Observing Notes

20cm f/6 Newtonian, Cave Astrola @ 76x
Seeing: 6 Transparency: 7 Moon: 0%

Large, a notable nebula encompasing at least four 11-12th magnitude stars, no color noted, no structure noted, the central BD-12 134 is easily visible at magnitude 11.8, about 5' in diameter, low surface brightness makes more magnification unusable, averted vision helps
