, of the filter by either heating or cooling as needed. Telescopes with 60mm or larger apertures have to contend with the extra energy that the sun is adding to the filter. With a standard oven, the controller only operates to the heating set point. Above the set point the controller is simply off. The extra energy from the sun will drive the band pass into the red wing and off of the H-alpha absorption line. The temperature controller will accept a wide range of input voltages: 85 265 volts A.C. This will allow it to be used almost anywhere in the world. Advanced Solar Observer (ASO) and Research
Grade filters are designed for use with telescopes with f25 or longer that are equipped with an energy reduction filter (ERF). These
ultra-narrow filters will work poorly with Barlow lens systems. They are more suited to off-axis telescopes with the right wedge plate, or
Telecentric systems. Research grad Filters are available in 46 mm clear aperture on special demand. ASO filters are grouped into four bandwidths, all of which are capable of observing broad band features like prominences and flares, but are narrow enough to observe the solar chromosphere.
Deciding which bandpass to choose depends on what your primary interests are. The broader filter (0.8) is a good choice for general viewing; with this filter you have the capability of seeing the active areas and filaments on the solar disk. The midrange filter (6.5) will give you more contrast on the disk, but still allows superior views of prominences. The narrower filter (0.5) will give you even higher contrast on the solar disk features while allowing the fine structure in the prominences to be observed. The ultra-narrow filters (0.3) and under will give views of the sun which were previously only available to the professional observer. At bandwidths under 0.3, the prominences will become three-dimensional and features that were barely visible at 0.5 ang. will show large amount of detail. Research Grade filters with their ultra-narrow bandwidths and high uniformity will meet the requirements of the serious researcher.
