I'm just getting started using an old film scanner, and came across some of my old astrophotos.  Most I've examined so far have squiggly stars in them.  This one isn't bad, but it has other issues - not the least of which is dust on the negative.

If I remember correctly this would have been taken with a 4.25" f/5 Newtonian I bought from Ron Ezra, while I was working at Meade.  I had it mounted on an Optical Craftsmen/Pacific Instruments 1" shaft mount (that I still have), and guided with a Mayflower 60mm refractor, while sitting in a beach chair (anything higher I wouldn't have been able to reach the eyepiece).

That's actually quite good.

 

Do I see a hint of the Merope Nebula?

I still smelled like milk in the late 70's but, im guessing AP was no easy task in the olden days.

My limit seemed to be about 30 minutes unless my mind drifted sooner than that, along with the guide star, which occurred more than I care to admit.

 

Nice pic Tim.  Do you recall what the emulsion was?

Unfortunately no.  I don't think it was on the negative, whereas some other scans showed Plus X along the edge.  Different rolls.  I used to shoot with SO-410 before it was renamed 2415 Tech Pan, but I never did hypering.  

 

Somewhere I have color negatives of Konica 3200 film.  I didn't think it was as grainy as I had expected, and it was nice to only guide for 15 minutes at a time for decent density.

Great picture Tim!

 

The framing and simplicity of this is great, nothing overdone or super detailed - it's raw. It's a shot that looks just like what an eyepiece view of m45 through a scope would be.

Vey nice! Way better than my best from the golden days of my teens in the late 60s-early 70s. I also see the nebulosity.
