White Light:
Lets start with a full disk shot from the start. We have one large sunspot AR1384 that is leaving us on the western limb to the right, and a fantastic smaller group of four coming onto the disk on the lower left including the largest AR1389. This is with Baader Astro Solar Safety film over the aperture of the 80mm f/6. The speckled pattern all over the disk is solar granulation.
Now for some close ups with the 5x Televue powermate. Seeing was average, so there is some granulation visible here. This is the former large sunspot AR1384 seen approaching gthe limb. Notice that it is starting to fragment, as evidenced by the light bridge in the umbra.
Just coming onto the limb is four gorgeous sunspots amidst a sea of faculae. The largest is AR1389, with AR1388 to its lower right.
Near the very center of the disk is a small group AR1386. You can see plenty of pore action around this one!
Hydrogen Alpha:
Next we will examine the full disk in Hydrogen Alpha Light. This is with the Lunt LS100, and the Antares .5x Focal reducer. There are only a few prominences on the Sun today:
Now for some close ups with the Televue 2.5x powermate. Here is our departing friend, AR1384. You can still see the light bridge in Halpha.
II thought Id try some negative images too for viewing a more 3d look:
Next, here is our foursome of spots coming on to the limb in both positive and negative views, again the 2.5x powermate.
Near the center of the disk is AR1386 in both positive and negative:
Finally, even though the seeing was only 2/5, it had its good moments. I tried the 5x power mate for fun. A bit much, but here is a positive and negative.
