Here's an image of this morning's conjunction taken from Brisbane. I decided to zoom in a bit (using the 70-300mm telephoto at 70mm) to try and capture some detail in the Earthshine. I hope you like the result.
There's also a shot of Comet Lulin approaching Saturn, taken about 20 minutes earlier using the same lens. It was a great way to start the week, with comet and conjunction!
Nicely captured! You suffered the same as mine, that the longer focal length views have some trailing in them. They really need to be piggy backed and tracked.
For this shot I was using a 70-300mm telephoto at 70mm, but you will be able to use 300mm tonight (as I did in the newer thread started this morning) because the comet is closer to Saturn. Exposure times etc depend a bit on the camera, but I would try a range of about 6-20 sec with the aperture fully open (e.g. f/4.5-5.6), and sensitivity set at 1600 iso or thereabouts. Just try a few shots with these settings in mind and adjust as you go along.
