- Afocal Astrophotography Experiment. January 25, 2021. The Grand Conjunction of Jupiter and Saturn on Dec 21, 2020 was a chance to experiment with a new (at least to me) astrophotography technique: afocal imaging with a smartphone camera. Most astrophotos you see in Sky Lights were taken with my Canon 20D, using either a telephoto or wide angle lens, or …

- Afocal astrophotography Taking your point-and-shoot camera (an example is a Canon Powershot SX720 ) and pointing it into a telescope eyepiece is known as the afocal astrophotography method. You simply line the camera lens up with the opening of the eyepiece and try to capture the view seen through the telescope at that magnification.

- Afocal What? Unless you’re old enough to have learned astrophotography from the Sam Brown booklets (above) that Edmund Scientific sold for less than a dollar during the 1960s, chances are you haven’t had much experience with afocal photography and may not even be familiar with the term. Nevertheless, every clear night amateurs with digital ...

- With afocal, your ~effective f#~ is your NV lens focal length divided by the size of the exit pupil emerging from the telescope (and is independent of the spacing twixt scope and NV). e.g. if your NV has a 1-inch (25mm) lens, and your scope+eyep combo has a 6mm exit pupil (traditional "rich field" mag at 4x per inch of aperture)... then, in this example, your NV will be …

- Afocal astrophotography uses an eyepiece on the telescope. The camera (with its lens) looks at what the eyepiece "sees", just like your eye. Magnification can be greater than when doing prime focus imaging, but as magnification is increased the object becomes dimmer (requiring longer exposures and/or higher ISO values) and accurate tracking/guiding will become more important.
Imaging Setups for Astrophotography
- https://astropix.com/html/astrophotography/imaging_setups.html
- An Afocal Setup This setup consists of a telescope with an eyepiece focused at infinity, combined with a camera with the lens on it, also focused on infinity. The camera is held up to the eyepiece and the photograph is made.
Afocal vs Projection vs Prime Focus - Stargazers Lounge

- Not quite. Afocal imaging - an image taken through an eyepiece using a camera with a lens. Eyepiece projection - an image taken through an eyepiece with the camera body attached directly to the eyepiece - no camera lens attached. Prime focus - camera body attached directly to the telescope - the telescope lens effectively becomes the camera's lens.
