Star Stacker allows you to import a sequence of star photos taken throughout the night and turn them into star trail images or a time lapse video. After importing you can create the images and/or a time-lapse video with a few different effects. - Full trails - every star at full brightness - Faded trails - Stars get brighter as the process runs - Shooting star - Like faded trails but the last image is brighter than any previous giving a shooting star effect - Javelin - Both ends of the trail are faded - Warp mode - zooms into the image stack slowly creating a warped effect. This will also affect the foreground so post processing may be required if the images have the foreground included. You can also choose to save a video of the time-lapse based on the options used for the image stacking. Can import images from your photos app. RAW files that have been recently imported from an SD card reader, may take a few minutes before the full resolution files are available. There are resolution limits depending on the device being used and the memory it has: - 6gb - 62mp - 5gb - 62mp - 4gb - 62mp - 3gb - 42mp - 2gb - 30mp

Where has THIS been all my (picture taking) life?

So I’ve been using StarStax most of my star trail taking years. I happen to be in Ireland, next door to the most amazing ruins of a Franciscan Friary. The clouds actually went away, rare for Ireland, so I grabbed my camera and set it up for a couple hours to shoot star trails, thinking I’d have to wait to get home to stack them all together. Then I saw this app, and it’s AWESOME! Love the JPEG and MOV options and I’ve been playing around with different sets of images for the past few days. Way to go creating this app, and well worth the reasonable cost. Gone are the days I have to lug my laptop around to see the payoff of a long night of picture taking…thanks!

I’m an amateurish photographer self teaching myself Astrophotography. I took my first shot at star trails last night and spent all day trying to figure out how to stack my +440 images without crashing my computer. This app did it all AND keeps the file raw as well as provides either stitched together movie or individual photos for a nice time lapse. Wish I found this app sooner! Worth way more than $2.99 in my opinion!Great job creating a simple app that is easy to navigate, not complicated to understand and as a result that is incredibly easy to use!

Simple Program without much documentation

The program seems to have little to no documentation on use and or file formats it can work with. It stacked almost 300 jpegs, but gave me no options as to what I could do to improve the blend mode or appearance of the star trails. The program did stack the images, but Adobe Lightroom did most of the heavy lifting in prepping the images. I guessed that jpegs would work as it would not allow me to select raw files. I give it a 3 Star rating which is a C as it is about as basic as it gets in stacking and does not assist the user in getting more out of the program to achieve a archival finished image. I would only recommend this program for the hobbits who has low expectations and just wants to stack frames.

Simple to use and great results

I have been collecting Star-stacking apps for years. They are often complex, quirky and give mixed results. (They might give great results but I've never been able to figure out how to use them) Some have been around for years but don't run on Apple Silicon. Here's an app that's reasonably priced, gives great results and is easy to use. The bonus is that is runs on Apple Silicon Macs, iPads and iPhones. Great combination. I am very happy with this app. Well done.

* You can now import time lapse videos of stars moving through the night sky into the app to create a new star trail image or star trail video. * New design. I would be very grateful if you could leave a review/rating and if you have any feedback, please contact me via email which can be found on the Info page within the app.
