This is such a fascinating picture!

It is almost impossible not to compare the size and color of M101 (at upper left) and M51 (below center right) in this picture. M51 looks a lot smaller than M101, even with the "help" of its satellite galaxy, NGC 5195. The apparently small size of M51 might be an illusion, of course, if M51 is much farther away than M101, but according to Wikipedia (here and here), their distances are relatively comparable. So M101 really is considerably bigger than M51, and it doesn't just look that way.

It is also obvious that M101 is a lot bluer than M51, or, to be more precise, there are many more hot bright stars in M101 than in M51.

As a lover of blue stars, I can't help noticing nearby Milky Way B3V-type star Alkaid, end star of the handle of the Big Dipper, shining bright in the middle of the picture! :D And Mizar and Alcor, the famous "double star" of the Big Dipper, are at top right in the image.

Messier 49 in Virgo

Copyright: Mark Hanson
M49Aopdsmall.jpg
"M49 is a large elliptical galaxy with a tenuous diffuse tidal shell structure. With a magnitude of 9, it is easily observable by visual observers. It is located 56 million light years away and forms a magnificent if unappreciated galaxy group.

One of the many members of the Virgo Cluster, M49 is a giant elliptical galaxy with a size of 157,000 light years. It is home to an estimated 6000 globular clusters, which seem to be found in greater abundance in elliptical galaxies.

M49 is interacting with the blue dwarf galaxy UGC 7636 below and to the left of it. This is visually illustrated by a diffuse tidal plume to the north of it stretching towards the direction of M49. The tidal plume has a size of approximately 100,000 x 20,000 light years. M49 was also included by the late Halton Arp in his Arp Atlas of Peculiar Galaxies as Arp 134."

This is a great image! It is sharp and detailed and beautifully colored, and I had tons of fun comparing your picture with the information I could find on my software.

The galaxy that fascinated me the most is the small blue satellite galaxy interacting with M49, UGC 7636. My goodness me, this small faint galaxy contains a number of really bright clusters! I mean really bright! Compared with the brilliant clusters of UGC 7636, the globulars of M49 are downright hard to find. I'd really love to know more about this small blue galaxy sporting so many brilliant clusters!

Another truly, truly fascinating galaxy in your picture is NGC 4492, the very round galaxy below the striking barred spiral at upper left. NGC 4492 has a nondescript old to intermediate beige disk, then a fascinating blue stellar ring bordered by a very obvious dark dust ring, and then a sunflower-yellow inner bulge, with fine dust lanes winding their way far into the bulge. I love ring galaxies, so this one was a delightful find for me. Tell me though, is that pink splash in the yellow bulge of NGC 4492 really an emission nebula, or is it a photographic effect?

In any case, you have produced a really great and highly resolved picture of a rarely photographed group of galaxies in Virgo, and I thank you very much for that! :D

Ann,

Thanks, I'm not really sure about the NGC 4492, I spend some time to make sure i didn't blow out this galaxy. I worked hard on keeping it true and bringing out the detail. Here is a closer view.

The Milky Way rising behind the seeing monitor at Paranal Observatory. This monitor measures how the atmospheric turbulence blurs the shape of the stars (the so called “seeing”), and it’s an essential tool in Paranal to schedule observations. Some observations are very demanding and require very stable atmospheric conditions, whereas others can be done with bad seeing. This monitor gives us the seeing every several seconds; that way we can decide on the fly which observations have higher priority, thus making an efficient use of the observing time. Canon 6D + Rokinon 24 mm at f/2, 20 sec, ISO 3200.

Objects: IC4592 and IC4601

Description: IC4592 aka the Blue Horsehead Nebula is a brilliant and large reflection Nebula in Scorpius. It is a cloud of interstellar dust lit by the septuple star system we call Jabbah (or Nu Scorpii) that makes up the eye of the Horsehead. I captured this image at the Delmarva Stargaze star party with my new Stellarvue SVQ86 and an unmodified Canon 5D DSLR.
Resolution: 5621x3567
Integration: 2.0 hours (24x 5 minutes)

New Moon lunar crescent

Post by Thierry Legault » Tue May 15, 2018 1:45 pm

The very thin lunar crescent at the precise moment of the New Moon, today May 15 from Normandy at 11h48m UTC!
nm_180515[1].jpg
http://www.astrophoto.fr/nm_180515.jpg

The separation from the Sun being only 5°, the sky was extremely bright and I had to:
- use an infrared filter to decrease the blue of the sky
- combine the 4800 video frames taken during 1 minute
- place in front of the telescope a maks protecting it from the direct sunlight
- aim the telescope to the Moon with an automatic pointing system (GOTO)
