Barred spiral galaxy in the constellation Ursa Major. Only 40 minutes away from the 2nd magnitude star Phad in the big dipper.

Small Object at 7 x 4 minutes but has Well defined spiral arms and core shape.

At magnitude 9.8 I thought my telescope might struggle. Seems this magnitude is concentrated in the spiral arms and core so this image worked out nicely.

50% moon in taurus tonignt. Didn’t cause any problems with this image.

LRGB image with 5 hours and 35 minutes of data. 34 x Lum 11 x Red 11 x Green 11 x Blue 5 minute exposures.
