    Was very well worth the wait.
    Images in the 50mm teamed with a ZWO 174mm camera are amazing. Surface detail, sun spots, and erruptions are clearly imaged.
    Thank you.

    I was quoted 8-10 weeks and get the shipping notification on week 10. It arrived the next day, I was very pleased it arrived in the quoted time. The scope is wonderful! Has great views and feels solid.
