Hi Ray,
Can you help with data foe the kaf8300 that a lot of us use.
Once calculated, you mention we should aim at exposures that give us a background with this value. But that implies a few trial subs.
Isnt it easier to take on 3 min sub and use the online calculators.
I get 1800 in 3 minute L even with an LP filter, thats how bad my LP is and the online calculators always given me figures like 90 or 120secs.
However ive seen a marked difference with 5, 10 min subs.
So if I go by your calc or the online calc values, get lots of smaller subs, will that be better in terms of getting details
Thanks
Alistair
