The sky is dark with just a sliver of a moon setting in the evening and our smokey skies fairly clear for a short time, so I set up to image and found the Dumbell Nebula a solid target for a little over 2 hours of 360 second frames. Each time revisiting  a target like this is a small step forward in my experience and of course some great time under the night sky. On this occasion I had a pair of new 10×50 binoculars to scout the heavens and our human creations streaming by. Reminders of the eternal and the transient reality.

 

Dumbell Nebula

The Lagoon Nebula is a giant interstellar cloud in the constellation Sagittarius is classified as an emission nebula. Discovered by Giovanni Hodierna before 1654 it is one of only two star-forming nebulae faintly visible to the eye from mid-northern latitudes. This is rather low in the southern sky for me and not the best part of the sky to collect images most nights. I took a chance at getting enough clean frames and I am so impressed at the result! 

One hour 25 minutes of 300 second frames at ISO800. Warm temperatures but near new moon and rather clear air for this time of year. Very little smoke or moisture interfering with the horizon.

From August 10th I captured 30 good frames at 240 seconds each to get this image of M92. With an apparent magnitude of 6.3 it is one of the brightest globular clusters visible from the Northern Hemisphere at a distance of 26,700 light years away.

“Messier 92 is a globular cluster of stars in the northern constellation of Hercules. It was discovered by Johann Elert Bode in 1777”

“Characteristic of other globulars, Messier 92 has a very low abundance of elements other than hydrogen and helium; what astronomers term its metallicity. Relative to the Sun, the abundance of iron in the cluster is given by [Fe/H] = –2.32 dex, which equates to only 0.5% of the solar abundance. This puts the estimated age range for the cluster at 11 ± 1.5 billion years.”

Next is a crop of the lower right edge where several galaxies but in.

Last year around this time I first captured this area centered between the Deer Lick Group on the left and the Stephan’s Quintet on the right. I came back to this location on a warm evening waiting for the first quarter moon to set and was able to stack 2 hours and 42 minutes of 360 second subs. The dominate galaxy is 40 to 50 million light years distant while the lesser  ones are perhaps ten times as far away.

This was an attempt to get some detail from a region between the prominent East Veil and West Veil filaments. I did not get a lot of results despite compiling over two hours of 300 second frames. The star field was unexpectedly dense and bright making the post processing push heavy handed to get these results. Near new moon and very warm still night were in my favor though.

Veil Nebula

I did this run last month and was not happy with the stacked image. I could not see obvious nebulosity so I knew it would need to be pushed a lot. Kinda made me want a new camera as in one that could pick up the Ha and less noise. This is designated as NGC6823 and it CAN have some cool detail but this image is not much to talk about. Here for history is 21 frames at 300 seconds for 1 hour 45 minutes of dense stars and faint nebula.

NGC6823

Last night was a great night under the stars. Warm summer air is not the best temperature for my stock DSLR imaging, but the air was clear, dry and stable with no moonlight. The North America Nebula was well positioned for a good run and the dark sky would help with my unfiltered equipment. I ran 240 second exposures with good tracking for a total integrated time of 2 hours and 16 minutes using only dithering for noise management. I was also keeping an eye on comet Neowise which was not as bright as I had hoped for but nice views with binoculars and our Orion 130ST telescope.

A nice small group of galaxies each showing a very different type from April 20th.

I found these on Stellarium and know them just by the catalog numbers but I really like this group. A small scale target for my setup but a fine subject for a return visit when I have better gear perhaps.

       I had several dark nights with the telescope last month but only just got around to updating my astrophotography blog site. After submitting the image to the online service http://nova.astrometry.net/ I identified them as NGC5981, NGC5982 and NGC5985 top to bottom also known as the Draco Trio as they are located in the belly of the dragon constellation. The close grouping of an edge on, an elliptical and a spiral galaxy makes a nice portrait.

 

From April 17th.
The Splinter Galaxy. Conditions were about as good as it gets and this faint object (Magnitude: 11.1) is shown as the result of nearly three hours of exposures each six minutes long. Note the two adorable little galaxies in the lower right corner. Little of course is somewhat relative. For all I know they might be bigger than our galaxy!
I watched dozens of Starlink satellites (at least I THINK they were satellites) march in formation across the sky and by some chance they missed running over my target. Not too happy to think these will be the new normal in the early night sky.
From the internets: “NGC 5907 is a spiral galaxy located approximately 50 million light years from Earth. It has an anomalously low metallicity and few detectable giant stars, being apparently composed almost entirely of dwarf stars. It is a member of the NGC 5866 Group.”

From April 16th. The Covid-19 sort of took over life there for a while so just now getting caught up on some recent images.
The “Blowdryer Galaxy” also known as M100 was captured two nights ago as the main attraction but a dozen other galaxies can be found without much trouble in the larger frame which is essentially the full usable frame of my current setup.
Borrowed from Jim Gardepe is the following description:
“The galaxy Messier 100, a.k.a. the “Blowdryer Galaxy” (who thinks up these names?) is one of the largest and brightest members of the Virgo Cluster of galaxies. It is located in the constellation Coma Berenices. Messier 100 is an example of a “grand design” intermediate spiral galaxy. It is approximately 55 million light-years] distant from Earth and has a diameter of 107,000 light years.
Messier 100 is considered a starburst galaxy, with the strongest star formation activity concentrated in its center – where intense star formation has been underway for about 500 million years.”
