M/S: MKH 50/20 with MKH30 combo > How to line up diaphragms ?

Hi everyone,

First of all i am not really a bird recordist (at least not yet), but i am =
learning a lot here about recording and listening. Great stuff!

I am a sound designer with a passion, recording my own sounds.
Main interests are ambiences (urban and natural) and sfx. I usually record =
with my MKH50 and a pair of DPA 4060's (matched) and my trusty SQN4s2 and a=
 AIWA DAT. But i wanted to expand my mic horizons and try something new.
So this weekend i bought a second hand MKH30 together with a MKH20 (matched=
 pair).I feel very lucky, the mic's were cheap(!) and the 30 sounds amazing=
, i only tested it with my MKH 50.

However i am not really sure how exact i should line up the diaphragms. Is =
there some kind of rule i am supposed to follow or is the kind of thing whe=
re you experiment and learn (rule of thumb).

Anyone any ideas or links?

Thanks in advance!

Greetings,

Arnoud
