Regarding this telescope, the telescope body, the eyepiece lens 25 mm (53 times), the star pointer (it is the equal magnification viewfinder), the control box, the Japanese and English instruction manual were the initial set.
Moreover, it is confirmed the operation in this exhibition (automatic introduction). However, with regard to the star pointer, LED operation is not confirmed due to battery exhaustion.This time, we will attach documents of usage, introduction, operation method (for NexStar 5) searched on the net for reference, and Messier star database as an appendix.Also, because the star pointer is 1: 1, we will also attach a single glasses (OPAL optical 8 × 40 field 9 °, wide angle single lens with an apparent field of view of 72 °) that we used as an aid for the viewfinder (There is dirt on the objective lens).The purchase of the telescope was about 10 years ago, but it was used only a few times. I decided to sell it because I was addicted to the star viewing with the low magnification large diameter binoculars and he had no opportunity to use it.In addition, because it is home safe, there are no scratches or dirt on the lens, but the body has a few scratches.Best regard.
