The luminaire can be used not only with the Celestron Astromaster telescopes, but also - after some modifications - with telescopes from the Synta factory with a diameter of 90 mm (Sky-Watcher, Spinor, Pentaflex and others). To fit the luminaire, plastic inserts should be thinned around the perimeter. To do this, lightly and carefully trim them with a sharp knife, checking as you progress, if the fitting already fits. Due to the use of a knife, special care should be taken not to allow injury.
On request, we can do this adjustment in our range - when ordering a product, please write a comment that the fitting will be used with a telescope from the Synta factory.
