巨物啊::070821_21.jpg::
说顶就有钱拿啊::070821_08.jpg::
这一套下来抵上我全部设备的价格了，好好利用吧！
这个还叫小杀器啊::070821_18.jpg::.......
光瞧瞧都毒死一片了::42::
CGEM吃力,平衡稍微不好就打滑,尝试换个大点的赤道仪吧

CGEM没极轴镜，怎么对极轴啊？软件操作怎么设置呢？没中文说明书，能指点下吗？

CGEM 运作声音很大，相对而言NEQ6就静很多了
半夜用这个，嘿嘿
我去找个CGEM的视频
另外，LZ头像要换了::070821_19.jpg::
恭喜ｌｚ进宝！
CGEM好像用软件对极轴吧。

买器材的人永远那么贪心，买完6寸看着8寸，买完8寸看这12寸，12寸还没捂热就盯着20寸的::06::

这个PDF说明书是英文的哦,
不过这些FAQ提问的问题, 应该包含绝大部分的解决方案
找了一个国外同好，用CGEM的心得，他提到说是用两星校准，
先发给你英文的吧，google翻译应该知道大概了
Two-Star Alignment
1. After powering up the CGEM, I started the Two-Star Alignment process. First, the index marks on the RA and DEC axis were aligned. Then, the hand controller prompted me to to select the first star.
Arcturus in the constellation Bootes was the first on the list of named stars and I noticed that it was still visible on the western horizon. This was a nice bright familiar star to start with. So I hit enter and the telescope started slewing automatically in the direction of Arcturus. Then, the hand controller prompted me to center the star in the viewfinder. After doing this, I was instructed to center it in the eyepiece then press the align button.
2. This process was repeated for the second star which was Vega in the constellation Lyra. I knew that I would be coming back to this constellation later for a view of the Ring Nebula!
3. Then, the CGEM prompted me to add a calibration star. I must have gotten too anxious to try out the goto and I by-passed this step. Not good! The goto was not accurate at all.
I decided to start the alignment process over completely and I added the star Altair for calibration. This is where it got exciting! The first object I selected in the hand controller (to slew to) was Jupiter. To my amazement, it centered the planet almost perfectly! And I must say, Jupiter and it’s moons were an awesome site in the eyepiece!
After my first stop at Jupiter, it was time to try a Messier object. I saw that the constellation Hercules was up so I commanded the CGEM to slew to M13 (The Hercules Star Cluster). Again, the goto was spot on! I was amazed at this point how easy it was to set up the goto on the CGEM and how accurate it was. One recommendation is to have a star chart handy at the telescope. The CGEM hand controller provides a list of stars to choose from at each stage. If you have a laptop at your observing site, then there is a free program called Stellarium that is nice to use.

建议加个遮光罩，提高目视及拍摄反差
来个羽毛调焦~~~外加无线控制调焦设备~~~赞啦
M13
CN上同好测试C11HD，像场很平，单张5分钟曝光{:1_245:}
single 5 minute exposure through the C-11 Edge
最后一张太假了吧，市内能看啥？？？？？

哈哈，果然被说中了。大博士啊，又丢人了。
CN上同好DIY了散热风扇，唯一不足的地方是，不能装上滤片了
买不起，只能合个影了
我也得来顶一下，虽然我都不怎么会用
