Today's larger imaging sensors require more light, and with the Alpine Astronomical Baader M54 Extension Tube, you get it. Unlike the smaller, more common T-2 size, the larger M48 provides significantly more light throughput, and its 10mm optical length allows you to adjust the working distance to put the focal point exactly where you want it. You can use this tube by itself or stacked with other tubes. The tube is made of anodized aluminum and outfitted with machined external (male) threads on one side and internal (female) threads on the other.
