This was the first try with the L-eNhance filter on the ASI533 and Samyang 135, wide open at F2. I wanted to test the signal at F2 and F2.8 but this was a bit of a fire and forget mosaic that I set off on Saturday evening so I didn't get a chance.

The L-eNhance has quite a wide band pass, but I'm not sure if I was still being impacted by loss of signal due to shifting at this speed. Hoping to get a quick test soon.

This is a 2 panel mosaic with a wide overlap. Around 1h 45min per panel (180s subs).

Captured with Voyager, calibrated and stacked with APP then processed in PixInsight.
