H-NGC4111
Galaxy in Canes Venatici
About
A lens-shaped galaxy in Canes Venatici, seen nearly edge-on, with sources giving 43 to 50 million light-years. Dust filaments run across its core perpendicular to the disk, probably tied to a ring of material left by a smaller galaxy it absorbed. It leads the NGC 4111 group and is in the Herschel 400.
Imaging tips
- About 5′ by 1′, so it is too small to frame: use a long focal length and a fine pixel scale.
- Surface brightness is 21.2 mag/arcsec², under the roughly 22 level that counts as faint, and the galaxy suits broadband imaging.
- About 9′ to the east-northeast (approximate, from coordinates) sit NGC 4117 and NGC 4118, so a wider field takes in more of the group.
- Best in March and April; it peaks near 83° from 50°N.
