||11 September 2005
||This sunspot alone is responsible for
making September 2005 the most active solar month since
1981. There were 9 X-class flares from this sunspot and
some of them caused Northern Lights here. Picture taken
with Canon 20Da through Barlow Bob's wonderful H-Alpha
||Shot taken through the
Bob-O-Scope in our backyard. This is a stack of 6 images
from the Canon 20Da with a 4x Powermate. Multiple
images stacked to reduce the effect of Newtons Rings (a
problem with the Canon 20Da taking pictures in H-Alpha).
Images combined and sharpened in ImagesPlus. Color set
and dust on sensor removed in PhotoshopCS.
