What do you mean, as a positive image? Just download or copy the image and invert in some program like Photoshop/Paintshop Pro.

as in processed in modern fashion to see what data could be wrung fom it. the negative already shows the front dust lanes with amazing clarity. I found this while looking for information on observing visualy with very large telescopes.

Thanks! the amount of detail in that plate is outstanding despite the outdated tech. It really emphasizes the reason for combining different exposure times to avoid washing out the core.
