Alineamos la montura, de manera que vemos mejor.

Yes. Alineamos is the nosotros form of alinear, and this spelling can mean either:

• present indicative: we align / we are aligning
• preterite: we aligned

In this sentence, it is normally understood as present, because the next verb, vemos, is clearly present too, and the whole sentence sounds like a present or general statement.

Because Spanish usually omits subject pronouns when they are not needed. The endings of the verbs already show the subject:

• alineamos = we
• vemos = we

So nosotros would usually only be added for emphasis, contrast, or clarity.

Because montura is a feminine singular noun, so it takes the feminine singular article la.

Spanish articles must agree with the noun in gender and number:

• la montura
• las monturas

Also, the use of la suggests a specific mount/frame already known from the context.

De manera que is a connector that links the first idea to its result or consequence. Here it means something like:

• so
• so that
• with the result that
• in such a way that

So the structure is:

• first action: Alineamos la montura
• result: vemos mejor

Because this sentence expresses a real result, not just a goal or intention.

• vemos = indicative, used for a stated fact/result
• veamos = subjunctive, more likely if you were expressing purpose or something intended

So here, de manera que vemos mejor means the alignment actually leads to better vision.

If you wanted a more purpose-focused idea, Spanish would often prefer something like:

• ...para que veamos mejor

Here mejor works as an adverb, modifying vemos.

It tells you how we see: better.

Spanish uses mejor both as:

• an adjective: una mejor opción
• an adverb: vemos mejor

So in this sentence, it is not describing a noun; it is modifying the verb.

Yes. Spanish often does not use poder when English naturally uses can.

So:

• vemos mejor literally = we see better
• natural English in context may be = we can see better

The idea of improved ability is often understood from the situation itself, without needing a separate verb like podemos.

Yes, it is very normal here.

The comma helps separate the main clause from the clause introduced by de manera que, which expresses the result. In this sentence, the punctuation feels natural and standard:

• Alineamos la montura, de manera que vemos mejor.

You will very often see a comma before this kind of linking expression.
