Photographic zenith tube

Since we are concerned about receiving SLR, we recommend three models:

1, Sirius 80 painter.

2、DIY 102/600。

3. Star Trang 80EQ.

These models have their own merits:

1, Sirius 80 painter's caliber is 80mm, focal length is 600mm, 2-inch toothless focusing base with scale, convenient for shooting and focusing, more convenient for carrying, and equipped with portable soft bag; This telescope has a good reputation in astronomy, and the price is 1200 ~ 1400 yuan. Relatively speaking, the cost performance is not very high.

2, DIY means do it yourself, 102/600 means aperture 102mm, focal length 600 mm, there are two models, one is a 2-inch toothless focusing base, 898 yuan, and the other is a 2-inch rack focusing base, 758 yuan; This model has the advantage of caliber. Compared with OTA with the same caliber, it is cost-effective, but the key depends on your own hands-on ability.

3. Startron 80EQ has the most advantage in price, and the whole set is very neat. The main mirror, equatorial telescope, tripod, eyepiece and zenith mirror can be said to be the most suitable for entry. The focusing base has M42×0.75 thread, which can be directly connected to SLR, and the focusing stroke is long enough to focus easily, basically without buying other accessories; But this model has a diameter of 80mm, a focal length of 900mm and a lens barrel length of about 1 m. The equatorial telescope is also the simplest, and the two eyepieces-K20mm and K4mm are the most common, of which K4mm is basically not used, and the second model is only suitable for beginners.

Of course, the above three models are all popular and catadioptric, and color difference is inevitable. If you want to use a better one, you can consider the ED telescope. If you only look at astronomy, you can also use a large-caliber bull's-eye telescope.
