Hope you like it, clear skies!

Felix, that's a great mosaic of the Heart Nebula with superb detail.

Hope you don't mind that I see a dog in it!

Pictured here is the beautiful Messier 61 galaxy that lies approximately 55 milion light years from Earth. I captured only 3.5 hours worth of images on the galaxy using a PlaneWave Instruments CDK600 from Observatory El Sauce (ObsTech) in Chile. Astronomers recently discovered a bright new shining star within this galaxy, which imploded upon itself in a massive fashion called a supernova.

Sombrero Galaxy (Deep). KG Observatory, Julian, CA.

During this time of the year we see very dark skies due to a marine layer at lower altitude. That along with less lights during quarantine allows us to see 21.7+ SQM skies. (-:

After seeing this deep exposure of the Sombrero Galaxy, I thought I'd try the same with the Planewave CDK24...

https://www.astrobin.com/lduc0b/E/

Now what you see here is tricky. Could some of this be due to my optics? Not sure, but the thick faint stem protruding down with the faint tail off to the right seems like a possible ancient migration?

Processing was minimized to preserve as much as possible with no deconvolution nor gradient removal. Flats were taken very carefully in a completely dark space with an Altinak Flat-Man panel.

Wondering if I should go deeper, especially if this may not be an optical artifact caused by the bright galaxy?

I think that what your image shows is very real.

Good morning from Athens, Greece! In this photo from 19 May 2020, the sun rises through the ancient Greek temple of Godess Athena, the Parthenon, which means "the temple of the virgins". The atmosphere these days is exceptionally hazy due to high concentrations of dust, that originated from the Sahara desert. Thus, the dusty cloud visible on the photo. We experience the strongest heatwave ever recorded in May in Greece and the all time high of the country for the month was broken, as temperature reached 107F (42C).

Thanks Ann for the reference. That's what got me started on this. (-:

I hope to go deeper this week to focus on that faint wide "road" from the galaxy, through those 3 bright stars, and down to the bottom left.

I believe there is a loop at the top as well, but i have not been able to confirm, maybe you can try for that but you will have to alter the FOV.

Wow, Mark, that's absolutely amazingly stunning!!!

The superb detail in the visible disk of M104! The plethora of background galaxies! The wonderful background grand design spiral galaxy near a white foreground star! The beautifully resolved tidal tail, demonstrating that it is made up of stars and not of gas! That humongous faint featureless halo! All of it is totally fantastic!

Thanks Mark! And thanks for pointing out your wonderful rendition. I often use your work for reference.

I'm hoping to get more time on M104 this week while we still have 21.7 skies. I'll try to capture the upper part.

David Malin has the best I could find in that area...

Hello everyone, this is my submission for May 2020.
It's a picture of the sun with data acquired back in 2014 when there was a high solar activity and it's the result of a cooperation between me (Marco Rapino) who I did the processing and Tommaso Martino who did the acquisition.
The equipment used was a Lunt60 B1200 with MagZero and a Barlow lens 2x.
The processing was done using Autostakkert, ImPPG and PixInsight for some final curves and color adjustments.
Video was shot from Italy, Castiglione della Pescaia, Tuscany.
Hope you like it!

Marco

Humans and Nature

Panoramic photo of the Milky Way, which connects two "worlds" - people and nature, where nature is represented by trees and people by the houses in the background. Light pollution at the core of the Milky Way is caused by a very distant city, which, however, still has an impact on the visibility of the sky.

The photo is taken from a dark sky park in Beskydy Mountains in the Czech Republic, which, even when located near large cities, still adheres to quality.

Info: 11 panel panorama, 3 photos stacked to reduce noise (33 photos total)

EXIF: 14 mm | f/2.8 | ISO 6400 | 20" from tripod

Gear: Canon 6D Astro modified + Samyang 14 mm f/2.8

I absolutely love this image of circa 4 billion-year-old open cluster M67 and its many-colored stars. As a lover of all things blue, I am of course delighted to find a true blue B-type star, HIP 43465, a blue straggler, in this cluster (at bottom right). Note that there are a few other relatively blue stars in M67, and note the striking scarcity of blue stars in the field.

M67 rules, and this is a superb photo, Thomas!
