相机我不熟,不过听说450d不错…9i2l$k(PO"] ~2l
有钱就烧5d,冷冻ccd吧…

就是没钱才考虑非单反啊

我现在不知道佳能 S5 IS的镜头是否能用, 因为变焦会收缩, 也没见哪位兄弟用普通数码, 所以先问问

考虑数码相机呀…,?

听说有人直接把数码的镜头拆了接望远镜拍摄,或许楼主大胆的可以试试…$y6I"b2FIdB

上个数码单反吧,C家的450D&40D,N家的D80&D300都是不错的选择

实在是想上CCD,找找QHY博士或者++0,他们有冷冻CCDbbbb3

楼主似乎考虑的是非单反的数码dc呀,更别说是冷冻ccd…

没钱就买个最便宜的单反吧,就像我,上了个350D,感觉还不错!bbbb32

我觉得单反不大适合我, 又不知道普通dc如何, 唉, 古人云, 我不入地狱, 谁入地狱, 估计兄弟们都没用过dc, 也不知道情况, 让俺来趟雷吧

别玩花了,整个2手数码单反吧,消费类数码相机在很多方面都比不上DLSR的

天文玩dc要有心理准备…8b U&H6s|2f-m,X
要是我宁愿用好一点的摄像头或廉价的ccd…

This is the scope (TEC 140), mount (AstroPhysics 900GTO), and camera (Canon 5D) that I used for my recent Moon photos.

This is my preferred setup for Astrophotography: a Telescope Engineering Company TEC 140 apochromatic refracting telescope on a Astro-Physics 900GTO German Equatorial Mount, A Televue 2" 2x Powermate, and the Imaging Source DMK 31AF03.AS monochrome firewire WebCam.

Here is how I mate the webcam to the telescope focuser. I've opted to use the AP 2.7 adapter on the custom Starlight Instruments 3545 focuser. I then use a short AP extension with an SCT adapter that allows me to attach a Meade electric micro focuser. After that I use a Televue 2" 2x Powermate with Canon T-Ring. The webcam's C-mount is accommodated by a Mogg Adapter that converts the C-Mount to a Canon EOS fitting. This is a very rigid set up. I usually put a 2" filter on the the of the AP 2" nosepiece. Typically, I have to run the 3545 focuser out about 78mm and then a little fine adjustment with the Meade microfocuser is all that remains.

Here is a shot of the setup looking to the West South West. Yes, I still need to balance the setup by moving the counter weight about 2/3 of the way down the shaft.
