What’s New in Version 1.3

2025-03-06

🌟 New multi-edit mode

You can now perform actions on multiple scans in a single operation. For example, deleting multiple scans at once. There are two ways to access this feature: either by long-pressing on a scan or using the scroll wheel button at the top right of the screen.

🎞️ Create GIF animations

With the multi-edit mode, you can generate GIF animations from your solar images. A new way to share your observations!

➕ Stack your images for better results

Stacking is now available: combine multiple images to improve the signal-to-noise ratio and reduce atmospheric turbulence effects. More than just addition, SUNSCAN integrates an advanced algorithm that simultaneously corrects local distortions in H-alpha or other images and automatically applies them to the continuum image!

🔍 New zoom/pan system

A smoother zoom and pan system is now available, offering a better user experience, especially on iOS.

🌞 Improved artificial eclipse

For better visualization of solar prominences, we have added:

• Anti-aliasing for a smoother black mask.

• A new Doppler eclipse feature.

🏷️ Scan tagging system

At the end of a solar scan, you can specify the observed wavelength. This allows for correct image coloring during post-processing.

🪐 Helium processing

If you scan the helium line near the sodium doublet and your scan is properly tagged, a dedicated processing step is applied to generate an optimal image. This processing is also available in the advanced processing panel.

💧 Optional SUNSCAN watermark

An option in the settings allows you to add a watermark with the SUNSCAN logo, the observer's name (if provided), the scan time, and information about the observed wavelength.

📏 FWHM calculation tool

A new FWHM calculation tool has been integrated to facilitate SUNSCAN’s zero-order tuning.

🖥️ New Version of the Sunscan.local application

The application used to retrieve your data on your computer has been completely redesigned. It now allows you to:

• View stacking files

• View animation files

• Perform multiple folder selections for download or deletion

• Do the same for stacking and animations

• Zoom in/out on image thumbnails within a scan folder

• Display storage values (remaining/total space)

• Enhance image viewing with basic controls (zoom, rotation)

• Implement some minor design optimizations
