I have been digging out old images and re-editing them. This image was captured via Observing with NASA – a public education site in which one can send schedules to robotic telescopes in Arizona and obtain selected images via email. This is a project in collaboration with Harvard University and is part of the MicroObservatory Robotic Observatory Network. This is used in primary education. I have used it in the past.
Here is an old image of the Crab Nebula from ten years ago that I have edited in GIMP.
