自取？LZ离那边近么？油钱不便宜哦呵呵~~~ 如果还有的我也去买一个去~::070821_08.jpg:: 回复 2# kidschwein
是自己开车去取啦，不过刚刚卖家发邮件说可以各自开一半路程。就不知道这个架子是不是赤道仪？看起来也不想经纬仪，重来没看到过这种架子。以前只用过一个60mm的小折射，这次算是鸟枪换炮啦，哈哈。 这只不过是老款C8，双叉臂经纬仪，加个赤道仪楔变成赤道仪式的，可以抵消场旋，进行拍摄。配件比较齐全些。 回复 4# 3dmaxhy
看上去不是赤道仪，是叉式经纬仪。不过按LS说的应该是加一块东西调整出一个仰角，之后就可以做赤道仪用。不过那样的话不知道跟踪速度之类的有没有问题~~不太了解~~500多块买一套东西也不算贵，慢慢再倒腾哈哈~~ 回复 3# 繁★之夜
如果只要C8OTA的话astromart上很多啊~~都不贵的，3,400刀搞定~ 这只不过是老款C8，双叉臂经纬仪，加个赤道仪楔变成赤道仪式的，可以抵消场旋，进行拍摄。配件比较齐全些。 ...

celestron就是靠C8发家的，当年的镜子都是纯手工一台台弄出来的。质量过硬。光学当然也是够硬的。只不过过了多年，镀膜比较脆弱。
但是LZ，只花3000多RMB，买一台，也是很划算的，可以算是高端的入门机了，用坏了不心疼。其实，最值钱的，还是那些配件，主机卖了，或者改造，配件还是照样能用。 老款的配件，质量可是相当好的。
