Refractor telescopes use one or multiple lenses to bring the image into focus. A doublet uses two lenses, a triplet uses three and a Petzval uses four. Refractors are amongst the most popular telescopes for the astroimagers, because they usually produce images with the best colors. In general, refractors are much smaller than the other types of telescopes, which makes them perfect for the nomad astrophotographer who can't carry a bid mount. They are also extremely popular for the beginners who are looking for a portable telescope for observation. Let us help you find the perfect refractor to get started in your celestial journey!
