The faintest Dunlop galaxies are: NGCs 1487, 7689, 1483 and IC 1633 with magnitudes 11.4, 11.4, 12.3 and 11.6 respectively. Below is a map from SkyMapPro for 4am showing his faintest galaxy NGC 1483 near the center and 1487 near the top.
On 3/12/1837 John Herschel wrote reagarding h2595 = NGC 1483 "I feel convinced this nebula is too faint to have been seen by Mr. Dunlop. Put on the 9" aperture, could not discern the least trace of it. Mirror polished yesterday and in high beauty. Sky Superb."
In 1826 James Dunlop described D428 = N1483 as "An extremely faint ill-defined small nebula. A pretty large nebula (NGC 1433) precedes this." Did Dunlop see N1483. What do you think?
