How to find HD 10498 in the sky
HD 10498 lies in Perseus. With a declination of +51° 31.0', it is visible from the entire Northern Hemisphere and from the Southern Hemisphere down to about latitude 38° S. Observers poleward of latitude 38° N see it as circumpolar: it never sets. It is just beyond naked-eye visibility; binoculars will show it easily. It is highest in the sky at local midnight around November, which makes the weeks around that month the best time to observe it.
