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)

This group is also some of my first two attempts with 'focus stacking. A couple are random photos that I had two similar images of that I then stacked in the software (Helicon Focus). The rest are from a IACC (local photo club) workshop with light boxes and rock quartz slices that I did repeat images of (tripod used) with changes to the F-stop to change (or expand) the focus via DOF. I then processed the groups to see what additional focus depth might appear. The software also has a 3-D tool that I like but have not managed to duplicate for viewing so far. The double images are a snapshot of one small portion of the 3-D workflow. Does anyone have experience or suggestions with 'focus stacking' or 3-D modelling that might be helpful to me and others out there? The ‘focus stacking’ is especially helpful for those of us that are trying macro and close up photography. Thank you.

While walking along Sunset Beach in Vancouver, I found a lot of rocks stacked up in a weird way. Some people said they're miniature inukshuk's, but they're kind of missing the arms and legs... But they were still very interesting none the less.
Anyway, I'm slightly disappointed that I didn't get more of the sky and that warm light though.
Stephan’s Quintet can be found in the constellation Pegasus, the apparent magnitude of these galaxies hovers around 14.0, making this a tough object to capture. This group of galaxies was discovered by Edouard Stephan in 1877 at Marseille Observatory. Although referred to as a quintet, only four of the five galaxies are interacting with each other at a distance of about 300 million light years! NGC 7320 is actually much closer at a distance of “only” 40 million light years.
IMAGE DETAILS: Images were taken over two nights of testing with the Celestron mount. A total of 38 minutes of exposure time (20-second subs at ISO 6400) using my Meade 12″ LX90 telescope and Canon 6D camera. I used DeepSkyStacker for stacking the subs and ImagesPlus for image stretching.

Ok, next post will be something cuter, I promise. Until then here is another ground beetle stack. Please see last post for more details!

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!

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.

More cute little frogs from my SIL's place, stacked to look cheery with their funny grinning mouths. It took me several goes at stacking the frogs, they just didn't want to co-operate....

This is a single frame image with about 20 images stacked again as per the previous images. These are 30 second exposures which give a smoother water but slightly more harsh highlights. Still looks alright to me.
