Comparison
The Celestron CGEM II 1100 is the clear winner for serious amateur astronomers. With an overall score of 79 versus 46, this telescope outperforms the Advanced VX 7" Mak across nearly every category that matters. The single most important differentiator is aperture; the CGEM II's 11-inch mirror gathers significantly more light than the 7-inch Mak, delivering superior detail on planets and faint deep-sky objects.
The Advanced VX 7" Mak suits budget-conscious beginners willing to sacrifice performance for a lower entry price and marginally better portability, though even at $2499 its beginner score of 35 suggests a steep learning curve. The CGEM II 1100 belongs in the hands of dedicated observers ready to commit to planetary observation and deep-sky exploration, where its 77 and 65 scores respectively demonstrate true capability. Despite the $1500 premium and heavier weight, the CGEM II delivers substantially better optics, mount stability, and versatility.
If you're serious about amateur astronomy and can manage the equipment, the extra investment returns measurable results.
