We were playing with my newly-acquired 6” Dobsonian (gifted to me after the Kejimkujik DSW). Aligned the finder scope with the tube and ‘pushed’ it to the Moon in the E-SE sky. It provided me an upside-down view of the Moon, but lunar features were still easily identified with the mirror-reverse lunar maps.

Refer to Explore the Moon (Telescope) - August 20, 2018 for details.

Also completed this evening was IWLOP #100 - Bullialdus.

Saturn was in the SE sky above our neighbour's back shed. The telescope very clearly provided a view of Saturn and its rings. No ring separation but could see a gap between the planet and its ring structures. This view, however, did vary with the changing atmosphere.

In all 3 eyepieces, Mizar was seen asa double star. As in 2016, there was a third star that formed a triangle with Mizar and Alcor; I later identified it as HD116798.

Below HD 328226 was a line of 4 stars, ranging in magnitude of 11.1 - 13.6 (#1 - #4 in the sketch).

The identified HD238226 and a fainter magnitude 12.9 star to its right as GAIA 1563780481323958784 (#5 in the sketch). Quite the handle!
