![]() ![]() ![]() The included red dot finder is of course adequate for aiming the Z130 thanks to its wide field of view, and is easy to align and understand how to use. ![]() At f/5, these eyepieces work pretty well and won’t have too many issues towards the edge of the field of view, though they still suffer from the glare problems inherent in the Kellner design and are a bit uncomfortable to use. In this case, the eyepieces are a 25mm (26x) and a 10mm (65x), and all-metal in construction, albeit lacking rubber eye cups. Like the other Zhumell tabletops, the Z130 includes two Kellner eyepieces and a red dot finder. If for some reason you decide you want to use your Z130 on an equatorial or alt-azimuth mount and tripod, this is a huge boon that will save a lot of effort and expense. The Z130’s optical tube attaches to its mount with a pair of tube rings and a Vixen-style dovetail – an arguably overkill arrangement that allows you to not only rotate and slide the tube to balance it and position the eyepiece, but also means you can stick it on almost any other telescope mount with no additional tools or hardware. The Zhumell Z130 has the same 1.25” plastic rack-and-pinion focuser found on many beginner scopes, which may require some shimming and lubricant to work well but is perfectly adequate. The bad news is that it requires tools, stripping the screws in the field may ruin your night if you aren’t near a hardware store that has late hours, and learning how to finely adjust it takes a little more practice. The good news about this arrangement is that it holds collimation really well, and you probably won’t have to adjust it very often. To collimate the Z130, you have to remove a useless metal back plate with a screwdriver (purely cosmetic, you can throw it away) and then adjust 3 pairs of push-pull screws, also with a screwdriver, which tend to easily strip. ![]() The Z130, however, is one of the 130mm f/5 variants that for whatever reason has a simpler mirror cell based on old-fashioned Japanese-made reflectors. This optical configuration is fairly common and available from a broad range of brands on a variety of mountings ranging from tabletop Dobsonians like the Z114, to equatorial mounts, to computerized GoTo rigs. You can get a glimpse of its moons as well.The Zhumell Z130 is a 130mm f/5 Newtonian reflector with a focal length of 650mm. The white stains are the ice caps, and the black-red colors are due to the nature of the surface. Mars will show a significant amount of surface detail as red, black, and white stains. Its many moons will appear, and its largest moon Titan will show itself as a disk. There will be some stripes around the planet, and the yellowish color of the planet will appear. Rings of Saturn will show its separate lines, with Cassini Division easily observable in the middle. The color accuracy you will get will be on-point, with gorgeous shades of beige, yellow, red, and brown. Jupiter’s many stripes, The Great Red Spot, and its 4 Galilean Moon’s will be crystal clear. The moons will appear as spheres instead of bright disks. I will assume a decent planetary eyepiece in this section, but with the 9mm eyepiece, expect half of the performance I will write below. With a decent planetary eyepiece such as a Goldline, you get an insane planetary performance with Z12. It is nowhere near enough for a telescope this size. This is due to the low-quality, 9mm Plössl eyepiece. You won’t get the planetary performance Z12 is able to provide out of the box. ![]()
