  1. Hi, Just wondered if anyone here picked up this 200mm SCT Celestron at today's auction in Leics. I thought it looked like it might have a bit of a dent (partially hidden by the lens hood!), but thought it might be worth a punt at £90 max. It eventually went for £150. Might be OK. Who knows?
  2. Hi. I can't stop myself reviewing all the images I captured of the eclipse. Here's a composite of Second and Third Contact. Canon 700d, 300mm lens, f/8, 1/1000 sec, ISO200. All controlled automatically by SETnC sotware, leaving me to enjoy the spectacle. Casper, Wyoming.
  3. Interesting. The two moons are between 100 and 300m across, so would presumably be bright enough for amateurs to capture, although they may be too close to the main body to separate them. FLorence has two moons
  4. A thread on another forum discussed the apparent vigorous activity of prominences during the eclipse, and that during the 2 minutes of totality they seemed to show obvious movement and become more prominent. This would clearly demonstrate phenomenal movement in a very short time. However, this little video of my own images shows that this was simply due to them becoming more uncovered as the larger moon's disc passed over the Sun. They didn't change. Just the amount of them that you could see. Canon 700d, Canon 70-300mm zoom at 300mm, 1/1000 sec, f/8, ISO200. Quite pleased with the result.
  5. Hi folks, this is a combination of captures with a Canon 700d at 200 ISO, Canon 70-300mm zoom at 300mm, between 1/4 second and 1/1000 at f/8. Look closely and you can see Regulus lower left. Never had the opportunity to image a total eclipse before, apart from the 1999 one in France, long before the days of digital!
  6. Diamond Ring, 21st August 2017

    Thanks, Reggie. I was on a ranch near Casper, Wyoming, away from all the crowds with only cows for company! My two sons and I had the location all to ourselves. Here's a fisheye view of us during totality. The hills in the background are the foothills of the Casper Range.
  7. Back home now, and going through my images of the eclipse. Here's one of the diamond ring at second contact. One of the most memorable sights visually. A bit of high cloud, but personally I quite like the effect. Canon 700d, 70-300mm zoom at 300mm, ISO 200, f/8, 1/1000 sec.
  8. Hi all. More eclipse images! This is an animation of the entire eclipse, captured with a Canon 700d and 70-300mm zoom at 300mm f/8, ISO 200 from Casper Wyoming at an altitude of 1,570 m. The partial phases were captured every 5 minutes at 1/2000 sec with a Baader filter. Totality was captured with a range of exposures from 1/4 second for the corona, and 1/1000 second for Bailey's Beads and the Diamond Ring. I saw the 1999 total eclipse in Northern France in superb conditions, but I don't remember it having the same emotional effect. Possibly because I had a screaming 6-month old baby in the car at the time. He accompanied me for this eclipse too, as a sullen 18 year-old!
  9. Here's a couple of animations I've prepared showing second and third contact. The diamond ring effects at each contact were noticeably different. Canon 700d, 300mm lens, 1/1000 sec, f/8 ISO200. Warning: Flashing images! Second contact: Third contact:
  10. Hi all. I've prepared this sequence of images showing the entire eclipse, captured with a Canon 700d and 70-300mm zoom at 300mm f/8, from Casper Wyoming at an altitude of 1,570 m. The partial phases were captured every 5 minutes at 1/2000 sec with a Baader filter. Totality was captured with a range of exposures from 1/4 second for the corona, and 1/1000 second for Bailey's Beads and the Diamond Ring. The captures were automated using the superb SETnC software, and the camera was tracked on a driven AZ mount, leaving me to enjoy the visual experience. And what an experience! The AZ mount resulted in field rotation, as can be seen in the position of the sunspots, but that didn't bother me. There was also some high cloud which appeared at the end. Click on the image and you should get a larger 6050 x 3300 image. The original image is vast!
  11. As the finale to our eclipse trip, I captured the 2-day old moon setting over the mountains behind our camp site at Estes Park, 8200 feet above sea level in Colorado. An unexpectedly photogenic moonset. I'm now done with camping for a few years! Canon 700d, 70-300mm zoom at 300mm, ISO200, f/7.1 1/10 sec.
  12. Hi folks, I set up my Canon 6D with an 8mm Samyang fisheye to take a movie of me and my two boys watching the eclipse from Casper, WY. Exposure was set to auto. As you can see, we had a great location all to ourselves. So much for the people-apocalypse which was predicted. Here's a couple of stills mid-eclipse and a minute outside totality. 2 minutes after totality Totality: Animation, 1 frame every 5 seconds. It might take a while to load:
  13. Awesome Wyoming eclipse

    There will, of course, be innumerable eclipse pictures around now, and here's my preliminary offering. We were at Casper, and the weather, software and hardware performed admirably. My military-style planning paid off! Lots more processing to do, but this is a very quick animation. The diamond ring, prominences and the corona were spectacular. Worth the $$$$$ that it cost to get here...probably. Canon 700d with 300mm lens, 1/1000s, ISO 200. More to come....
  14. Aug states Solar Eclipse

    Well, I've made it so far. Arrived in Denver on Tuesday night, then a whistle-stop tour through Nebraska and S. Dakota to visit Mt. Rushmore, Crazy Horse Monument and Devil's Tower. Now 100 miles from Casper WY, hopefully getting there tomorrow morning and sit out the weekend. Here's me and my boys testing the solar glasses (pukka ones from FLO) on the South Dakota border.
  15. Hi folks, For no other reason than idle curiosity, I thought I'd have a brief bash at deep sky imaging with my basic IMG132e planetary cam using Sharpcap's live stacking ability. The IMG is basically just a webcam with a 1/3 inch CMOS sensor with 1280 x 1024 pixels. I was quite surprised at the results with just short exposures (4 seconds). Looking at M57, a single 4 second exposure was very noisy but the mag 15.3 central star was clearly visible, with a hint of the nearby 16.3 mag star. With increasing stacking and exposures, the image becomes less noisy and fainter stars become much clearer. Anyway, here's a few captures from the session. Albireo always looks awesome! IMG132e cam, 250mm f/4.8 Newtonian. In my youth, capturing a mag 15 star with just 4s exposures was sheer fantasy! Hardly prize-winning stuff but, as a relative old-timer, I'm just amazed at what is achievable with relatively basic kit. M57 closeup with various stacks M57 full frame: Albireo, 29 x 2s M2, 33 x 4s
