Here are some member pictures of the August 21,
2017, Solar Eclipse...
Members who have a photo of the eclipse may submit it to the for inclusion here.
Steve Mattan captured the image of the eclipse on the left at 17:21:26 UT (10:21 am PDT), the middle of totality, from the Bandit Springs trailhead outside Prineville, Oregon. He used a Canon 60D digital SLR camera and a Canon 100-400 mm f4.5-5.6L USM zoom lens, set to 400 mm focal length, on an AstroTrac TT320X-AG equatorial mount. It was exposed 1/4 second at f/8, ISO 100. The image on the right has enhanced brightness and shows reddish tinges from prominences on the western (upper) limb, extended detail in the corona, and if you look closely, lunar surface features illuminated by earthshine.
Arnie Rosemoff captured this wide-field image of the totally-eclipsed sun with his Apple iPhone 6s from Prineville, Oregon. The previous morning, Sunday August 20, he also captured the Old Moon (about 30 hours before new) as it closed-in on the sun for the eclipse.
John Ambrose observed the totally-eclipsed sun from Santee Lakes Campground in South Carolina, and captured images with a Canon Rebel 60Da digital SLR camera and a 70 to 300 mm zoom lens, set to 300 focal length, tracking on an iOptron mount. The upper image above was taken at the end of totality as the reddish chromosphere was reappearing. Exposed 1/200 second at f/5.6, ISO 2000. The lower image was taken just after the end of totality as a thin sliver of sunlight reappeared. Exposed with a full-aperture solar filter, 1/400 second at f/6.3, ISO 2000. More of John's eclipse pictures here.
Jim Mack observed the totally-eclipsed sun from the centerline in Bolton, South Carolina. The images above were taken with a Canon Rebel T2i digital SLR camera and a William Optics 80 mm f/6.9 refractor tracking on a Celestron CG5GT German equatorial mount. The upper image showing the Corona during totality (and Regulus in the upper-left corner) was exposed 1/100 second at ISO 1600. The lower image with the Diamond Ring at the end of totality was exposed 1/1600 second at ISO 1600.
WAS President Roger Cowley captured this creative image during the partial phase of the eclipse, using the "spaghetti strainer" method (i.e., pinhole projection en masse) to spell out WAS 50 in honor of the club's upcoming anniversary. Roger was in Glendo, Wyoming, to observe totality with a Sky & Telescope tour.
Steven Kutoroff captured this image of the partially-eclipsed sun at 2:25 pm EDT from Cherry Hill, NJ, catching a gap in the clouds that engulfed the WAS home area by mid-eclipse at 2:45 pm. Taken with a Sony A6000 mirrorless digital camera through a Questar telescope equipped with a full-aperture solar filter (estimated ND4.5). Exposed 1/1000 second at ISO 100.
Russell King captured the "Diamond Ring" an instant before the start of totality (upper image) and then totality itself (the lower image) from Belton, South Carolina, where mid-eclipse was at 2:43 pm EDT. For both pictures, he used a Canon Rebel T2i digital SLR camera and a lens at 220 mm focal length. Both exposed 1/60 second at f/8, ISO 800.

Howard Schneck captured this series of images from Santee National Wildlife Refuge in South Carolina during the partial phases at the times indicated (maximum eclipse, and the middle of 2½ minutes of totality, was about 2:43 pm EDT). He used a Celestron Edge 800 and a Sony NEX-5 digital camera. He did not take any stills during totality (although he does have video). He was busy using the brief period of totality to observe the eclipsed sun (e.g., the Diamond Ring and the Corona) and the darkened sky around it with the planets Venus, Jupiter and Mars.
