John Herschel recorded it as "B, S, R, pmbM, 20 arcseconds." On a second occassion he called it "pB, S, R, gpmbM, 15 arcseconds." His third observation was recorded as "vF, S, R, psbM, 20 arcseconds, very dilute at the borders."

24" (4/5/08): at 260x appears moderately bright and large, elongated 4:3 SW-NE, 1.2'x0.9', broad concenctration. This starburst galaxy contains a super-star cluster (SSC 1750-A) that appears as a 14th magnitude "star" offset to the west of center. In good seeing at 350x using the 13mm Ethos and a 2x barlow, the SSC just west of center was easily visible and generally appeared stellar, though at moments there was an impression it spanned a couple of arcseconds. A short string of four faint stars is collinear to the NW. Located 30' ENE of the bright double star Iota Pictoris (5.6/6.4 at 12"). N1705 is a nearby blue dwarf starburst galaxy at a distance of 17 million light years.

This faint round galaxy is situated a mere 30' east of the lovely double star Iota Pictoris. Slightly elongated in an NE-SW direction. The nucleus is bright and with time come and go like an out of focus star.
