Try with a 45cm telescope

Try with a 45cm telescope.
Recent back-illuminated CMOS color cameras (Neptune-C II) have high sensitivity in the infrared region, and the RGB color balance is lost. However, the sensitivity is high. When examined with 45 cm + 15 seconds exposure (gain 400, 360 sheets), a star with m = 20.91 was confirmed. Is it a benefit of high infrared sensitivity?
If its good seeing and transparency, optical axis of the telescope, and tracking are improved, it will be possible to capture the target 21 etc.
