I got a sheet of a dark red acrylic (9" x 12" x 3 mm thick) from Century Plastics in Phoenix for $5. They are located off 16 St, south of I-10 (around the Salt River bed). If your astro software does have a red display mode, ensure that makes all components red. Some leave certain screen elements unchanged. Depending on the quarry, I sometimes find that even with a red-filtered and manually dimmed display the screen is still just too bright. Of course YMMV.

The only other one I've found is on-line from Ideal Astronomy - it's a reasonable price, but I've never known anyone with that brand, so I don't know if it's dark enough. My laptop does have a brightness adjustment. -- See message header for info on list archives or unsubscribing, and please send personal replies to the author, not the list.
