This is my first attempt to do startrail with film!
Single shot of about 5½ hours exposure


The shutter was open for almost the 1/4 of the duration of the sidereal day, thus recording almost one-fourth of the circular path that each star follows around the Polaris..!

Location: Eastern Crete, Greece.

Stuff used: Zenit TTL, Revuenon 35mm f/2.8, Ilford HP5+ 400ISO
Developer: HC-110 (Dil B), Developing time 5min @ 20oC
Scanned with Epson V550, Some contrast improvement with GIMP

That is classic.   I remember we always worried about the film "fogging" with long exposures.

You can see some of that here, but that's the way it's meant to be !  Nice project and result.

Very nice! I used to do a lot of those. PS: I notice that the handedness is flipped in your image (I recognize the stars).    Tom

I like that shot very much. Did you use the lens full open?

True! It seems that i scanned this negative with the shiny side on Transparency Unit ( not the emulsion side which is the correct way)
so i will try again the scan with the right way, it may (?) also improve the contrast of the background.
Thanks!

No, I think at this shot it was  at f/4, while the maximum of the lens is f/2.8

Nice job!   Something special about film star trails!  

 

How dark is your sky?

I would say the sky was about 4 in Bortle scale at the start of the exposure but unfortunately i overslept and some very  faint twilight had appeared before i stopped the exposure..

Wow! Someone is still using a Zenit. I started in 1977 with a Zenit E; the only 35mm SLR I could afford at the time (IIRC it cost me $75). It was stolen years later and I replaced it with a Pentax K1000, which of course was still a budget camera but in almost all respects superior. (The K1000 wouldn't have survived being run over by a Russion take like the Zenit probably could but that was the only advantage of the Zenit.) The TTL has the one feature noticeably absent from the E: through-the-lens metering (hence its name).
