Here is the place to talk about all those equipment(Telescope, Mounts, Eyepieces, etc...) you have. Not sure which scope/eyepiece is best for you? Trash it out here!
1) DSLR or CCD which can process in more easier , reasonable price and quality picture . budget < S$2000.00
Processing of image is basically the same for both. But I think DSLR will give you higher resolution image at a lower cost.
Depends on what kind of CCD camera we are talking about. 1 shot color or mono? If comparing a mono CCD camera to a DSLR, the mono will give you more resolution even if pixel and sensor size are the same because of the bayer filter in the DSLR. To get the same level of resolution, you will have to dither then debayer the color image. Or dither and convert each image to greyscale. The CCD will also have less noise due to being cooled thus increasing sensitivity. Sensors in DSLR also have a lower QE then dedicated astro CCDs.
For CCD's, you can also mount a camera lens and take wide field.
See Mogg's website for examples.
Essentially now CCD's like ATIK and Orion Startshoot mono is generally cheaper than DSLR and you have 4 times more resolution. (I am not talking about FOV)
In short, the choice boils down to how "hardcore" are you.If you are thirsty for resolution, get mono CCDs and if you want nice colour pics quickly, get DSLR.

u can do that with a DSLR.
Actually you can. With the certain adapters, you can use many different lens including large format lens (eg Pentax 6X7).
plus a DSLR, negates a need for a laptop. with a dslr u can straight away make controls and adjustments
Well it depends on whether you want to use a computerised focuser program (eg DSLRFocus) or use certain programs to control the camera (eg Maxim DL) or use a planetarium program to control the mount (eg The Sky 6). All these need a computer.
I agree that. Actually carrying a laptop is not much of a chore when you compare it to the LX 200. Focusing and running a sequence of DSLR images using software is fast and easy. You don't break your neck as well. hehe.
Besides, if you need autoguiding, then you will need the software to run it also. If you want to use independent autoguider, its fine also. Personally, I prefer an integrated system, slew to object, calibrate the autoguider, then take a sequence of exposures all from the laptop. After that, go to sleep for 45mins.
What I like about DSLR is that it is self-contained. No need to pull power cables, and if the laptop runs out of battery, I can still happily continue taking pictures - which SBIG cannot do (yet). Furthermore, during the day, I can take photos of scenery, etc..

I agree that , it's not easy for me if i want to bring the LX200 8inch , notebook and etc to do outside astrophotograph . but ....i worry with my OTA forkmount after connected with the T-adaptor , microfocuser and the camera body , it will increase the length of the back , if the objects showing at vertical more than +45 degree , the camera body will hit the computer control panel on bottom, it may damage the telescope and camera . :|
