I captured two and a half additional nights of data on NGC 7822, this time with a different dual narrow-band filter that captures the Oxygen III emission line in the green and blue channels of the camera and the Sulphur II emission line on the red channel.

Combining this new data with the original data (Oxygen III and Hydrogen Alpha), I produced an SHO image where the Sulphur II, Hydrogen Alpha and Oxygen III emission lines are assigned to the the red, green and blue channels of the image respectively.

In total 13h 30m of data, 5h 5m on the Oiii+Ha filter and 8h 25m on the Oiii+Sii filter.

Here is a 3.3 x 2.2 degrees field of view in the constellation of Cepheus that includes many objects; the Lobster Claw Nebula (Sharpless 2-157), the Bubble Nebula (NGC 7635), the NGC 7538 emission nebula and the Sharpless 2-161 H II region, as well as the Messier 52 and NGC 7510 open clusters.

The data was captured under bright moonlight on three nights between August 27 and September 3. The moonlight made the data noisy and difficult to process.

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.

Two goals for the evening:
- Set up
- Try out the new lens heater

Gonna start slow with some wide angle shots, no particular target just to get back into the hang of things.

Clear skies all the other folks who gonna head out tonight :)

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 ma 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.

The Eagle Nebula (IC 4703, aka M16) in the Serpens constellation shot over two very short June nights.

At the heart of the Eagle Nebula are the Pillars of Creation made popular by the Hubble space telescope (1995 & 2015) and also later shot by the James Webb space telescope. Although not as detailed and spectacular as the images from these large space telescopes, It's surprising what an amateur can armed with a 0.072m telescope, a lawn chair and a laptop ;)

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.

The Elephant Trunk Nebula (IC 1396) in the Cepheus constellation.

A short night of astrophotography under the full moon yesterday night. I was mostly going to gather some hydrogen alpha (Ha) signal on the red channel of the camera which is less affected by the moon glow but I decided to try processing the RGB image anyway.

This is not my best image by far but I'm glad how it turned out considering the capture conditions. I am looking forward to combine this data with future data from a longer night with better sky conditions.

A widefield shot in the Cygnus constellation that includes the Crescent Nebula (NGC 6888).

This field of view is located just south (in celestial coordinates) of the Gamma Cygni (Sadr) star at the center of the Cygnus constellation, also known as the summer cross.

This image was shot on May 27 during the first night out with friends from the local astronomy club.

Another widefield shot, the Iris Nebula (NGC 7023) and the surrounding dust clouds in the Cepheus constellation.

Contrary to emission nebulae which consist of ionized gases that emit light, this is a reflection nebula; interstellar dust clouds that reflect the light of surrounding stars. Given their faint luminosity, emission nebulae are challenging to capture and required dark skies with low light pollution and no moon glow.

This image was captured under the new moon, from the dark skies (Bortle 3) of the La Mauricie National Park in Québec 🇨🇦.

A widefield (4.8 x 3.2 degrees) view of the Tulip Nebula (Sharpless 101) and its surroundings in the Cygnus constellation shot on May 22.

This area of the Cygnus constellation is filled with emission nebulae as well as dark nebulae; interstellar dust clouds that block the light from the emission nebulae.

With an approximate distance of 6000 light years from Earth, this field of view covers approximately 400 light years across.

Capture equipment: Askar FRA 400 astrograph (400mm focal length, f/5.6), ZWO ASI183MC Pro RGB camera with Optolong L-Enhance light pollution filter. Capture software: Kstars, Ekos and PHD2 (Astroberry image) running on a Raspberry Pi 4. Processed in Pixinsight.

The Messier 106 galaxy (M106) and some of its neighbours in the Canes Venatici constellation shot over 1-1/2 nights on April 15 & 16.

M106 is approximately 22-25 Million light years from Earth and is part of the Canes II group of galaxies, which is part of the Local Supercluster. It is comparable in size and luminosity to the Andromeda galaxy, though ~10 times more distant, hence its smaller apparent size from Earth.

This image is composed from a stack of 90 x 300s sub-exposures (7h 30m total). Captured with an Askar FRA400 astrograph (400mm focal length, f/5.6) and a ZWO ASI183MC Pro RGB camera with an Optolong L-Enhance light pollution filter and using the Kstars/Ekos and PHD2 software (Astroberry image) on a Raspberry Pi 4. Stacking and processing with Pixinsight and Darktable.

Habe heute einen NiPoGi GK3 Plus Mini PC, 12th Gen Intel Alder Lake-N95 Prozessor bekommen. Ich will als Ersatz für meinen PI4 verwenden und habe Ubuntu 22.04 bzw. Debian bullseye installiert.
Unter Ubuntu mag die Netzwerkkarte mit dem rtl8168 gar nicht.
Unter Debian geht sie, dann gibt es aber Probleme mit dem X-Server.
Installiere ich unter Debian den neuesten Kernel 6.1 geht der X-Server, aber nicht mehr die Netzwerk-Karte.

Ich habe es erst heute entdeckt: am 13.04. soll X OS erscheinen.
Nachdem scheinbar nicht mehr weiterentwickelt wird, werde ich mir es mal genauer anschauen.
Eigentlich schade, weil mir gut gefallen hat. Aber seit einem halben Jahr hört man nichts mehr vom Entwickler.

Messier 81 (M81) - Bode's Galaxy, a grand design spiral galaxy and Messier 82 (M82) - Cigar Galaxy, a starbusrt galaxy.

The M81 and M82 galaxies are part of the M81 Group in the Ursa Major constellation. The M81 Group is one of the nearest to the Local Group and is part of the Virgo Supercluster.

This image is composed from a stack of 150 four minute sub-exposures (10h total) I shot over two nights on March 11 and 24 from a Bortle 6 (bright suburban) light polluted sky. Imaging equipment: Askar FRA400 refractor telescope, ZWO ASI183MC Pro RGB camera and an Optolong L-Pro light pollution filter on a HEQ5 mount.

Captured with Kstars, Ekos and PHD2 on Astroberry. Processing with Pixinsight, StarNet and Darktable.

Starting a third night of capture on M81 & M82. Trying to get the most of these rare moments without clouds or moon glow.

finally back at imaging, first time using on my raspberry pi instead of arch linux arm!

Really impressed so far with how well works

A return to winter after interminable days of rain and mild weather.

The telescope is out and capturing data. I'd neglected to keep kStars up to date, and the comet catalogue was throwing some weird errors, but after a quick update to version 3.6.0 I now have C/2022 E3 (ZTF) available so will hopefully get some data later tonight...

My professional setup :-)

Jackery powerbank, the pi4b w/o case, and some cables. Now gotta decide if I want to use scope w eyepiece camera, or my canon 7d w a light grabbing lens. The 7d was recognized by the pi4 software, so that's good!
