Hello
I recently received the L-Synergy filter from Optolong Astronomy Filter to test.
It is a 7 nm Duo-Band (SII-OIII) filter tested under moonlight conditions at over 80%.
I paired it with the L Ultimate (Ha-OIII) filter to obtain an SHO image.

 

 

The image was taken with my Askar 140 Apo (F7) telescope and an Asi2600 MC Air colour camera.
Once the images were stacked, I extracted the red layer from the L Synergy to obtain the SII layer, the red layer from the L-Ultimate for the Ha layer, and I performed a 50% pixelmath on each green layer of the two filters to obtain the OIII layer.
The stars were created from the stars in the L Ultimate filter using the Seti Astro NB to RGB stars script.
L-Synergy filter: 115x300s (9h35)
L-Ultimate filter: 221x300s (18h25)
First test very conclusive even in intense moonlight conditions. I'll let you judge for yourself with the full version:
