Faint but easily located beside M31, small, faint patch 1° northwest of the core of M31

It is interesting to consider M110 for itself, ignoring the presence of M31 just outside the field, large, diffuse, small and stellar core just visible, elongated N-S, several faint foreground stars involved with the halo

Large faint oval neb. best with low powers: res. by Bond: a very large field includes it with NGC221 and NGC224. Seems to sparkle; much more oval and less spindle-shaped than as drawn by Bond.

150mm f/17.6 refractor by Tully 1827

A large faintish nebula of an oval form, with its major axis extending north and south. It is between the left arm and robes of Andromeda, a little to the np of 31 Messier; and was discovered by Miss Caroline Herschel in 1783, with a Newtonian 2-foot sweeper. It lies between two sets of stars, consisting of four each, and each disposed like the figure 7, the preceding group being the smallest; besides other telescopic stars to the south.

This mysterious apparition was registered by William Herschel as 30' long and 12' broad, but only half that size by his son; and there was a faint suspicion of a nucleus. This doubt must stand over for the present, for whatever was a matter of uncertainty in the 20-foot reflector, would have no chance of definition in my instrument. It was carefully differentiated with Andromedae.

Very bright, much extended, 30' long, 12' broad, discovered by Caroline Herschel.

William Herschel

There is a very considerable, broad, pretty faint, small nebula near it [M31]; my Sister [Caroline] discovered it August 27, 1783, with a Newtonian 2-feet sweeper. It shews the same faint colour with the great one, and is, no doubt, in the neighborhood of it. It is not [M32] ..; but this is about two-thirds of a degree north preceding it, in a line parallel to Beta and Nu Andromedae.
