    Madison X. ★★★★★

    The f/4 focal ratio captures enough light in 30-second subs to bring out faint nebulae that my slower scope missed entirely. The OTA is compact enough for my mount to handle without extra counterweights, which makes setup faster.

    Stella ★★★★★

    Swapped from my old f/10 SCT and the difference in imaging speed is night and day. The fast f/4 focal ratio lets me capture faint nebula detail in exposures half as long.

    Isabella Z. ★★★★★

    The 2" focuser holds my DSLR dead steady, and the fast f/4 speed means I'm pulling in faint nebulae in under two-minute exposures. Setup took me about 20 minutes out of the box, and the collimation held up through a full night of imaging.
