I like the diffraction spikes too. I remember stopping the lens down a bit, maybe f.4 or higher? It controlled a bit of coma in the corners in images with rich star fields. Although the stars in your image look great.

I noticed you used your ccd camera. Did you know if you attach the lens to a DSLR you can lock the iris in the lens so it stays at what ever f stop you choose when you remove it from the camera body?

Thanks, Erik. Yes - I did learn the trick for stopping down the lens from another post here in the IIS forum actually. Works really well. For this image I found that I needed to stop down the lens down to F7 before I was satisfied with the star shapes in the image. I am happy with the 100mm lens and it will make a good addition to my lens collection.
