I have a Coronado PST that I will be using to observe and image the transit. Being a Ha scope the prominences around the edge of the sun are easy to see but the colour that our eyes (and cameras) see at that end of the spectrum is red, red and even more red. The images you see of the sun yellow and/or orange are generally captured in monochrome and a false colour is added to the images later in processing. That's what I do.....
