Had the Bresser 152mm out for a visual first light session tonight. Collimation check with star test was perfect. Spent some time checking double star splits, the bright nebs in Sagitarius, and the field curvature and CA. The CA is actually not too bad, not that it will matter for narrowband imaging; however it certainly needs a field flattener for imaging. I have an Orion Flattener on order from Bintel, as it seems to best suit the back focus of my camera (55mm to the sensor with the filter wheel in place). Can not really image test until i get the flattener, but things still look positive for this setup to work.
