Resolution Comparison
Capturing astronomical images during moments of good seeing is tough. This comparison shows two images shot on the same night with the same equipment just minutes apart. The image on the left measures 1.61 arcseconds per pixel FWHM. The image on the right measures 2.45 arc seconds per pixel FWHM. Visual comparison shows tighter stellar images and fainter stars in the image on the left which was captured during a moment of exceptional seeing.
The images are each single 3 minute exposures of Messier 2. They have been dark and flat corrected. No other processing was performed.
