Here are the Dunlop objects for September and October at 10pm (11pm DST)
There is one globular cluster (NGC 104 = 47 Tuc) and 14 galaxies.
The faintest galaxy is NGC 7689 magnitude 11.7. Size is in arcmins.
Dunlop's House was on the north side of Hunter St half way from Marsden St to the church gates.
He catalogued 629 clusters and nebulae and 253 double stars from his backyard in 1826. http://binged.it/Rlffxw

It's "first come, first serve". Once it is used five times, it stops.
the venerable Hubble Space Telescope delivered holiday cheer in the form of this image of NGC 5189, a nebula that — if you're brimming over with holiday cheer or just squinting a little — resembles a very merry Christmas ornament wrapped in a festive ribbon.
Here's the latest batch of Dunlop Objects that I've managed to sketch. These are all located in a small area within the LMC.
The Dunlop objects here are:
NGC 1850 - Dunlop 172
NGC 1854 - Dunlop 119
NGC 1858 - Dunlop 120
NGC 1856 - Dunlop 118
NGC 1860 - Dunlop 172
NGC 1863 - Dunlop 173
NGC 1866 - Dunlop 247
NGC 1870 - Dunlop 123
This sketch was done during the Jan. '13 new moon period from Katoomba Airfield using a 17.5" dob at 100X. I've also included an image by Andrew Lockwood of the LMC showing the area the sketch is focused on.
Deep-Sky Companions: Southern Gems is due out this month.
"In Southern Gems, Stephen James O'Meara makes a detour beneath the southern skies, presenting a fresh list of 120 deep-sky objects for southern hemisphere stargazers to observe.
Showcasing many exceptional objects catalogued by the pioneering observer James Dunlop, known as the 'Messier of the southern skies', all are visible through small- to moderate-sized telescopes or binoculars under dark skies." http://www.cambridge.org/us/knowledg...e_locale=en_US
"Here's a treat for southern hemisphere observers - the 'Dunlop 150' observing plan has been uploaded to the Plan Library.
These are objects observed in 1826 with a 9" speculum metal reflector by James Dunlop of Australia" https://www.facebook.com/deepskyplanner
220 years ago James Dunlop was born at Dalry, Scotland on 31 Oct 1793.
In just 7 months in 1826 he catalogued 629 star clusters and nebulae. Half of these turned out to be faint (m11) double stars.
He also made a separate catalogue of 253 double stars the same year with his homemade 9" speculum reflector from his Parramatta back yard.
Dunlop died aged 54 on 22 Sep 1848 and was buried at Kincumber, NSW.
First, Dunlop 25 & 31 - NGC 346 and 371. These two nebula and open cluster objects are within the SMC. Both are surprisingly bright, particularly Dunlop 25. The stars powering this cluster and nebula must be very big suckers to appear so bright being so far away. This sketch was done using my 17.5" dob at 154X.
The third object is Dunlop 562 - the brilliant barred spiral galaxy NGC 1365 in Fornax. In my 17.5" dob the bar and arms are striking. Increasing the magnification to 154X increases contrast and improves the visibility of the arms and the details. This is a trick that works with most DSO's.
Hi Glen,
thanks for bring the Dunlop list to my attention. I'm a Hartung southern objects man myself! I'll load the Dunlop list into the G11 hand controller and go explore. How did your manage to graph the Dunlop objects in excel? What type of chart is that? thanks
Regards

Alex, how long have you been sketching for? Your drawings are incredible and some look like they must take hours to complete, such is the detail.
How did you learn your technique - books, or trial and error? I have done a little, but want to get into it more seriously than what I have done to date.
