Starship Asterisk*

Looks like jellyfish chasing squid
Two objects from Barnard's catalog however there is also part of M24 visible here. I would never guess that Messier's list has something more than clusters, nebulas or distance galaxies...

Hi,

Since I couldn't edit my original post I will add a new entry. Sorry

This image was created with the same data I created the HST version, but this time I only used the Ha and OIII in the following proportion:

Ha = Red, O3 = Green, 0.8*O3 + 0.2*Ha = Blue

Then to add some icing on the cake I replaced the stars with the RGB stars I captured with very short exposures.



A full review of the image (in spanish) can be found here:

Thanks for looking!

Cheers,

Jose Mtanous

Tidal Streams in NGC 770, NGC 772 (Arp 78) - Interacting galaxies in Aries

http://www.irida-observatory.org

Copyright: [url=mailto://info@irida-observatory.org]Velimir Popov, Emil Ivanov[/url]

NGC 772 (also known as a peculiar spiral galaxy Arp 78) is an unbarred giant spiral galaxy approximately 106 million light-years away in the constellation Aries. It is notable for possessing a single elongated outer spiral arm. The asymmetric spiral arms are distorted by interaction with the dwarf elliptical galaxy NGC 770. NGC 770 appears to be at about the same distance as NGC 772, so it is most likely a true companion to the larger spiral system. It has a separation of only 160 000 light-years from its larger companion with an actual diameter of only about 40000 light-years.

... some ideas what can be this nebulosity ?

If you got a deeper image of it you might be able to find some star stream connecting it somewhere to NGC 772... otherwise, who knows. Dwarf galaxy? Local cirrus?

Another 15 hours? May be, one day

To find conections with NGC 772 will be great but I doubt of this. My first assumption was a cirrus also but you are right, who knows.

A (somewhat remote) possibility is that it is a "galactic cirrus" wisp that is associated with the Milky Way rather than with NGC 772. Admittedly this wisp is far from the galactic plane.

Another possibility is that it is associated with NGC 772. If so, it doesn't look much like a dwarf galaxy, because I don't think it has the right shape for it. I note that it appears to be ever so slightly bluer in color and grainier in "texture" than the outer arms of NGC 772.

To me it looks like a wisp of gas, perhaps with a few stars inside it. It has the striated appearance of the reflection nebulosity around the Pleiades, as if it was aligned along magnetic lines.

It is possible that it is a dwarf companion of NGC 772. Look at this image of NGC 4449 and dwarf companion by R Jay GaBany. Could your "wisp of nebulosity" be something similar to this tiny elongated mini-galaxy? Possibly, but let's bear in mind that NGC 4449 is an intrinsically small galaxy, much smaller than the Milky Way, whereas NGC 772 is a large galaxy, considerably larger than the Milky Way. If the wisp of apparent nebulosity that you have photographed is associated with NGC 772, then it must be relatively big, and much, much bigger than the tiny galaxy associated with NGC 4449.

I guess I make invisible posts. Anyway, it's not a good thing to go so far speculating about magnetic fields just because you see some lines.

Thousands of stars forming the milky way galaxy are seen above a deep canyon in Utah. The Colorado River flows 2000 feet below the rim of Dead Horse Point into Canyonlands National Park. The bright light on the horizon is the planet Venus. There is no other object in the night sky brighter than Venus except for the moon, which had set only minutes earlier. The clear weather, dry air, and dark skies make this area one of the best in the country for stargazing.

The two brightest objects in the night sky appear side by side in front of the milky way in a rare alignment. Venus is the blue object, and the yellow object is the moon. Even though the moon was only an 8% crescent, it was brighter than Venus. The band of yellow along the horizon is from the last colors of twilight before it became completely dark. This incredible sky is framed over the Colorado River in Utah. The 2000 foot deep canyon is part of Canyonlands National Park. But this view was actually shot from the edge of a cliff at Dead Horse Point State Park.

Thank you GECKZILA, thank you ANN

Obviously further investigations are needed but now the good visibility (down to 40 degrees altitude) of these objects is in a very short time window: 17:00 to 20:00 UTC. Probably a few more L frames in the next new moon period ...

*From the Northern to the Southern Cross*

This is a 30 image panorama taken from Laguna Cejar in Northern Chile. It is probably one of my most favourite astrophotos I have taken thus far mainly because it harbours many celestial delights.

Firstly we have our own galaxy, the Milky Way stretching all the way from Crux to Cygnus. In the middle of the photograph there is the Moon, the large bright object above the moon in Venus and below the moon if you look carefully there are two other 'stars', Saturn on the right and Mercury on the left.

On the far left we have the large and small Magellanic clouds, our closest galactic neighbours and finally the red hue on the left is airglow, which is an emission from excited OH radicals ~86km high.

Wow, how did you smoothly combine those exposures? Awesome work

I think it is likely to be galactic cirrus nebulosity as there is lots of it in the direction towards Aries. Many galaxies in Aries have great clouds of galactic cirrus around them, most notably NGC 918. There are also lots of high latitude dust clouds catalogued in Aries, most notably LBN 762.

Thank you STARSURFER, you are right. This is obviously a small patch of local cirrus. Today I also checked lots of images and this region is fully contaminated

Hello,

A Meteor shower ,probably a Quadrantids residue ,received using the reflection of the GRAVES radar signal situated in north of France and captured in Turin with a simple omnidirectional antenna and a PCR1500 receiver in CW . We've added a new monitoring station H24, available for everybody here : http://www.sidmonitor.net/gallery/station.html bottom page (refresh if it doesn't appear.) On the live spectrogram are clearly visible many traces of planes and the vertical lines that you see are meteors. Audio of the first image here : http://chirb.it/xfOIPB
