Notes: W winds and Atlantic air is back, bringing much better conditions than on Sept 9. The view is better without the deep sky filter, a sign of good air. NGC 7805 is noticeably brighter than 7806, round with a non-stellar core. NGC 7806 is oval 3:2 with the major axis pointing to 7805. I see a hint of spiral structure maybe? The companion MCG+5-1-26 (mag 16.5) was not seen although the two faint stars on either side of it were seen E of the main galaxies. |
