G'day Rob, it's been awhile.
I guess I'm prejudiced here Rob, but.... I've had the unmodded 300D and just taken possession (and it really is possession, no-one is going to put one greasy dirty little finger mark on my new precious
) of the UV/IR modded 20D and it's great to use. Also with the filter mod it will also still come to focus using standar Canon EF lenses. You can still use it for daylight photos as long as you create a custom white balance. np
Guiding a C9.25 with DSLR on and EQ5 will be a challenge though, as would putting it on an LXD75. I'd suggest getting a smaller scope (ED80/100 etc) to start with. There are plenty of threads around on what's needed to autoguide but basically.
1. Mount with sufficient weight and accuracy tolerances and autoguide capabilities.
2. Webcam or similar
3. Second scope or Off Axis Guider (
)
4. Guide program (PhD Guiding, Guidemaster etc (free))
5. Guider interface between PC and Mount; Shoestring Astronomy - GPUSB
6. Masochistic tendencies.
Where we go from here is up to you
