First test series with the HyperStar. Checked collimation, the ability to shoot with the L-eNhance filter, and overall work with the prime-focus astrograph.

The HyperStar in the zero position required almost no additional collimation; minor tracking errors were later corrected with the BXT plugin in PixInsight.

The filter showed that it works poorly with the narrow hydrogen band; specialized narrowband filters are needed.

Flats could not be taken, and shooting in the city under a full Moon resulted in gradients and vignetting that could not be fully removed during processing.

Overall, I am satisfied with the first test, and we will continue further.
