Ol' Sol

1600 UTC: High noon, beautiful (though hot) Saturday afternoon, some fluffy clouds but skies otherwise bright blue, temp 76°F @ 1725 UTC, humidity 48%. Linda's off with the Ya Ya Sisterhood, just me, the scopes and the kitties...

C8 + TV85 set up on NE corner of deck. After north & level Quick Align I set out to align the TV rail once and for all. None of the hex wrenches in my possession are the correct size for the rear radius block bolts, but I suspect further tightening will help little. Finally got the sun centered in both scopes by extending front adjustment screws almost to their limit and using the washer under the front of the clamshell. I have no way of measuring the total of the gap + washer, but it is certainly more than could possibly be reached by tightening down the rear block - there just ain't that much space between the block and the C8 casting. But we're aligned, and I'm happy for now. I'm thinking a spacer to go between the front of the rail and the front block will be the most practical solution.

Several sunspot regions visible on the SOHO MDI @ 1600 UTC:



1930 UTC: Broke out the Neximage and took some shots of the sun with both scopes. Most of the TV85 shots were out of focus, C8 shots were even worse. The best shot shown here:
