DSLR focus for wide field astrophotography
Hi all
How do people go about ensuring a good focus on their DSLR for widefield work? In my case, I have a Canon 450D (with liveview) I would like to use to try some widefields using the 25-55mm kit lens that it came with. This is widefield milky way stuff I have in mind, so the moon won't be around to tweak focus on.
I imagine I'll just have to snap off short shorts and keep checking them on the larger laptop screen? I don't really want to by an angle finder magnifier for the odd shot I expect to be doing.
Any info appreciated,
Rob
