When calculating angular resolution, is it correct that having a SMALLER number results in GREATER angular resolution? For example, is 26.25" better resolution than 2625"?(adsbygoogle = window.adsbygoogle || []).push({});

Using the formula .25"(lambda in micrometre/diamter in meters), it would make sense to me that the larger the diameter, the smaller the answer, thus the greater the resolution. I just want to be sure I understand this correctly.

Also, out of curiosity, why are we multiplying by .25"? This is the formula my book gives me...but is this always a constant for this formula?

Thanks!
