About five or six years ago, I made my last analogue astrophotography attempts - sadly, I haven't had time since then. I was still more into film than into digital astrophotography and had (if memory serves me right) an ASA200 film in my camera. I attached a 300mm objective, set it up to about f/4, mounted the camera on my 102/1000 achromat, used as guider with my haircross eyepiece, and intended to capture the Plejades for 60 minutes. No worries, I had the mount track the guide star and applied some regular manual corrections...but it was a real pain! But then I wondered how much more I might see if I go to 120 minutes, at which time I thought "The heck with it!" and extended to 180 minutes. The film was not full and I did some daylight images with the rest over the coming months. But then I forgot to have the film developed and it is still in the camera. I would like to have it developed once I get back home but I am wondering what I can expect from the Plejades image.
I only recently learned that once you expose past a certain time limit there are no more benefits and only the background gets brighter and brighter. Moreover, do I have to fear that the years in the camera degraded the film in some way, although it was stored dry and out of heat? Please tell me I will have a good nice photo to look at... one that was worth the efforts.
