Description: Bode's Nebula. Pretty low surface brightness but despite of that I was able to detach two faint spiral arms. The eastern one is brighter and sharper than western. The core is pretty bright and small, it's surrounded by an oval halo. Several stars involved.

Description: M82: Ytimen itä-puolella pieni lovi, joka ei kuitenkaan halkaise koko galaksia. M81: Kirkkaan ytimen ympärillä vaalea ''huntu'' vailla yksityiskohtia. Etualalla kolme Linnunradan tähteä. NGC 3077: Ydin aavistuksen kirkkaampi kuin galaksin ulko-osat.
