After a total cloud out last night following a cloudless day, the morning yeilded a few blue clearings in which I could shoot the Sun this morning. Solar activity is very low right now, but this could change soon.
WHITE LIGHT:
Lets start with the Full disk, with the 80mm at prime focus, Baader Wedge and Baader Continuum filter with IR block:
There are a few spots at this time despite the nearing of Solar Maximum, however the small regions are very detailed!
We next move in with the 5x barlow. The granulation at 80mm aperture is starting to show up clearly:
Here is a composite of two images that spans both spot groups:
With a scan of the Suns primary features in white light complete, we now move to the Hydrogen Alpha views with the Lunt LS100 and DMK51 camera.
The full disk is seen here, taken with the .5x Antares focal reducer to fit the full disk on the chip:
Increasing the exposure time and gamma to 150 yeilds a view of the prominences all around the limb. Ive blocked off the Sun in black because it is so bright it hides the ring features:
Now putting in the 3x barlow, we can now close in the individual features! Here is a filament leaving the visible disk and rotating off:
The big filament nearly centered on the disk.
Active region shaped like a bar magnet:
Both major active regions, many filamets are coming onto the disk:
This filament is coming onto the disk on the east side:
Next we increase the exposure and gamma to reveal the prominences on the limb:
Finally, two images taken in the "Wings of Halpha". Here I offset the tuner into the red wing to show off the bright spots around the active regions known as Ellerman Bombs:
Compare to this shot, taken in the Blue Wing:
Well, thats it for this weekend! Maybe some Perseids tonight...
