Tutorial: Stacked Astrophotography Panoramas

This video tutorial combines two of my favorite techniques for maximizing image quality of astrophotos: stacking and stitching.

Video Tutorial

Two of my favorite technigues for improving the quality of astrophotography are highlighted in my tutorials for stacking and stitching. Over the last year, I’ve been testing different workflows to combine these two techniques together in order to truly maximize the image quality of my astrophotography. Creating a stacked panorama is now my personal favorite technique for shooting astrophotography. Check out my workflow in the tutorial below:

Gear

For your camera and lens, I recommend simply using a standard prime like a fast 50mm or similar. The mildly longer focal length and fast aperture that are typical on a standard prime will make for an ideal light gathering tool for this technique.

I also highly recommend a simple horizontal panorama head in order to make the shooting process easier. It’s not a requirement but it has certainly made shooting these massive panoramas much simpler. Here’s what I used:

Sony Zeiss 55mm/1.8 (B&H)

Desmond DLEVX Leveler (B&H)

  1. Nice tutorial as always. I’ve been using this technique on a few images for a while but you showed me a couple new things with stitching which is super cool.

    I’m wondering about the dpi of the stacked/exported images.

    I’m seeing 72dpi on the exported images, but the images I imported were 240dpi (im using a Sony A7s).

    Am I losing resolution with Starry Landscape Stacker? I’m beginning to print my images much more and this is why I’m wondering.

    1. DPI is a concept that applies only to print size. If your overall resolution pixel dimensions do not change, the image will still have the same resolution. In this case, SLS may be exporting at 72dpi but that just means that the print dimension is larger… not that you’ve lost resolution. So… basically you have nothing to worry about.

  2. Another great video.

    I played with this over the summer. I used groups of three, with dark frames. That seemed to give good results and minimized alignment problems

    1. I’ve actually tried it with success with up to 8 exposures per position but it’s best if limited to a smaller number of positions for the panorama.
