I have 4 rolls of 135 format Konica Centuria 400 negative for sale. They cannot be easily accessed in US and are suitable for astrophotos, especially H-Alpha. See my pictures for an example.
I got these films from Japan and store them in my frig all the time. Because I hardly use 135 format, I decide to sell them. The expiration dates for these four rolls are, 2004/4, 2004/8*2, and 2004/10. I prefer selling them together. $17.0 plus actualy shipping.
