Samsung Note 4 holder to attach to the finder scope on my Skywatcher Dob telescope. I use it to help find stars and DSO's with Sky Safari. My finder scope is a 9x50. The ID of the bracket is 53mm. The bolt holes are to suit an M6 bolt I modified this thing with Tinkercad: http://www.thingiverse.com/thing:610536 The Note 4 clip fits perfectly with case attached
