It was also the first time I tried using a tablet instead of a laptop to remotely control the Kstars/Ekos & PHD2 software running on the Raspberry Pi attached to my astrophoto rig over VNC.
Although Kstars/Ekos are not designed for tactile use, I found it perfectly functional with the way the VNC client uses the screen as a big touchpad and allows for zooming.
Also, combining the use of the tablet's "night mode" and "extra dimming" feature with a contrasting color theme in Kstars allowed for a visually comfortable experience with little blue light that would otherwise ruin night vision.
I will probably keep using the laptop for initial setup but then use the tablet to monitor and make adjustments when required.

Very likely my last image of 2023, this is the Jellyfish Nebula (IC443), the remnant of a supernova in the constellation Gemini. The two large orange stars are Mu and Eta Geminorum, two red giants at the feet of the rightmost of the two "stick figures" that form the constellation Gemini.

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).

Here is the result of combining the narrow band Hydrogen alpha data I captured Wednesday with the broadband RGB data of the Andromeda Galaxy (Messier 31) I captured earlier. The Hydrogen alpha narrow band signal (red) helps bringing out the emission nebulae in the galaxy arms.

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.

Yesterday night I captured a little over five hours of data on the Andromeda galaxy (Messier 31) with a dual narrow-band filter that captures the Oxygen III (cyan) and Hydrogen alpha (red) emission lines. Below is the result of stacking the best four hours and six minutes with minimal processing (stretch, basic colour calibration and a hint of saturation boost).
While the galaxy is a broadband target, the goal of using narrow band filters is to better isolate the emission nebulae inside the galaxy. Here, the Hydrogen alpha regions can be seen in red in the galaxy arms.
When I have a bit of time, I will combine this new narrow band data with the RGB data I captured a couple of weeks ago. The result should have enhanced colours in the Ha regions.

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.

Clear skies are too precious to waste, even if it's the full/super/blue/whatever moon.
Luckily, narrow band filters help making the data collected under moon glow usable.
I can see details of the Bubble Nebula in the individual sub exposures so hopefully I'll be able to process this into an acceptable image.

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.
