I use an OVAVUE by Brinsea to candle that works well. It also has an add on piece called an OVASCOPE that goes on top of the OVAVUE. Ya put the egg in the scope. It magnifies view, has dial to rotate egg for 360 view, web cam adapter, and possibly best of all..... you can use it in a fully lit room because egg is inside of scope. Sounds pricey but was under $65.
