Subject: questions about sharpening before/ while stacking and IR pass filter


Hi Folks,


Well, the holiday and some brief periods of fair seeing has given me a

chance to try out the DMK camera with IIDC.  I like the setup and it should

work well in the future :).


I wanted to ask about sharpening before or while stacking.  There are

various degrees of sharpening, including noise reduction, available in IIDC.

The manual shows the differences.  I was wondering if anyone else regularly

uses this presharpening and what benefits does it have?


Also, the IR-780 IR pass Schuler filter definitely didn't seem to be the

right choice.  It significantly dimmed targets over any of my other filters,

including blue.  Therefore, I'm going to exchange or return it if I can find

out the correct spectrum of the filter I need.  Anyone know which IR pass

range or filter offers the best transmission? (Alan, I must have been wrong

in assuming you had the Schuler IR-78)


Thanks,

Eric
