    ~ Unusual Circular Filament & Solar Flare ~ On the 13th November 2015 there was this unusual circular shaped filament on the surface of the Sun that’s nearly the same size as the Moons orbit around the Earth! While taking the images an area began to flare just to the east of this huge filament, which was very exciting. The flaring began at about 11.25am (AEST) and was still very active by midday when clouds came and covered the whole sky…and that was the end of that, no more pictures! The H-alpha images were taken with the clubs Lunt 80mm solar telescope and a Canon 700D camera with a 2x Barlow lens attached, there where 25 images stacked in RegiStack6 and processed in PS CS4. The monochrome image is with the same camera using the monochrome setting.

  • Sun 8th Aug15 NLowndes.jpg

    This huge sunspot group named AR2396 is over 150,000kms in diameter and the dark core is now three times the size of our Earth, image was taken on the 8th August 2015. The image was taken with a Meade 80mm refractor telescope fitted with an Orion glass solar filter. I used a Canon 700D camera with a 2x and 3x Barlow lens attached, the exposure time was 1/640th second and ISO 200. There were 25 images stacked in RegiStak6 and then processed in PS CS4.

  • SunBW NLowndes.jpg

    Hydrogen Alpha image of the solar surface taken on the 8th August 2015…you can see so much more detail on the surface of the Sun in H-alpha. In this image you can see prominences on the limb, dark filaments on the surface and the active region around the huge sunspot AR2396. Image taken with the clubs Lunt 80mm solar telescope and a Canon 700D camera with a 2x Barlow lens attached using the monochrome setting in the camera. 25 images were stacked in Registack6 and processed in PS CS4.

  • Halpha Sun NLowndes.jpg

    Hydrogen Alpha colour image of the solar surface taken with the clubs Lunt 80mm solar telescope on the 8th August 2015 and using a Canon 700D camera fitted with a 2x Barlow lens. This is a composite image, you need to take two sets of images one set for the solar disc and another set for the faint prominences that require a longer exposure to capture the ejected plasma, images were then combined in PS CS4.
