The Amazon-exclusive Celestron Travel Scope 70 kit (21035-ADS): the 70 mm travel refractor with backpack and full-height tripod, plus an additional 4 mm eyepiece and a 3x Barlow named in the title.
This is the Amazon-exclusive version of Celestron’s Travel Scope 70, model 21035-ADS. The title adds an extra 4 mm eyepiece and a 3x Barlow to the usual kit: the 70 mm fully coated refractor, full-height tripod, 20 mm and 10 mm eyepieces, a custom backpack and astronomy software. An alt-azimuth head with a panning handle and clutch points it.
On November 7, 2026 this kit cost about $245 from a third-party seller, while the standard Travel Scope 70 was $89.99 from Amazon. The extra eyepiece and Barlow do not justify the difference, and the score on this page reflects it.
A 4 mm eyepiece on a short 70 mm refractor already pushes the aperture; in the 3x Barlow it goes far beyond it. The useful extra is the Barlow with the 10 mm.
On November 7, 2026, Amazon.com listed it at about $245 from a third-party seller.

The title adds a 4 mm eyepiece and a 3x Barlow; the bullets describe the same telescope, tripod, backpack and 20 and 10 mm eyepieces.
Little. A 4 mm on a short 70 mm telescope gives high power, and with the 3x Barlow far more than 70 mm can resolve. The 10 mm in the Barlow is the useful combination.
At the prices seen on November 7, 2026, the [standard Travel Scope 70](/reviews/travel-telescopes-celestron-beginner/) at $89.99, plus a Barlow if wanted, costs far less.
7.2/ 10
The same Travel Scope 70 with a 4 mm eyepiece and a 3x Barlow added, at nearly three times the price of the standard kit when checked.
