Dark nebulae are a show apart, some visible with the naked eye in places with low light pollution, these regions are a type of interstellar cloud so dense that it obscures the starlight in the background.
Dark clouds appear like this due to micrometric dust particles, coated with carbon monoxide and frozen nitrogen, which effectively blocks the passage of light at visible wavelengths.
THESE DUST MOLECULAR CLOUDS PROBABLY CONTAIN SUFFICIENT RAW MATERIALS TO FORM HUNDREDS OF THOUSANDS OF STARS Here we can see:
1) the serpent nebula in the center (B72),
2) Lower right corner (B261)
3) Three small nebulae from top to bottom on the left side of the healthy snake (B68, B69, B70)
4) In the lower left corner is B74, in the shape of a heart.

Had a lot of fun with this one, its a 60 hour integration spread across a 3-panel mosaic, mostly HαRGB but some Oiii added in for the M42 region (Horsehead had basically no Oiii response even after a whole night of shooting it). 300" and 30" for the narrowband (Luminance), 90" and 10" for the broadband RGB, with the shorter exposures used for detail recovery and star control

Full Moon over the Greater Baghdad area
First time submission.
I apologize ahead of time, I am on a DoD network that blocks everything, so half the buttons on this page aren't loading, and I have no idea what I am doing here, and I can't copy/paste from various menus.
Image was taken from a Forward Operating Base (FOB) outside of Baghdad. Just my Canon Rebel T6, and a 200mm canon lens, single picture. Tripod on top of my building. Yes, I know it looks like a prison, and in many ways it is. Just counting the days till I go home.
Taken 3 April 2020 around 1930.

Little Green Man on the August full Moon?
In this single-shot image, you can see three little humans cheering up at the August Moon as it rises in Horigi Kilkis North Greece. I always wanted to create an image with humans in this beautiful location and the August Moon was the perfect timing to do so. The previous day I visited the location alone and made a few test images to see how everything would turn up for the upcoming full Moon.
I had to bring my two cousins and my wife on-site so they can be in the frame but not all was easy for us there since local wild plants made it very difficult to reach the tip of the natural monument, however not impossible. I had to drive for three kilometres away in order to use my telephoto lens a Nikkor 500mm and a 2X converter in order to achieve a good size on the "aliens" and have some lunar features also shown.
We had to coordinate our shot using our cell phones and after the sun went down, I told the team to use their cell phone flashes in order to be able and spot them and we decided to leave them on during the shot. They do appear as they have a car breakdown and make signals for help!!!
PS. I made this image during the day that my image from Vikos with Neowise was choosen as APOD. What a great way to enjoy that day by making another image with so much fun!!!

Hurricane Isaias: Kiss and Rainbow
After the heart of Hurricane Isaias passed over my observatory 20 miles West of Albany NY, my wife and I kissed in the Sun glow under its rainbow.
It's not very often that we get to see this combination: the moon rising next to the mountain, the setting sun lighting the peak, and perfectly clear sky. Tonight was the night for a hat trick.
Nikon D750, Nikon 24-120 mm at 120, f/11, ISO 100, auto shutter, 12 shots at 3 minute intervals, processed in Lightroom and Sequator.

I would like to submit another one of my cosmic painting depicting NGC 7635, also called the Bubble Nebula - a beautiful object in the constellation Cassiopeia. I created this art based on the object photo made by Hubble Space Telescope.
My technique - acrylic on canvas, dimentions - 50x40 cm.
Painted in southern Poland a few months ago.
Open cluter, globular cluster and comet Comet C/2020F3 (NEOWISE) on 6.08.2020 between the globular cluster M 53 and open cluster NGC 5053

I captured this image of a portion of the famous 'Cygnus Wall' in the typical and classical 'Hubble Palette. I went in tighter than the usual Cygnus wall in order to make the 'boulder' structure stand out more, which looks like colapsing gas.
