With regards to the focal length issue, what is the concensus of using something like a 1.5 or 2 X converter between the camera and the T mount as one would do with a normal camera lens or have I lost the plot? This way you could use the ED80 and if getting closer was a requirement, the converter would pump up the magnification. Albeit reducing the amount of light comming in but could this not be catered for by longer exposure?
