Whats this near 47 Tucanae?

Anyone know what the blur in the bottom left corner is?

NGC 121, I would like to bet. A 10th Mag open cluster !

Davo3960 · #3 22-08-2006, 10:49 PM

Thanks Ian. Mystars! does not go further than mag 10. Might have to upgrade the star chart software!

first of all is this a dslr shot, if it is then maybe some internal scope or lens reflection from the bright glob ?

Davo3960 · #5 22-08-2006, 10:53 PM

Possibly Houghy but I've never seen it on any other shots. Yes it is a DSLR shot.

I agree with Ian

From CDC:
NGC 121 - Globular Cluster in Tucana
Dimesion 1.5' x 1.5'
Mag: 10.6

And is marked on Taki's 8.5 Star Atlas (even though it is 10.6) but not labelled.

Excellent find Dave!

After comparison with a very good image with all the ngc objects close to 47Tuc I have worked out to be Ngc152 and has a given mag of 12p, Ngc 121 is on the other side, not visible in your image

ballaratdragons (Ken) · #8 22-08-2006, 11:27 PM

Well Done Ron!

NGC152 isn't shown in any of my programs or maps.

astroron (Ron) · #9 22-08-2006, 11:39 PM

Thanks Ken , there is another cluster in the photo which looks like a double star, which is closer to 47Tuc, which is Ngc 176, both at 12th mag

gaa_ian (Ian) · #10 22-08-2006, 11:43 PM

I'm going to stick with my version (sorry Ron ;-) ) the asterisms of stars around NGC 121 match those in Davos photos (Starry night Pro)
I will of course have to add this to my Obs list for the W/E now !

astroron (Ron) · #11 22-08-2006, 11:57 PM

Ian try this for size

ballaratdragons (Ken) · #12 23-08-2006, 01:02 AM

Oh, and by the way,

nice photo Davo

sheeny (Al) · #13 23-08-2006, 12:55 PM

Nice photo Davo!

And good detective work, the rest of you! Astroron, I think I agree with you based on the asterisms in your image. Well done!

Al.

Davo3960 · #14 23-08-2006, 08:31 PM

Looking at the attached image I have to agree with you. Excellent work. Thanks Ron.

Davo3960 · #15 23-08-2006, 08:36 PM

Whoops. Now it's attached.

gaa_ian (Ian) · #16 23-08-2006, 10:50 PM

OK Ron, I will go with you

Gotta have a look at this one 4 sure now !
This is a great way to learn new NGC's

Great detective work guys. And an excellent shot of my favorite Glob. Thanks for posting it.

astroron (Ron) · #18 24-08-2006, 01:30 AM

I have just come in from observing all three objects, and I have to reverse the two numbers

, the object in question is ngc176

, the object and the asterism are quite distinct in the eyepiece on the image I attached Ngc 152 is covered by the number,this object is bigger but duller.
It was a good exersize in observational and chart reading which everybody enjoyed
