Another idea that has come to me has been to pierce holes through existing negatives of the family and try to print them. I have no idea how this will turn out but it's worth a try, and the results could be interesting. It also means using the darkrooms which I havent done in a long time but I may as well use them while I have the chance.
The third idea I have is to create these constellations on black paper by piercing them with a pin and putting them in a lightbox (or a window for now just to test) and see what it looks like. If this works then making an entire "night sky" of my families house paths could look really good.
I'm really glad my lecturer mentioned the space thing as now I can involve a real passion of mine into my work. Not that photography isn't a passion, but space is just...woah!
