    This review is about the lens diameter: 50 mm

    For its price, it offers great satisfaction, but the travelscope 70 is the best investment for a very cheap telescope. The price difference is very small and it adds 40mm of focal length, which makes a significant difference. The tripod is the simplest there is, of course. Anyway, both are good telescopes for someone who doesn't have a big budget and wants to try or start observing the night sky. The good thing is that you can upgrade it with better accessories (from cheap to very expensive) for much better results, which of course you can keep for when and if you buy a better telescope. I regret getting the 50mm instead of the 70mm, but nevertheless, it is worth it and I enjoy it. Finally, don't forget that you see more when you are away from city lights and have good weather. If the sky is filled with stars and you know what you're looking for, you will be impressed.

    This review is about the lens diameter: 50 mm

    We recently bought it for our 6-year-old son and we were very satisfied! The clarity of the moon's image is unique! Although beginners, the setup was very easy and locating the moon and planets was a breeze (with the help of a mobile app for the position of each planet). Note that the planets appear faint. We recommend it!
