Nice sketches, Jeremy.
Thanks for sharing.

Jaime.

Hi Ann, thank you!

It's fascinating how subjective color perception is at the eyepiece. Sometimes when doing outreach observing, I'll point the scope at Albireo and ask visitors to look at the stars and tell me what colors they see. Some see the gold/blue combo well, while others see color in only one or the other of the stars, and then some see no color at all.

Doubles in the Struve catalog that don't have a Flamsteed/Bayer designation can be a pain to find sometimes. Struve 747 can be found at [url=http://simbad.u-strasbg.fr/simbad/sim-id?Ident=sao+132301&NbIdent=1&Radius=2&Radius.unit=arcmin&submit=submit+id]05 35 02.682 -06 00 07.30[/url]
The A/B Components are catalogued as:
HD 36960/36959
SAO 132301/132298
ADS 4182

I hope you get a chance to take a look!

Jeremy

Thank you for your lovely sketches, Jeremy Perez!

You captured exactly the grey-green color that I myself have seen in M42. Thank you!

As for blue stars, many blue stars look as intensely colored to me as the blue component does in your sketch of STF 747. What star is that, though? Do you have an HD or an SAO designation for it, or at least some good coordinates?

To me, Lambda Orionis looked exactly as blue last time I observed it as the blue component of STF 747 apparently did to you! I agree with you, though, that Rigel, for some reason or another, often doesn't look very blue.

Anyway, thank you very much for your delightful sketches!

Ann

Hi, this is my first submission here. Although I shoot wide field images from time to time, I'm primarily a visual observer and sketch the wonders of the deep sky as I view them through my telescope. Photographs bring out the amazing and beautiful detail in our galaxy and universe, while sketches can present what is actually visible to the human eye.

This photograph of the winter Milky Way setting over Sunset Crater National Monument is supplemented by 24 sketches that highlight just a few of the captivating deep sky objects that reside in this richly adorned stretch of our galaxy. I originally set this up to work as a rollover graphic (with & without callout lines). The second image below leaves the callout lines out.

Kind regards,

hello
this is my first post so apologies if this is the wrong thread or forum.

above is an image of the propeller nebula (aka DWB 111, Simeis 57), part of an extended HII region in cygnus. as far as i can tell the phenomena causing this unusual nebula are not well understood. it doesn't look like a typical emission nebula with a bright star(s) causing emission from the surrounding gas, nor does it look like a random shockwave in space.

can anyone help explain this nebula?

imaging details:
FS 102 @ f/6 (2.14"/px); Astrodon 5nm Ha, IDAS LPR filters, SX H9/H9c
Ha 57 x 10 min, RGB 52 x 5 min, 7/22-23,8/8-9 2010, los alamitos, ca
(reduced to approximately 3.5 "/px).

Nice image of the Omega Nebula, Wolfgang!

I checked out your homepage, and I love this image of yours of the Lagoon Nebula:

[url]http://www.astro-pics.com/m8plm.htm[/url]

The image is most definitely color enhanced, but that just makes it more beautiful, according to me! :mrgreen: Also, the enhanced color brings out some real but subtle color differences across the fact of the Lagoon. For example, I had previously noted blue reflection nebulosity in exactly those places where it is so prominent in your picture. Also, I had noted that the Lagoon is at its most pinkish-red at exactly the places where your image brings out that color, in a sort of "ring" or "wreath" around the bright cluster and star forming center of the Lagoon. I had also noted the color difference between the magenta hue of the main Lagoon Nebula and the brick-red large patch to the left. Also note the many intensely red "streamers" to the north and west (right) of the main nebula.

That sure is a delightful image!

Ann

I'm in awe of the quality and variety of submissions to APOD!!! I have to admit to a wee bit of jealousy of all of your photographic skills.

As for Earth-bound photos, I was totally unaware that Italy had such vast open spaces - I also especially liked the last picture with the old barn in the foreground!!!!

Taken on Oct 2nd 2010 in New Jersey at Cape May Point. Was not expecting anything other then the typical sunset and was pleasantly surprise to see the "Etruscan" sunset unfold. I choose this image as the "best" but did record the entire event. My hope was to see a green flash but it never appeared.

Using the [url=http://asterisk.apod.com/viewtopic.php?f=29&t=21191][size=110][b]<- Previous submissions[/b][/size][/url] link in the first post makes it possible to page back through earlier submissions threads; each submissions thread has a link to the previous submissions thread in the first post. A lot of fabulous images are submitted to APOD; I don't know how the editors manage to select just one per day!

:rocketship: Thank you for sharing your wonderful camera views of the universe and Mother Earth with all of us homebound folks. What a pleasure it is to look at these images. Did you see the physist Dr. Michiro Kaku's 3 hour interview on tv last evening (Oct. 3, 2010)? What a fascinating life we have happening all around us.

[quote="Ann"]Those are three lovely images, David Kaplan. I like them all, but my favorite is the last one. I love the poignancy of the little human-made shed seen against the towering mountains, the products of mighty geological processes on Earth, and the vastness of the cosmos out there. The tiny white cloud adds a touch of the ephemeral.

I love the intensely blue color of the sky, by the way (but that's me, I like everything that is blue). Tell me, why is the sky so bright behind the mountains in all three images?

Hi Ann

Thank you for your feedback. I think the bright part behind the mountains comes by one part from the strong vignetting of the lens (light falloff at the edges) and by another part from the rising moon which wasn't visible but I know it was rising :).

Hi folks

Following three pictures where taken during the last week in the Dolomite Alps in Italy.

Thanks Ann and hello all.

What a lovely image, Jaime Fernandez. The colors are absolutely splendid!

And welcome to Starship Asterisk*!

[quote]BTW, the image looks much nicer when it is viewed at about double this scale.[/quote]
Agreed! I had a lot of fun on your website looking at the image and its various incarnations!

[quote="bystander"]I'm curious as to what the glow is at the bottom of the "globe".[/quote]
I believe these are due to light pollution from the nearby town Narrabri (about 25 km / 15 miles away) and a refinery that is a bit closer in. Initially when I took the photos I was a bit disappointed by this (the astronomer in me was creeping in) but when I looked at the final stitched image I found it actually added to the mystique of the image (it reminded me of a total solar eclipse).

[quote="owlice"]Looking at the image in its small size on the thread, the telescopes look like large trees to me (even with my glasses on :shock: )[/quote]
Yes the "planetary" features are a bit on the small side - I was more trying to highlight the beauty of the Universe surrounding it :D BTW, the image looks much nicer when it is viewed at about double this scale. BTW, thanks for the warm welcome. :D

Cheers,

Emil.
