I have to start off by noting that one of my all-time favorites, Adam Block, is back. I'm eteernally grateful to Adam for his amazing dedication in photographing so many different astronomical objects, not least galaxies. If you want to see an image of a particular galaxy, chances are you'll find it here: http://www.caelumobservatory.com/obs/bestofaop.shtml.
Anyway, Adam has posted two images here, and me being me, I am of course happiest about his galaxy image. NGC 266 is one more of those not-so-often-photographed galaxies, so it's great that Adam has imaged it. NGC 266 is one of those galaxies with a braod bright yellow bar and thin, elegant, blue spiral arms, which are clearly winding down in star formation activity. In my opinion, the fact that there is so little star formation in this galaxy is a likely contributing reason for it being so elegant and symmetrical.
Of course I like your image of globular cluster NGC 2419 too, Adam. I particularly like how well your image shows the bright orange-colored Asymptotic Giant Branch stars in NGC2419 (these are red giants at their very brightest, just before they start shedding their atmospheres and turning into planetary nebulae central stars), as well as the "intermediately-bright" blue horizontal branch stars, which can form only if the stars they start out from contain very low levels of elements heavier than hydrogen and helium.

I know exactly what you mean, Adam. Your new images are much better than your old ones, which are, however, also good. But what makes the old gallery so interesting is that there are 260 different galaxies there, and there are far fewer in your most recent gallery.ngc1535, Adam Block, wrote:
Thanks Ann. Please do refer to the most recent gallery of images I am producing at the Mount Lemmon SkyCenter (http://Skycenter.arizona.edu). Galaxies, for example, can be found here:

Hopefully more images to come soon...
Now that this telescope will be available for remote observing, I suspect the rate of images produced will exceed past efforts in the coming months (and years).Ann wrote:I know exactly what you mean, Adam.

But I, too, very much look forward to seeing more galaxies in you most recent gallery!
