Acorn 6 was recently released, and it exposed a subtle bug in our Acorn Plugins that caused it to load the images with a reduced bit depth. With help of Acorn’s developer we have resolved the issue, and the updated plugins are now available.
The images loaded just fine on Acorn 5.6.5, but the update is also recommended for users of this version.
Acorn by Flying Meat Inc. is a powerful image editor for macOS that supports nondestructive levels, curves and filters, layer masks, batch editing and many tools that work on pixels, text and shapes. It supports images with 8, 16 and 32 bits per channel. And you don’t need a subscription. It is a cost-effective solution for post-processing astronomical images.
After installing the plugins, you can open FITS, XISF and SBIG images with Acorn as easy as a JPEG or TIFF. The plugins are free, but you do need Observatory and Acorn to use them. They are a great addition to Observatory’s Quick Look and Spotlight plugins for the same image formats.

It improves the background gradient handling of the plate solver and align adjustment. It also fixes the issue of stacks not being updated after selecting different picks. And we resolved a bug that we believe may have been the cause of thumbnails occasionally shifting down in the image strip browser on macOS Sierra. We have not been able to consistently reproduce this issue though, so if you still see it after this update, then please contact us.
