Objects in field: Crab nebula, M 1, NGC 1952

Equipment: ZWO ASI1600MM COOL

It was a challenge to combine all channels into a single decent looking colour image. For this I used RGB, iR pass, Ha and OIII. Through the 8" dob's tube worn by the EQ6-R I shot about 8h on each narrowband and about 2h on each RGB and iR.
