Solar Imaging on a Sunday Morning
21 April 2013
This day was warmer than yesterday, but still chilly. Setting up the Celestron 102mm Refractor with full aperture Baader solar filter, we follow along with Sunspot group #1726 as it heads toward the solar limb...
Visually, I was observing fine details in the cluster, but it just doesn't translate when I image. Better imaging equipment is in order....
But, watching the lower left of this sunspot group throughout this session, I could swear I was witnessing movement of the magnetic fields...
Not anything dramatic, but subtle changes over time.
It was still a bit windy this day, and scope shake was a factor, but we try to muddle through...
I think that I'll try to video the next session and stack 'em. I have never done this before, but many others have achieved great success in sharp details.
Before I packed things away, I brought out the Binoviwers...
Stereoscopic views of #1726 were incredible. This was the first time using the Binoviewers with the new Dual Focus Crayford style focuser and I wasn't too sure if they would work in reaching focus. (I had a problem with them with the old stock focuser on the 102mm.) But, they came to a nice focus quite easily and with the mini-barlow that screws into the viewers.
So ends this solar session.
