Description

Equipment: Vixen M80 + Altair DERF + Baader TZ4S + 2x Lunt40 etalons.
Capture: PlayerOne Apollo M-MAX (IMX 432), Gain=200 Exposure=3.0ms
Processing: AS4 (5% of 500, or 25), IMPPG curves + sharpen.

I thought the bright/blurred image artifact around the top/right might be due to the UV/IR filter being in very close proximity to the EO 0.5nm trim filter.
Perhaps reflections or something. Here I've replaced the UVIR with a 0.1mm shim (OD 28mm ID 20mm) and the problem is still there.
The issue has since been identified as a 2" scope adapter which "slops" by the thickness of a fingernail with this heavy image train behind it.

Anyhow - for a "3rd light" of this setup I'm quite pleased it's showing some potential.
Neither of the Lunt40s were tuned here. They seem close to "on band" behind the TZ4S.

Newton rings removed with a Daystar Interference Eliminator. Very pleased with this gadget!
