A:AnswerThe purpose of an astronomical telescope is to both magnify and gather dim light. So, the actual answer in not how far you can see, but how dim. A bright distant might be easier to see than a dim nearby object, so depending on what you are looking at, there is no true answer as to "how far" you can see with a given telescope.
A:AnswerThe Travelscope is the simplest of all Celestron telescopes to assemble.
Extend the tripod legs just like you do with a camera tripod.
Attach the telescope to the tripod using the 1/4-20 thread stud just like mounting a camera on a tripod.
Insert the eyepiece and use the telescope.
A:AnswerA smartphone can be adapted to the Travelscope using the three-axis adjustable NexYZ phone adapter seen here: https://www.celestron.com/products/nexyz-dx-smartphone-adapter-kit
A:AnswerWhile it is possible to attach a DSLR to the Travelscope using the Barlow T-adapter seen in the following link, and a T-ring specific for your model of camera, a DSLR is a heavy load to hang on the end of small instrument like the Travelscope. A more practical solution would be to use the NexYX three axis adjustable cellphone adapter and a lightweight cellphone camera.

A:AnswerYou can always buy a telescope lens phone mount! The only tricky thing is lining up your phone lens to the scope-- especially if you have a newer iphone with three lenses.
A:AnswerNo, this is only for the sun. The strong filter needed to safely view the sun blocks out so much light that you won't see anything if using this as a night sky telescope. To view saturn, look for a telescope that isn't advertised as a solar safe scope.
