I'm so pleased to have been able to capture the Zodiacal Light for only the second time, and this time I was able to get the entire cone rather than just the bottom.
Zodiacal Light is caused by sunlight being forward scattered by interplanetary dust grains. It can be seen on a moonless night in the west after sunset during early spring, or in the east before sunrise during autumn.
It wasn't something I could see visually but it was showing up faintly on single 25 second exposures, so I decided to take a few photos and stack them. On the right hand side, the elongated smudge is M31 the Andromeda Galaxy. I checked Stellarium for the position and my cone of light is in exactly the right place.
Photos were taken from about a mile outside of my village in North Oxfordshire where there are no street lights at all. I used a Canon 1100D with Canon 10-18mm wide angle lens. I took 9 x 25 second shots taken at ISO-3200 f/4.5. I stacked them with 12 darks using Sequator. The cloud was thickening up soon after this shot was taken so I couldn't grab many more shots.
Processing was done in Photoshop CS2, Lightroom and Fast Stone Image Viewer.
This was a "bonus shot" from my early morning out on 4/2/2020; my second stop (of three). I wanted to grab a shot of this, but I also wanted to be quick about it, as I was hoping to get to another location to shoot before dawn. (This was unplanned, just happened to see it and stop.) I decided to skip setting up the LED panel for low level lighting and hoped there would be enough ambient light from the nearby small town (although it was now a few more miles behind me). I ended up having to push the shadows a little more in post and thus, even with stacking, still got a little more noise than I'd like.

I was able to get my 6 year old son out to WV for a long weekend of fishing rivers, hiking, and Milky Way Viewing. This was his first time really seeing the Milky Way under such dark and clear skies. Hopefully made a core memory!

The Zodiacal Light - the beam pointing towards the Pleiades. 10, 15 second shots stacked in Sequator = 2 minute 30 seconds of exposure. Rokinon 14mm, f2.8, ISO 6400, Nikon D850.
From Wikipedia: The zodiacal light is a faint, diffuse, and roughly triangular white glow that is visible in the night sky and appears to extend from the Sun's direction and along the zodiac, straddling the ecliptic. Sunlight scattered by interplanetary dust causes this phenomenon. Zodiacal light is best seen in the Northern Hemisphere during twilight after sunset in spring and before sunrise in autumn.
The zodiac is a belt-shaped region of the sky that extends approximately 8° north or south (as measured in celestial latitude) of the ecliptic, the apparent path of the Sun across the celestial sphere over the course of the year.
The beautiful emission nebula Gamma Cygni and the Crescent Nebula captured on June 5, 2021 from my back yard in Pennsylvania. I used a Nikon D750, Nikon 300mm f/2.8 lens, and an AstroTrac. The subs were shot at ISO 1600 & f/2.8. Processed using Rawtherapee, Sequator, RNC-Color-Stretch, & Photoshop.

This is the first record I make of the "Helm of Thor" nebula (NGC 2359). The stacked frames, captured in four nights, totaled 10 hours and 30 minutes of exposure.
"NGC 2359 is a helmet-shaped cosmic cloud with wing-like appendages popularly called Thor's Helmet. Heroically sized even for a Norse god, Thor's Helmet is about 30 light-years across. In fact, the helmet is more like an interstellar bubble, blown as a fast wind from the bright, massive star near the bubble's center inflates a region within the surrounding molecular cloud. Known as a Wolf-Rayet star, the central star is an extremely hot giant thought to be in a brief, pre-supernova stage of evolution. NGC 2359 is located about 15,000 light-years away in the constellation Canis Major". Source: NASA (science.nasa.gov/ngc-2359-thors-helmet)

Las nebulosas son tan famosas quizá porque se identifican con formas familiares, al igual que los gatos lo son quizá porque se meten en problemas. Sin embargo, no se conoce ningún gato que pudiera crear la enorme nebulosa Pata de Gato visible en Scorpius. La Pata de Gato se encuentra a 5.500 años luz de distancia y es una nebulosa de emisión con un color rojo que proviene de la gran abundancia de átomos de hidrógeno ionizado. Conocida también como la nebulosa Zarpa de Oso o NGC 6334, contiene estrellas de casi diez veces la masa del Sol que han nacido en este lugar durante los últimos millones de años.
La imagen es una fotografía de campo profundo de la nebulosa Pata de Gato, fue capturada en los oscuros cielos del Cajon del Maipo el pasado 12/05/2019.

Galactic Center single shot and stacked. Experimented with stacking multiple exposures to reduce noise and increase detail. Definitely increased detail. Need to work on the noise reduction some more. I shot these without a tracking mount a couple summers ago at Observatory Park in Geauga County, Ohio. The stacked version uses 5 light frames plus 5 dark frames, 15 sec. ISO 4000, 24mm f3.5 stacked using Sequator (my 1st time) and processed in Lightroom. The trees along the bottom were layer blended in Photoshop from a single exposure.

My rule was to check for fuzzy objects in the sequator output, *then* look them up on the World Wide Telescope
So it took me almost 5 years to get back to this location to "give it another go". I first shot this with a friend back in July of 2016 (and I believe we were the first ever to shoot this at night). I've wanted to go back for quite some time since I've upgraded my equipment, my nighttime shooting skills and my editing techniques. This past weekend I had the opportunity while we were spending some time with some friends in Ruidoso, NM. It had been cloudy and had rained for the better part of the day on Friday but by the time it was getting dark, the skies had cleared so my wife and I made the trip over to get a few shots. The drive from Ruidoso to Cloudcroft is quite beautiful during the day but at night? Well, I wouldn't recommend it. We saw probably somewhere between 30-40 elk along the road, on the road or crossing the road and only passed 1 car (going the other direction).
This location would rate as "moderately difficult" due to a couple of factors. First I spent a great deal of time trying to get my LED panel (on a light stand) set up in such a way to get the trestle lit and the trees behind it as well. Depending on the position it was to bright or too dark or the trees in the foreground were way too bright. I end up compromising the position and making some adjustments in Photoshop (burning in the brighter areas) in post. Then there are the cars/trucks going up and down the mountain at a completely unpredictable pace. No big deal if you're only shooting single images, but if you're trying to shoot a sequence to stack? Well, it's tricky at best.
On a side note (for anyone wondering or anyone who actually read this far), I believe the light trees (kind of a yellow/orange glow) just above the trestle may be coming from a water treatment facility just up the road. The light on the tops of the trees on the left V of the horizon/tree line would be from the small town of Cloudcroft, NM.

The image shows the center of the Milky Way majestically above the ship Albatross in Damp. The town of Damp is located on the Baltic Sea coast in northern Germany and is known for its picturesque location and maritime history.
The Baltic Sea coast offers a stunning daytime backdrop with its clear blue waters and rolling hills in the background. At night, the expanse of the sea creates a dark sky in which the Milky Way can even be photographed from the illuminated harbor promenade.
For the picture, 7 individual shots were used with the following settings:
ISO3200
F/3.2
10 seconds
11mm (APS-C)
All images were stacked with the free software Sequator and the resulting image was then edited in Lightroom.
I have been promoting noise reduction by stacking for years, but while I was able to recommend "Starry Landscape Stacker" for MAC users, there was no easy to use Software for Windows.
This has changed lately, with the release of SEQUATOR, a very easy to use program for stacking untracked nightscapes (for noise reduction) and the best of all: It is freeware!
sites.google.com/site/sequatorglobal/home
So far, I have been using fitswork, a dedicated software for stacking tracked star images. While I learned to use it for untracked images as well, this process is painfully slow. It would therefore be immensely helpful if SEQUATOR was able to perform as beautifully as fitswork, without all the slow manual interventions needed…
Today, I was able to do my first test of SEQUATOR. To see how it performs, I did a side by side comparison with an image I already processed with fitswork.
First I had to find an untracked image sequence. I have been doing mainly tracked shots lately, but I found my Bisti Eggs image which I shot from a fixed tripod:
To get a meaningful comparison, I decided run SEQUATOR with the same preprocessed TIFFs I have used for stacking in fitswork and publish some 100% crops taken from the resulting TIFFs right out of SEQUATOR and fitswork and without further processing. SEQUATOR has several options for stacking, but I found that “Freeze Ground”, “Auto Brightness OFF” and “High Dynamic Range ON” worked best for me.
As you can see, SEQUATOR does an extremely nice job. There are no star trails and no stacking errors and I really like how the foreground and the horizon are razor sharp. Very impressive indeed!
On closer scrutiny, the SEQUATOR result has a tad more saturated colors than my fitswork resut, but selecting “High Dynamic Range ON” avoided burning the stars. The increased saturation leads to slightly increased color fringes around the brighter stars, but this would have happened with the fitswork image as well during post processing and there are techniques to reduce this effect during processing.
SEQUATOR is really easy to use and it took me less than 5 minutes to produce the result, while my normal workflow in fitswork takes about 3 hours to arrive at the same stage.
Conclusion:
I can highly recommend SEQUATOR! If I ever have to process an untracked image sequence again, I use SEQUATOR instead of my fitswork workflow.
On Windows, it is by far the easiest to use and fastest stacking software for nightscapes and produces very good results. Even beginners can immediately produce excellent results. There are no excuses anymore for noisy single shot nightsapes… ;-)
PS:
1. Of course I still highly recommend using a tracking mount to achieve “deeper” sky exposures, by using lower ISO and higher exposure times. This means that you have to shoot the foreground separately with your tracker off and merge the two exposures during post processing. For this techique SEQUATOR might not be the best software out there, but to stay fair, that is not what it was built for…
2. Here is a very nice quick tutorial for SEQUATOR. The only point where I disagree with Mike, is that for better sharpness and no burned highlights, I recommend to use HDR instead of Auto Brightness.
