Telescopes with an 800mm focal length

Long-reach optics for deeper sky views

A focal length of 800mm marks a transition into more serious astronomical observation. These tubes are longer than entry-level travel scopes, allowing for higher magnification without the need for extremely small eyepieces. This makes them particularly effective for observing the details of the lunar surface, the rings of Saturn, or the cloud bands of Jupiter.

This set includes both refractor and reflector designs. The refractors use large front lenses to provide crisp, high-contrast images, while the reflectors use mirrors to gather significant amounts of light, making them useful for observing dimmer celestial objects like nebulae.

Key features of the 800mm collection

The telescopes in this list are generally paired with full-height tripods and mounts designed to handle the weight of a longer optical tube. You will find several specific configurations in these listings:

• 90mm aperture refractors for bright, high-definition planetary views
• Large 203mm reflector models for deep-space light gathering
• Adjustable AZ and EQ mounts for tracking celestial movements
• Accessory kits including Barlow lenses and color filters
• Custom carrying bags for transporting the long optical tubes

Selecting the right aperture

While the 800mm focal length is consistent across this set, the aperture varies significantly. A 70mm or 80mm refractor is a great choice for a beginner who wants a portable but powerful setup. If you are looking for professional-level light gathering, the 203mm reflector models provide a much larger surface area to capture faint starlight.

Each listing provides details on the mount type, such as the stable stainless steel tripods found with Dianfan models or the variable LED finderscopes on Tasco units. Check the individual brand pages to see which accessories, like phone mounts or specific filter sets, are included with the tube.
