600/800mm - 24" (2/13/18): at 375x; very faint, very thin streak, ~40"x5". UGC 4133 is the fainter of a very close pair with UGC 4134 just 1' SSE of center. On images this extremely thin edge-on stretches 2', but I only picked the brighter central region and not the outer tips. In fact, initially I didn't notice this galaxy as I assumed it reached right to the southwest edge of UGC 4134.

900/1200mm - 48" (2/28/19): at 488x; beautiful extremely thin edge-on 10:1 NNW-SSE, moderately bright, 1.6' x 10". Contains a small bright core and stellar nucleus. Forms a striking pair with UGC 4134 1' SE.
