I shot “luminance” with an H-alpha filter on an Esprit 150 at f/4.6 and “color” with an L-eNhance filter of an Esprit 100 at f/5.5. With the 1600 mono and 294 color cameras that works out to a color pixel scale about twice the size of the mono, so it’s like taking binned 2x2 color data but at the same time. Really needs more exposure time but it was a good first test of my dual scope setup.
