Day 284
My wife has carefully balanced these pumpkins in the backyard. You think I'm going to let that pass? The bottom one looks like it's getting squished.

Macro 1:1. Focus stacking. Sony A7II (ILCE-7M2) with Tamron SP 90mm F/2.8 DI Macro 1:1 VC USD (F017E). Wide open shot f/2.8.

Found this cool little spot where tradition was too stack rocks i'm assuming.

Iain and I took dad to the Kelvingrove Museum and Art Galleries during the holidays. I love this place and could spend hours just walking around it. We are incredibly lucky to have a wonderful place on our doorstep.
A photo-stacked version of the 232 individual images that went to make up the time lapse video. The images were taken at ten second intervals.
Well this is going to be one of my little projects this Winter, focus stacking Collembola, with this I decided to try using my 1.4x teleconverter and my MP-E at x5, so in all this was a x7 magnification handheld focus stack of just 6 images at F/6.3. I'm hoping to get deeper with the stacks as the Winter goes on.
It really is a very hit and miss affair with these guys, sometimes they will stay perfectly still and then sometimes they are always moving, especially those antennae, but I was reasonably fortunate that this female stayed put for just long enough, anyway an ongoing project and with the numbers increasing I think it quite achievable, the main thing is refining the technique :o)
I hope everyone in the Southwest has a safe day, apparently going to get very wet again and then I hear that next week temps are going to drop to -15C, well at least it will slow down the Globular Springtails a bit LOL :o)

The Bethlehem Steel Corporation was an American steel and shipbuilding company that for much of the 20th century was one of the world's largest steel producer and shipbuilding companies. The company's roots trace to 1857 with the establishment of the Bethlehem Iron Company. Bethlehem Steel was formed in 1904 through the merger of the earlier companies, and existed through the decline of American steel manufacturing during the 1970s until its final bankruptcy in 2001.
The Steel Stacks were preserved as an Icon of the Steel Industry and are now part Arts and Entertainment center

The swell ended up being more mild than I thought. Still was happy to snag this pano on the way to a clients office.
I need to get down to the gong when it is really pumping. This was a 4.6m swell but coming from the south so the headliand blocked it.

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.
