Hi Michael.

I really only know enough to be dangerous, but have had some success with following:

- Locate object using GOTO + camera viewfinder and/or finder (for very tough object perhaps with eyepiece in first)
- Rotate camera until object framed suitably
- Takes some 30sec ISO 1600 test frames to check framing
- Save position in GOTO as user defined #1
- Slew to a bright star
- Use Liveview to focus (I have a newt, so I get nice diffraction spikes when at focus on a bright star)
- Lock focus
- Slew back to user defined position
- If guiding, use guidescope to find a guidestarr, then get PHD or other program calibrated and locked-on
- check camera still on target
- start taking subs (perhaps ISO 800 for 3mins as a starting point if unsure and have light pollution)

I tend to leave in camera noise reduction on and take flats with a homemade lightbox at the end.

Hope that's not too much waffle.....!
