M42//The Great Orion Nebula.

Photo taken and processed by myself. January 17th, 2025.

orion trapezium core by u/brownieboy2222 via r/astrophotography

photographer’s notes:  

Stacked and processed in pixinsight with RC Astro plug ins. Used HDR composition to not blow out the core

Scope:Askar 103APO, Camera: ASI533MC pro, mount: HEQ5, Askar 52mm guide scope + asi 120 guide camera. Optolong Lenhance dual narrowband filter

This was a lengthy processing workflow for me. First time trying HDR comp and I think it came out pretty well

Old Glass, Soft Morning

The flower still carried the rain. The air smelled of leaves and silence. And somewhere between old glass and morning light, a tiny life paused long enough to become a memory.

Captured with a vintage Pentacon 100mm f/2.8 on a Canon R7 — proof that some lenses do not merely record the world, they soften it into feeling.

Not everything beautiful needs to be perfect to be remembered.

The Orion nebula (aka M42)

This is a very bright emission/reflection nebula in the Orion Nebula (situated just below the belt). In low light pollution areas, it can be visible with the naked eye (better with binoculars). The nebula's apparent size is about 1°, around twice the size of the full moon. Due to its size and brightness, it's one of the most photographed deep sky objects.

It was the first test of my new remote telescope rig, not completely satisfied with the result, especially the outer parts and core of the nebula. Weather was not the best (some high altitude clouds) and the system is not completely calibrated/installed (still waiting on some equipment). This led to the 300s sub exposure to be ok and the 30s, originally intended to help with the core, to be only usable for the stars.

(my image is taken using a CarbonStar 150/600 newtonian telescope with a 0.95 coma corrector, ZWO ASI294 monochrome camera and Baader 6.5nm Ha and OIII filter. 12x300s for the Ha filter, 12x300s for the OIII filter, plus some 30s images in both OIII and Ha for better stars, total imaging time of about 2h, stacking and processing done in PixInsight.)

Orion Nebula, n.d.

[whirligig-girl]

Eaurp and Slamtha do some amateur astronomy outside of Flugoz County during their first year of gooniversity (goo university). Eaurp is observing the Ulyp Nebula, known to humans as Messier 42.

Eaurp's telescope is a 140.8mm aperture f/8 Cassegrain-like design, with a sub-aperture correcting lens on the secondary mirror and before the eyepiece. It's resting on a home-made equatorial pipe mount.

The view on the upper right is roughly what Guz sees through the eyepiece. A human would see slightly differently.

Names (given by humans) of the bright stars visible in the image. The view is accurate to the Zwo-Nmu system, but I have only a vague idea of where the celestial north and south poles are on Gymnome. Zwo-Nmu is 64 lightyears away from the Sun, so the constellations are noticeably different and overlap in strange ways, but many of the same stars are visible.

The glowing of Eaurp and Slamtha's slime has been exaggerated because it looks cool. In reality their bioluminescence would only be visible under much darker skies, and it'd look like a colorless ghostly grey due to the human rod cell's insensitivity to dim light.

This glow is a limiting factor for Gymnomi visual astronomers when observing at the extreme limits of their visual sensitivity, even when consciously suppressed. Dark-slimed astronomers glow less and so have a slight advantage over bright-slimed astronomers. There are also drugs which suppress the bioluminescence, but they can have side effects, so they're only used by the most dedicated visual astronomers.
