Partial Solar Eclipse

Posted: 23 October 2014

Opened: Thursday, 23 October 2014, 1331 MST
Temperature: 100°F
Session: 732
Conditions: Clear with a few clouds low in north

Mounted the Orion full-aperture solar filter and the PST piggyback on the 8" LX200-ACF. 1341 MST: viewed the sun using my naked eyes with solar glasses. Sunspot AR2192 easily seen. Then viewed the sun in the 8" telescope at 83X. AR2192 very impressive looking. In the Hydrogen-Alpha PST at 27X there were no large prominences visible but some filaments and small prominences were seen.

This 300mm telephoto lens with a solar filter full-frame photograph using the D7000 DSLR, 1/1250sec, ISO 400, clearly shows sunspot AR2192:


I imaged the Partial Solar Eclipse using the Nikon D7000 DSLR, 1/1000sec, ISO 200, on the 8" at prime focus + focal reducer. 1426 MST: first contact as observed in the DSLR viewfinder. I took images every 10 minutes once the eclipse started. Mouseover or tap on the image below taken near mid-eclipse to see a video of the entire eclipse. Be patient while the 1.4 MB file loads.

I also imaged the sun through the PST in H-Alpha with the iPhone 5s using the modified MX-1 Afocal Adapter at 27X. Here are two images taken near mid-eclipse, both desaturated to bring out details on the sun including promineces and filaments:



1600 MST: final look at the eclipsed sun through the PST, 32X. 1646 MST: last contact visible in the DSLR viewfinder.
