Equipment Details:

Photo taken at 12.24 pm (= 06.24 UT), from Kostanay city in Kasakhstan. Since a few months I live here, and not in my homecountry Germany.
I used a Skywatcher Maksutov 127/1500, Baader solar filter, UV-IR cut filter, ALCCD 5-IIc. Mount was only an older EQ3, and manual tracked (unfortunately I don't have a motor tracker here).
4400 frames in AVI, resolution 800x600. Pre- processing with PIPP.

Post-processing Details:

Stacking with AutoStakkert3!, image editing with Giotto and IrfanView.

Image Details:

Active region AR 3105 on 20th September, 06.24 UT, from Koatanay/ Kazakhstan. Especially the faculae seem to be rather sharp in the image, nevertheless they are located near the solar edge.
Image taken with simple astronomical equipment (as I had to bring it from Germany to Kazakhstan as normal baggage in airplane): Skywatcher MAK 127/1500, Baader astro solar filter, older EQ3 (manualle tracked), ALCCD 5-IIc. But, nevertheless, with this "minimalistic" equipment, it is possible to get not so bad images of the sun in whitelight.
