Thursdays Solar Feast With Lunt LS100THa / Stellarvue SV80s /ES AR152 + Lunt CaK filter or Baader Wedge Uploaded 10/24/14 Solar Observing Report For October 23, 2014
Images below are 1290 wide and non clickable
Here we have the combination of the largest sunspot in this current weak solar cycle, and a partial solar eclipse. I set up in the morning to image the spot, and later in the day on the balcony for the eclipse.
WHITE LIGHT:
Taken with the Explore Scientific AR152 (six inch) refractor, Baader Herschel Wedge, and Continuum + IR/UV block filters. Taken in the morning before the eclipse started
to highlight the huge sunspot, AR2192.
Prime focus - You can see the large spot already has somelight bridges across the umbra, a sign that its break up is in progress.
Here is a 2 part panorama showing the detail of the giant sunspot, using the 5x Barlow to zoom in with over 5 meters focal length:
Now a few more sunspots around the disk, all of these are much smaller!
Next we shot some Calcium K images with the same instrument. For this, we have a special Lunt filter which isolates this narrow ultraviolet wavelength.
The details around the spots in calcium light are astounding:
Finally, we go with the Hydrogen Alpha wavelengths, using the Lunt 4 inch also piggybacked on the 12 inch tube. Here is the full disk, note also the huge filament on the left side:
Now for some 3x Klee Barlow views:
Here is a shot in the red wing of Halpha to show the bright points called Ellermann Bombs. To do this, we de tune the Lunt off Halpha about 3/4 of an Angstrom:
Setting up at 2:30pm for the partial solar eclipse on the balcony on the back of the house:
T'Pring does some eclipse observations:
At 3:38 the maximum was 44% and I took this pair, the first one is white light with the SV80, and the second one is in Calcium K:
Thats it for today!
