the FTn doesn't have Time exposure mode like the OP wants. the F2 does. correct?
The latest version of the Sekonic L-398 is not selenium but in fact amorphous silicon. So it's nice that you can still buy a new battery-less meter, and maybe amorphous silicon has not the same issues as badly kept selenium cells.
Nevertheless, bear in mind that the 398 uses a heavy magnet and a galvanometer to move the needle. I know next to nothing about electricity v. magnetism, but I thought you would like to know. I'm pretty sure most selenium meters work from the same principle.
The "T" setting allows very long settings without holding the button the whole time. With "T" you can start an exposure, go to sleep for 8, wake up, and stop the exposure. Very handy for star trails and painting with light.
Good morning, Mark;
You do astrophotography also? Neat.
Cable release! Cable release!
They lock.
Okay I'll nibble at the bait a bit here.
Why would I want something different than an F2?
The best thing I've found for framing/composing wide field astrophotographs (i.e. taken with camera lenses rather than a telescope) is to use a hot shoe finder designed for rangefinders. The Cosina Voigtlander hot shoe finders I've tried show several orders of magnitude dimmer stars than any SLR I've tried, and many others will work as well, perhaps better. Commonly available focal length coverage from manufacturers are for 15, 21, 25, 28, 35, 40, 50, 75, 85, 90, 100, and 135 mm fields of view. They can also be found used. They make framing up a constellation a relative breeze.Frankly, for astrophotography I'd be more likely to use a more modern body with a brighter viewfinder. It will make aiming a lot easier.
Another radical suggestion for your astrophotography: a Nikon EM. B does not use batteries in this body, and it's the smallest 35mm Nikon film SLR with a decently bright viewfinder and silky-smooth film winding.

Are we sufficiently OT yet?

The EM looks like an interesting camera, I could see using it is in street photography, but being stuck at 1/90th without the battery is a deal killer for the task at hand.

But, here's a question that I'm embarrassed I don't know the answer to: Doesn't every camera with a flash connection, whether it's a hotshoe or plug, generate some sort of electrical impulse whenever the shutter is tripped? Or does there have to be an activated flash unit connected in order for there to be a current generated?
For astrophotography with a film camera, I am less likely to use a more modern body because few of the newer cameras have interchangeable viewfinders and view screens. I prefer to use the Nikon F2 with a type M view screen. For a viewfinder, I prefer the DW-2 6x magnifier finder or the DE-1 standard viewfinder with a 10x eyepiece magnifier attached
Marty Forscher, the legendary camera technician and inventor, told me that the Nikon F2 was and is the most durable 35mm camera ever built. He said that if he were stuck on a desert island and could have only one camera, the F2 would be his choice. You could put up aluminum siding on your house using the F2 as a hammer.
Occurs to mention that anything sparking at all-- say a chrome plated camera dropped on an industrial steel floor or truck bed could be fatal in an explosive environment. Now, I'm not 100% certain but strongly suspect that a chrome body would spark, even if the chrome is over plated over a brass or stainless base. This seems to me more dangerous in an explosive environment than a little 1.5V DC battery arcing at switch-on. (This is the reason for brass wrenches and hammers, no?).
One could choose a painted brass black body early F2, but even then, strap lugs are still chromed on most cameras.
Rules is rules and no one may challenge you if a specific prohibition isn't clearly specified, but personally I'd rather not blow up, than not break a rule.
All that said, the Pentax LX would be a great choice outside of the brand.
