However, you should always keep AA batteries in the scope’s battery compartment because if external power is lost accidentally and there is no internal backup, the scope will have to be rebooted and re-aligned.

The 8SE mount takes eight AA batteries, but we recommend only using these as a backup – get a portable 12-volt DC power supply and cord (Celestron even sells some meant specifically for astronomical use). Celestron’s Vibration Suppression Pads, while mildly inconvenient to deal with, will alleviate some of the jiggles with this scope, but not completely. This also presents the problem that you could knock the scope out of alignment if you’re not careful.
While it does work pretty well with the C8 optical tube assembly, it is not ideal to support the telescope and can be jiggly at high magnifications, particularly if you are using any heavy accessories or have the legs extended. The Celestron NexStar 8SE’s mount is the same as the one supplied with the NexStar 6SE. These let you attach a 2″ star diagonal, focal reducer, DSLR T-adapter, and other accessories. On the back of the 8SE optical tube are the industry-standard Schmidt-Cassegrain threads. The 8SE’s moving-mirror focuser does cause some image shift (the wobbling of the primary mirror on the rod causes the field of view to jiggle when focusing), but nothing too severe. The Celestron NexStar 8SE has a long Vixen dovetail bar on the side of the optical tube, but it is mostly for looks because the scope will only balance when the dovetail is all the way or almost all the way forward in the saddle. You can replace the screws with thumbscrews such as Bob’s Knobs to make things easier, but the thumbscrews seem to cause the scope to become miscollimated more often and interfere with attaching the lens cap. The Celestron NexStar 8SE scope is pretty good optically, though collimation can be tedious as with any Schmidt-Cassegrain – you must point the scope at a star (or an artificial equivalent), defocus it, and adjust the three small screws on the secondary mirror until everything is lined up. Despite revisions to the exact design of the tube, as well as the addition of Celestron’s StarBright XLT coatings and Hyperstar compatibility, the C8 is still essentially the same scope nearly forty years later.
