Nice work on both coins. Lighting can be really tough on objects that reflect like coins or metals (chips too!). One low cost solution that has helped me is these ebay light boxes (sometimes called tents), they come in many different sizes. The small ones only cost about $15. Placing a couple light sources (flash and/or continuous) on the sides tends to produce a somewhat even diffused light across the subject. I have used two boxes, one inside the other for even better diffusion. Below is an example of a small light box/tent sitting inside a larger one.

Thank you DL, I'll take your advice.
My 1000mm lens is f/11 but the 600mm is f/8. Any thoughts?


I'd probably start with the 600. Less tracking problems, and a bit faster f-ratio. I'd also increase the ISO for shorter exposures. You'll get a good field of view. When you become satisfied with what you get that way, then you can start changing whichever settings you like, and see what happens. I'll send one of my versions...
I like your second Orion shot, but it does seem a little clipped. Your sky should never be totally black, or you may lose some of the faint outer nebulosity. Otherwise a pretty good rendition of a difficult object!
