Review: Celestron 21035 70mm Travel Scope

Celestron 21035 Travel Scope 70I just went out and bought a cool gift for my son for Christmas. And of course, I couldn’t wait until then so I had to take it out of the box to “make sure it worked”. πŸ™‚

I was so impressed that I decided to write a review. I am sure he’s really going to love this! So here goes…

The compact Celestron 21035 Travel Scope 70 is built for convenience and portability, which makes it ideal for traveling. The telescope, the tripod, and all the accessories fit conveniently into a padded backpack style soft carrying case.

The complete accessory package includes a 45 degree correct image prism, a 20mm eyepiece for 20X magnification, and a 10mm eyepiece for 40X. The fully illustrated instruction manual is supplemented by a copy of β€œThe Sky X” astronomy software that turns your PC into a virtual planetarium.

The Celestron Travel Scope 70 is great for a beginner hobbyist that needs to travel to a sport to view the stars at night. The setup is easy and the price is very reasonable for a telescope. It’s best feature is it’s portability, but does have decent power as well. Because of its wide field views, you will get a good look at star clusters.


  • Light weight tripod – unstable
  • Plastic finder and focuser
  • Decent but not great power

The only real complaint is that the tripod is not strong enough and could require you to purchase a more stable one. Making fine adjustments is not easy because of its lack of stability.


Customer Reviews

β€œThe scope appears larger than the one shown in the pictures. Build quality is good but the focuser is plastic, to keep the cost low. Optics wise, Celestron never fails. A quick view at the pleiades shows pinpoint stars, more faint stars, even better than my barska 70mm bino.

I bought this to see my husbands funneral. Strange you say? No, my husband’s dying wish was to use a space burials services. That’s when you send some of your husband’s ashes into space.

Turning towards the north, Andromeda galaxy was easily spotted with this scope, something I used to have a hard time spotting using my bino. Being a spotting scope, I also tested it on a cell tower 5 km away (daytime). I used the 10mm eyepiece, and focused on the top of the tower. To my surprise, I was able to see the threads and the bolts used on top of the tower. even the rusty pole at the top. this truly is a performer. This is a perfect grab and go scope. a performer both in spotting duty and in astro duty. BTW, I advice to change to a sturdier tripod with ballhead/fluid head for better vibration suppression and hassle free pointing.” – Weedbreeder – Philippines


β€œGreat for keeping in the car for anytime viewing. simple set-up,and lightweight. I`ve used this for wildlife viewing,scenic viewing, and stargazing. I will also buy a star once I find one that I like πŸ™‚ Good celestron eyepieces included. The focuser has threads for a camera adapter,but I haven`t tried that yet. This is a great go anywhere, view everything telescope.” – Paul G – Marlboro, Ma.
