We love the StarSense Explorer collection. This model comes with a really nice quality 130mm aperture Newtonian optical tube. It uses high quality mirrors to deliver more than 20 times more light than the human eye will see on its own. To help you get the most of this scope we've bundled it with a red light flashlight that will preserve your night vision and recharge your cell phone, a 5mm eyepiece that will bring the magnification up to 130x for high quality planetary views and zooming in on the moon, and a nice set of filters to add contrast to those bright solar system objects. This is everything you need to get a good start looking at the moon, Jupiter, Saturn, and the 110 Messier objects.
