Sv503 is a great refractor for a great price.

This is a great refractor for a great price! I'm an astro-photographer and I've had mine for almost two months. I still get excited about using it! The quality is comparable to the best on the market. The look is almost identical to that of the Williams Optics Zenithstar. Pictures don't do it justice. You can feel the quality in your hands. From the eggshell finish to the gold accents. Solid body, check. Extendable dew shield, check. Tight dual focuser, check. Quality FPL-51 glass, check. Portability, check. This quality at this price, well, worth every penny.
