Interacting galaxies Arp 84, 104 en 141 (and I'm back in town)

Hello all
I'm back in town (again). After the months with the complicated gallbladder infection, some other things highly needed my attention.
But it's all sorted out and my health is also almost back on track.
Didn't do much with imaging, but here 2 objects I captured and one reworked.
Arp 84 (NGC 5394 + 95, Heron galaxy) is a reworked version from RGB and Ha data from a few years ago.
Arp 104 (NGC 5216 + 18, Keenan's system) and Arp 141 (UGC 3730) I captured in the last couple of months.
Stacked with SiriL (m.b.v. SiriLic), basic processing in SiriL, all other processing in Photoshop.
For each set 20 x darks + 50 x (dark)flats.
Meade LX200 8" f/10 ACF + Zwo ASI071MC Pro on an Ioptron CEM25EC mount without guiding.
Capture software: SharpCap Pro 4.1
