I am testing an L-extreme filter with my QHY268C. I am amazed by the download speed and overall camera management in Voyager, impressive.
The L-extreme with this camera works nicely on my FSQ106 @ f/3. I read some reports and tests that show that the L-extreme drops transmission with fast optics, according to the document at f3 on 25% of the Ha is transmitted. I have ordered an IDAS NBX filter that is better suited for fast optics. Nevertheless, I am somehow impressed with the results and the quality of this new generation CMOS sensor.
200x5min with the L-extreme, FSQ106F3 and QHY268.
