This is my initial processing attempt at M33 the Triangulum Pinwheel.
Comments and critique always welcome, Thanks for the Favs.

The colored felt is attached to the hardware of a delay circuit, which is embedded underneath the white felt. By squeezing and pulling on the colored felt, sound can be sculpted by controlling the number of repeats and the level of feedback happening in the circuit.
Back lit images are always tricky and this image has been no exception. The trick is knowing just how much to go into contrast without losing detail or there can be a tendency to head towards over processing. This particular image has also been awkward due to the healthy mixture of warm bracken bathed in winter light and the cold blue frost. I have tried to proses this image before, but I was always slightly bothered by the eccentric colours, but I felt it was time to let it out of the bag…
This is a re-process of messier 13 which i photographed a couple of months back. I thought i could improve on it and managed to bring back some star colour and a bit more data.
