During the night between 23rd and 24th of August 2014 I had an opportunity to do some observing with the large telescopes of Tähtikallio Observatory, Finland. This time I was observing with the 16” Meade of Tähtikallio observatory. The targets that I observed were comet Jaqcues and planetary nebula NGC 6905.

Comet Jaqcues was visible as a round and fuzzy object. In the middle of the coma, there was a rather starlike central brightening. The brightness of the coma decreased gradually outwards. The visual diameter of the coma was about 5′. No tail was visible visually.

NGC 6905 is a planetary nebula in constellation of Delphinus, the Dolphin. The nebula is know as the Blue Flash -Nebula. I made following notes of my observation:

@101x: small, round fuzzy spot, no details. @270x: oval-shaped nebula, long axis SW-NE -oriented. Central star visible with averted vision. Visual size roughly 1,6’x1,3′. The eastern part of the nebula seems to be brighter than other parts of the nebula.

Weather during the night wasn’t optimal, there was some haze in the sky, and the sky wasn’t completely dark yet. Besides this, there were some occasional clouds moving across the sky. Eventually these clouds forced me to stop observing after I had barely finished observing NGC 6905.
