How to Use Celestron Powerseeker Celestron’s Nexstar 5SE?

Keep calm on using the NexStar 5SE from Celestron, as it is a straightforward tool. You must have the mount, the main tube, and a tripod, a diagonal, and one or more eyepieces. You may also have a Barlow lens. You can connect a small, energy-saving telescope should as a finder scope.

If the telescope is already attached to the mount, then slide the diagonal and add an eyepiece to show what you want to see. During installation, it is likely that the finder scope will not be aligned.

I suggest finding a distant but bright street lamp (something that does not move) or a red light on top of the tower in the central area, and then adjust the finderscope (there are three screws for it, and if you do not use it, you need practice, but you understand it very quickly).

There should be a button on either side of the focus that you can use to press the focus tube to get the right centre. So, what else do you need to know? However, you will have a useful Celestron Nexstar 5SE manual that will help for the rest.
