The narrow field-view makes it a little hard to see deep space objects as a whole. We don’t recommend this telescope for deep-space observation. A Zhumell Z130 would be much better in that area.
The optics are not collimatable. This might seem like a big problem but a Maksutov-Cassegrain optical design won’t need collimation other than extreme cases. Even if you drop your telescope from a high place or hit it with something, the optics won’t get misaligned. Therefore the “not collimatable” aspect actually saves you from dreadful minutes spent on aligning the optics.
The eyepieces that come with the telescope are surprisingly good for this price range. A 25mm(50mm) and a 10mm(125x) Kellner is more than adequate for the beginning. Of course, getting a more expensive eyepiece such as a Plössl would give you a much better observation experience.
