Up until now, SHO narrowband imaging typically required three separate filters, a pricey monochrome camera, and at least three sets of data acquisition. With this Askar Color Magic Ultra E Filter Package, however, SHO narrowband imaging is easier and more affordable than ever before! With just two filters and your color camera, you can collect all three wavelengths—Hydrogen-Alpha (Ha), Sulfur-II (SII), and Oxygen-III (OIII)—with just two data sets, helping you save both time and money.
