This is cool! Is this in our organic optical window or does the "Tru-Balance 5nm Hydrogen-alpha filter" make it appear different from our human wavelength menu?

Thanks!

Hi Ed,

The H-alpha bandpass is in the red portion of the specturm. Because this nebula has a low surface brightness, detecting it visually can be difficult. From a dark sky site I'm sure one would see evidence of the brighter parts of the core using suitable optics. If I'm not mistaken, NGC 281 was discovered visually by E. E. Barnard in the early 1880's. He was known as an eagle-eyed astronomer with almost super human visual acuity.

Regards,

Dave Jurasevich

http://www.flickr.com/photos/mcastillov ... otostream/ Hello, my name is Manolo Castillo, I send this picture from Chiclana de la Frontera, Cadiz, Spain. It is a montage I made to show a complete picture of the visible face of the moon, but in a particular way.
In the photo we see the waning moon of September 30th the crescent Moon on 15 October. Although the crater Nasireddin appearing in the two phases, and knowing which is located at longitude 0 ° E and latitude 41 ° S, we can not fix the two images to form the full face of the moon. The lunar libration makes us see the moon's surface than the simple projection of sunlight that would give us 180 degrees. As you know, this total would really be a 59%. On the other hand, the terrestrial latitude conditions us to a particular angle of vision. These photographs are made from Chiclana, Spain, 36,417 º latitude.
Hope you like it. Greetings.

NGC6960, the Lacework Nebula

Roughly 1,500 light-years from Earth, the Lacework Nebula resides in the constellation Cygnus and spans 80 light-years. This nebula was created about 10,000 years ago by a rare supernova that occurred in our own galaxy, the Milky Way.

Exposure time: 42 hours
Equipment Used: 16″ RC Optical Systems Telescope, Bisque Paramount ME, STX16803 CCD
Location: Perez Observatory at New Mexico Skies, Mayhill – New Mexico

Here is an image of the Andromeda Galaxy gathering more than 70 hours of exposure time in Narrowband and wideband filters.
To reveal the faint narrowband nebulae a flux subtration was used to remove star flux from the galaxy halo.

In the centre of the galaxy lies a giant H-alpha spiral that has an inclination different from plane of the galaxy itself and was discovered by Dr. George Jacoby in 1985!!
Many types of nebulae can be seen: stellar nurseries, spuernova remnants, and even planetary nebulae are seen (blue dots).

Taken with a 8inch f/3.6 newtonian and a KAF 8300 CCD camera at CROW remote observatory, Portugal.

Hello,
I have decided to send my image of LMC.
This time it is presented in form of regular image and the image with identification of objects which could bee see on it.
My colleague Wojciech Wesolowski decided to identify and describe all star clusters which are visible on the image (it took him 3 weeks to do this exercise).
The RGB image does not contain nebulas which are being currently identified and described in my H-alpha image.
On my image my friend identified and described step by step, based on available deep sky maps, DSS images and other software 817 open and globular clusters together with 6 galaxies marked green.

It is mainly my colleague, an astronomy enthusiast who identified and described objects and for who it is always a great pleasure to do such things.
My help with the job was only a minor one but I am the author of the image
Of course I have managed to gather the data for the image from Southern hemisphere (I live in Europe, Poland) so the picture iseven more important for us.

Descriptions: Wojciech Wesolowski

Sincerely,
Adam Block

There were many great images here!

Ulrik Fristed, it's nice to see an image here from a fellow Scandinavian! And I love your portrait of Vega. No, the blue color of Vega isn't that saturated, but it is, darn it, nevertheless so blue. It knocks you out when you look at it through a telescope. Thank you for this delightful portrait of one of the most beloved stars in the sky!

Filipe, I am the wrong person to impress with pictures rendered in the Hubble palette, but even I like your Andromeda Galaxy. I am particularly impressed with the H alpha spiral at the center of Andromeda.

Bogdan, I am incredibly impressed by the fantastic effort you have undertaken to have all those sky objects in the Large Magellanic Cloud labelled! Wow!!!

And Adam, you know you are my idol for producing all those (260?) color images of galaxies on the NOAO homepage. The Flame Nebula is not my favorite object, mostly because I feel stumped when it comes to having an opinion of the color of it, in the same way as I am stumped by the color of planetary nebulae. Well, your image of the Flame Nebula is beautifully resolved, the color looks very nice, and I suppose the color is accurate!

Ann

I forgot to say that I love the picture of Arp 194! Wow, what an image!!!

And I love the NGC 6914 image, too. This is one of my favorite parts of the sky, with the petite little blue reflection nebulae swimming in that sea of red!
