stellarium的问题!
我的stellarium和望远镜连接之后,点slew,goto上出现点击SLEW后 手控器上显示slew limit warn
change slew limits in 'scope setup'
这是怎么回事啊
没有装scope? 这个真不知道了,看起来像是达到了什么限制或者什么东西没有打开,帮顶 我的slew limit压根就不起作用,不知为什么 jackaaa 发表于 2012-1-16 12:16 static/image/common/back.gif

恩,怎么改也没用,就是不起作用!
怀疑你的串口连接有些问题。换个串口,或重新插紧 本帖最后由 goldenham 于 2012-1-16 23:07 编辑
问:我把Celestron GOTO地平式望远镜弄到三脚架上,手柄显示slew limit警告。怎么回事?
答:大概不是什么问题。
slew limit被用来防止望远镜撞击自身或者其他东西如照相机,也用来防止望远镜指向地平线下。
因为地平式挂载台一般默认limit是0度,即挂载台的平面位于水平面。但是当它安装到三脚架上的话挂载台0度相当于天赤道0度,这样观测赤纬为负的目标如Orion Nebula的话就会报错。
你可以直接按ENTER键忽略这个错误,或者设置新的slew limit,设置成当地纬度减去90度即可。

I have my Celestron GOTO Alt-Az scope on a wedge and the hand display shows a slew limit warning. What’s wrong?
Answer
Probably nothing.
Slew limits are designed to stop your scope from either hitting itself, an attached accessory like a camera or pointing below the horizon.
Since an Alt-Az mount usually operates with the base horizontal, the lower slew limit is usually 0 degrees. However, on a wedge, the plane of the base of the mount now coincides with the celestial equator. So any slew command to an object like the Orion Nebula will result in the slew warning.
You can either simply press ENTER to bypass the error or you can set new slew limits. The new lower slew limit for a wedge-mounted scope should be your latitude in degrees minus 90.

谢谢!
8楼是正解.这个限制是可变的.也可恢复出厂设置.
