Lunar Transit through Earth's Umbra

I wanted to share the telephoto shots of the partial eclipse moon taken on Sep 17, 2024 from Jersey City, NJ, USA. This is a composite of 9 images.

Image Image

Image

Consider this image shot from space and you fixed the Umbra and Penumbral region in space (I know that’s not what happens) but just for the simplicity. You then see the full moon transiting from lower right to upper left through Earth’s shadow. This composite of 9 images shows end-to-end partial phases with the greatest partial eclipse in the middle. Keyframes taken are 10:12,10:20,10:28,10:36,10:44,10:52,10:59,11:07,11:15. All times in PM EDT of Sep 17, 2024.

How did I orient this? I referred to Mr. Eclipse Fred Espanak’s geometry diagram (https://eclipsewise.com/lunar/LEorth/20 ... Sep18P.gif) in Sep 17/18 Eclipse Page (https://eclipsewise.com/lunar/LEprime/2 ... prime.html) and oriented my lunar discs exactly like his diagram. Referred to the relative size of the Umbra and Penumbral compared to the moon in this diagram and other sources and its 2.7 and 4.8 times the moon’s diameter when the moon was 353,596 km away from the Earth on Sep 17, 2024.

I've attached 3 images (Non-Annotated & 2 Annotated)

Non-Annotated (1st Image): Shows the passage of the moon through Earth’s Umbra from bottom right to top left. It doesn’t show the Penumbral eclipse moon disc but just the partial phase.

Annotated (2nd Image): Have outlined the truncated view of Umbra and Penumbra of Earth’s Shadow with necessary annotations.

Annotated (3rd Image): Have outlined the full view of Umbra and Penumbra of Earth’s Shadow with necessary annotations.

Greatest/Maximum Partial Eclipse Harvest Moon

I wanted to share the telephoto shot of the partial eclipse full harvest moon at the time of greatest or maximum eclipse that happened at 10:44 pm EDT (New York Time)

Image

Single exposure shot of the Full Harvest moon at the maximum eclipse. Taken on the night of Sep 17, 2024 @ 10:44 pm EDT. EXIF: ISO 800, F8.0, 1/200s. The loss of details in the craters is because the clouds made it difficult to image. Lots of wispy high clouds reduced the seeing considerably. The halo around the moon is a testament to that.

Telephoto End-to-End Partial Lunar Eclipse Key Phases Composite

I wanted to share the telephoto shots of the partial eclipse moon taken on Sep 17, 2024, from Jersey City, NJ, USA. This is a composite of 8 lunar disc images.

Image Image

I've attached 2 images (Non-Annotated & Annotated)

Non- Annotated: (1st Image)
The Telephoto images of the moon were captured @ 400 mm FL on iOptron Sky Guider Pro Tracker. The first disc is the full harvest moon at the time of the full moon rise. Rest all are captured 2 hours later starting from the Penumbral Eclipse phase. Key times of the eclipse obtained from timeanddate.com eclipse page for New York: https://www.timeanddate.com/eclipse/in/ ... o=20240918. Orientations are adjusted as observed from Earth with the aid of simulation in Stellarium. My iOptron tracker set my camera in a weird angle during the eclipse and I had to course-correct it every time. So felt it's better to verify the actual moon orientation at different times using Stellarium.

Annotated: (2nd Image)
The lunar disc assembly of 8 images and annotations was done in Adobe Photoshop 2024. All times mentioned are in Eastern Daylight Time (New York Time).

Tech Specs:

Camera:
Body: Canon EOS-R Mirrorless

Wide Angle End-to-End Partial Lunar Eclipse Trajectory Composite

I wanted to share the wide-angle shots of the partial lunar eclipse moon taken on Sep 17, 2024, from Jersey City, NJ, USA. This is a composite of many lunar discs imaged as a timelapse and later merged to show the actual trajectory of the rising full moon from Jersey City, NJ, USA.

Image Image

I've attached 2 images (Non-Annotated & Annotated)

Non- Annotated: (1st Image)
This is a cropped composite of lunar images shot at 31 mm FL and each disk is spaced 2.5 minutes apart. I took images of the moon every 30 seconds on an intervalometer. A composite of the lunar discs from 9:52 pm to 12:14 am EDT shows the progression of the eclipse from the Penumbral to the Partial to Penumbral phase. Heavy passage of clouds messed up the exposures of many lunar discs, I tried my best to normalize them. Also, a thick passage of cloud after the partial eclipse resulted in missed transit of the penumbral eclipsed moon (top right in this pic). The lunar discs are spaced 2.5 minutes apart.

The background of the partially clear sky was added from a foreground shot I took at 9:21 pm EDT.

All the lunar and partially clear sky images were imported into Adobe Photoshop 2024 and stacked in Lighten mode.

Annotated: (2nd Image)
I've marked key lunar eclipse phases and the times in Eastern Daylight Time (New York Time).

Wide Angle End-to-End Partial Eclipse Composite with Freedom Tower

I wanted to share the wide-angle composite shots of the end-to-end partial eclipse phases of the full moon rising over the Freedom Tower, New York, taken on Sep 17, 2024, from Jersey City, NJ, USA. This is a composite of many lunar discs spaced 2.5 minutes apart.

Image Image

I've attached 2 images (Non-Annotated & Annotated)

Non-Annotated: (1st Image)
This is a wide-angle composite showing various phases of the partial lunar eclipse with the Freedom Tower in the foreground. The moon at the maximum eclipse was 37 deg high making it impossible to capture it close to any known points of interest. After due thought, I felt imaging with Freedom Tower would be ideal as I live close to it across the river and it still looks pretty tall! The lunar discs are separated 2.5 minutes apart.

Given how tall the moon is with respect to the ground and how wide I had to shoot
(31mm on full frame camera), I couldn't fill the entire width of the frame with the lunar disc, I just took a part of the lunar trajectory. Thus, I cropped the image to 9:16 which augurs well for Smart Phone lock screen too but more importantly helps show just the key frames without making the moon trajectory dangle in the air.

The foreground shot was taken after the moon exited my camera’s field of view around 12:28 AM EDT. But, at that time it was very overcast and thus you see clouds in the frame. I couldn’t take a shot of the Tower with a partly cloudy sky during the eclipse as the moon was already in the frame, so it’d looked very odd to see a bright blob in a long exposure foreground shot.

The images were taken every 30 seconds on an intervalometer. I chose the keyframes based on the times provided here: https://www.timeanddate.com/eclipse/in/ ... o=20240918

All the lunar and partially clear sky images were imported into Adobe Photoshop 2024 and stacked in Lighten mode.

Annotated: (2nd Image)
I like to annotate eclipse images (both solar/Lunar) to make it more informative. I went ahead and marked the key phases and the timestamp on the image.

Full Harvest Moon Rise over Manhattan, New York

I wanted to share the Single-Exposure telephoto shot of the full harvest moon rising over the Manhattan skyline, around 3 hours before the start of the partial eclipse on Sep 17, 2024, from Jersey City, NJ, USA.

Image

The yellowish-orange moon rising over Manhattan landscape across the Hudson River from Jersey City looked very surreal. Surprisingly, it was very overcast above but the moon rising through the haze, eventually brightened up. A single exposure shot was taken at 7:15 PM EDT, and just 3 hours before the moon entered Earth’s Umbra.

Ic434

IC 434 is an emission nebula visible in the constellation of Orion; thanks to its presence it is possible to observe the famous Horsehead Nebula, a dark cloud that overlaps it on our line of sight.
This is an H II region that extends south of Alnitak, on the southwestern edge of the large Orion B cloud; it has a very elongated shape in a north-south direction and receives the ionizing wind directly from the star σ Orionis, a bright member of the large Orion OB1 association.
The nebula reaches 70' in length and is easily shown in long exposure photos or CCD images, although its thickness is only a few arc minutes.

The temperature of the region was measured using various methodologies and exploiting various radiation ratios, initially obtaining values ​​between 8000 K and 7600 K;
subsequently this value was reduced to 3360 K and even less depending on the map taken as reference. A study on electronic temperature conducted in 1992 instead provided a value more similar to the previous ones, which is around 6000 K.

M31 Galaxy

The Andromeda Galaxy (sometimes also known by the old name Great Andromeda Nebula or by the catalog acronyms M 31 and NGC 224) is a large barred spiral galaxy located about 2.538 million light-years from Earth in the direction of the constellation Andromeda, from which it takes its name. This is the large galaxy closest to ours, the Milky Way; it is also visible to the naked eye and is among the most distant objects visible without the aid of instruments.
The Andromeda Galaxy is the largest of the Local Group, a group of galaxies which also includes the Milky Way and the Triangulum Galaxy, plus about fifty other minor galaxies, many of which are satellites of the main ones. According to studies published in the 2000s, derived from observations of the Spitzer space telescope, it contains approximately one billion stars (one thousand billion), a number higher than that of the Milky Way, estimated between 200 and 400 billion stars. However, there are conflicting opinions on the mass: some studies indicate a mass value for the Milky Way equal to 80% of that of Andromeda, while, according to others, the two galaxies would have similar mass dimensions. However, some studies suggest that the Milky Way contains more dark matter and could therefore be the one with the greatest mass. With an apparent magnitude of 3.4; the Andromeda Galaxy is one of the brightest objects in Messier's catalogue.

High resolution there for cropping as desired, and a starless version with galaxies for a possible fun overlay.

I love Abell 39. Just sort of a bizarrely symmetrical bubble floating around in space. I’ve wanted to photograph it since the first time I stumbled across someone’s image. And when I noticed how many lovely little fuzzies there are in the star field, and the faint dust in the region, the project only grew. Quite happy with how this photograph of one of my favorite deep space oddities turned out. :)

I hiked up a mountain top, Skeirfe in Sarek National Park, northern Sweden, hoping i would be able to capture the famous Rapa Valley under the aurora.

There are not many chances every year where you able to get this combination. Most of the year it will be covered in snow, or it is midnight sun and it is impossible to see the aurora. Or it is cloudy, as this is the wetest area in Sweden. The aurora also needs to be strong enough to be visible over the southern horizon.

After two days of hiking I reached the top. The sky was nearly perfectly cloud free and and hardly a single gust of wind on the top and only a couple of degrees below freezing during the night.

As soon as it started getting dark the aurora appeared and danced all over the sky. Got plenty of pictures before it subsided and seemed die out. I got in to my sleeping bag and dozed off under the stars. At 3 am I woke up from it starting get bright, so I opened my eyes and saw the aurora building up again. So I grabbed the camera and got it set up just in time to get this shot when the sky exploded again, and perfectly aligned over the river delta! I couldn't have asked for better circumstances. 😃

IC 5146, (also known as C 19), is an open cluster linked to a diffuse nebula visible in the constellation Cygnus.
It is located 3.5 degrees east of M39, in the northern part of the constellation; it is invisible with binoculars, a 150mm telescope is needed to appreciate the object at all. It is a small cluster surrounded by a very compact nebula (cocoon-shaped), connected in turn to a system of dark nebulae, known by the acronym B 168, which extends for about 2 degrees in the direction of M39, very evident even with small instruments as it obscures a rich star field. The main star of the cluster has magnitude 9.74 (but it probably only appears as an "overlay" for perspective reasons, because its distance would be less than that of the cluster). This set of nebulae would have a distance from the Sun of about 3300 light-years.

Comet C/2023 A3 (Tsuchinshan-ATLAS) is only a few days from perihelion, and brightening rapidly. This image was taken just a few hours ago (at the time of posting), showing the beautiful comet and its tail at dawn, rising over the alpine Lake Pukaki in New Zealand.
If the comet survives its journey around the Sun, it could put on an amazing show throughout October.

The Dumbbell Nebula (also known as the Dumbbell Nebula, from its corresponding English name) or with the catalogue acronyms M 27 and NGC 6853) is a famous and bright planetary nebula visible in the constellation of Vulpecula.

The nebula is about 1360 light-years from Earth, has an apparent magnitude of 7.4, has an apparent diameter of about 8 arcminutes and an estimated age of 9800 years; its shape resembles that of a prolate spheroid and is seen along the perspective line of the equatorial plane. In 1992 it was determined that the expansion rate on the plane of the sky of this nebula is not more than 2.3' per century: consequently, a maximum age limit of around 14,600 years can be determined. In 1970, the real expansion velocity was calculated, equal to 31 km/s. Since the major axis has a radius of 1.01 light-years, the kinematic age of the nebula would be 9800 years.

Black Sand Beach (Reynisfjara/Vík)
Location: Reynisfjara beach near Vík í Mýrdal, Southern Iceland, is famous for its striking black volcanic sand and dramatic basalt sea stacks (Reynisdrangar) rising from the ocean.
Coordinates: 63.403° N, 19.045° W
Terrain: Volcanic black sand beach with towering sea stacks, a unique backdrop for astrophotography, especially with clear skies.
Mars & Jupiter near Orion (September 10, 2024)
Mars: On September 10, 2024, Mars will be located in the constellation Gemini, near Orion’s right side. It will be visible in the evening sky, about 20° above the horizon, making it a prominent feature for your shot.
Jupiter: At this time, Jupiter will be in Taurus, positioned near Aldebaran (the eye of the bull). Jupiter will be brighter than Mars and slightly to the left of Orion, with an apparent magnitude of around -2.6, making it easily visible in dark skies above the beach.
Orion Rising: By early September, Orion will begin to rise in the eastern sky in the pre-dawn hours, with its characteristic three-star belt and red supergiant Betelgeuse. On this night, it will rise around midnight from the east, positioning itself above the iconic rock formations of Vík’s black sand beach.
Astrophotography Data:
Captured with Canon EOS RA,Askar h alpha filter, Sigma art 28 mm lens 3 pannel panorma RGBHA
Time for best capture: Around 3 am to early morning, Capture the rising Orion, Mars, and Jupiter.
H-alpha signal: Orion contains several H-alpha-emitting nebulae, such as the Orion Nebula (M42) and the Horsehead Nebula, making it ideal for capturing red emission highlights

Total Integrated Exposure: 24 hrs 30 mins
IC1396_SHO_AstroDarks_Apod.jpg
This nebula, located about 2,400 light years away in the constellation Cepheus, features a striking pillar of gas and dust, shaped by intense UV radiation from nearby massive stars. The Garnet star or Mu Cephei or Erakis (seen far right) is a red hypergiant more than 100,000 times brighter than Sun. It is also one of the largest known stars with a radius around or over 1,000 times that of the sun, and were it placed in the Sun's position it would engulf the orbit of Mars and Jupiter.

ImageLast Night in Summer by Wael Omar, on Flickr

Before Autumn equinox by few days I took a vacation from work and drive for 5 hours away from Home to reach a dark sky location. I intended to have a last look at the Milkyway heart before it goes down the horizon and never appears until the next summer.
I deployed my equipment and astrophotography gears and while doing so I noticed that the heart of the Milkyway which is so bright in the sky was just behind me , it was so wonderful view and I thought to have my pose imaged while I staring at the milkyway and so come the idea of this image.

Gears:

Sony A7III astromodified Ha

Sigma 24-70 mm F2.8

Settings:

· Sky: Stacked of 90 subs iso 1600, 60 seconds , F2.8

· Foreground: one single image iso 1600, 30 seconds , F2.8.

I have to stand steady without any movement while imaging to avoid blurring myself in the image and it was windy so I had to repeat shooting several times until I succeeded in one of them.

All images are from same place same gears same night.

New photo of comet C/2023 A3! Captured in the early hours of 09/26, it reveals impressive details of the comet's tail. The atmospheric conditions were perfect, with clear skies from start to finish during the observations.

For the first time, I saw a comet's tail with the naked eye. It was incredibly rewarding, marking a historic moment to be etched in my memory.
