SM40/BF10/DMK31AF03, seeing 5/10, transparency 8/10, very nice sky that I seldom met!
Taken on 1504: 2x barlows + 2.5x corrector with extension tube, around 4x effectively, oversampling indeed.
Taken on 1506: 2x barlows, the same QRF but at proper sampling.
This is a mosaic of 3x3 raw frames, it maximizes the resolution of Solarmax 40 theoretically.
Finally, a CaK taken on 1512.
