Meade 3.3 reducer

Quick questions, have c8, meade DSI II and f/3/3 reducer. Two things I want to know..
1. What is the equivalent in a eyepiece of the DSI II on the c8 with no reducer.
2. When using the 3.3 reducer, what is the field of view with the DSI II when using the both spacers provided. If someone can provide a picture with a dotted square against the moon, would be good.

"New Astronomy CCDCalc1.5"
Its a program, free to download. Might help...

Kon,

You will also get your answers by downloading Ron Wodaski's CCD Calculator. It's also free.

In the program, you choose from drop down lists your scope, your camera and your celestial target, so you can easily see the field of view.

I have tried to find the site where Ron Wodaski's CCD Calculator is but have no luck. The search results are for other calculators. Does someone have the correct link for it so I can download it.
