Have sold my astroscan and have the following accessories left:
Image erecting prism with separate focusing tube. It really works and
particularily well for nature observing. Also the separate tube is
far more convenient than the having to insert the prism in the regular
tube. At US$40 less than half of new cost.
Extra table top base with small 20" high tripod places the scope
at a convenient level for viewing while seated. US$30.
