4/27/2024 0 Comments Sequator photo stacking software![]() I found a different tool named Sequator, that is simpler than DSS and does a great job in creating a final image without additional steps. But it is very tricky, and I never obtained good results. We can manually align the sky region of all the layers, and then do as mentioned above. we are rotating, but just for you to understand. But it is not possible to use it for the sky, because the stars are rotating (well. This technique works great for foregrounds, because they are "static". Just to make the long story short, you have to open all the images as layers in Photoshop, align all the layers, convert them to a smart object, and select the stacking mode as "mean". Use Sequator to merge the shotsĪs you probably know, there is a technique that could be used in Photoshop to merge many identical shots, in order to reduce the noise due to high ISOs it is called "mean stacking", and I already described it here. Pros: it is a free software, very famous for astrophotographyĬons: this software is not so user friendly (too complex and too many options for my taste) very very slow the output image is perfect for the sky, but the foreground will be "scraped": you have to do something different for the ground, and then create a composite. Moreover, depending on the lens you are using, you do have to align the sky shots manually, and it could be a mess. The results are generally goodĬons: You need to take multiple shots you have to do al the work twice, one for the foreground, one for the starry sky. ![]() Pros: you do not need additional software. Moreover, the good software is expensive Stack multiple frames in Photoshop (see below) Pros: fast, easy to use, requires a single good shotĬons: usually, every noise reduction algorithm will remove some (many!) details too. Usually, if you really need a (nearly) noise-free images, you can do one of the following: Use a noise reduction plug-in I will try to summarize some options, and then I will focus on a new software called Sequator. The keyword here is post production there are many ways to reduce noise in a digital image, and there are pros and cons for each. Of course this is not what I want to teach you! Instead I want to show you how to get the same (more or less) result, with a low budget setup. The most easy way is to buy a professional camera. well, you do have to follow additional steps. It’ll get brighter over the next 7-10 days, may get harder to see as it approaches its December 18 pass by the sun.In the previous post, I showed you some tips to take great night sky shots, keeping the overall noise quite low.īut of course these are tips, not miracles: if you really want great details and, at the same time, extremely low noise. I could barely see the green fuzzy head of the comet at 24mm, could see it with a tiny tail at 70mm, better at 100mm. (Starry Landscape Stacker on the Mac would work, but you would want 10 identical exposures.) I “synchronized” my folder in Lightroom to find the new file, adjusted it a bit, and saved this result. I have a PC, so I used the free Sequator software to align, stack (noise reduce) and do some HDR processing on the images, saving a TIFF file. I adjusted the results in Lightroom and saved them as 100% JPGs. So I set exposure bracketing to 5 images, 1/3 stop apart. At 200mm f/2.8 I set my ISO to 12,800 and shutter speed to 2.5 seconds. From then on (300mm, 400mm) a sky-tracking mount would be best. I also tried a few shots zoomed in to 100mm & 200mm. It’s just north of due east, and about halfw2ay up in the sky (42 degrees), dropping a bit each dy on the upcoming mornings. This morning I found it in a 70mm shot, just above and to the left of Arcturus. And comets are notoriously unpredictable, so it’s best to capture photos early, and then upgrade them as it gets better. But just in case you don’t have clear skies, you might want to try to catch Comet Leonard in the pre-dawn sky to the east now. ![]() If it doesn’t break up as it approaches the sun, it could continue to brighten even further as it approaches the sun through December 18. Comet C/2021 A1 Leonard at 200mm 5:40am Sunday morning December 5.Ĭomet C/2021 A1 Leonard will probably get a lot brighter over the next week as it approaches its closest pass by earth on December 12.
