Field of view

[Marcus daniel]

Hi all

Please help, I want to be able to take and image of the whole moon rather than sections using my camera, I am putting the neximage directly into the main focuser, how can i effectively zoom our so to speak so i gain the full image. Is this possible

Hello Marcus.

You can get one of these Celestron NexImage Reducer Lens which is effectivly a focal reducer.

I don't know the specs on how much it will reduce it by, so I can't say whether it will give you the hole moon in one image...probably not. Apparently you can stich two togeather if you are good with solder etc.

However a more challenging way but more rewarding is to make a moon mosiac. Check out the Luner imaging section for those and you will see what I mean.

Also have a play with this: http://www.12dstring.me.uk/fov.htm

Just select your scope and camera and then choose different objects and it will match the FOV for you.

HiMichael, Yeh I have a focal reducer already, was using it last night. It still doesn't open the field of view much really. Will have to try mosaics... gulp! will look at the site you recommended too. Thank you for your help.
