John Herschel discovered NGC 1826 = h2757 on 20 Dec 1835 and recorded "vF, 20", the following of two [with NGC 1822]." Steinicke lists Dunlop as the discoverer (D 235) of this object as well as NGC 1822, though Dunlop's position is much closer to NGC 1818, which may have multiple entries. I think this pair of clusters is too faint to have been picked up by Dunlop.

600/800mm - 30" (11/4/10 - Coonabarabran, 264x): slightly brighter of a pair of small clusters with NGC 1822 2.8' NW. Appeared moderately bright, round, 45" diameter, broad weak concentration but no resolution. A mag 10.8 star lies 2.9' E.
