This app shows stars the telescope observing that is connected to your phone vir Bluetooth. This is a successor of my old app TeleSkyMapBT(https://play.google.com/store/apps/details?id=com.nekomeshi312.teleskymapbt&hl=ja). By changing drawing engine to Sky Map opensource project(https://code.google.com/p/stardroid/), it draws stars smoother and faster without network connection. It gets the direction of telescope from rotary encorders connected vir Arduino. Schematic and farm are disclosed at http://p.tl/h3xp. This firm requires NewSoftSerial Library(http://dev.surfgrid.org/).
Compare to original Sky Map app, following points are imploved:
1)The number of stars is increased and can be choosed from 1,600, 15,000, 40,000, 80,000, 120,000(Original Sky Map has 1,000 stars). But choosing rich starchart might cause longer loading time and out of memory error.
2)The icon of Messier heavenly body is changed by the type.
3)Screen can rotate in the pole axis center or zenith-nadir axis center.
4)The location of celestical object not included in this app can be searched from SKY-MAP.ORG(http://sky-map.org/).
