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.
