OK, Paul, might be worth a go. The DBKxx series seem popular but have lower resolution that the Meade, both use Sony CCD sensors. Yes, I know I will have to get an EQ mount for any serious work. Luner is fine with the 6SE as exposure time is short. Have tried Saturn but with Prime focus on my Olympus E500, the image is too small and extremely difficult to focus, even more so if I use projection techniques for which ony narrow diameter eyepieces will fit. Part problem is no live view and the viewfinder, although TLR, is small (4/3 sys) and even though I have a 1.5x mag attachement for the viewfinder, it is still too small an image to properly focus. The E500 has a f4.5 150mm lens which is comparable to a 35mm 300. I have seen Canon and Nikon300mm shots that are fabulous. I doubt the Olympus can hold up owing to smaller sensor and greater noise. But without an EQ motorised mount, I can't even begin to think of DSO with it.
Lastly, Paul, re CCD cams. I note that in solar photos that the mag is very high, eg saturn etc. How is this achieved if through prime focus, can it be varied with length of extension tubes etc. and, do these cams come with filter threads? I note that the new Meade III (too expensive) has a filter holder.
Sorry to be such a pain, but need to learn.
