Delivery was very fast ! I am very impressed by this FPL 51 ED doublet, the images are sharp and the CA is very well managed. For the money, this has got to be one of the best bank for buck out there. The focuser is very smooth with this micro adjustment knob it is definitely better than my old 5 inch MAK. Really enjoying the scope so far. I pushed it to 360x magnification during the day and it performed really well, felt like a microscope on a tree that i tested. Now i need clear skies for more testing at night.
