M42 - NGC1976 - Orion Nebula (1991)  
Orion

One of my very first film astro images (1991), recently reprocesed		  
 
It was taken with rather archaic methods: film SLR, no guiding, narrow camera adapter which produced a lot of vigneting, no filters,... Anyway, a very pleasant result for these old times.
