Re: My new old Ektar lens
Congratulations! They are fine lenses; I regret selling mine. It will serve you well, I'm sure.
Re: My new old Ektar lens
I hope I can find a way to use it on my 4x5, lest I get a 5x7. I am playing with 8x10, but would want a lightweight field camera in 8x10 for practical applications in landscape and such. Even astrophotography.

Great lens !
I'd like to have one !
Let me recommend this book: A manual of advanced celestial photography (Walis, Provin) (under $10, ebay). It covers interesting topics about film, like hypersensitization to avoid LIRF, and how early astrophotography contributed to basic scientific discoveries, as long exposures allowed to show what eye could not see.
Re: My new old Ektar lens
Thanks for the reference.
Re: My new old Ektar lens
I ordered the book at Abebooks.
Light reading...

Randy, I'd say that you won't regret, I found it is a really interesting reading, in fact it was a very good recommendation from LabRat, IIRC.
Re: My new old Ektar lens
I have had such bad luck with the Ilex 5 shutter. At the moment I have two on a shelf waiting for the $ to have them repaired.

I wish I had them. I always on the lookout for Ilex shutters. They were built like tanks by an alarm clock maker.

This is a tank for sure. As for astrophotography the big thing is usi GA 4x5 for the camera where you would actually put the dslr or dedicated ccd. How to get an image circle large enough to fully cover 4x5. Right now it's around 2 in. But how cool to make 1 exposure over a few hours and no noise reduction or stacking. Mounting 4x5 to telescope or mount directly a 14 in lens should provide a great image. Just need to make sure system is tracking flawlessly over many hours.
My one mount can do that, my home Observatory will have a mount as well can do that. Very pricey though for home mount.
