so let me get this straight - you are still sticking the camera to the PST. Does it move at all? I might try redoing some solar work using Velcro with the PST – what do you think?
John, I'm using a Tak FS-60C with a Coronado SM40 + BF30 + DMK51.
I do have a Coronado SM90 (Solarmax II) Double Stack using external Etalons on a Williams Optics 102ED refractor and will soon get an adapter to use the FS-102 scope. I have a lot of trees in the way and imaging the sun in the winter is difficult so I tend to use the FS-60C as I can move it around the property easier.
Here is my image taken with the FS-60C + SM40 + BF30 + DMK51, it was taken at the same day as your image (23/06/2013) at 11:17am NZST. Your image would have been taken much later when there was an increase in prominence activity.
I took 2400 frames and used the best 600. The seeing was not the best as we have had stormy weather for about 4 days. The sun was about 28 degrees above the horizon so it was quite low, my latitude is -40.5 degrees.
Seeing, & your low Sun elevation isn't helping George. Here in Bundaberg QLD it's just on 42 degrees at it's highest point. I start at 10AM if I can, making the Sun 35 degrees above the horizon at that hour, so it's mainly about that seeing at anything below 45 degrees.
I agree, my low Sun elevation does not help, that is why I have currently been using the SM40 Etalon rather than the double stacked SM90s, plus I have the neighbors trees near the sun's highest elevation which shades my backyard.
Pretty tight so no, it doesn't move. Velcro would be ok.
