M27 RGB Sythesized from 7nm Ha 3nm Oiii
Slow in gathing good data, only around 30% acceptable frame rate. The image is a synthetic RGB
based on an Hbeta/Halpha ratio of 30%. Weights of the Ha and Oiii are given appropriate weights
that correspond to their RGB metameric contribution based on their emmision frequency.

Gernerally not bad for the amount of data, 6 hours per channel at f11 is not really that much.
Also not particually helping is that I decided to go unbinned on this which is another factor of 4
compared to my norm. Anyway, it is what it is :)
