APOD Submission

Hello,

I would like to submit my photo of the sun's Aphelion to Perihelion for APOD consideration.

Location details:

Aphelion: Oceanside, California
Perihelion: Oceanside, California

Date/Time:

Aphelion: July 5th, 2021
Perihelion: Jan 4th 2022

Equipment:

Telescope: Coronado Solarmax III Double Stack
Mount: iOptron CEM60
Camera: ZWO ASI 174MM


Image acquisition and processing:

I used sharpcap to acquire videos of the sun on both days.

I ran both programs through AutoStakerrt3! and stacked the 100 best frames for each. I loaded each file into ImPPG and processed them to my liking. I then loaded them up into photoshop to blend the two images together.

You have my permission to use this wherever you want.

If selected please link to this:

Thank you for your consideration,

Bryan

IC 410 - Tadpoles.

​IC 410 is a faint and dusty emission nebula of more than 100 light-years across, located near the Flaming Star Nebula (IC 405) in a large star forming (HII) region about 12,000 light-years away from Earth in the northern constellation of Auriga.
The cloud of glowing gas is sculpted by stellar winds and radiation from the embedded open star cluster catalogued as NGC 1893, which is just about 4 million years old.

Target : IC443 - Jellyfish Nebula

Location:
Kuwait - Alhejen Farms - Camel Hangars

Description: 

~ from Wikipedia
IC 443 is a galactic supernova remnant in the constellation Gemini. On the plane of the sky, it is located near the star Eta Geminorum. Its distance is roughly 5,000 light years from Earth. IC 443 may be the remains of a supernova that occurred 3,000 - 30,000 years ago.

this was interesting! the jellyfish is such a huge target with very strong signal in hydrogen alpha so processing the image was difficult. especially as I lost almost one hour of data due to a laptop crash and focus problems. but I knew the data was there and it was clean so I worked hard to get as much information as I could. It was truly a pleasure to work with.

while I wish I had more time on the target I'm moving on to another interesting project and I might revisit the jellyfish sometime next month.

Here is an image of a Dark Nebula Complex showing nice dark nebulosity. I have been unable to find a name for this area, the only known object in the image is a small galaxy IC 3104. This image is from Telescope Live telescopes in Heaven’s Mirror Observatory, Australia. Image is from three sets of LRGB images taken between 28 Dec 2021 and 02 Jan 2022.

The Horns of Venus
The Horns of Venus by Tom Glenn, on Flickr

The "horns" of Venus are evident here as it approaches inferior conjunction with the Sun. This image was captured on January 6, 2022 at 23:44UT, from San Diego, CA. Elongation is just over 5 degrees from the Sun, and the crescent Venus is 0.4% illuminated. The horns (or cusps) extend approximately 270 degrees around the globe of Venus, and exhibit asymmetries in length and brightness. Inferior conjunctions of Venus occur every 584 days and exhibit cycles of 8 years in which each conjunction of a given cycle has similar characteristics. Although this conjunction is limited to about 5 degrees elongation, and therefore a complete 360 degree atmospheric ring is not observed, it is the closest inferior conjunction of Venus until 2028.

Equipment:
6" Newtonian telescope at f/6
ASI183mm camera with 742nm long pass IR filter
The image is pseudo colored (image was captured during daylight), raw data is monochrome, the original grayscale image is posted below:

I really like your image! By the way, the bright blue star near the center of the image is Beta Chameleon, and the double star surrounded by an obvious blue halo to the upper right of it is Epsilon Chameleon.

SwordLESS

In the last night of 2021 from the Maniva Pass (Italy) I took nearly 7 hour of the “sword” of Orion, the nebulae between the Orion belt and M42.
Using a small telescope (Askar FMA180 on a AZ-GTi), a cooled camera (QHY163C) and a L-Enhance filter, this image show only the H-Alpha band of 138 shot (180” @ 90 Gain, guided) combined, with the stars removed by the StarNet process of Pixinsight, data of M42 taken by another session of 60” shot, for the “HDR” result added in Photoshop and, as finishing touch, the incredible ML Noise Reduction of Pixelmator Photo, applied by an iPhone 13 mini!!!

Conjunction of Venus
Copyright: György Soponyai

Today planet Venus passed by above the Northern solar pole so it's completed yet another 17-month-long orbit around our Sun -- as seen from Earth. In fact, the Venus needs only 225 days for a completing an orbit but meanwhile the Earth proceeding on it's orbit as well.
From June to December in 2020 I captured the smaller and smaller crescent and disk of Venus on the morning sky in every ~10 days. The 600 mm focal length of my telephoto lens looked like barely enough for photographing the details of the planet shape, therfore last year I went on taking photos with 1200 mm focal length by using a 2x lens extender.

NGC 2090 in Columba

Copyright: Mark Hanson - Mike Selby
NGC 2090 is an infrequently imaged spiral galaxy located 40 million light years away in Columba. The structure of NGC 2090 is an SC type of spiral, the arms are quite faint and required considerable integration time to properly resolve. NGC 2090 was one of 18 galaxies that were part of the HST Extragalactic Distance Scale Key Project to better define the value of the Hubble constant. The sparse nature of the galaxy’s arms allowed The Hubble Space Telescope to resolve stars leading to a more accurate red shift calculation.

Imaged in LRGB at Observatorio El Sauce, Chile on our CDK 1000 telescope.

Thanks! Checking the stars was a good idea, I forgot to try that.

HDR Moon - Waxing Crescent 21% lit
So I finally made the moon shot I said I would do. It's been awhile I could do the shot since it has been too much clouds and I needed to wait to the right moon phase and time to do this, but here it is!
A moon with a true Earthshine and Moonglow with its true Starfield. Meaning these shots are from the same camera, lens at the same time (120 images used from the Timelapse shot between 18:07 and 18:09 2021-01-06)

Atlas and the Universe

Composite image 06/01/2022

The ancient story of the titan Atlas, who was forced to carry the sky on his shoulders by Zeus at the end of the great battle between Olympians and Titans. In this image, the Andromeda galaxy still visible on the skies of the beginning of the year is presented in a composition reminiscent of that mythological story, a view from the skies of the Tatacoa desert inside Colombia.
