first let me apologise if posting this question here breaks some forum rules I am unaware of; it's not my intention to bother anyone
I'd like to ask for your help finding the files for an old add-on: the fictional HD 28185 system by user Don Edwards. I remember it from the old days of Celestia and was quite inspired by it on many levels (it is a fictional version of a star system with several habitable moons orbiting a gas giant in the goldilocks zone; the planets and moons are named after volcanoes, so the main gas giant is Erebus, the moons are named Hekla, Yantarni, Methana etc.). Recently, I tried to find it to have another look at it, but alas, it seems to have been lost in the mist of time
I certainly cannot find it anywhere in the usual places and the author of the add-on appears to have gone inactive.Does anyone still have it or can point me to a place where I might find it? Thanks.

It seems to work well enough (at least the 'HD 28185 System' if put in the 'extras' folder; if both are used at the same time, it doesn't); EDIT: several textures (the moons "Pavant" and "Progrmoni") seem to be corrupted, others are fine.
