  1. 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.

  2. 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.

  3. Hi Red Dwarf,

    I just got hold of a second hand Samyang 100mm 2.8 ED and its fabulous. The image quality is far superior to the 55-200mm Canon kit lens that I have. I just start astro-imaging and so far only using a Canon 650D and the above lens is getting me good results. I am not even close to describing myself as a novice, and am not an expert in image processing, but the image of the nebulae in Cygnus was the first result i got with the new Samyang Lens.

  4. To answer your original question nebula, the following link will take you to an image I took with a Canon DSLR 650 with a 55-250mm Kit Lens. 

    I only started 3 weeks ago and although the images are not great, lots of noise and hot pixels together with some star trailing thrown in, there is a certain ‘wow’ factor when you see these images processed in deep sky stacker for the first time.

    Hope these help you get an idea of what you can get with a very simple set up.

    The photos above were taken without light pollution filters, in a Bortle 8 zone, with a moon somewhere to the right. You can see my astronomy terminology is spot on :)
