Lunar Imaging With DSLR

Guys,

Can anyone give me a start point on dslr settings for Lunar imaging please? I just got an astro modified Canon 100d, put it on the tripod tonight with a 80-210mm lens but I couldn't get it to focus. I tried all the different modes including manual, different F settings and shutter speeds, manual focussing too but still couldn't get focus.

Can anyone give me some pointers as a good starting point/camera settings etc? This is new to me so I know I have a lot to learn, stupid thing is in daylight I have always been good with a camera but of course this sort of photography is a whole different ball game and I find it quite frustrating :o(

Cheers in advance.

Andy.

You're right ANdy the stupid thing is in sunlight unfortunately :lol:

Is your lens auto focus ? If you set your focus point to just the central dot then it should auto focus on the moon, then turn it to manual focus or it will just start to hunt as soon as you start to take a photo.

The exposure shouldn't be dissimilar to a terrestrial pic you take but Av won't work. set it to manual and start with 1/250th at f8. Your image scale won't be very big even at 200mm so zoon into your image to check focus and exposure and change settings if necessary.

post your results for us to see.

Hi David,

This is all done in 'live view'? How do I set the central dot as you explained, can I not just focus manually to start with. You're right, the autofocus just hunts continuously and it can't take the image.

Didn't think the 100D had live view, I don't think that's the best way to focus on the moon.
Look in your manual it will tell you how to select the centre focus dot.
You could focus manually but why do that when the auto focus will work and it will be spot on?

If you're still there pop onto chat

You said above to take it off of auto focus as it hunts all the time, which it does? Yes, it has live view, been reading posts saying it's the best way to focus but maybe this isn't the case then?

correct.

If you are focussing on stars then live view is the way to go because auto focus won't work, when you use live view for focussing on stars you zoom in with digital zoom in order to focus and get the star as small as possible.
