Emulating some old Sky & Telescope magazine centerfolds
« on: June 23, 2017, 09:38:50 PM »
I have wanted to emulate the old centerfolds in Sky & Telescope magazine and gave it another try last night.
My previous attempts have been foiled by airplanes, battery death, clouds, faulty cable releases, bumping the mount and just being a
klutz in the dark.
Even now, the shot from the Zenit suffered a scratch on the negative that I cloned out, so don't mind the extra or missing stars, argh!

I used an old Konica Auto S2 rangefinder with a 45mm Hexanon 1.8 lens
for the first photo and my pet Zenit E with a 50mm Zeiss 1.8 Pancolar lens for the second photo.

Both were made using expired Ilford Delta 400 film and then souped in the caffenol delta recipe for 8 minutes.

Each photo was made using a ten minute exposure.  I made others using different times, but ten minutes was the best of the lot.
Tracking provided courtesy of a Losmandy G8

These are from last night.
enjoy!

Those are great Becky, they do look like something from an old magazine.  How would they have tracked stars back then?  I'm sure they didn't have a device like your Losmsndy G8, it seems like it would have been difficult to do it by following a target but I suppose it could be done.

back in the heyday of the centerfolds of Sky & Telescope magazine, ( 1960 and 70's) they had tracking devices.
Plus, there is a simple device known as a "barn door tracker" that uses a 1/4-20 althread and not that works well for about 15 minutes of watching and turning it...
