Sun in April, 2020

It has been a while since I looked at the Sun through a telescope.  This mildly-warm Spring day with few clouds seemed like the perfect opportunity to see what the fireball in the sky was up to.

This was a somewhat rush job, as technically I needed to get back to my job.  But all in all in turned out ok, I think.  I could see two extremely small sunspots together in the upper quadrant.  If you look at the full-sized image, you may be able to find them as a small black smudge.

Equipment Used:

  • 254mm Mak-Cass telescope
  • 23mm eyepiece
  • Orange eyepiece filter
  • Solar filter for telescope lens

  • Nightcap app on iPhone with settings:
    • f/1.8
    • 1/300 s exposure
    • ISO 24
    • 4 mm focal length

  1. Hey Paul… Those black smudges are likely dust spots or perhaps jpg artifacts. There is one tiny sunspot on the Sun but it is in the upper left quadrant. The “smudge” is not in the same location as your smudge. Check out for a current image of the Sun and the sunspot.

    Nice capture!

    • Thanks. I definitely saw, at the telescope eyepiece, two very small, basically tiny, spots on the sun right next to each other, which correspond to the smudge on the image. Looking at’s image of the sunspots, that is exactly what I saw, though yes what I saw was more centered. I am assuming some sort of rotation difference, either us, the Sun, or both.
