Description

Mach2GTO first light.

Polar aligned by NINA three point polar alignment plug in. Alignment error, according to NINA was within 1 arc minute in total. Took 36 5-minute frames, unguided. Tossed one due to target behind trees. All other frames were good. There was a tiny tilt of the sensor and the spacing was a little bit short. The corner had slightly elongated stars away from center. But center region were perfect round ones. No dark frames. Not flat frames.

Very basic processing. WBP preprocessed to cosmetic correct, align, and integrated. Automatic background extraction and followed by SPCC. EZ suite noise reduction, soft stretch, and star reduction.
