Description:
NGC 1792:
Even though it has roughly the same size as nearby 1808, NGC 1792 does not look 
as bright at all. The 5x2' patch of nebulosity does not even show any signs of 
a center or core. It is plainly structureless. A very faint star is located 
just at the W edge of the galaxy close to its middle. Unspectacular.

NGC 1808:
Bright edge-on galaxy in Columba at -37°. At 131x it streches over approx 
5x1,5' and shows an elongated bright center. Nice.
