Newton Telescope Field of view

[JDWolf]

I've just got a book full of star maps for each constellations and i just need to check something.

Say I'm looking for an object that is (on the map) left and up from a bright star, if i then have the bright star in the centre of my Field of view in a newt telescope would it be to the right and up from the star or right and down from the star? I.e. is it mirrored or inverted or something else?

I'm a little confused about which way to move the scope :?

Down and right with the newt Jon provided you're not using a barlow.

It's easier to rotate the map JD.

South is usually marked on Starmaps (usually at the top to confuse you)

[JDWolf]

ok so down and right its.....so what is it if your using a barlow? is it left and down or left and up?

thansk for all your help.

[MartinB]

Up and right. It puts the image the right way up but still mirrored - like a star diagonal.

South is usually marked on Starmaps (usually at the top to confuse you)

That's so you can look at them upside down Gordon...

Thanks for the info

I suspect it matters also which side of the Newt. the focusser is on, as you are standing the other way round if you are at the other side of it. With a Dob. mount you can point it straight up and get all the lefts and rights you want.

CC is exactly right, once again. Which side the focuser is on has a LOT to do with how you perceive the image. When faced with this choice, I move the scope according to the chart, up and left, and ignore the view. Watch the STAR PATTERNS, not the direction from which they appear.
