    These are some of the first images that I have taken with the Canon 650D.

    This is currently a work in progress. Playing around with Photoshop CC to try and extract more detail from this image. This image is not as cropped as the others I have posted.

  8. Superb image. Crisp details. Was just staring at this image for 5 minutes. GW
  9. Great image. What focal lengths are you using?
  10. Stunning image. I'm becoming a big fan of Ha.
  11. Failing that, as Mr Spock once said "Its life Jim, but not as we know it"
  12. That's very interesting Magnus. The structures you mention may be again, small segments of the cornea that break up in the eye and come in an out of focus. Also in bright light you get reflective effects taking place. These pieces of cornea have random structure and move around rapidly on the surface of the eye. You can test this out easily. On a bright afternoon, cloase your eyes and then focus on the inner of your eyelids, you'll see the cornea floaters and the white specks of light as well. GW
  13. Hi, Are thease pin point flashes of light. If so they are probably acutally caused by your eye. The phenomena basically takes place on your retina when you look at bright objects. The following article may be of use. https://www.aao.org/eye-health/symptoms/flashes-of-light Best GW

    This is my first attempt at Hydrogen Alpha. The image processing has been done in photoshop and is very basic. There are vertical bands in the image which I am not too sure how to get rid off. Any suggestions on image processing H-Alpha images would be greatly appreciated. No calibration frames were used. The image was taken with a Canon 650D and 100mm Samyang Lens at f3

  19. Like the images you are producing. The detail in them is fantastic. The colour schemes you are using add a surreal feel to the images which is great. How are you getting good focus on the HA filters. I am just starting out and have just got an Astronomik 12nm Clip filter. Do you focus fist without the filter and then clip the filter in place. Any advice would be greatly appreciated. GW
