, and every one we have seen credits Darquier.
The first image in the Messier catalog
, called M1, was that of the Crab Nebula, which Messier mistook for the Halley's Comet - his inspiration for creating his catalog.
8) At 3,600 light-years, M93 is one of the more distant open clusters in the Messier catalog
Since Messier's time the Messier catalog
has developed and matured, in several stages.
It's plausible that Mechain was in fact describing NGC 5866, and identifying M102 with this galaxy nicely fills out the Messier catalog
During that brief period, it's possible to log all 109 objects in the Messier catalog
in a single night.
Spiral galaxy M109 in Ursa Major sports one of the most distinct central bars of any galaxy in the Messier catalog
Indeed, this 8th-magnitude object holds the distinction of being the most elusive open cluster in the Messier catalog
According to the website cited above, the Herschel Catalog is considered less reliable than the much smaller Messier Catalog
in terms of duplications and other errors.
Indeed, of the 39 specimens in the Messier catalog
, only two are much more than tiny blurs in ordinary binos.
Lying some 68,000 light-years away in Sagittarius, M75 is the second most distant globular cluster in the Messier catalog
ALTHOUGH GALAXIES dominate the list of deep-sky objects in the Messier catalog
, they're also the most difficult to observe.
