Type: galaxy (in cluster), E...
Mag: B=11, V=?
Size: 5.011′ x 3.801′
In the Appendix to the 1912 'Scientific Papers of Sir William Herschel' this object is described as "1784, April 17. pB, R, nos small, mbM."
Sketched and described.
A supernova erupted in this galaxy in 1939 (12.7p)
(Sulentic and Tifft 1973) notes that this is a 11.5 mag galaxy. Their coded description reads BE,SLEL,BM.
Lorenzin, in the e-version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "11.4M; 2' diameter; round and bright with brighter center but non-stellar nucleus; !good supernova prospect!; SP GAL N4606 (12M; 2.8' x 1.5' extent) 22' to NW is overlain with 13M stars."
Instrument:12-inch Dobsonian Reflector Telescope.
Sky Conditions:The fainter parts of the Milky Way are barely visible.
Transparency of the Sky:Haziness only visible on the horizon.
Seeing:Atmosphere stable with little interference.
First Impression:This object looks like an elliptical galaxy.
Chart Number:No.173(Extract taken out of "Star Gazer's Deep Space Atlas").
Size:26mm Super Wide Field Eyepiece:Field Of View:57'/12=4.7'.
20mm Ultra Wide Angle Eyepiece:Field Of View:50'/10.5=4.7
4.7'+ 4.7'= 9.4'.
Size in Arc Minutes:4.7'.
Galaxy is 4.7'* 1.5'.
Brightness Profile:The central nucleus of this galaxy grows brighter in the middle of the galaxy compared to the far outskirts.
This galaxy has a fairly strange round shape.It also has a bright nucleus.The galactic nucleus is strongly concentrated in the middle.
Observing site: Pinnacles overlook
[12h 42m 0s, 11° 39m 0s] AKA M 59. Like a fuzzy star. Small but bright. I suspected it was a Seyfert, Burnham notes it is a massive elliptical, but considerably smaller than the milky way.
