Stacking App Review - Finding The Best Stackers

Stacking App Review - Finding The Best Stackers

While astronomers have some good alternatives for stacking multiple exposures to reduce noise, the apps they use are generally expensive and complicated to use.  For these reasons, I tend to like using Photoshop to handle stacking my images.  Other options have been limited and hard to get excited about.  Over the past few years however, the quality of our options and my opinions of them have changed significantly.

Background
Wide-field astrophotographers have looked to Adobe Photoshop to handle their stacking needs for years.  It hasn't been a perfect fit but when combining 4 or so exposures to reduce noise, it's been an effective tool in reducing noise.  For those people who like to stack more than 4, staying with Photoshop pushes most people past the limits of their Photoshop skills.  And in looking at 3rd party alternatives, there simply haven't been good alternatives available since most of them are expensive and complicated to learn and use.
