This iconic duo in Ursa Major features M108, a barred spiral galaxy seen edge-on, alongside M97, the well-known Owl Nebula.
The data was captured in LRGB complemented with Ha and OIII to bring out the full richness of the planetary nebula. Its brightness particularly surprised me, as it is already clearly visible even in the LRGB data alone.
A continuum subtraction was applied to the Ha and OIII channels to better isolate the emission signal while preserving a natural look. The galaxy also reveals an interesting and different aspect in these wavelengths.
