Digitarium® Alpha 2+ Fixed Digital Planetarium System
This model has been discontinued. Please see our current models.
Product Overview
We recommend the Digitarium Alpha 2+ Fixed for fixed domes up to 56 feet/17 meters in diameter if you can not afford a higher resolution model. The improved projection quality over the Digitarium Alpha 2 Fixed makes this a better option for a fixed dome if your budget can cover the added cost.
