Equipment Details:

Coronado SolarMax 90 Ha telescope, ZWO ASI178mm video camera.

Post-processing Details:

The image is a 5 piece mosaic. I took five 30 second videos using SharpCap and stacked 300 frames from each one using Autostakkert, then sharpened the images with Registax Wavelets, then processed and stitched the images with Photoshop.

The image shows active region 3471, some nice filaments, and some decent prominence.
