This star forms a wide
triangle with I and S Eri and is impressive. A comfortable 2.8 and 3.9 pair at a wide 8.3" makes a beautiful White and Light Blue combination at low power. Unfortunately is lies 40º South. Always willing to be diverted under the starry dome, at this stage I was coaxed over the border to Fornax where I managed to pick up two glowing star cities in the Fornax 1 Galaxy Cluster. The large(8.1' X 7.6') NGC 1399 glowed clearly as a slightly oval mag. 8.8 object, while the fainter NGC 1387 at 10.8 mag. and 3.1'X 2.8'was faint but obvious. Back to the doubles.

Also catalogued as Dunlop
9 and Piazzi 2. Known as Acamar, was the
river’s end in ancient times. A splendid pair, a gem of the southern
sky and
one of the best in the whole heavens, and in my opinion the most
beautiful in
Eridanus.
Theta itself has very bright components, quite close, both stars brilliant white or slightly greenish, sometimes this pair remembers Mizar to me. Yet split at 32x, it looks better at 54x and 80x.
