    These observations were made with my 24" in late Sept. 2019 with an SQM reading of 21.3.

    IC 1756: Very faint, edge-on 4:1 NNW-SSE, ~40"x10", low even surface brightness, no core. A mag 14 star is at the southeast edge and the galaxy is a dim streak extending mostly NNW from the star. A mag 13.7 star is 1.7' SW.

    IC 1757: Extremely faint, very small, 10" diameter, low even surface brightness. Required careful averted vision to hold for an extended period. Situated just 1.5' E of brighter IC 1756.
