About the monument

The eight and a half foot tall bronze statue was sculpted by John Massey Rhind, who created a number of statues at Gettysburg. It stands on a ten foot granite base. An inscribed metal tablet is on the front of the monument above the crescent moon symbol of the Eleventh Corps. The monument was dedicated by the State of New York on June 6, 1922.

Messier 44 (M44), also known as the Beehive Cluster or Praesepe (the Manger), is an open star cluster in the constellation Cancer.

Praesepe is a bright, large cluster with an apparent magnitude of 3.7. It lies at a distance of 577 light years from Earth.

M44 is one of the nearest open clusters to Earth and can easily be seen without binoculars in dark skies. It appears as a blurry patch of light to the naked eye. The cluster is best seen in binoculars and small telescopes.

This is the Andromeda galaxy, this galaxy contains around a trillion stars and it took 2.5 million years for this light to reach my camera sensor. This photo consists of 90 second and 2 minute exposures in bortle 5 (shooting into the highlights of light pollution). It is edited in Photoshop and stacked in Sequator. It was a challenge getting data for this photo because of light pollution, it was low on the horizon therefore I had a minimal amount of time to photograph it (that is why it's noisy). On the plus side it shows the structure of the Andromeda galaxy well and is good considering my level.

Lord, this is a sharp lens! It is one my wife bought years ago for macro photography; I subverted it into a career in astrophotography. The Facebook photo compression algorithm fails us here.

Here we see the central bulge of the Milky Way above the teapot of Sagittarius; Saturn is the brightest "star". An airplane crossed the field in two of the exposures.

I annotated the second image with some of the outstanding features of this exceptionally rich zone.

For those interested in imaging the Milky Way, I tried to apply some of the processing recommendations from an article in the January 2018 issue of "Sky & Telescope" titled "Making Your Nightscapes Pop" by Rogelio Bernal Andreo.

so i got another night of clear sky and captured some more exposure time...

now at 560x15s..

not a dramatic improvement but i think it's getting better... i even managed to retain some detail in the bright central area this time... :)

This is my first attempt at a composite shot. I am happy with the results and was surprised at how far software has come to help build shots like this. The foreground was shot during blue hour. The background is 29 shots stacked in sequator for noise reduction. I also shot two shots with the lens cap on to help the software remove noise.

To the south of Antares, in the tail of the constellation of the Scorpio, at more than 6000 thousand light years is the emission nebula IC 4628 or also known as the Prawn nebula or False comet.

Young stars nearby, massive and hot, radiate the nebula with ultraviolet light, which makes the electrons of atoms jump. When these electrons recombine again, the glow of the nebula is produced, seen here by the red emission of hydrogen.

On the right side is NGC 6231 or better known as the Jeweler of the North (or boreal), this young and massive open cluster is more than 5900 light years, with an estimated age of 3.2 million years, and stands out for its abundance in hot and young supergiant stars much brighter than the sun and that include at least two Wolf-Rayet stars.

Although the purpose of this evening was slightly different, I eventually took even this huge panorama.

Firstly, I needed to test my DIY starglow filter, and when I saw this place with the tree under the Orion, I decided this was the ideal moment.

The starglow filter did a pretty good job! The effect is further enhanced by the cloudiness, which came just when I needed to take the picture. However, I am still happy because this filter enables me to make more realistic pictures.

Secondly, this was the first time I used my new Sigma 28 mm f/1.4, which is amazing with small sharp stars even in the corners!

I was not lucky with the clouds, but on the other hand, I was lucky with the meteors, which doesn't happen to me very often. I saw three meteors, of which two were captured on the camera. Both are on the right of this panorama. The brighter was truly spectacular, it lasted about 4 seconds and was similarly bright as Jupiter.

In addition, I truly like how the sky looks with a modified camera. The red nebulae make the picture more interesting and I really enjoy that.

Thank you @vobaphoto for the company!

I recently returned from a photography trip to Kanab, UT where I met up with a group of photography friends. Thanks to others in the group who have high-clearance 4WD vehicles, we were able to catch a ride out to White Pocket for some night photography. Although the forecast called for clear skies, we watched the sky fill up with clouds as the afternoon progressed. Undeterred, I went out looking for potential compositions to capture the Milky Way arch very early the next morning because my weather apps “promised” clear skies after midnight. I had a blast hiking back and forth over the rock formations – so many different types of lines and textures captured my imagination! I found a couple different compositions that would keep me busy taking photos most of the night, but I knew I would need to take “blue hour” shots for the foreground of a Milky Way arch photo. If I waited until full darkness, I didn’t think there would be enough ambient light to illuminate the foreground and I don’t yet possess the skill necessary to light paint a 180-degree panorama.

As the sun was setting, DH and I followed my GPS track from earlier in the day to return to the spot I wanted to photograph from. I determined that I would need to take 11 photos to cover a little more than 180 degrees (essentially north to south, since that’s where the ends of the Milky Way arch would intersect with the horizon later that night). I started taking photos about halfway through nautical twilight and ended up finishing as astronomical twilight started (about 15 minutes).

As for photos of the Milky Way, I calculated that the Milky Way arch would be perfectly positioned starting around 3:30am according to the PhotoPills app. So we headed back to our tent to try to catch a few hours of sleep. Got up at 2:00am, saw clear skies(!) and followed my GPS track back to the same location. I tried to be cognizant of not shining my headlamp too far ahead of me since there were other photographers out on the rocks taking photos and I didn’t want to mess up their shots. Having said that, it was _really_ dark because there was no moon and I was really glad I had that GPS track to follow because it was difficult to see distant landmarks in the dark. In theory I could have taken the sky photos from the campsite, but I wanted to know for sure that the Milky Way lined up with the landscape the way I thought it would. Even though I took the foreground and sky photos at different times, I wanted the final image to reflect my experience out among the rock formations under the night sky.

As it turned out, there was another group of photographers near the location where I set up who were shining their headlamps all over the place. Luckily, I already had my foreground photos so their “light painting” on the rocks didn’t affect my photos of the sky. I had really hoped to use my new star tracker for this Milky Way pano, but a key piece of equipment didn’t arrive in time, so I went with Plan B which involved taking 6 photos of each of the 11 positions in my panorama (to help reduce noise in post-processing). As a result, my post-processing time for this photo was pretty significant (about 7 hours) because of the various noise reduction techniques I tried (not to mention a couple snags I ran into while trying to stitch the panorama of the sky).

Lessons learned:

•I didn’t realize it at the time, but the color temperature of the light changes A LOT during twilight and even though I took all of my foreground photos during nautical twilight, the color temp shift presented a few challenges for me when I stitched the foreground panorama together.

•My phone did not automatically update to the AZ time zone! It didn't occur to me until the sun was still high in the sky at the time that PhotoPills said it should have set. It turns out PhotoPills was correct, but the system clock on my phone was not. I had to manually change the time zone on my phone so that it matched PhotoPills to ensure that I woke up at the "correct" 2:00am for my Milky Way shots! :-O

Here is a vertical panorama that I made last august.

It has been shot in Cévennes in France. I choose this location because of the granite rocks which are interesting foreground for my photos.

Initially the panorama was smaller but then I had the idea to combine it with another panorama of the Milky Way with the cygnus region that I had done with the same technique and the same equipment (Canon 6D + Sigma 50mm).

So I hesitated a long time to post the initial panorama (smaller but wider) or this one. Here the initial panorama. Which one do you prefer ? Please let me know :)

For Pano 1 (Sky + lower part of milkyway) each tilt is a stack of 6 pictures 30sec ISO-3200 f2.8. For the sky part there are 3 row of 3 tiles and one row with 2 tiles. For the foreground it's a row of 3 tiles that has been shot in the blue hour juste before the night with those settings : ISO-1250 | f5.6 | 1/5sec For

Pano 2 each tile is a stack of between 7 and 10 shots. There are 3 row of 3 tiles.
