Manual Alt-Azimuth telescope

Navigate the sky with a pan handle Alt-Az control with clutch for smooth and accurate pointing. Move the clutch in an up/down, left/right fashion to track your object in the eyepiece.

Accessories Included

The Travel Scope™ 80 comes with two eyepieces (20mm and 10mm), erect image diagonal, finderscope, a smartphone adapter, and a travel backpack. The two eyepieces offer different magnifications to view your intended object. The erect image diagonal allows for right-side-up viewing ideal for terrestrial subjects but can also be used for celestial objects. The permanently mounted finderscope will help you quickly center an object in your eyepiece for easier observing.

Smartphone Adapter

Image celestial or terrestrial objects with this smartphone adapter. With its light, rigid frame, this accessory allows you to connect any smartphone to any telescope eyepiece with an outside diameter of 45 mm or smaller. The additional magnification provided by the eyepiece allows your phone to capture great images of the Moon and planets. This smartphone adapter installs easily by clamping over the top of an eyepiece. The smartphone is held in position with the help of tightening knobs that securely lock your phone in place. Some large and/or bulky phone cases (including folio style cases) may need to be removed for the phone to fit in the adapter.

94124 2" UHC/LPR Filter by Celestron

Our 2" Light Pollution Reduction (LPR) Filters are designed to selectively reduce the transmission of certain wavelengths of light, specifically those produced by artificial light. This includes mercury vapor, and both high and low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e. sky glow).

The new ultra high contrast (UHC) LPR filter has improved contrast over the typical broadband filters. Sky background is darker, and contrast of emission nebulae are noticeably improved. The advanced technology coatings enable the filter to achieve an outstanding transmission of over 97% across the entire bandpass, with total blockage of prominent light pollution lines. The perfect filter for viewing nebula from light polluted skies, or for boosting the contrast of nebula from dark sky sites.

In addition to it's optimum spectral and optical characteristics, the UHC/LPR filter offers important features that set it apart and result in the highest quality celestial views:

The multi-layer dielectric coatings are plasma assisted and Ionbeam hardened using the latest technology for durability and resistance to scratching.

Improved transmission translates to maximum image brightness and contrast. Users of smaller, 4"-11" telescopes will especially appreciate the high efficiency, and larger scope users will love the rich star fields and detailed subtle nebular shadings that are left intact.

The high transmission, sharp cutoffs, and more moderate 60nm passband of the UHC/LPR filter retains a more natural view, yet significantly boosts overall contrast. Imagers will appreciate the broader bandpass and inclusion of an extremely efficient H-Alpha passband (656nm).
