I learned a few new techniques for processing this one, and it si a huge improvement over my original one. It was an advanced request I did back about 6 or so months ago. The before and after (and teh details of the image) are here on my Astrobin: https://www.astrobin.com/24f01u/E/

What an amazingly beautiful image!! :D :clap:

Thank you! I wanted to get it ever since I tried from a state park in Indiana with a badly collimated mak-newt.

Elephant Trunk Closeup (modified SHO)

While I think "E.T.'s Finger" might be a better name we'll go with the traditional label. :)

This is 25 hours and 15 minutes of data captured between 23 and 30 September 2021. All the tech details along with a full size version are available at astrobin: https://www.astrobin.com/zy9yq5/

A Trio of Interacting Galaxies in Pegasus. KG Observatory, Julian, CA

It was mostly cloudy during this October dark cycle. The first 2 nights were clear, dark and steady. During these two evenings I was able to capture over 10 hours of luminance with 2" average FWHM. Little did I know that it would take another 8 days to capture just over an hour of R and B and two hours of green. Overall I'm very happy I could capture at least one object during this unusually overcast month. (-:

"This galaxy system NGC 7769/70/71 is also known as CPG 592 from Karachentsev's catalog of galaxy pairs. This trio of 12-14th-magnitude galaxies lies within the Great Square of Pegasus, about 200 million light-years away. NGC 7771 shows a tidal feature strongly inclined to its disk and aligned with the compact companion NGC 7770, which may represent stars stripped from the smaller galaxy. NGC 7770 shows star-forming clumps in its inner disk, in contrast to the sharp, compact nucleus of NGC 7769."

Sun Analemma observed in Taipei, Taiwan at 4:30PM local time.
If you observe the sun at the same location and at the same time every day, you will find that the sun’s trajectory throughout the year looks like a figure 8 drawn in the sky. This is called sun analemma or directly called the sun figure 8. The figure 8 will be formed, which is related to the elliptical orbit of the earth's revolution and the tilt of its rotation axis. This sun analemma photo of Taipei is composed in Startrails by stacking 30 images taken at 4:30PM on different days with sun filter. They were shot from September 22, 2020 to September 23, 2021 from the same viewing platform on an eastern hill of Taipei.The foreground is the city view of Taipei as seen at the location, with the tallest building being Taipei 101, a famous Taipei landmark.

NGC 3314 from Hubble by William Ostling, on Flickr

A full write-up is on my website here: https://theastroenthusiast.com/ngc-3314-from-hubble/

This object is not one but two – two galaxies seeming to overlap by mere chance. The spiral galaxy in front is viewed nearly face-on, its pinwheel shape defined by young, blue, bright star clusters. Against the glow of the background galaxy, dark swirling lanes of interstellar dust appear to dominate the face-on spiral structure. The dust lanes are surprisingly pervasive, and this remarkable pair of overlapping galaxies is one of a small number of systems in which absorption of light from beyond a galaxy’s own stars can be used to directly explore its distribution of dust.

This beautiful cottage is located near Šumava mountains in Czech Republic. This lovely place keeps its calm and its starry sky which makes this location perfect for astronomers and other friends of clear skies.
Picture was taken in October 2021. This pano was cropped out from full sky pano which was made from 44 single shots with exposure time 13 seconds. Canon EOS 6D camera was used with ISO 6400 and Sigma Art 24 mm lens with aperture 2.2.

Moonset over Teide Volcano Crater

Post by cvdarias » Mon Oct 18, 2021 11:27 am

The almost full Moon sets over the peak crater of Teide, the highest point in Spain and the 3rd highest volcano on Earth from its ocean base. Remember that Teide is an active volcano.

The Shark Nebula (LDN1235) and Anglerfish Nebula (LDN1251) in the Cepheus constellation

LDN1251 (on the top of this image) is a complex nebula containing dark structures and faintly glowing / reflecting dust and gas. This type of object is sometimes referred to as a molecular cloud.

The Shark Nebula (LDN1235), is a dark/reflection nebula located at the bottom of this image.

Total exposure - 27 hours
