The Grus Quartet and thousands of distant galaxies!

This has been the project over the last two imaging sessions. Although it is a relatively popular target I haven't done a colour image of this group since 2005. I managed to get 6hrs over two nights and went reasonably deep (for a 6" anyway) and the seeing finally was better than average for a change, not great but not bad at least
The wide field view is actuallu about a 50% crop of the original full chip image, would have just got lost in the frame otherwise, still I think the resolution holds up ok..? I think there may even be more galaxies in this image than stars

If you are on dial-up or have a low usage BB account, when the image starts to download from the links below scroll down to the bottom of the page and hit "large" in the other sizes menu, this will open a much smaller version so you can decide whether you wish to open the "original" and much larger size image

I'm happy with how these turned out so I hope you enjoy looking at them, again I recomend hitting F11 on your keyboard for a more unobstructed full screen view when you open an image

Here is the low res but full frame "fits perfectly on a 21 inch monitor" version (1.3meg)

Well worth a detailed scan, here is the full size full res version - with many galaxies and galaxy clusters in the background (3.4meg):

Here is a zoom in on the three main galaxies and again showing lots of background galaxies (1 meg):

Lastly this is a close up of the outer member of the Quartet - NGC 7552, I love the shape of this galaxy (300K)

In a small section of the frame I found these distant galaxy clusters too, if anyone can identify these would be cool, cropped from top left corner of full image:
