Newbie Coolpix 995 question

I am looking to get the Coolpix 995 and the 18mm Scopetronix wide angle eyepiece (according to scopetronix website, the eyepiece can screw right into the camera). If you have this hooked to your scope, how do you aim the scope(I have a motor driven CG-4 and a Telrad finder but no GOTO)? Assuming you use the LCD screen's live throughput to confirm the correct aim, do you see the same/more/less than your eye could see without the camera? And do you get the full wide field view (these eyepieces are 66degree AFOV) in the LCD screen or is it vignetted?

Thanks for your help -

Ryan, I have a Coolpix 995 that I use with a Meade 13.8 SWA on my AP 6" Starfire. I aim the scope with an accurately aligned optical (8X50) finder. You will get vignetting if you zoom the camera to wide angle. To avoid vignetting, simply zoom out until the entire field is unvignetted. Of course, the more you zoom out (longer camera lens focal length) the higher the magnification. You realize that using a digital camera intended for "normal" photography can only be used for photos requiring exposures of 1 second or less. So you are limited to solar system objects - sun, moon and planets. Still this is great way to get started with digital astrophotography. Good luck with your photos.
