🔭📷 #Astrophotography summer object: The Cygnus Wall (NGC 7000).

I'm really amazed about the mix of dust and gas emission clouds.

Total integration time of 10.5 hours during 2 nights using the SHO palette.

After over a month of cloudy nights, the sky finally opened up last Sunday night. I took this opportunity to get out and try a new filter I ordered in March and received early July - Astrophotography is definitely exercising my patience.

These are the North America and Pelican nebulae (NGC 7000 & IC 5070) in the Cygnus constellation. The image uses the HOO palette where the Hydrogen emission line (Ha) is mapped to the red channel of the image and the Oxygen emission line (Oiii) is mapped to the green and blue channels.

The dark nebula LDN 935 is a gigantic interstellar dust cloud that separates the two emission nebulae by blocking the light they emit, giving this dark appearance.

It's been a dreadful Spring and early Summer here in #Newfoundland for astronomy. But finally some clear night skies last week or so. Fortunate to be in #ParksCanada #TerraNovaNationalPark #DarkSkyPreserve for a couple of them, and captured this scene.

Those red chairs are great for meteor observing (I saw one decent sporadic that night).

The M45 Pleiades Cluster

The Pleiades, also known as the Seven Sisters, Messier 45, and other names by different cultures, is an asterism and an open star cluster containing middle-aged, hot B-type stars in the north-west of the constellation Taurus. At a distance of about 444 light years, it is among the nearest star clusters to Earth.

Thought I'd make my first post here one of my recent astro photos, which is also my profile header picture. This is the Rosette Nebula, also known as NGC 2237, which lies 5,000 light years from Earth.

Processed the not-quite-an-hour of data I took on NGC7023 the other evening.

It's a target that needs a lot of time - there's a lot of faint nebular and dark gas that's at best hinted in my result. I've also stretched the data to hell and back, so the noise is epic. I'll get back out with the telescope soon - fingers crossed.

#SkyWatch #Astrophotography The #CrescentNebula is an emission nebula in the #Cygnus constellation. It formed 250,000 to 400,000 years ago when fast stellar winds from a hot WR star collided with slower moving winds expelled by the star when it exploded into a red giant. It lies 5000 light years away, which means that the light from the red hydrogen and blue oxygen of the object took 5000 years to reach the sensor of my camera. #StillLearning

Please enjoy these space photons that traveled thousands of years just to crash into my camera sensor. #astrophotography

Getting tardy here as it’s just past midnight and I haven’t posted for #AstroTuesday. Here’s a great photo of the Milky Way taken in Mongo National Park, NSW

Here's a lovely infrared view of the IC2631 #nebula, also known as the Chamaeleon Cloud, taken with ESO's VISTA #telescope in #Chile. At infrared wavelengths we can peer through cosmic dust and see details hidden in images taken in visible light.

Just popped outside, sky's looking quite pretty right now... Shot on my 6yr old #OnePlus5, tweaked with #lightroom app.
