I can currently Helpful Review that after a correction would reign with PTLens an acceptable increase in the FOV, disagree. It is merely minimal, but the loss of quality (chromatic aberration and loss of detail) is clear. Two stars from me there is only because it is now times this minimum FOV profit. But by the loss of quality, it is that I find no more worthy, in particular because of the additional workload which each photo is created by the necessary equalization.
