Visibility III / V
Sunspot group 2842 in three ways: hydrogen alpha double filter, hydrogen alpha single, white light.
The first is the Lunt 80 DS, the second the Lunt 80 SS and the third the Celestron C8 white light
The camera is all the same, black and white ASI 174. I have subsequently colored the images so that the color matches as closely as possible what I see from the eyepiece.
All have 2.5 x Powermate. Image scale With Celestron, of course, a different, effective focal length at 2.5 x 2032 = 5000 mm. The Celestron white filter is really yellow (Celestron Eclipsmart).
For each I have taken a series of 1000 pictures, of which Autostakkert stacked about 20%. After finishing: sharpening IMPPG, coloring Gimp and finishing Lightroom.
