Hi Stefan,

Thank you for the reply and also to those who have replied privately.

I have taken a look the high resolution version and though I agree  
that this is a better option to go, cost is unfortunately prohibitive  
at this time.  Anyhow will still re-evaluate the options and perhaps  
in a long run this would better, since I have intention to work EME in  
the future.
