Hello,
M13 from suburbs with small telescope and 181 x 10-second subs.
Three shots of 100 seconds only respectively in R, G, and B for colors.
Traces of coma at left due to the disappointing coma corrector (perhaps inadequate quality control of optics).
Traces of noise due to hard processing.
Anyway pleasant results with minimal effort !
With its 2.4-ยต photosites the camera operates very close to the limits of the optics (diffraction spot, coma, turbulence and so on). Turbulence was somewhat mitigated with the help of 10-s subs. Planetary imaging techniques could give better results in accuracy, at the acceptable price of thousands images rather than tenths.
