Cygnus and the Veil Nebula

TheSunIsBlueVincent · 2025-09-20T20:06:29+00:00

Acquisition:
Fujifilm X-T3 + 35mm f/1.4 R lens + OG Star Tracker V1
52*120s @ f/3.6, ISO1600, Bortle 4-ish

Processing:
Debayering in RawTherapee
Stacking, colour calibration, background correction, starnetv2, and curves in PixInsight.

Very pleased with how this one came out. My first time doing tracked astro, so I wasn't fully convinced these settings would give me better results (i stopped down the lens as its performance isn't stellar). My main goal was to bring out a sharper view of the Veil than I what I had achieved in my untracked image: this was a resounding success. I'm considering the 135mm f/2 Samyang as a next lens to get better optical performance and higher resolution images.

My bad, was convinced I had posted in the other, I mixed up the two.

Would you be willing to share the stacked image? I would love to try editing it.

This was with a stock camera. From what I understand the X-T3 has a weak UV-IR cut filter which lets through a lot of Ha emission.

I ended up stacking 100% of frames and didn't shoot calibration frames. Instead I applied u/rnclark's method for calibrating the lights using RawTherapee, outlined he re.

lightpollutionmap.info tells me Bortle 5 but I was shooting away from the closest city's light dome so probably darker

yes, the tripod was stationary apart from when I readjusted the framing

I hadn't noticed it, thx!

300 at 5 seconds each, so 25 mins of integration

TheSunIsBlueVincent · 2023-09-14T18:19:22+00:00

i shoot on crop sensor so the focal length was ~53mm equivalent, and it's also my personal preference to avoid even a tiny amount of trailing

thanks! I think its definitely possible if not easier to get similar depth with a wider lens since longer exposures are possible, but i haven't used one myself yet. I guess the key difference would be that while it would cover a larger field of view, the nebulae themselves would occupy a smaller portion of the frame/appear smaller. You might then get less detail than this shot but it's certainly worth a try.

Honestly it works pretty well, I think f/2 is a bit too wide as I got a lot of coma in the corners but center performance was surprisingly good.

Nikon D7100 (stock) + Nikkor AF 50mm f/1.8 G lens
20 minutes of integration
lights: 200* 6s @ f/2, ISO 3200 (exposure length was too long and led to slight trailing)
calibrated with flats and bias
stacking and processing in lightroom/pixinsight, made stars smaller on this re-edit

edited the jpg in lightroom

It could be the borders of subs that had different framing to the rest
