Feature:
1. The new QUATTRO-150P with it's fast f/4 focal ratio has been specially designed for high quality astrophotography with short exposure times and is also a fine telescope for visual observations. 
2. Supplied complete with it's own bespoke, optically matched  M48 Aplanatic Super Coma Corrector comprising four lens elements including one ED element, that shortens the focal ratio to f/3.45.
3. Supplied with the same Linear Power Focuser as the other models in the Quattro range, which utilises four precision ball bearings to support the drawtube and provide great stability and zero image shift while supporting a heavy eyepiece or camera. Moving the drawtube by the roller rather than a rack and pinion ensures exceptionally smooth operation, great feel and precise adjustability. The dual-speed feature has a second focus knob that has a 10:1 speed reduction to provide the super-fine adjustments even the most demanding users can appreciate.
