First I get the Ultima 80 to watch the mountains from my balcony in Santiago,Chile and I start to watch the moon and some planets (Jupiter and Saturn looks small but very sharp and clear) and I liked so much that I want to improve it so I sell it and get Ultima 100.

I wanted a spotting scope for birding, nature watching and large planetary astronomy. The moon and larger planets are awesome. I am very happy with my purchase. Spend the money on a beefy, stable tripod however. This is not a toy. It is a well-made spotting scope that is on the heavy side.
