Its the star called Mirach it is a red giant about 450 times more luminous then our sun at mag 2 and 200 ly from us in the constellation andromeda. Because of its brightness the galaxy (ngc404) on its side 5 o'clock position it is difficult to see and hidden from the reflection of the star and its 11 mil. ly further at mag 10 from us. To image it took some trial and error until the light reflecting into the mirror optics was to a minimum at this frame-up.
