Making A Refractor Telescope Norman Remer Pdf 12 New File

Making a refractor telescope is often seen as a daunting task compared to building reflectors, but Norman Remer’s seminal book,

: A mirror surface must be figured four times as accurately as a lens surface to achieve the same wavefront quality. This makes manual lens grinding more forgiving than many realize.

Grinding a lens doublet requires working on (two for the crown, two for the flint), compared to just one surface for a standard reflector mirror. making a refractor telescope norman remer pdf 12 new

While a classic, small-aperture starter telescope might use a modest 60mm lens configuration, custom ATMs often scale up to larger, custom dimensions like a or a 6-inch (152mm) f/15 configuration .
