Xinda Xiaohei can be used both as an entry point and as an advanced magic mirror, as it also has full upgrade potential.
In terms of type, Xinda Xiaohei belongs to the Newtonian reflex of bull herring. As I said before, Niu Anti is suitable for deep space photography and astronomical observation and shooting.
Its aperture is 150mm, which is relatively large at this price, with a focal length of 750mm, an equatorial mount for the EQ3, and an aluminum alloy tripod.
Xinda Xiaohei, many friends use it for photography, it can be said that Xinda Xiaohei is a sharp tool for deep space photography, and the effect is very good.
To put it simply, Xinda Xiaohei is divided into a normal version and a photographic version.
The single speed is the normal version, and the double speed is the photography version, the difference is that the two speeds have an extra fine adjustment knob, which can be adjusted more easily.
1. One turn of coarse adjustment is equivalent to 10 turns of fine adjustment, so the double speed can be more accurate.
2. Double-speed version, after connecting to the SLR camera, it can focus faster and facilitate photography.
Dual-speed and single-speed, the picture you see is the same, it's just that in terms of focusing and focusing, it's a little easier with dual speed, and the other differences are not big, because the primary mirror is the same .
If you are a novice, or the budget is not much, you can buy a single-speed first, which is enough for daily use, and then buy two-speed accessories when you are proficient;If you have enough budget, you can buy a two-speed one directly.
In short, Xinda Xiaohei is an advanced mirror that I highly recommend.
