Exposure for AP


Recommended Posts

If you have a good steady hand...

You will have to make sure you put the camera to the eyepiece on the exact same orientation relative to the moving scope or you will get star trails and a blurry centerpiece when you combine them.

there are a couple of ways to capture A-focal

the most simple is, mounting your camera to a tripod.

then adjusting tripod and camera over the eyepiece.

long exposures will not work, but for snapping planets,

it should be fine.

second most simple method is using a camera mount,

this fits onto the telescope focuser (usually), and holds

the camera over/near the eyepiece. it also allows you to

move camera forward or backwards on mounting system.

third is usually for DSLR, this involves removing the camera lens,

and replacing it with an adapter holding a eyepiece ( usually 25mm ep's).

this adapter holding the EP and camera then fits into focuser. the eyepiece

then acts like a lens.

the first method no long exposure, the second method could do long exposure. the third could to if the scopes mount is motor driven.

webcam wise, you could do A-focal. you would need to make a tube that will house the webcam, but also let it slip over an eyepiece while fitted in focuser.

it would need to be a very good low lux seeing webcam to.
