Comet C/2023 A3 (Tsuchinshan–ATLAS) visible in NYC

Comet C/2023 A3 (Tsuchinshan–ATLAS) is making its grand journey through the inner solar system, inspiring astronomers, photographers, and stargazers around the world. As part of this collective fascination, I’m excited to share my photographs I captured of this remarkable celestial visitor against the vibrant cityscape of Brooklyn, NYC.

These photos are my small contribution to the ongoing global observation of this rare comet, offering a glimpse into how even from an urban environment, the wonders of space remain accessible to those with the patience to seek them.

Canon EOS Ra, EF16-35mm f/2.8L II USM Lens, f/3.8, ISO 1600, 2 sec. October 15, 2024.

In a stunning blend of cosmic beauty and urban life, Comet C/2023 A3 (Tsuchinshan–ATLAS) was captured over Brooklyn just after sunset. Although not visible to the naked eye due to the intense light pollution of New York City, the comet revealed itself through the preview on a Canon RA camera.

Nestled between Staten Island and a boat drifting across the water, the comet adds a subtle glow beneath the iconic Verrazano Bridge, demonstrating the magic that can still be found in the night sky, even amid the city’s overwhelming lights.

The next photo dives deeper into the beauty of Comet C/2023 A3, revealing details not visible in the wide-angle city shot. Captured with a Canon EF 200mm f/2.8L II USM telephoto lens, the image showcases the comet’s bright, glowing tail and even a faint anti-tail.

The anti-tail is a fascinating feature that forms due to the unique alignment between the comet, the Sun, and Earth. While the main tail streams away from the Sun, the anti-tail appears to extend in the opposite direction. This is not because the comet has two tails going in different directions, but rather due to an optical illusion caused by our perspective. The anti-tail consists of dust particles along the comet’s orbit, which, under the right angle, seem to point sunward.

These images represent not just the beauty of the comet but also the joy of participating in a global observation effort. Whether observing from a dark, rural landscape or amidst the glowing lights of a bustling city, we all have the opportunity to look up and witness the universe unfolding before us.

Green Sky Utah Airglow Astrophotography Canon 60Da

The sky is green, the night is dark - as simple as possible. This photo was done at Bryce Canyon, Utah. Canon 60Da, EF16-35mm f/2.8L II USM, 30.0 sec; f/3.5; ISO 6400

Green Sky Utah Airglow Astrophotography Canon 60Da

The natural moonless night sky is dark but not black; it is not even blue (no scattering light from sun and moon). Earth atmosphere  emits green, red, orange, yellow light- Airglow!

About 60% of the natural brightness of the night sky at zenith is made up of Airglow. Maximum brightest usually appears at about 10-15 degrees above the horizon, because of the greater the depth of atmosphere at this angle. Airglow is not always uniform. Gravity waves may create considerable variation of Airglow brightness.

You can see Airglow only in real dark sky, but naked eye could not recognize colors. Photos with long exposure able get the colors of Airglow.

The usually dominant color of airglow is green originated from molecular oxygen at 90 to 100 km high. Orange and reddish hue caused by atomic oxygen in 150-300 km above the ground, Yellow light comes from sodium atoms in a layer at about 90 km.

Natural Bridge Virginia Astrophotography

These photos of the Natural Bridge were done during my trip to Virginia. The Virginia Natural Bridge is historical landmark forming a natural arch 215 ft high with a span of 90 ft. These photos were done during the light show called the Drama of Creation. Every day has own colors. Also the show started after sunset so you can see different brightness of the sky.

Puerto Rico Astrophotography

you center your vacation time around the New Moon.

These are photos from my trip to Puerto Rico.

Puerto Rico Astrophotography - Big Dipper constellation, Canon 60Da

 This is the panorama of 4 images. Location - Wyndham Grand Rio Mar Beach Resort, Puerto Rico. Canon EOS 60Da, EF16-35mm f/2.8L II USM lens, ISO -3200, F6.3.

This photo can be used for a question "What is the latitude of the observer?" Palm trees in the image  give the clue to this question.

It is interesting how well known constellations (like Big Dipper) look from different places of the world – Puerto Rico, Yellowstone, Grand Teton.

M42 Orion Nebula using iOptron SkyTracker in NYC

This is my first test of iOptron SkyTracker. Orion Nebula M42 is in the list of top 10 deep sky objects for amateur astronomers. So I choose it for first test. I tried exposer 15 seconds. For fixed tripod with Canon Telephoto Lens EF 200mm f2.8 L II USM it gives star trails. With iOptron SkyTracker even without precise alignment stars looks like points. Weather was good but NYC light pollution, plus it was 3 / 4 Moon near Orion nebula. So I use small ISO (Urban astrophotography). There are results:

Using DeepSkyStacker stacked multiple images. Every Canon Row CR2 image first updated in Canon Row 7 saved as Tiff file and later stacked in DeepSkyStacker. Post processing after that was done in Photoshop.

My dreams happen in reality and I got iOptron SkyTracker! Still using piggy pack of the Celestron 4SE I can track sky by camera at home but it too heavy to get the telescope to the long trip. The SkyTracker is pretty compact and not so heavy and can do the same – follow the rotation of the sky. So fly by air plane to places with dark sky I can get more stars, the Milky Way during one shot, increasing camera exposure.   iOptron SkyTracker pretty much can handle Canon 60Da with Wide Angle EF 16-35mm f/2.8L II USM or Telephoto EF 200mm f/2.8 L II USM lens.

Halloween Astrophotography - Night, New Moon, Street-Lamp and Spider Web

This photo I did in Yellowstone Lake Hotel. Just tested new Lens Canon EF 200mm f/2.8 L II USM for astrophotography. It was new Moon. All street-lamps in the hotel are open and have spider web.  Therefore I got my first Halloween Astrophoto.
