What is the main purpose of a field flattener and is it necessary?
A field flattener is generally used to clear out the distortions and halation during observations. When you place the flattener properly in-between the Esprit 100 refractor and a camera, you would see sharp images. It evens out the field and provides a wide aperture.
What is the benefit of a precision thread?
The precision thread aligns the lens groups (doublet and triplet) on the optical axis and ensures that they are perpendicular to the image. This makes sure that you always get a sharp and clear view.
Where is this field flattener attached?
The Sky-Watcher flattener is installed in the middle of the Esprit 100 refractor and a camera.
Can it be used with a DSLR?
This is specially designed for DSLR and CCD imaging purposes.
What is the refractor’s imaging circle when used with the Sky-Watcher M48?
The imaging circle is 40 mm when used with the M48 field flattener.
