The screen is in working order. I want to remove the screen and use it for making flats. Is it possible to somehow wire the screen where it just displays solid white and just turns on and off. I'm not sure if this is possible, I know enough about electronics to be dangerous. Any help is greatly appreciated!! wynn -------------------- Orion 120 ED Refractor Feathertouch Focuser Orion Atlas EQ-G goto mount Orion 80 guidescope w/Starshoot autoguider AstroTech 2" quartz diagonal Canon Rebel XT Post Extras:       grendel sage Reged: 04/12/09 Posts: 244 Loc: Canterbury, Kent, UK Re: flats from laptop screen?

This way, you could just set the chart on the screen you want, turn it on, and you have black on read easy to read star charts. No shining a flashlight around the page trying to read it. -------------------- Daren Covington, GA Post Extras:       wmyers member Reged: 01/23/08 Posts: 44 Loc: High Point, NC Re: flats from laptop screen?
