2" ultralow profilfocuser with 2" slighttube backfocus : 60 mm, enough for CCD and visual use
This is the smallest version of our Maksutov Newtonian serial production. With its diameter of 127 mm and the small centralobstruction its an fair competitor to medium quality 4" ED apos, for planetary and deep sky observing work.The focuser is an 2" Ultralowprofilfocuser with 2" slighttube.
With the short focallenght of 762 mm you can get with 2" eyepieces an ~3,6° field of view. The OTA comes with an nice tubeholder, piggy back camera mount and an 6x30 Finder (optional 8x50 available). The optics are coated/multicoated.
The Vixen great polaris mount is an excellent fit to keep this small powerbaby fully transportable.
