Thanks guys. I'm not sure whether I like them. But I can see how Mike could find the idea amusing, on the other hand it's also very creative.

I thought that most people only used refractors for photography because the contrast was better and something to do with the center of the image being clearer. But it looks like there is a diffraction spikes verses non-diffraction spikes debate as well.

So iceman, you are saying that if you do short exposures with a Dob or RC that do won't get the spikes?
