No finder scope, making star-hopping difficult. Provides a " wow factor" for young observers. Navigation will be tricky too, since a finder scope is not supplied either.ĭespite the shortcomings, we couldn't wait to see what the FirstScope was capable of - especially given that we could get started in astronomy with a quick slew of the telescope tube.Ĭelestron FirstScope 76: First light and functionality Unfortunately, these aids are only usually on the more expensive models, meaning that it was quite a task trying to collimate the FirstScope, since the primary mirror isn't adjustable and a collimation cap or eyepiece isn't included with the telescope. With Newtonian designs, the two mirrors within the tube should be aligned and astronomers usually achieve this process - known as collimation - using thumbscrews to adjust the optical system. You'll notice that the telescope's base is short, meaning that you'll need to place it on a table in order to use it comfortably: a hindrance for some observers, however, if you have children who have been pestering you for a telescope, the FirstScope is the perfect solution, especially given its small build and ease of use. 
However, considering what you get for the price, we did note that the telescope's plastics are not glossy and cheap compared to other instruments that fall in a similar price range. On close inspection of the overall build, we discovered that the finish isn't perfect with traces of glue apparent on the tube. (1.95 kilograms), the FirstScope is ideal for those looking for a "grab-and-go" instrument. The Newtonian reflector is supplied with two eyepieces - 20 mm and 4 mm - and possesses a fast focal ratio to provide a wide field of view that's ideal for not just viewing the planets and the lunar surface, but also allows the observer to view diffuse, wide-angle targets such as star clusters.
When unpacking the FirstScope, you'll notice that it is already preassembled with only a finder scope needing to be affixed to the telescope tube.
