It's really hard to predict when a sunset will be good for stacking. I thought that last time lapse would come out well in lighten mode, but actually darken mode worked better. This picture is the result f keeping the darkest pixel at each point of the previous time lapse video (and then boosting brightness and colors, which tend to come out dark and muddy from all the blending). You can also see the paths of a bird and a rower on the water.
This is a Timestack from back in Chicago that I hadn't posted at the time (I posted another version with fewer frames stacked).
A set of short exposures digitally combined produces an hour’s worth long exposure, that reveals the diurnal motion of the stars due to the Earth’s rotation and creates the beautiful star trails over the small church on top of a hill in the countryside. The pivot point in the North Hemisphere is the star Polaris at the end of the Little Dipper asterism, where the projection of the earth’s axis on the celestial sphere is currently pointing.
Thanks to everyone for visiting my photos and the kind comments, wishing all health and clear skies!

Lesson learned: Never use a zoom lens for star-trails! Originally, I had 115 frames, only to find out that the lens shifted its focal length during the night and the stack had curved arcs instead of circles.
Thanks to everyone - clear skies!
The 2020 Perseid meteor shower was a great light show. The lights on the right are from a small town called Big Pine and the line of lights on the bottom are from vehicles on highway 395.
Star Trails taken at Bow Fiddle Rock Moray Scotland. Taken under unbelievably bright moonlight. A good atmosphere on the moonlit shore...... cold though.
Stacked it in my favourite "Comet Mode" on Starstax 7.
For group theme 52 Weeks of 2016.
Theme: Astrophotography /night photography - technique.
58 x 30 second exposures blended in StarStax - then tinkered to the max. The orange colour courtesy of good old north east light pollution! :-)
Another thing you can do from your comfort of your own home, Startrails!
Set off the Time Lapse app on my Sony A6000 at the weekend before going to bed and it managed to capture over 400 photos before the battery ran out.
Used Starstax and only 100 photos to create this 'meteor' storm photo over Prestwick...
Trying to catch shooting stars in the perseids meteor shower night at Sa Ràpita beach, without luck (no one in almost 2 hours there).
At least I could to do the startrails with StarStax adding 346 photos, between 22:45h and 00:05h, taken with 8 seconds of exposure time, f/1.6 and ISO-400. Canon EOS 6D y Sigma Art 20mm 1.4
This is another timestack of the sunset from Aug 1st, but this time using a much smaller sunset of frames to get a different look.
A timestack means blending together a bunch of frames from a timelapse so you can see the motion in one photo. It gives the effect of a very long exposure but is much easier to do since you don't have to worry about washing out the photo or anything like that.
Photos taken with Sony Nex 5T and stacked in StarStax.
Startrails: 275 Aufnahmen - 25 Sek bei f/2.0, ISO 1600, 14mm verrechnet mit Starstax.
Vordergrund: 2 Aufnahmen 38 Sek bei f/8.0, ISO 400, 14mm mit Sequator verrechnet.
This is a timestack of 411 frames of last night's sunset, taken at 3 second intervals. I took the photos with my Sony Nex 5T using the timelapse app, and then I stacked them in StarStax.
Yesterday was very windy and the tripod situation on the roof was really challenging. Earlier in the day I set up my new full size tripod at full height aimed over the railing, with a jug of water as a weight hanging from the hook, and it got blown over by the wind. It also had a rain cover on at that time which I think might have acted a bit like a sail. So for the sunset, I set up the tripod much lower, aimed through the bars of the railing (which limits the field of view more), and set it just high enough to hang the jug of water. I'll post behind the scenes photos later. Anyway, I think the wind wasn't quite as strong at sunset as it was when the storm was coming, and I also made the setup more steady, and it seems to have worked - there aren't any obvious jiggles messing up the stacking.
I also tried to set up my iPhone and it was way too windy, the results were useless. Does anyone know a good tripod for seriously clamping an iPhone enough to hold steady in heavy wind?
Once I got the tripod set up, I sat back in a lawn chair and did some work on my iPad while the timelapse ran. I think the sunset inspires deep insights, or at least I hope so.

Thank You Katrina and Adam.
A "stack" of 66 images each 25s at f/2.8, ISO 1250. Canon EOS 5D Mark III camera w/ Canon EF15mm f/2.8 "fisheye" lens for an effective 30 minutes or so of star trails.
All was calm, all was bright on a beautiful new moon night. Light pollution from De Pere and Green Bay, due north, quite evident.
Time stack at Hill of Towie windfarm on a stunning morning. I have been practicing using the time stack method that I use for startrail photography during the day to create interesting effects. This photo is made up of 427 Exposures stacked in Starstax. This was a re visit to Hill of Towie Windfarm, last time I was here I was doing daytime Single long exposures.
Stats for this Shot;

A Reworked image made up from a series of RAW files from The Huntly Castle startrail. Made from 145 exposures of 30 Seconds. Images blended in starstax 7. The lighting came from a handful of sodium streetlamps that were nearby. They added to the atmosphere :-)

I wasn't sure if I even wanted to post this one, because it's out of focus. But, I decided to post it anyway, to ask for any advice from anyone who shoots star trails with this camera.
I used my Sony Nex 5T, and I did my best to set focus by auto-focusing on some far away lights across the lake, using the focus-peaking on the screen.
I have successfully done star trails before, with a point and shoot canon and the chdk scripts. The problem is, this camera does not have any kind of easy infinity-focus like my old point-and-shoot does. So, any advice on focusing on stars?
Also, I used the timelapse app. The longest exposure it seems to allow is 30 seconds, and I'd rather do something longer. There's a bulb mode which I haven't tried, but I don't see how to automate that with a timelapse type thing.
There IS a Star Trails app for this camera, but the reason I didn't use it is that the description says it only produces a video of star trails, and does NOT save the separate frames for you to process into a star trails photo.
I also have since gotten a Sony a6000, which is similar, but has an optical viewfinder - does that help with nighttime infinity focus?
The problem with travel is you only get one try, so this is what I got. But hopefully I can try to perfect this technique closer to home.
As usual, another night of star trails - but this time I wanted a blend of techniques in a single frame.
I added a bit of life to this abandoned Dodge bus using basic light-painting to bring out the interior glow and highlight the details.
The foreground (bus + landscape) is made from 8 stacked exposures to reduce noise:
ISO 800 / f/2.8 / 75 sec
The star trails are created from 1,200 photos, combined with StarStax:
ISO 800 / f/2.8 / 5 sec / 5 sec interval
In total, the sky exposure adds up to 3 hours and 20 minutes, until clouds finally rolled in and I had to stop shooting.

Bit of editing fun with a recent star trail image processed with comet style with added lens flare for effect

The gélas, the relatively flat mountain on the left, is, at the border between France and Italy, the highest mountain of the Cote d'Azur at 3143m.
This is the view you have when you start your walk to that mountain, from la Madone des Fenestres, well, if you start at night and you stair at it for a while ;)
