a customer here in germany wanted to buy it, but good health problems due transporting his heavy mount in and out, so he have had to pass on the confirme dpurchase.

Due that the sale is up for sale again. The lens of this big and very fast apo is above 97 %

TMB-Apo 203mm/1420mm CNC-LW II Model Matthias Wirth Version.
The TMB 203mm f/7 Apo is our new large imaging machine. Soon a matched field flattener for up to 6x7cm film format will follow. TMB Optical again did a superlative job in designing this large color free Apo, even given the challenge of its very fast speed. LZOS did a stunning job implementing this lens within these design parameters. The image quality and color correction of this new fast model are so exceptional that you can utilize similar visual magnification as with our famous f/9 model. We recently had a wonderful first light experience with this new model. Mars was pushed up to 500x with great sharpness and contrast. The Veil Nebula was viewed with great detail under moderately light polluted sky without any nebula filter, all thanks to the great contrast. The tube rings are flat on both sides and offer five tapped 1/4-20 inch holes perpendicular to the tube line with one centered. The middle two hole's center to center spacing is 60mm (2.362") and outer two hole's spacing is 3.2" (Astro-Physics standard) This Matthias Wirth model is even lighter in weight than our CNC-LW II model. The decrease in weight was made from the focuser side, and results in a very front heavy tube. It is, however, an exceptionally transportable 8" f/7 TMB Apo
