Details:
Today, I was doing an experiment with ultraviolet and infrared light's affect on solar imaging. I chose to use the wavelength of 393.4nm, which represents singly ionized calcium ions in the solar chromosphere. ----As you can see the affect of minimal optical density blocking; versus optical densities 3 and 5. The image quality difference is quite dramatic. ---
----- This is a home made calcium K-line filter, and the processing software was registax5.1; Each image consists of 900 frames stacked and equally sharpened to reveal the details. Uncontrolled Infrared light and Ultraviolet light, will ruin imaging data.----80mm x 1200mm telescope--- basler 1300-30gm monochrome ccd
