I was speaking to Jurgen from Holland today and he said that he could not imagine what a 7" secondary mirror would look like compared to the 66mm (2.6") secondary on his current scope. Here is a comparison picture for you.

OMFG that is bigger than most people's primary mirrors! How much does it weigh? What scope does it fit? |

I'd have to weigh it, but it is one of the new Super Duty holders from Astrosystems, so it is really beefy. No collimation shift with this bad boy. It goes into our C40 telescopes. |
