Moonset above Megyeri bridge
Copyright: György Soponyai

The lockdown of COVID-19 pandemic let me discover lots of new photo locations in walking distances near my home. For example: I just realized that despite the 13 km distance, I don't need to travel for capturing great shots about Megyeri bridge, the northernmost and youngest one of Budapest.

Monday evening was very cold with heavy turbulent crosswinds that made almost all of my telephotos blurry -- maybe except this one where the 56-hour-old waxing crescent Moon is setting above the bridge.

Our infinite Sun
https://tripswithrosie.com/
Copyright: Rositsa Dimitrova
Explanation: We're almost at the spring equinox, so here's a post dedicated to the Sun. This is the analemma of the Sun - how our own star moves across our sky for the entire year. If you were to take a photograph at the exact same time and position (without moving the tripod) every couple of weeks, this would be the end result. The top part is smaller because the Earth moves slower around the Sun during the aphelion (when the Sun is farthest from us) in the beginning of July. The bottom points represent the Sun during the winter solstice and the perihelion (the closest point of the Sun and Earth) in the beginning of January. Of course, the inclination of the analemma depends on what time of the day you choose to photograph it, as well as where you are on Earth. In this case, the time was 15:30 and the location - Bulgaria (Northern hemisphere). If you are in the Southern hemisphere, however, the top part of it would be broader than the bottom. At the Equator, the solar analemma would be horizontal, and only half of it would be visible from the North and South poles.

The tentacles of the medusa

We are located in the constellation of Gemini, at a distance of about 5,000 light years. Between 3,000 and 30,000 years ago a supernova exploded, generating the rest of the event that we can observe today. It is thought that the core of the star that generated the explosion formed a neutron star, a pulsar. All this makes IC443 a very studied object.

The Fly
HaOIII bi-color

The object commonly known as “The Fly” is a combination of a red emission nebula, blue reflection nebula, and an open star cluster. The star cluster is listed in the New General Catalog (NGC) as NGC 1931, while the nebulosity is included in the Sharpless catalog as Sh2-237. NGC 1931 is located in an extension of the Perseus Arm of the Milky Way about 7000 light-years away. The stars are relatively young at an age of about 10 million years. A study by A.K. Pandey and H.S. Mahra suggest the nebulosity may be a background object to the star cluster (http://articles.adsabs.harvard.edu//ful ... 3.000.html).

The Fly is often imaged in a wide field view with “The Spider” nebula (IC 417) which appears much larger and dominates the field. I have always admired the compact cocoon-like shape of The Fly and chose to highlight its unique features.

THE LEO TRIPLET

Also known as the M66 Group, is a small group of galaxies that are approximately 35 million light years from Earth in the constellation of Leo.
The group is formed by the spiral galaxies M66, M65 and NGC 3628.

Personally, when I added color to the luminance, I was fascinated to see the amount of galaxies that spread like wildfire in the background of the field. It's really exciting ...

This is a HaLRGB image of The Keyhole Nebula, Waterfall Nebula, and many other wonderful objects sitting below the ever-popular Orion Nebula. The data was collected between January to March 2021 during each new moon. The image is roughly 30 hours in total integration, with 15.5 hours Ha from my backyard and the remaining 14.4h LRGB taken from B2 Sonoran Desert skies.

The equipment used was a GSO 6in F5 Newtonian Reflector paired with a ZWO ASI1600mm and Ioptron IEQ30 Mount. Filters used were ZWO LRGB and Astronomik 6nm Ha. Processed in PixInsight. Hope you enjoy the shot!

NGC 2237 the Rosette Nebula by Cory Arnold.




by Cory_Arnold on Telescopius

The Rosette Nebula is an H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The open cluster NGC 2244 is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula's matter. I've only been at this hobby for 8 months now, so if you're just starting out there's hope for everyone!

Santa Maria Jump - Iguazu Falls - Brazil

In this image we have the Milky Way Core hovering over the Santa Maria jump, which is one of the main waterfalls in the Iguaçu Falls complex. In addition, we can identify the glowing planets Saturn and Jupiter just above the waterfall and the zodiacal light illuminating the sky and giving more prominence to this incredible landscape.
In order to capture this image, it was necessary to ask permission from the Iguaçu National Park administration to move at night in the park area, which is a risky task, since we have the presence of jaguars and pumas at the site.
In addition, the waterfalls generate a water spray so strong that we stop being in the shower when capturing images. Capturing this image took a lot of work, determination, courage and persistence.
