Starry Sky Stacker is an efficient and user-friendly program that currently costs $25 in the app store. You can also stack these deep sky images in Starry Landscape stacker, Deep Sky Stacker, Pixinsight and even Photoshop to name a few. Starry Sky Stacker, from the developers of Starry Landscape Stacker, is a Mac-only image stacking program that allows you to stack, or combine, images of deep-sky objects taken with a star tracker to reduce noise and enhance detail.

This feature alone makes the software worth the price. The preview image will always be the one with the lowest quality ranking. If you adjust the slider, it will keep that adjustment for future photos.

Be sure to check the вЂњDisplay the image classification table after openingвЂќ dialog box. The export dialog box from Lightroom.Once you open Starry Sky Stacker, youвЂ™ll be prompted to select your images. LetвЂ™s Get StartedTo get started, IвЂ™ve exported all of my images as 16-bit, uncompressed, TIFF files from Lightroom since Starry Landscape Stacker does not support RAW files.

Light frames are regular night sky exposures. The Lights, the Darks, and FlatsStarry Sky Stacker supports Light, Dark and Flat frames. Left: The import dialog box showing the classification checkbox.Right: This box lets you adjust the image classification in case the program made a mistake. In my experience, the software usually does a good job, but sometimes itвЂ™ll throw you a curveball! ItвЂ™s worth your time to double-check the classification.

Flat frames are shot at the same ISO, aperture, focal length and focus as your light frames. If you leave your rig set up until morning, you can use a clear blue sky to take your flat frames. Flat frames will remove this vignetting. What is a Flat Frame?If youвЂ™ve ever taken a photo of a bright blue sky, you might have noticed that the lens naturally vignettes in the corners. Bias frames are not supported. Flat frames remove vignetting.

What is a Dark Frame?Once you start doing deep-sky imaging, youвЂ™ll quickly learn the importance of dark frames. You can shot more or less if you wish, but I usually stick with 20. Keeping the same setting mentioned above, take a series of 20 flat frames. Put your camera in aperture priority mode this will let the camera choose your shutter speed. I then put this directly over the front of my lens. YouвЂ™ll want a bright light that evenly illuminates your frame.Instead of waiting for the morning, I like to pull up an all-white screen on my iPad and turn the brightness to 100%.

Any data in this image that is not black does not belong and is subtracted from your light frame. Blocking the light from the sensor will create a black, or вЂњdark,вЂќ frame. After youвЂ™re done taking your regular light frames, donвЂ™t touch anything, put the lens cap on and take a series of dark frames. The difference between your light frames and your dark frames is the lens cap.

Attempting to open the same 145 TIFF files in photoshop would have been a nightmare. With my modest 2017 MacBook Pro, this process didnвЂ™t take long at all. So, this will depend on how many images you have and how powerful your machine is. Double-check the classification of your frames.The importing, aligning and sorting process can take some time.

Starry Sky Stacker will composite the images and give you the option of which stacking algorithm you want to use. If the image displayed has star trails, you can choose to exclude it by clicking the exclude button or by sliding the quality slider to the left.Happy with what you see? Hit composite! ItвЂ™s that easy. Instead, you see the photo with the lowest quality ranking from your selected images. Keep in mind, at this point you do not see the stacked image.
