IC 63 and NGC 281
I shot data for this image few weeks ago at 7.3.2020. little over two hours for H-alpha light and only 20 min for both O-III and S-III. Beside that I took colors from my older longer focal length images of NGC 281 and IC 63. There is a reflection nebula component in IC 63 but in this narrowband image the blueish hueas are from an ionized oxygen, O-III.
