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

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

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 ?

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

Well Done Ron! :thumbsup:

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

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:thumbsup:

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 !

Nice photo Davo!:thumbsup:

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

:hi: 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:thumbsup: :astron: :stargaze:
