However, looking at the spec for the scope now on the european tak site, they have removed all the image circle data?
Looking at the fs60 on opt, they say the factory in Japan was damaged in the disaster over there and production is currently halted. |
it should have no problem illuminating the DSLR sensor then. We were wondering whether the that was the reason my flattener is failing to flatten - but obviously not. I also tried Ricks flattener (same one) to see whether it was my unit - but same thing with that one. The only thing it can be is that the sensor distance is too great - but mine and Peters measurements show that it is only over by about 1mm. I have tried
increasing it a few mm without any great change, but I'm buggered if I know how I can decrease it....?

didn't get to take any flats though....but I am reasonably happy with it . Thought it might be a little sharper/more detail - but I think my focus was just a hair off - I really do need a fine-focus knob for it.
It would have been nice to get another few hours on a different target last night - but right now I am glad for the few hours sleep I did get.
Did you get those weights for Paul...? You hadn't surfaced by the time I left
