There are two spots there, SOHO says so. I didn’t expect to see anything without binoculars but was out in the sun so looked anyway

This was Marcos’ first session with his Galileoscope so it was mostly helping him to get accustomed to how it works.

We looked at

  • Moon and saw mare Crisium, Proclus and earthshine
  • M42 and noted nebulosity
  • Venus which was just a dot of light but definitely planetary

Naked eye we observed two ISS passes, an Iridium flare, Pherkad and Mizar.

We moved down to TPO for the second ISS pass and from there observed Saturn which appeared to have a thin line bisecting the planet – the rings – and M45 which overflowed the eyepiece.
