Ufda!

And now for something new, not an amateur image but striking and something to strive for, taken with the Danish 1.5 meter scope at LaSilla, Chile:

(I wonder what the FWHM of that image was)

Wow, that is awesome! Thanks for posting! And I thought mine was pretty good (from my measly ST8XE and 12.5" f4 newt from the Lockwood Valley in So Cal :-))

HOLY CRAP!!! That is impressive. Thanks for sharing Roland - just simply staggering the level of detail.

cheers,

Roland: That is a wonderful image... But here is a question for you and others:

At full resolution, I see a "certain graininess" to the image, rather than smooth nebulosity gradients. What is going on here? Here is a small portion of the image at full posted resolution:



I am curious because I see what appears to be the same effect in some of my images.

Thanks

What makes me cry are the exposure times.
Although this one is a long one at 10--10--10 minutes, a lot of his LaSilla images are only a minute long or so in each channel.
