Dunlop's house
I used to think that Dunlop made his catalogue of clusters and nebulae from his house on the north side of Hunters St, half way between Marsden St and the gates to St Johns.
Now I think he made his catalogue from 91 Marsdens St because
1. He says in his notes that he move to Elders house (see below)
2. He says in his catalogue that he observed from 6" south and 1.78s east of the observatory. (see below)
3. A 1904 map shows that he and others owned a block of land there. (see below)
4. The Elders were fellow Scots.
5. The Elders seem to have named their daughter Eliza Dunlop Elder after him.
Prior to 1840 only three men found more than 100 star clusters, nebulae and galaxies - Sirs William and John Herschel and Dunlop. I would like to see a plaque in Parramatta commemorating his work.
