IC443 Jellyfish Nebula

IC443 R:G:B SII:HA:OIII 260:280:340 20mins sub
This one only reached 35° maximum altitude from my location. I continued to track it as low as 25° but it just wasn't worth it with current conditions. So, this is a stack of what could be salvaged.

Focal Length = 1600mm (RC8)
Image Scale 0.7 arcsec/pixel (QHY9)
Sensor Temp = -15°C
