Description

From my usual Bortle 7 location, galaxy season using the Mewlon 180c and IMX432 is going pretty well, barring the ever present cloudy skies. Turns out that using filter offsets for a mono setup, even with advertised parfocal filters, is a good idea and the results are much sharper than what I got with my shot of M106 previously.
Managing the huge brightness differential between the core of the galaxies and the outer arms is not particularly easy to do, but careful stretching and luminance masks does a good job of revealing the intricate shapes of galactic material swirling around the two interacting galaxies.
