  1. I had it printed on a 30"x20" poster (using Photobox). Prints very well. May look for a more specialised printer where I can imbed the printer profile and see how it improves.
  2. Taken at the 21st August Solar Eclipse at Menan Buttes, Idaho. A composite of 15 frames. Five were of the first partial phase, taken from just after first contact until just before second contact. A filter made of Baader Solar film was used and exposures were 1/400s. Five are during totality, various exposures to reveal Baily's beads at 2nd Contact, prominences, Inner Corona, Chromosphere, and 3rd Contact Diamond Ring. The second partial phase was taken in the same way and exposure as the first partial phase. The colour cast of the Baader film was corrected by an adjustment layer in Photoshop.

  4. Here's a sequence of 10 shots showing the development of Baily's beads at second contact over a 4 second period during the 21st August Total Eclipse. Taken at the Menan Buttes, Idaho with a Canon 70D, Canon 100-400mm Mk2 lens and 1.4x extender. ISO 200, f/8. Baily's Beads from start to finish by James West, on Flickr
  5. That was very much a "try it and see" whilst I concentrated on the closeups. Just let the 5DMk3 trigger every 5 mins, ensuring I got a bright image during totality, and stacked with StarStax. Pity there is a lack of foreground interest, but very effective.
  6. Some shots from the Total Eclipse on 21st August 2017 taken from Menan Buttes, Idaho. More on my blog here: https://ejwwest.wordpress.com/2017/08/21/2017-total-solar-eclipse/ and on Flickr:
  7. Taken at 0218 am on 14th July 2017. ISS transit of the Moon. The ISS had just come out of shadow, was low in the sky: ISS Lunar Transit by James West, on Flickr
  8. I used my Canon 5D Mk3 to create this - the wider field from a full frame sensor captures more than my cropped frame 70D. It's 125 30" exposures at 3200 ISO stacked in Deepskystacker. The 5D Mk3 can handle 3200 ISO much better though I used Lightroom to denoise it somewhat. M42 - Great Orion Nebula by James West, on Flickr
  9. Yes. Took years to find the right technique. For the Sun and Moon shots where the ISS isn't visible I use a GPS to get the accurate time and start a burst of shots about 1 second before the predicted transit and stop about 1 sec after the transit. This usually means I have to shoot in JPEG, not RAW, as the camera buffer isn't big enough to hold more than about 7 shots in RAW.
  10. I regularly check Calsky to see when transits of the Sun and Moon occur and if one is reasonably nearby try to photograph them. I knew this one was occurring on the morning of 18th Nov so got up early, saw the sky was clear, and drove to a site close to the centreline (a car park at the University of Southampton in this case, but Calsky provides the path so you can find a convenient location). General technique is described here: https://ejwwest.wordpress.com/imaging-the-international-space-station/ Had the path been visible from my back garden I'd have set up my telescope (2350mm focal length), but having to drive I used my 100-400mm Canon zoom lens with 2x extender giving me 800mm focal length so not as much detail as this: Just Passing Through! by James West, on Flickr

  13. Managed to have a go at producing this: Lunar Eclipse 2015 - composite by James West, on Flickr
  14. Some more details posted on here: https://ejwwest.wordpress.com/2015/09/28/total-lunar-eclipse-september-28th-2015/ I need to create a composite image. I may try tonight but suspect i won't be able to stay awake.
  15. Here are some photographs taken during the total lunar eclipse on the morning of 28th September 2015. All photographs were taken from my garden in Chandlers Ford Hampshire. This was the so called "Supermoon" eclipse. All photos taken with a Canon 70D with Canon's 100-400m IS (Mk 1) Zoom lens and 2x extender (800mm efective focal length at f/11). The Partial phase was mainly at ISO 200 and exposures of 1/200 to 1/50s. The total phase (and the "red" effect on partial phase) needed exposures of more than 1 second and/or high ISO. I took various shots between 1s and 10s and ISO of 800 to 6400 with the 70D long exposure noise reduction and high ISO noise reduction turned on. The camera was mounted on my Celestron EdgeHD 925 telescope tracking at Lunar rate. Unfortunately vibrations of the mount meant many shots had "judder" and were rejected. Whilst the media has focused on this being the last "Supermoon" eclipse before 2033, there will be Lunar Eclipses visible in the UK before then.

  16. If you have a camera with LiveView or equivalent, where you can use the LCD panel instead of the viewfinder, then you can centre a bright star in the centre, if necessary at a high ISO, and zoom in on it with digital zoom. Then use the manual focus ring until the star is as small and sharp as you can make it. At the moment Vega and Altair should be bright enough to focus on first. Sent from my iPad using Tapatalk
  17. The Canon 10-22mm lens has a large depth of field so doesn't need to be accurately focused and can be set on infinity using the focus ring and hoping for the best! In this case, I could focus on the arch whilst still light and then put on manual focus. Sent from my iPad using Tapatalk
  18. Poole and Bournemouth are to the east and this is facing south. The tip of Portland bill is to the right and some of the lights are ships in the Channel. The orange glow on the horizon may be from Cherbourg or other parts of Northern France, but I may be wrong. Sent from my iPad using Tapatalk
  19. It's the Canon 10-22mm EF-S lens. I tried using my flashgun to brighten the arch but with limited effect due to its distance. I used Lightroom's Magic brush to lighten it instead, but need to be careful of overuse. This photo (the unenhanced version) was shown on ITV Meridian Weather last night.

  20. Top one is ISO 3200 and bottom one 1600. At 3200 there is quite a bit of noise which I reduced somewhat in Lightroom. Aperture us f3.5 and exposure of a minute for the bottom one and 30s for the top one. Sent from my iPad using Tapatalk
  21. Taken on Sunday evening with Canon 70D and 10mm focal length: Milky Way over Durdle Door by James West, on Flickr The Milky Way over Durdle Door by James West, on Flickr
  22. Another Solar transit (they're more frequent than you might imagine) but due to the weather didn't want to leave my scope outside. The clouds cleared enough in time to set up my 400mm lens with 2x extender and the Thousand Oaks filter. Getting it focused is the biggest challenge but so is the exposure. I had to process quite a bit in Lightroom and then PSE12 to align and stack. ISS Transiting the Sum by James West, on Flickr
  23. Started the sequence just a tad too late to get the whole pass. Lots of haze and despite focusing sharply the night before, I guess the temperature change by the morning defocused the scope slightly. ISS Transiting the Sun by James West, on Flickr
  24. Taken with Canon 70D and 800mm Lens (100-400mm zoom plus 2x extender): Sun with sunspot AR2331 by ejwwest, on Flickr
