I often shoot the sky with just my camera and tripod and I am thinking about trying an Astrotrac at some point.
I have recently been practicing with just my 400mm f5.6 and attempting to get an image of Andromeda. I realise that I wont get decent detail but I wanted to see what the framing was like.
Whilst I can find it with wider lenses, It was impossible with this one. With wider lenses I can see it with a few seconds exposure, but never naked eye and never through the viewfinder or liveview as it is too dim.
Anyone have any tips for finding objects like this at longer focal lengths? A friend has a 100-400mm f5.6, I suppose that would be easier but I'd rather use my own lens.
