Well..... I'm ready to try some real astrophotography now.....
Any last minute tips and advice are welcome and greatly appreciated.
I just got my hands on a fully serviced, beautiful Olympus OM-1N MD. It has the 50mm 1.8 Zukio. I am still amazed at how well some of these cameras have been taken care of (lucky for me).
I am hoping to do some shots the next couple nights.... Weather permitting.....
Here is what I had planned..... Please give input if something seems amiss.
I plan to use F stops at F/2.8 and F/4. 1,5,10 and 20 minute exposures of each. Then possibly a couple fast 1.8's.
The film will be Kokak Elite Chrome Slide film. The plan is to piggyback on my Skyview Pro 127. When properly polar aligned it does track fairly well. I can keep an object centered while imaging planets @ F/36 for up to 30 minutes.
Any comments welcome....
Thanks,
AJ

Hi AJ. I can't give any advice really, but I do wish you luck. I'm still struggling with my photography. The sky has not been very helpful lately with all the clouds. I look forward to seeing your pictures and getting some advice from you.

You're all set - you've got a good span of exposures that you'll learn a lot from.
Have fun!
Suk
PS Nice camera.

I would at least bracket 1, 2, 5, 10, and 20 minutes. That would give approximately one stop between each exposure. Since this is slide film, I would do a half-stop bracket because of exposure latitude - 1, 1.5, 2, 3, 4, 6, 10, 15, and 20 minutes. That would also keep you busy for one hour.

Suk and Wilash,
Thanks for your input... I was not sure if I had a good enough span of exposure times. This will use more of the film too (less waste).
I'll do it like the latter.....1,1.5,2,3,4,5,6,10,15 and 20. At f/2.8 and f/4. I'm assuming any higher would be a waste of time?
Regards,
AJ

AJ:
Any more than 20 minutes at f4 is probably your skyglow limit if your area is anything like mine.
The rule of thumb I use is 10 minutes @ f2.8 @ ISO200 is the skyglow limit for my area. As the focal length increases beyond around 180mm, I add time, so I typically shoot 300mm @ f4 @ 30~40 minutes @ ISO200.
Suk
Cheers,
