Saturn and its Serpent Storm still impressive after five months and the moons Tethys and Rhea could be seen also.

I'm always happy to see rarely photographed objects being portrayed, so I was very happy to see Günter Kerschhuber's portrait of UGC 4305, Holmberg II. Note the fantastic "garland" of star formation regions along the left edge of this dwarf galaxy. Do follow the link to Günter's homepage, by the way, where you can see the full resolution of this picture and see the contrast between the underlying smooth low-mass population of this galaxy and its population of bright high-mass stars. This contrast shows up even better because Günter has included a black and white image of UGC 4305. It looks a bit like a smooth sand structure irregularly overlayed with discernible pebbles!

I like Steve Allen's picture of M63, too. Note the huge tidal structure or outer arm originating at the lower left of this galaxy and arching upwards and inwards. This structure is clearly made of dust and low-mass stars. Also note the outlying blue patch of young stars to the lower right.

IC443: Supernova Remnant in Gemini and Surrounding Field

[attachment=2]GEM-IC443-1600.jpg[/attachment]

This field has everything: a supernova remnant, subtle HII areas, three reflection nebulae of three different colours (find the third one!) and some dark clouds. Hints of dust can be found around the edges of the nebula. It also sports two very bright orange stars (μ and η Geminorum) that required some heavy duty thinking!

I went to the workshop that taught Adam Block in Mount Lemmon. He gave us the material of some images, including that of M51.
So the data capture is by Adam Block with the 1m telescope at the University of Arizona is located in Mount Lemmon, Az. and processing in this case, mine.

Iván Edér's image of M106 and its neighbourhood is fantastic. Thanks to Owlice, who posted the really large version of the image elsewhere, but since I wouldn't even presume to count the galaxies in the image, I want to post my comment here. There is "an embrrassment of galaxies" here, except there isn't, of course, since the expression "embarrassment of riches" apparently means "too much of a good thing". Well, there aren't too many galaxies here, but there sure is a wealth of them. Amazing.

As a color freak, I'm almost floored by the effect of the juxtaposition of the two most strongly colored objects here, a blue and an orange star right next to each other some distance away from the second most obvious galaxy in the picture, NGC 4217. And amazingly, as I checked the stars with my software, the blue star really is a B-type star with a quite strongly negative color index, and the orange star really is a red star with about the same spectral class and color index as Aldebaran.

Closer to NGC 4217, and to the upper left of the striking blue and orange pair, is a neutral-colored even brighter star. This is a G-type star, admittedly a G5 star instead of a G2 star like the Sun, but the color of the G5 star is relatively similar to that of the Sun.

Overall, Iván Edér's image is relatively softly colored, but thanks to the brilliantly colored pair of stars it is nevertheless sparkling with color. His picture invites us to consider the nature of galaxies: they are, by and large, a collection of stars of different colors: white, orange and blue stars and stars of all possible hues and nuances in between. These stars are like tiny, tiny coloring-brushes. Together they paint the sky with soft color and make it sparkle.

Thanks a billion to Iván Edér for bringing this splendid image to us.
