Solar Imaging on a Winter's Sunday afternoon
23 February 2014
23 February 2014
Rare is the day when I get a sunny day and the opportunity for some Solar imaging. This Sunday afternoon on the 23rd of February came together nicely and I set up the C102mm Refractor on the CG-5 for some white light and H-Alpha imaging.
But, as the Sun climbs higher after the winter Solstice, my trees are interfering with decent angles...

Great in the summer, providing a shady cool canopy, but I must decide if I will keep them or cut the obstructions down.... 
Despite the obstructions, the solar disk was sharing some pretty decent Sunspot activity...

Starting off with just the Full aperture White Light Objective solar filter at prime focus and the Canon T5i, the Sun shows off it's colorless face. But, popping on a stacked Yellow/Light Pollution filters brings out some more detail...
Atmospheric conditions were not ideal this day, but AR 1981/1982 were stage center - with AR 1987 swinging around.
Even with the damned branches in the way, some decent grabs - this time Afocal with the Zhumell Zoom 1.25 eyepiece adapted to the Canon T5i T-mount...
Pushing magnification was not as profitable as wide fields were this day.
Removing the C102 and sliding on the Adler's H-Alpha 40mm Solar Scope...we catch minor prominences along the limb...
Decent Faculae and filament display, but images are not sharp this day. Winds, high clouds, trees and turbulence... all conspire against good imaging for this session.
