76mm f/6 APO, TeleVue-76 @ 14x
Small, bright enough to be quite obvious, a halo easily visible around the core, NGC5195 visible on the northern margin, easily found by sweeping south from Alcor, viewed without and then with supplemental oxygen, no major difference seen in the galaxies despite the altitude of 13,600ft

46cm f/4.5 Newtonian, Deep Violet @ 175x
Stunning! Big, bright, a wonderful spiral surrounding a bright core, two spiral arms wrap around the core, a bridge of material reaches to the companion NGC5195, a 14th magnitude star overlies the spiral in the southwest quadrant, always a showpiece object with a large 'scope and a dark sky!
6 Apr 2007 Hale Pohaku, HI (map)
15cm f/5 Newtonian, Primero @ 97x
Bright, large, beautiful halo around a bright core, spiral arms clearly visible with averted vision, about 10' across, NGC5195 visible at northern margin and connected by a bright bridge of material, a sublime sight even in a modest telescope given nearly perfect conditions at a true dark sky site

20cm f/10 SCT
Both galaxies clearly visible, some structure barely visible, large, bright, obvious cores

Very faint nebula, without stars, near the eye of the Northern Greyhound, below the star Eta of 2nd magnitude of the tail of Ursa Major: M. Messier discovered this nebula on October 13, 1773, while he was watching the comet visible at that time. One cannot see this nebula without difficulties with an ordinary telescope of 3.5 foot: Near it is a star of 8th magnitude. M. Messier reported its position on the Chart of the Comet observed in 1773 & 1774. Memoirs of the Academy 1774, plate III. It is double, each has a bright center, which are separated 4'35"". The two ""atmospheres"" touch each other, the one is even fainter than the other. Re-observed several times."

E. of Rosse's wonderful spiral; its wreaths are beyond all but the first telescopes; common ones will only show two very unequal nebula nearly in contact, both brightening in the centre: traces of the halo encompassing the larger may be caught; Sm. could not do more; 'The enigma is another unequivocal mark of the illimitable power of the Supreme Creator!' 9-1/3 in. speculum showed plainly outer end of spiral and junction with smaller nebula. A misty spot in finder 3° sp, Alkaid, at end of Great Bear's tail.
