How about a professional acquaintance to help me take a look at this telescope

The introduction of this product seems to be a little weird.,Although I can't see the hard injury.,But it always feels wrong.,Can you send me the link address to see? You can send me a short message. I'll take a look at it for you.

Because this specification feels very strange, it is not a common specification in the industry, and the field of vision and specifications are also a bit mismatched, so it is not ruled out that there may be elements of random labeling, so I want to link with you to see.

Moreover, the introduction of this product itself has some moisture ingredients, such as:

Resolution: Storage temperature: -55 +70

Operating temperature: -40 +55

Therefore, it cannot be ruled out that it will be a random bid.

Just by looking at the ones you quote, you can't be sure of how the product is, so if you want to be sure, just send a link to see it, you can do it in a short message.

The caliber is large, and it is inconvenient to operate, so it is better to choose about 40. Personally, I think Tasco's is not bad, so check it out for yourself

The two mirrors are poorly comparable, and they are suitable for different observation targets, and the difference is also very large.

The former is a short-throw ordinary achromatic refractor, with a focal ratio of f 6, an aperture of 102mm, and an equatorial frame, which is more suitable for observing celestial objects with a large field of view at low magnification. Under such operating conditions, the image is bright and high-contrast, but there are certainly perceptible chromatic and other aberrations that increase with system magnification.

The latter is a telephoto small-aperture entry-level Newtonian mirror, the data in the focal ratio ** is wrong), the diameter is 76mm, equipped with a flat frame, which is more suitable for observing planets and lunar surfaces with higher magnification. Due to the use of the reflected light path, it has no chromatic aberration problem, and other aberrations are also controlled due to their lower magnification, but the smaller aperture limits its usable magnification. The ** of this mirror will be much lower than the former.

To sum up, there is no absolute "good" and "bad" thing about telescopes - of course, there are really "good", but **too extravagant-what suits you is the best. The one you choose according to your needs is the one that suits you best.
