Thanks Guys,
Yes Gary, it works fine as I use it to capture planets like Jupiter and Saturn and I can turn up the gain on it and pick up faint moons orbiting both of these as I have seen these when focusing with the dob.
It seems I should be OK from all your responses, however, another thread I read put me onto the fact that I may have to shorten the FL of the guide scope (F7.7) by using my 0.5 focal reducer to be able to provide a wider field to pickup more stars?
I think the main thing was whether I needed to engage the long exposure mod to enable longer exposures to be able to expose the fainter stars, but I might just have to try it out and fiddle with the settings to see how I go. Like I said, I think the focal reducer may come in handy also.
Sound like a plan?
Cheers
Chris
