MTF Analyser - great new tool from Russ Croman - and it's free!
Pretty nifty. Everyone should play around with this tool so they can learn a few things such as:
Why having an EdgeHD 14 might not be the best idea if you live on the coast and;
Drizzling is not the answer to everything!
It also shows why people need to stop using the Dawes or Rayleigh limit at face value for pixel sampling.
The graph from my M106 session. It really shows that while I didn't meet my telescopes theoretical limit by binning x2, I was never getting there anyways and I didn't lose anything by binning. Conversely, I could of done without the slight 1.3X drizzle.
Meanwhile, consider the graph below. Yes there is some under sampling with my FLT91, but Is it really worth drizzling and injecting a tonne of noise just to recover a tiny bit of detail? Probably not.
