Show me yours and I'll show you mine

my 5 inch Achromat (12O mm) refractor!!!!

D=120mm F=1000mm Coated Optics.


THIS IS MY 5 INCH SAXON REFRACTOR.
It is black in colour while my other 4inch refractor is blue.
it is a high quality refractor without breaking the bank!!
It is achromat refractor design which is the same design as the worlds biggest refractor: the yerkes 40 inch refractor built in 1895.
Its objective lens is a Lens doublet (A set of two lenses, one concave and one convex, made from different types of glass. Together the lenses correct both spherical and chromatic aberrations. A single lens alone cannot correct these aberrations)



It is nice to look at and nice to look through.

IT IS ON A 17 YEAR OLD JAPANESE EQUATORIAL MOUNT.It is very solid and sturdy and doesn't shake, rattle and roll.

IT PRODUCES SHARP IMAGES OF THE MOON AND OTHER PLANETS
.
IT HAS ADJUSTABLE PRIMARY OBJECTIVE LENS CELL .
This is my second refractor.I think it is a rebadged skywatcher.They not only rebadge cars but they rebadge telescopes too!
It has motor drive attached(see box attached to mount in photos) but I've never used it.

Stay tuned.More photos coming soon!
