The rack-and-pinion focuser is plastic on the outside and metal on the inside. I appreciate this decision if it decreases the cost.
The eyepieces are boring Kellner models. They are as budget as it gets. I suggest replacing them as soon as you can. A 25mm Plössl is a decent starting point.
The star diagonal is ideal for astronomy. In contrast to the usual “Amici” models, Star Diagonals don’t decrease image quality. Like the 2″ Focuser, it is a smart accessory to send with a telescope.
The finder is a red dot model. It is also a cheap choice like the eyepieces, but you will only use them when first aligning the telescope. So this is not a huge deal.
