03/07/14
A distinctly misshaped blob with no central brightness but rather bright patches although still only a haze in 12mm
There is just a hint of NGC 4485, the Mag 12.0 Galaxy which NGC 4490 appears to be interacting with
Both are in the same 25mm FOV as B CVn, or 8 CVn, HIP 61317, the Mag 4.20 star known as Chara
Chara appears so bright in the FOV as to be dazzling1

The Cocoon Galaxy
Very easy to locate this pair (with NGC 4485) of interacting Galaxies since they sit in the same 24mm FOV as Chara, B C Vn, 8 C Vn, HIP 61317 which at Mag 4.20 is the second brightest star in Canes Venatici and indeed there only seem to be two to the naked eye!
NGC 4490 appears to have an irregular shape, quite faint but with a slightly brighter line at its core
The much fainter NGC 4485 at Mag 12.0 is only just hinted at at one end
