The accessories are just disappointing. If the accessories were just decent, I would easily recommend this telescope. But they are not. They are complete garbage and useless.
The 4mm eyepiece is just frustrating to use. Its eye relief is too short, and the lens is too small. You won’t get any kind of decent image out of this eyepiece.
The 3x Barlow is not a “real” 3x Barlow. It is just some glass that has been fitted inside a plastic tube. It is clear that Celestron sends this just to make this telescope seem more powerful. In reality, a legitimate 3x Barlow is extremely hard to make. (The accessories are infuriatingly bad.)
I don’t know why most companies still send 5×24 finders. They are not helpful by any means. Same as the 3x Barlow, the lenses are low quality and extremely small. A simple, red dot finder without any magnification would be much better.
The diagonal is intended for terrestrial viewing, and it does its job. It lowers the image quality quite a bit for astronomy.
Overall the accessories are just dreadful. This part is the deal-breaker for PowerSeeker 70.
