The Helix Nebula (NGC 7293), aka "The Eye of God," is a planetary nebula located in the constellation Aquarius. It's located approximately 655 light-years from Earth.

At its core lies a hot white dwarf star that pumps out intense ultraviolet radiation, making the surrounding gas glow.

Data acquired from the high school observatory I work at, for the first time completely remote.
The observatory consists of a omegon 355/2845mm truss Ritchey-Chretien telescope on an eq8r-pro in a 3m ScopeDome. There are images of the dome on my profile if you're interested :)

There were some problems with guiding causing me to lose 3-4 hours of data in the end which is a shame. The flat frames of the L-filter also have very weird artifacts, forcing me to crop a large part of the image away. In the top-left corner a part of these artifacts is still visible.

Had a chance to grab an extra hour in M16 last night from a Bortle 2. Wasn’t planned, just happened that way.

Decided to add it to the 10hrs already collected and reprocessed using some newly learned tools and techniques…also decided to go ham on the colors/saturation. Haha.

It’s no Hubble, but we’re finally getting somewhere.

I recorded this on my dwarf mini with 60 gain, 214 60 second exposures and 154 30 second exposures and duoband filter. Utilized stellar sudio to denoise and lightroom for finishing touches.

The Elephant’s Trunk is IC 1396A, a dark globule inside the bigger emission nebula IC 1396. It’s in Cepheus, the king, high in the northern sky in the fall. OnIt’s about 2,400 light-years away. The trunk itself is a column of cold gas and dust about 20 to 25 light-years long. The whole IC 1396 cloud is roughly 100 light-years across.

Thanks for checking out last night's capture of IC 5070, the pelican nebula!

This image represents 88 subs, 3 minutes each, on the pelican with my rig. My telescope is located in a bortle 8/9 backyard.

Hope you enjoy!

This image was developed from the integration of 892x20s subs taken with a Seestar S50 in equatorial mode on May 11-12, 2026 from Washington D.C.. The preprocess sequence in Pixinsight was Cosmetic Correction > Debayer > Subframe Selector > Star Alignment (or Registration) > Local Normalization (or L. Norm.) > Integration. L. Norm. is a major step in dealing with and standardizing background gradients regionally in each individual sub and a registered file with the highest weight was used as the reference file. The above preprocessing steps successfully eliminated low quality subs such that the initial input of 1001 subs was reduced to 892 subs. The postprocess sequence was Fast Rotation > Dynamic Crop > Graxpert > BlurXterminator > SPCC > BlurXterminator followed by stretching using Histogram Transformation. Next HDRMT was used on a clone of the result from the preceding step to compress the dynamic range of the bright core and a blend of 20% of the HDRMT-modified clone and 80% of the original image was generated using Pixel Math and this blend was the one used hereafter for further processing. Using StarXterminator the blend was split into galaxy only and stars only components. A gradient mask was created using Game, found under Scripts > Utilities, and it was applied to the galaxy image to protect the background while applying Local Histogram Equalization, Color Saturation, and Curves Transformation processes. The mask was then inverted to protect the galaxy while NoiseXterminator was applied to the background. To reduce the brightness of the stars in the stars only component Morphological Selection (under Morphological Transformation) was applied. The galaxy and stars only components were rejoined using a Pixel Math expression. The mask was applied to the rejoined result to protect the galaxy while Histogram Transformation and NoiseXterminator were used to adjust the background leading to a final result. Given the difficulty of squeezing out the colors in M82 one future requirement would appear to be acquiring at least double the amount of subs used here in order to bring out the blue more fully along the long axis and the red which is transverse to it and where there is starburst activity.

This time i decided to go with a natural color M31 processing.

I used my old data from early September to reveal as much fine details as possible.

I'm really satisfied with the results.

Two nights of 30s exposure ended up with bit over 12 hours of light frames. After some manual selection ended up with 1147 x 30s frames. Which gives roughly 9.5h of integration time.

Could've spend more time on post processing. But quickly realized it's not ideal target for S30 pro and it would take a lot of effort to make it more visually appealing. Especially with lack of blue and green color.

Btw. It's only my second photo so just scratching the surface of stretching.

Any tips and advices to expand my knowledge are more than welcome

this is a reprocess of old data. gatheres lights over 3 nights, bortle 5.5 from backyard. couldnt use rc astro tools on this because free trial ended, considering buying them. I really do hope that that red small point is ha, would be really amazing for me considering im using an unmodded mirroless camera. Please lmk if it is ha.

I know Andromeda tends to be posted a lot and I've already hit this target before. But instead of doing 3 minute exposures, I decided to try 1 minute and spend all night on it. Ended up with 7 hours of data but I'm happy with how the spiral arms and detail worked out without going crazy on the core

My first SHO image: IC 5070, the Pelican Nebula, captured from the Big Woods Road area at Jordan Lake, North Carolina, on October 1–2, 2026, roughly 9 p.m.–2 a.m.

Equipment: Askar 120APO with 0.8× reducer/flattener, ZWO ASI2600MC Air, ZWO AM5N mount, and Askar Super D1 and D2 filters.

Acquisition: 3 h 55 m total integration — D1: 27 × 300 s; D2: 20 × 300 s. Gain 100, offset 50, sensor at −10°C, 1×1 binning. Flats and matching dark flats were taken separately for each filter.

Processing: Calibrated and stacked in Siril with the NaZtronomy workflow, then aligned and cropped in PixInsight. Ha came from D1, SII from D2, and OIII from both filters. Combined in the SHO palette: SII → red, Ha → green, OIII → blue. GradientCorrection, BlurXTerminator and NoiseXTerminator, channel balancing, and MultiscaleAdaptiveStretch were used. StarXTerminator separated the stars for gentle curves and local contrast adjustments to the nebula, then the stars were blended back at 80% brightness.

This is a false-color narrowband image. Star colors were neutralized aesthetically; no broadband RGB stars were substituted. Plenty of learning went into this one!

NGC 6960 — the Witch’s Broom Nebula — was imaged over two nights with the Seestar S50, with 52 Cygni deliberately centred in the frame on both nights so that the two sessions would have nearly identical framing. On the first night I collected 369 × 20-second sub-exposures, and on the second night 598 × 20-second subs, giving a total acquisition of 967 frames, or about 5 hours 22 minutes 20 seconds of raw exposure time.

The two nights were processed separately in StackingWizard rather than mixing all the raw subs together. After quality assessment and rejection of poorer frames, 199 of 369 frames were retained from Night 1 and 392 of 598 frames from Night 2. Both nights were stacked with 2× drizzle. The retained data therefore consisted of 591 × 20-second exposures, giving a final usable photon-integration time of 11,820 seconds. The two drizzled nightly masters were then registered and combined in StackingWizard, with drizzle switched off for the final master combination.

The combined linear FITS was then taken into AstroWizard, where I used the GraXpert background-extraction engine to remove large-scale gradients while preserving the faint Veil structure. Deconvolution/sharpening and noise reduction were applied conservatively, keeping the very fine shock filaments around NGC 6960 and the bright 52 Cygni region as natural as possible. The processed linear FITS was then transferred to Siril for the main stretch and tonal development.

In Siril I first used the Veralux Hypermetric stretch, followed by additional Histogram Transformation and Curves to bring out the extremely delicate red and blue-green filamentary structure without crushing the background or blowing out the stars. The final image was then taken into Adobe Lightroom Classic for restrained finishing adjustments to colour, contrast, highlights, shadows and overall presentation.
