The Total Lunar Eclipse of 28th September 2015

Pete Hill assembled this animation of the eclipse of 28th September 2015 from images he took using a Canon 450D camera with a Sigma 150-500mm zoom lens. He used a 500mm setting, and various ISO settings and exposures as conditions changed. The images were processed in Photoshop CS6 and animated using animation shop in Paint shop Pro 5.  Image Copyright: Peter Hill.

This collection of images was taken during the early hours of the morning of September 28th 2015 by Peter Branson. Each image is a single exposure. Peter comments: 'While any part of the Moon was illuminated the exposures had to be kept short - 0.001 s - 0.01 s. Only when the Moon was in shadow could the exposure be increased and then only to 2 - 5 s. Visually the change in colour/hue was not hugely significant at total eclipse. The colour change was not as great as shown in the images as no proper colour (RGB) balance has been applied in any of them. That's why the rust coloured ones are so much different and so much more spectacular that the rest.' The photos were taken with an ATIK 314L+ CCD camera attached to a TS Photoline ED102 refractor telescope with field-flattener and Hutech IDAS light pollution filter attached. The setup was mounted on an HEQ5 equatorial mount set to lunar tracking. The single image below the sequence is of the full lunar eclipse and was produced from eight 3 second exposures. The images were first converted from FIT files to TIFF files and then stacked in Registax. Colour was enhanced using the stretch function and then wavelets were used to sharpen the final image.  Image Copyright: Peter Branson.

Chris Newsome took this image of the total lunar eclipse of the 28th September 2015 using a Canon 40D DSLR piggy backed on a Skywatcher 102D telescope on an AS-GT mount. The image is a single frame at 400 ASA using a 300 mm lens.  Image Copyright: Chris Newsome.

The following four images were shot by Robert Seymour from the Belper dark sky site of the East Midlands Stargazers during the early hours of the 28th September 2015. Robert used a Sony A7S camera directly coupled to his William Optics 132mm f/7 APO refractor. Only an unpowered alt-az mount was used and no filters. Only a bare minimum amount of post processing was done to the images using Mac OSX Photos. Robert comments: "The A7S has 'focus peaking' in manual mode which is invaluable and makes imaging easy. Simply a matter of selecting the right exposure length, usually between 2 seconds and 1/500 second, and matching it with the correct ISO setting for that particular scene. The A7S also has amazing low light sensitivity. Really pleased with the camera".  Image Copyright: Robert Seymour.

Taken at 02:15 (8 minutes into the umbral phase). 1/500 second exposure at ISO 100.

Taken at 02:31 (24 minutes into the eclipse). 1/60 second exposure at ISO 100 using a 2x Powermate on the scope.

Taken at 03:09 hrs (62 minutes into the eclipse and only 2 mins before totality). 0.8 second exposure at ISO 200.

Taken during totality at 03:38 hrs. That's 91 minutes into the eclipse and 27 minutes into the total phase which itself was 9 minutes away from maximum.
1/3 second expousre at ISO 6400. "It was nice to see the stars pop into view during totality".

Although not taken during the eclipse itself this photo of the 'super moon' of a few hours before was taken by Dave Maynard on the 27th September 2015, and includes the silhouette of an aircraft with contrail. Dave used a Nikon D5000 DSLR camera with a Tamron 70-300 mm lens, an aperture of F/16 and a shutter speed of 1/200 s at ISO 200.  Image Copyright: Dave Maynard.
