The Crescent Nebula (NGC6888) is a cosmic bubble about 25 light-years across, in the constellation Cygnus, blown by winds from its central massive Wolf-Rayet star (WR136).

This image was captured on July 26 & 28 under quite bad sky conditions; low transparency due to smoke from wild fires in the West combined with Moon illumination.

A view of the extensive H II emission regions in the constellation Cygnus, just North of the star Sadr (γ Cygni), which forms the intersection of the asterism known as the Northern Cross.

At the bottom right is the NGC 6914 reflection nebula, blue halos created by the reflection of the light from blue giant stars on the surrounding interstellar dust.

The field of view is 3.2 x 2.1 degrees, with the celestial North to the left of the image.

A widefield view of the Pleiades cluster and reflection nebula (M45) at the North-West end of the constellation Taurus. The surrounding interstellar dust in is illuminated by the blue giant stars of the cluster, giving this nice fuzzy blue cloud look.

While most images of the Pleiades focus on the cluster itself, I wanted to take a wider field image to show the extent of the interstellar dust in this area, including this long arching structure to the left of the cluster in the image.

The heart of the Heart Nebula (IC1805) in the constellation Cassiopeia.

This is the first image from my new 150/750mm f/5 Newtonian telescope, and the first image I produce in months due mostly to bad weather and some guiding issues with the new scope (resolved with off-axis guiding).

We've had four consecutive clear nights this week, a rare event! Despite being the shortest nights of the year, I managed to get a little over five hours of usable data over two nights on the western part of the Veil Nebula.

This nebula is the visible part of the Cygnus Loop, a supernova remnant in the Cygnus constellation. Located at approximately 2400 light years from Earth, the remains of the supernova that exploded 10,000 to 20,000 years ago now span approximately 130 light years across.

Visible in this image are the Western Veil nebula aka "Witch's Broom" (NGC 6960), Pickering's Triangle as well as NGC 6974 and NGC 6979.

Thursday night was the local astronomy club meetup in the field. While we were chatting and doing visual astronomy, my astrophotography rig captured the data that I later processed into this image.

This is Sh2-132 (from the Sharpless catalogue), an emission nebula in the constellation Cepheus sometimes referred to as the Lion Nebula. Its glowing gases are ionized by very hot and massive stars, including two Wolf-Rayet stars and one class O star.

How it started | How it's going

Almost OTD one year ago I started my journey down the astrophotography rabbit hole.

I took my first astronomical picture, the Andromeda galaxy (M31), with a stock DSLR, a zoom lens and a simple star tracker (Canon T7i, Canon 70-200mm f/4 and SW Star Adventurer, 176 x 60s). I was quite happy of the result and hooked into the hobby.

Fast forward one year and I shot the Andromeda galaxy again, this time with my latest process, techniques and equipment.

Did you know there were sharks in space? 🦈

This is the Dark Shark Nebula, LDN 1235 from Lynds Dark Nebula catalogue, in the constellation of Cepheus. It is a large cloud of interstellar dust that reflects the light of surrounding stars.

I captured this image Tuesday night from La Mauricie National Park (QC, 🇨🇦) where the low light pollution (Bortle 3) allows capturing this very dim object in a reasonable amount of time.

There are 5 galaxies visible in the image, can you spot them? Two are easy, three are more difficult.
