I set up my little solar rig, a PST and 50mm f/9 home-made refractor tandem on an old EQ-2 mount. I didn't bother with the double stack on the PST. The high cirrus haze robbed my photos of contrast, but it wasn't so thick that pics were impossible. Did anyone else notice that first contact was visible in H-a a minute or two before it was visible in white light? The solar disk is slightly larger in H-a because we are viewing the solar "atmosphere" at a higher level than in white light. I noticed this during the Venus transit as well. Here's a cell-phone pic. I didn't bother with the DSLR due to the cloud cover. http://i260.photobucket.com/albums/ii24/JethroTull1958/001a_zps8742359c.jpg Here's a pic of the rig I used. http://i260.photobucket.com/albums/ii24/JethroTull1958/003a_zpsee9c5b0c.jpg I haven't processed any H-a images yet. They really take a beating from cloud cover so the white light pics are actually better, IMO. On Fri, Oct 24, 2014 at 4:12 AM, Dave Gary <davegary@me.com> wrote:
Thanks, Joe. Yeah, that sunspot group was the only way I could maintain focus with the setup I was using. The camera’s viewing screen is so small it’s hard to see any detail for focusing. I don’t use “ auto” mode because the stock algorithm in “auto” mode tends to overexpose on solar shots. I switch the camera to shutter mode and focus myself. Most of the time I use a computer to look at a larger image of what the camera is photographing and focusing is a lot easier. However, I didn’t have time to hook the computer up this go around. I think if it wasn’t for those sunspots my focus would have been much worse. That grouping was huge. I think it’s the largest group of sunspots I have ever seen.

Very nice, Dave. I saw it through the clouds for a few minutes using
solar glassrd and that sunspot cluster was so huge that I actually saw it without magnification. I could barely believe its size and thought for a moment that maybe an especially dense clump of clouds had got in the way.

Here’s some quick and dirty photos of the partial eclipse from the driveway observatory in St. George. Pretty cloudy. In the last couple of photos the roof line of my house is obscuring Sun. Roof line is at top of photo. The telescope reversed up and down and right and left, I believe. Obviously, it reversed up and down. I was too lazy to edit the orientation in iPhoto. Such is life. I think the clouds add a nice touch. I started a little late into the eclipse and my roof obscured the final minutes. I caught totality for my location, though.
