Glenc has done a lot of academic work on James Dunlop, the fellow who operated the Parramatta Observatory. Glen has also started many threads promoting Dunlop, his discoveries and the Parra' Obs.
This particular thread focuses on historically significant sites, and the Parramatta site is one of them - see post No. 3.
The discoveries Dunlop made of DSO's is confirmed with the nomeclature of his discoveries with the list of The Dunlop Objects. Glen has written an article on
The Dunlop Ojects.
If you are interested in the Parramatta Observatory, drop Glen a PM.
On a side note, one of Glen's threads deals with which of the Dunlop objects are best placed in the sky at a given time of the year. I'm contributing sketches I make of the Dunlop Objects as I go along. I'm struggling to find the thread though,
