De Vaucouleurs Atlas Description:
This is another large bulge, edge-on Sa galaxy with a strong planar dust lane. This galaxy is more edge-on than NGC 4594 , but the appearance of the dust lane suggests an inclination still slightly less than 90o. The near-side dust lane is very sharp in the B-I color index map, but the doubling on the northwest side could be the dust disk curving around to the far side. Extinction prevents the nucleus from being seen.
NGC 7814 has been the subject of several studies concerned with the properties of bulges. For example, Jarvis and Freeman (1985) analyzed photometry and kinematics of the bulge, and concluded that its properties are consistent with being an oblate system flattened mostly by its rotation. They were also able to detect the impact of the weak disk component on the rotational properties of the bulge.
