H alpha spectroheliograms comparison

Post by fulvio.mete »

Halpha spectroheliogram of today, h 7.35 a.m UT.The first image is the image extracted from the pixel on the very center of the line, of 0.02 Å bandpass; the second is the average of 30 frames centered on the line (one for each pixel) of the video of the scan, with about 0.6 Å of bandpass.
The difference in the visibility of the details, however small,is perceptible.
