Barred Spiral Galaxy Messier 91 in Coma Berenices
Messier 91 is a barred spiral galaxy and is classified as anaemic - this means that it has been subjected to ram pressure stripping as it races through the hot intracluster medium of the Virgo cluster of galaxies. It loses the gas it needs to form young hot blue stars so appears pale and yellowish as a result.
It measures 5.4 x 4.3 arcminutes.
26 x 10 minute subs. Modified Canon 80D at ISO400 on an Equinox 120ED doublet refractor.
See previous wide field for more details.
