These 16 deep sky objects transit between 8pm and 10pm in September.
They were selected from the best 150 objects in the All Sky Messier Catalog.

Awesome Glen! Thanks for that.

Attached is the file with all 150 objects, 140 of them are south of declination +50. There are 25 OC, 25 GC, 25 Neb, 25 PN and 50 galaxies.
The spreadsheet gives the month for 10pm.
The August objects transit at about 8pm in September.
The October objects transit at midnight in September.

Glen,

I just would like to say big THANK YOU!
I always use your monthly files that you post here as a guide what to view.

Well done mate.

Thank you Leon, Marc and Bob.
The attached file is a summary checklist.
You can cross them off as you see them.

Last night I saw 49 of these 150 DSO with my 12" Dob between 1am and 3am. Started with the PN NGC 7009 and finished with the OC NGC 2547.
Clouds rolling in the from the NW were a problem, I could have seen more if it had been clear.

I've started to run out of Messier objects I haven't had a go at imaging, so moving over to having a work through your ASMC now Glen.

Thanks again for the effort put into this!

The sky was dusty last night but I managed to cross off some more objects from my list of 150. A 12" Dob was used to view through the murk.
I have now seen 88 (59%) of the 150 DSO. The smallest one was the PN NGC 6629. http://picasaweb.google.com/dunlop18...91958461455026
At 2am this morning I caught the double cluster NGC 869/884 transiting just above my northern horizon.
If it is clear tonight I will fill in some gaps by seeing M13, N6210, M92 and N6826.

Hello Glen,

I'll bet you were glad you observed last night. Tonight's transparency would be -5!! I was going to have an observing session last night, but the murk and the searchlights on the sports fields not far away kept me inside. eEven Scorpius was beginning to fade!! Cheers, Paul.

glenc (Glen) · #11 23-09-2009, 05:13 PM

Paul, visibility was down to less than 1km here today and the Moon is getting brighter so I might have to wait to see M13 again.

Lismore Bloke (Paul) · #12 23-09-2009, 08:51 PM

Yes, the moon will become more of an issue in a week or so.

The sad thing about this dust storm is not the inconvenience to amateur astronomers, that will pass. The loss of the best and most nutrient-rich top soil layer in some of the oldest and most fragile soil profiles in the world is something that will not be fixed in a few weeks. Having driven through that country on the recent outback trip really drives the point home. Very sad.

glenc (Glen) · #13 25-09-2009, 06:03 AM

Yes it is a terrible loss of soil.
It was VERY clear this morning. I have now seen 110 of the 150 objects in this list. The remaining 40 are close to the Sun now, or too far north for me to see.

I notice Roger Blake used one of my lists in his book.
http://messier.obspm.fr/xtra/similar/cozens.html

The book " includes a master list of virtually all the best objects in the entire night sky (+90º to -90º declination) with large, high resolution images of every single object.
The images include all of the 900+ objects listed in the 7 most popular observing catalogs (Messier, Caldwell, SAC, etc), 200+ Herschel objects, plus 90 additional new objects chosen by this author."
