This picture shows you a dimmed edge-on galaxy of NGC4244 at the western part of Canes Venatici. You can find out the galaxy at 7.5 degrees west from alpha Canum Venaticorum, Cor Caroli.
The galaxy has a thickness of only a bit smaller than 2 arc minutes while a length of 16.6 arc minutes. This size exceeds that of NGC4565, one of most popular edge-on galaxies in the constellation of Coma Berenices. But NGC4244 has a visual brightness of only 10.6th magnitude, it might be needed a medium-sized telescope with about 6-inches in aperture to enjoy this faint galaxy. We're appreciating the galaxy from almost dead side, and can hardly detect the central bulge region and dark lane.
