I am not impressed with today's APOD of 47 Tuc :sadeyes:

http://apod.nasa.gov/apod/image/1212/47tuc_ederL.jpg

It is washed out in the core:shrug:
In this day and age I don't think this should be :rolleyes:
I have seen many better images posted on this forum.
APOD IMHO standards are slipping,as I really don't think this image deserves that accolade.:question:
Cheers:thumbsup:

Unless you're in the in crowd (regular recipient or a member of TWAN, etc.), it's very hard to break through and get an APOD.

You really need to submit something spectacular to get noticed.

For most of us mere mortals, we'll never see an accolade.

well it does show lots of other globs ;)

i agree but i am so photon starved that this look good Ron

H, do you think my criticism warrented,what do you think of the image:question:
Cheers:thumbsup:

I acknowledge your comment about the washed out core, but the context of 47Tuc beside the edge of the SMC (I presume) gives the image scale and I like it.

Ron,

Ivan takes beautiful images with his DSLRs. He travels to Namibia (from Hungary) to capture a lot of his stuff.

I think, despite the criticism, he's deserving of featuring on APOD.

David, surely other imagers have taken the same image without the blown out core:shrug:
I reckon if I felt inclined,which I don't I could trawl through the Deep Sky section of iceinspace to find images that showed the scale very well,and without the core of the cluster being blown to smitherines.
Cheers:thumbsup:

I except your knowledge in all things to do with imageing H but don't think this deserves the APOD:thumbsup:

More care should have been taken with the processing so as not to burn out the core.
It doesn't look like 47Tuc to me when it is presented like this.

[astroron]

Thanks JJJ :thanx: I am glad someone sees what I see ;)
To me it could be any tight Globular Cluster taken about twenty years ago or more ago when people used film :(
Cheers:thumbsup:

I believe the image is ideally processed.
The core isn't burnt out, it reflects the high concentration of stars near the centre.

The concentration of stars is classified on a scale of 1-12 where the lower the number the greater the concentration.

47 Tuc is classified as a 3.

Whole heartedly agree with you. The site is Astronomy Picture of the Day not an award for "Struggling with a DSLR in Africa" and a lifetime award for struggling.
The burnt out core is just bad image processing - the rest of the frame is OK but Ive seen far better.
Just my opinion, Allan

I happen to really like this pic... my guess is that it was chosen for its unique composition. It's different to what you usually see, such as all these very similar looking images of 47 Tuc (http://images.google.com/search?num=10&hl=en&site=&tbm=isch&source=hp&biw=960&bih=982&q=47+tuc).

If we're willing to accept "visible" light images with drastically different response curves to the average human eye (especially H-a sensitivity and lack of colour with low light levels), drastic tone mapping for dynamic range, etc... then why not let the core burn out a little to show that it's a *LOT* brighter than the surrounding sea of stars? :)

Side note: the Google search for visually similar images (http://www.google.com/search?hl=en&tbo=d&bih=985&biw=960&tbs=simg:CAESXxpdCxCo1NgEGgQIAAgDDA sQsIynCBo0CjIIARIMrwe9B7AHwQewBLkDG iDluiCUqmXXhuApjbKcdoZz11JDCmGrU4qm SW1ovrDkuAwLEI6u_1ggaCgoICAESBNtrZu kM&tbm=isch&sa=X&ei=iYrBUNDFIYSfmQWi6oGoDw&ved=0CE8Qsw4) is hilarious... I think some of those reflect people's feelings about this as an APOD! :rofl:
