Astronomy, astrophotography and space images are wonderful to look at but like many aspects of our field, it requires visual abilities that not everyone has. #Accessibility is important, esp. when we share our images of the cosmos so that everyone has access to enjoy them. I have put together a little checklist that can be used as guidelines when writing your alt-text for your images. Many platforms now also allow you to set up your settings so that you can't actually publish the post until the alt-text is in - which serves as a good reminder. I hope this is useful! 👇 (background image is an old photo of mine) #Astronomy #Astrophotography #Astrodon #ScienceCommunication #AltText  

  • A prominent ring-like nebula. There are two features. An inner region which is not as dense and has blue-green hues. And an outer, more prominent ring of red dense nebulous gas that is clumpy. A small central star, the white dwarf, is energizing the nebula through its UV radiation causing different gases to be excited and emit different colours. Surrounding the central object, are several other stars. There is also text on the image that has title of “astrophotography alt-text” and bullet points: 1. Describe the main object (features, shape, colour, size, depth). 2. Describe its surroundings (isolated, dense star field, nebulous). 3. Describe its dynamics (orbiting, radiating, swirling, moving). 4. Describe science processes (merging, illuminating, exhibiting)
