Description:

Starry Landscape Stacker makes it possible to produce landscape photographs taken at night that have both low noise and stars rendered as points. It does this by compositing several images taken in rapid succession, shifting the sky as needed to align the stars. A free trial version is available on the developer's website.

Release Notes:

- Added compensation for the color shift with dark frame subtraction when using cameras with a strong color cast to the dark frames.

- Improved image classification when there are strong bursts of light in some light frames such as a car driving through the scene illuminating trees.

- Improved image alignment in cases of low contrast or small areas of sky (e.g., gaps through trees or bridges). This improvement comes at the cost of increased time to align images with low contrast (e.g., fog, haze or very bright sky) or few stars (less than 100 visible). In extreme cases the time to align the images can increase by a factors of as much as 5. This cost is likely worth it as it can make the difference between an unusable image and a usable image. In the typical case there is no change in run time.

Version 1.0.6
Review by Adam Woodworth

Amazing tool! - This program is excellent! It is easy to use and makes stacking, aligning, and blending multiple star shots a breeze. The result is far less noise and pinpoint stars if you take short exposures of the sky. I use a Nikon D800E and if I take 10 exposures each at ISO 6400, f/2.8, 14mm, for 10 seconds each, the result is pinpoint stars and much lower noise then I would have seen with a single ISO 3200 exposure of 25 or 30 seconds. This program respects your input images’ color space and bit depth, so you can import 16-bit TIFFs in the ProPhoto RGB color space and the result will be a 16-bit TIFF in ProPhoto RGB.

Version 1.3.1
Review by Jlharri

Once it finished… - Once the program finished stacking 3 tif files (5568x3712) — took almost 45 minutes — the results were very poor. Its automatic detection of stars was incomplete (roughly 66%) and depended on manual identification for completeness. Hand-identifying dozens of stars might be worth the effort if the results were decent. There was odd blotchy block-shaped regions in the sky. The result was unusable and provided no value-add other than doing post-processing in Lightroom. Bottom line: save your money.

Review by White500

It really works! - This software is easy to use and produces very good results, better than other noise cancelling programs I’ve tried. It produces a composite image stacked from a series individual images. In my case, it also removed unwanted light trails from aircraft and satellites to leave a stars only image. Highly recommended for Mac OS astrophotographers.
