[ptx] Some sphericals - looking for feedback what I should improve next

[Mike Runge]

Hello,

ich have done some panoramas indoor (lowlight condition) and I'm looking 
for your feedback:

Pentax *istD + Sigma 8mm MF, 4+2 shots, ISO 400, Apperature was 4, time 
was ~0.3 sec.
I haven't done any noise reduction yet. I'm using Hugin + Gimp and the 
Pentax lab to develop the RAW files.
Any recommendations what tools + techniques to use for doing noise 
reduction? I tried RAW Shooter Essentials, but it's not giving me the 
colours I get the with the Pentax Lab - even if the noise reduction 
would work fine.
Any other feedback, what YOU would improve next?

best, mike
