This is my first solar image with the GTX and also first light with Baader white light Herschel Safety Wedge. I used my guide cam for acquisition, the ASI 174mm-cool (uncooled) Visually I didn't have enough magnification with only an 8mm eyepiece and a 2x barlow, but moments of good seeing allowed some fine details to be resolved in the faculae. Photographically with live viewing on my laptop, the details were amazing albeit the Sun's surface was pretty calm. This is at only at f12 and about 1600 mm focal length.
