This data was meh, needed some heavy attention. But with better attention to color and general balances in stretching and HDR I'm happy with this rework.

MGC database doesn't have this region yet so I used a manual reference, thanks to @elfin burrow for lending the data.

Esprit 80
ASI1600MM
Meade LXD75 OnStep'ed
ZWO LRGB/Ha 1.25" mounted filters

Bortle 5/6

The saturation on the stars also participates in the vibe, looks natural

Man, every single time I think about getting my first rig with an OSC camera, you mono guys show up and send me back to the drawing board... great result 🔥

Thanks! Yep, mono is the way to go.

In this instance I switched to software and played with starspikes 4, and found out it can create some natural looking diffraction.

No drizzle, I find it unnecessary in my case.

Your sampling is 1.96"/px which is quite good yes

The very slight increase in potential sharpness is not enough to justify the processing times and increased storage drain.

you also get some extra details from mono composition itself

Yea mono squeezes a bit more out any said optical system.

Compared to osc

#

The lack of a Bayer matrix helps in many areas.

Basically yes, instead of each pixel being restricted to R G or B, with a Luminance filter, you can collect the whole visible spectrum. But resolution and overall signal gathered is increased with a monochrome sensor as the WHOLE sensor is dedicated to R G or B. Whereas a Bayer matrix divides the sensor up between RGB.
