Last Saturday (21 May 2016 @~18:48 (UT+3)) I made a picture of the Sun using Canon EOS 600D camera with common ES-S 55-250mm f/4-5.6 IS II lens (BAADER Astrosolar film was used as a sunfilter).
A rather big sunspot is visible in a disk of the Sun. To emphasize a size of the spot I put my old image of Jupiter (taken with small 65mm Newtonian + Canon IXUS 132 compact camera) near the spot with the same scale (linear sizes of the planet and the Sun were taken from Wikipedia).
To the left of Jupiter is an image of Earth (from Google Earth, also in the same scale -- it could be simple blue ball because almost no details are visible at such scaling)
The picture is a result of an averaging of 10 individual frames processed with PIPP, AS2, Registax6.
Initial frames were captured at the following conditions:
ISO=100
F=1/11
Exp=1/4000s
