By chance, I discovered the Markarian Chain in my data from May:
Markarian's Chain, 2019-05-04
Canon 50mm f/1.8 Mk I @f/3.2, Canon T3i (stock)
Orion SkyView Pro EQ mount (sidereal track + PEC playback)
75×45sec, 100×bias, 50×darks, 50×flats@ISO1600
Aligned & stacked in Lynkeos v3.1
Processed in Photoshop CS5 w/
Annie's Astro Actions v7.0 & Astronomy Tools v1.7
Scaled to 150%, cropped to 780×600

Looking forward to going after it with my 200mm f/2.8 when it comes back around…
Cheers,
BQ
