This shroud covers it all.

This shroud blocks out all of the light trespass in my area. It has two slots for the eyepiece and the finder scope. A must have item for this instrument.

Nicely emersive experience.

This lens has me looking into more 2" eyepieces from the same series. The views are amazing and Crystal clear. Literally room to stretch out the eyes.
Ring Nebula is so beautiful through this lens, truly breathtaking.

Fast, reliable, spot on customer service.

I have been in the market for an Ultralight 12" Dobsonian telescope. Ryan helped me with useful information on Explore Scientific telescope. What an amazing purchase. A high quality instrument and a dream come true for collimation. Great company, great scope.

Coming equipped with two decent eyepieces and an adapter is nice. Will upgrade to a 2" eyepiece one day, but not in the budget right now. Thanks to Ryan for help with ordering.

Easy

I'm enjoying the telescope very much. It's not too hard to assemble, although very slowly the first time.
