I observed the mammoth sunspot AR 10365 late Wednesday afternoon and again early Thursday afternoon using the Astronomical Society of Harrisburg's C8 at 78x and my C4.5 at 53 and 72x respectively. This is certainly a very large sunspot and is easily visible without magnification. Three smaller spots were also noted.
