11.4cm f/4 Newtonian, Kinipōpō @ 18x
Seeing: 7 Transparency: 7 Moon: 0%
Bright and obvious but notably fainter than the nearby M81, 10'x 5' elongated northeast to southwest, a modest nucleus surrounded by a ghostly halo, M81 visible ½° south, the view nicely matches the 1774 description of Johann Bode using the little RFT

46cm f/4.5 Deep Violet
Very large! Very bright! a mottled cigar shaped galaxy elongated 6:1 E-W. A lot of detail in the halo with large brighter regions, no obvious core or nucleus.

Two neb. ½° apart[M81 and M82]; 81 bright, with vivid nucleus, finely grouped with small stars, two of which are projected upon the haze, to which h. gives nearly 15' of length. Two little pairs sp, making the field very interesting. The nearer is Σ1387: 9.5, 9.5: 269°.6: 8".9; the further is Σ1386: 8.2: 8.2: 296°: 2". 82 (Bode's neb.), curious narrow curved ray. D'A., 7' x100", two nuclei, and sparkling as if resolvable, which 81 is not. Huggins finds both spectra continuous, but deficient at the red end, like the Androm. neb., etc. L.P., spiral; spect. one absorption and two bright lines.

A very bright, beautiful ray of light, about 8' long, 2' broad; brightest in the middle of all its lengths. Follows 27 Ursae 14m 12s, and is 2° 27' south of that star.
Jan 6, 1780
Nebula without star, near the preceding [M81]; both are appearing in the same field of the telescope, this one is less distinct than the preceding; its light faint & elongated: at its extremity is a telescopic star. Seen at Berlin, by M. Bode, on December 31, 1774, & by M. Méchain in the month August 1779.

Dec 31, 1774 Berlin Observatory, Germany (map)
On December 31, 1774, I found through the seven-foot telescope, closely above the head of UMa, east near the star d at its ear, two small nebulous patches separated by about 0.75 degrees, the positions of which relative to the neighbored small stars are shown in the tenth figure. The patch Alpha (M81) appears mostly round and has a dense nucleus in the middle. The other, Beta, on the other hand, is very pale and of elongated shape. I could determine the separation of Alpha to d as 2°7', to Rho as 5°2' and to 2 Sigma as 4°32' with some acuracy; Beta was too faint and disappeared from my eyes as soon as I shifted apart the halves of the objective glass.
