Giant Sunspot October 25th

A giant sunspot has been making its way across the face of the sun for the past few days. If you have a solar filter or hydrogen alpha scope, check it out before it sets behind the sun's limb early in the week.

Here are two images taken the morning of 10/25 with a Stellarvue 80mm f/6 achromatic refractor on an iOptron Minitower with a Baader mylar filter. I used a Celestron Skyris 445 monochrome camera. The full-disk image used a 0.5x focal reducer, while the detailed image was taken with a 2x Barlow. I used an Astromik 12 nm hydrogen alpha filter in front of the camera to boost contrast and sharpness. Best 20% of ~5000 1280x960 frames @ 30fps, stacked with AutoStakkert!2, wavelets with Registax 6 and final cropping and contrast balance in Photoshop Elements.
