I forgot to mention, NEVER point an SLR or dSLR towards the sun without a proper solar filter. Eye damage will occur. This shot was taken with a digital high-end point-and-shoot. No eye problems, but you can't keep the camera on the sun too long as it may damage the imaging sensor, even with a solar filter.

This was taken with camera only. The Finepix HS10 has 30x zoom with 35mm equivalents of 24mm to 720mm. This shot is just cropped from the 10Mpixel frame. each sunspot (or group) is numbered. There are actually 4 sunspots now, 1271, 1272, 1274 and 1275, but the other three are too small to see with my camera. Only takes about 10 days for them to seem to go across the face of sun since it rotates once every 25 earth days. This was also handheld. Tomorrow I'll use a tripod and several exposure settings. Maybe I'll get lucky and be able to see some of the others. Thanks for the encouragement and kind words.

Wow, this is a "camera" shot, not a telescope pic with attached camera - (right?) terrific.
(PS, that 1271 must be an official designation for this year's sunspots?)
