Sony A7iii + 24mm f1.4, ISO 2500, f1.8, 13s

First light with new telescope

First time trying out PixInsight, followed a video made by Cuiv, The Lazy Geek. I think it turned out good, although i am struggling with the purple gradient on the corners, if anyone has any suggestions on how to help me with that, please let me know!

Integration: 120s x 45 subs, with flats, darks and biases. Taken with no filter.

PixInsight: Background extraction -> Spectrophotometric colorcalibration -> Graxpert denoise -> statistical stretch -> starnet star removal -> curve transformation.

4.5 hours of integration time in bortle 2/3.

Stacked in siril. background extraction, color calibration, blurx, gradx, noisex and starx, stretching in PI. Luminance masking and final touches in photoshop.

This morning i captured Europa making a shadow on jupiter with the red spot and io also visible, i'm quite happy with the result ! Equipment : dobson 200/1200 on equatorial platform, camera Neptune c-II Softwares : pipp, autostakkert, astrosurface

Equipment: Telescope - Askar 71f Camera - Minicam8 Filter - FCE (built in filter) Mount - Eqm35

This is definitely the best photo I've ever taken. I think using the FCE helped a lot as I captured a lot more Hydrogen than past shots.about 1.5 hours of data from bortle 7.5 (no light pollution filters needed!!!) and then stacked in dss, and processed in siril using mainly different stretches like generalized hyperbolic, and curves. Also, used graxpert in siril to get rid of gradients and then plate solved and photometric color calibrated.

This night I got my very first 5 minute exposure and it was actually pretty good. However, this was compromised of mainly 90s shots.

This is my first 3-hour trial since switching to a DSO camera. I need to work more on both the shooting quality and especially the post-processing. I'd be grateful for any suggestions.

I couldn't get the background smooth enough; I think the galaxy saturation was too much. I'm experimenting with bringing out the details, but I haven't gotten anything sharper yet.

200 lights @ 60 seconds (3 hrs 20 minutes)

50 darks @ 60 seconds (I did not use darks while stacking)

50 bias

20 flats with NINA flats wizard

Processing: Graxpert (Stack, BG Extract, Noise Reduction), Siril (Stretch a little and Star Removal), GIMP (Saturation, Curve, Hue-Saturation, Sharpen and Star recomposition)

When stacking, I tried wDBF, woDBF, wo Dark etc and the one wo dark appeared better than others to me. Thats why I did not use darks.

I took this photo in Shenandoah National Park on October 10th, 2024. This was during the massive substorm at around 10PM that night and I'm still in awe of how these photos turned out.

Used siril to: Stack Align Split to starless and starmask Stretch

And graxpert to: Extract Background Denoise

Soo, i removed the Sensor from my Canon and removed the UV and ir Filters and then went ahead and took a piece of Aluminium and carefully scraped Off the Bayermatrix. I was super careful with the Sensor so there was still some Matrix left in the Corners and edges. This results obviously in artifacts so i Had to crop it hard.

All in all i am quite happy i got a Mono Cam for No Money at all.

Ive read somewhere people would Use metalpolish to get rid of the Last remnants of Matrix, can anyone Here confirm such a Thing? Or has any Tips on better cleaning the Sensor?

SH2-155 - The Cave Nebula in SHO w RGB Stars

The Cave Nebula (Caldwell 9, Sh2-155) is a diffuse emission nebula within a larger nebula complex that includes a reflection nebula, and dark nebula. This deep-sky object is located in the constellation Cepheus and lies roughly 2,400 light-years from Earth.

This was imaged over the past few weeks from my rig at Starfront. I believe this is the first time I shot it.

I haven't done a SHO color palette in a while. I felt this palette really brought out the OIII blue vs the others that were primarily red.

First time successfully imaging! Cygnus cluster via old Nikon D3100, Benro Polaris, and clumsy stacking/editing session. Roughly 80 10 second subs in Philly suburbs.

I've been lurking and studying a long time before finally making something close to a real image, love this sub as it is full of great information and inspiration.

What's up everybody. M31 was finally high enough in the sky and the low clouds broke free so I took an hours worth of data and slapped this together quick. Gear is a ZWO 2600 MC Pro camera, Red Cat 71 scope, running on an HEQ5 Pro mount. Imagine integration was a result of 32 x 120 sec exposures, 100 gain, and some luck! stacked in the asiair stacking tool, with color editing from my cell phone. How we looking?

Really happy with how this turned out in a locally bright bortle 7

55x 300s in h-alpha, 57x 300s in OIII, 60x 10s each R,G,B channel for stars. 9 hours 50 mins total integration.

This is the deepest I’ve gone on a target in a while. Really need to start getting into the 20hr range but I’m just so impatient lol.

10hrs of integration! This image was built using narrowband separation with the Optolong L-eNhance filter. By extracting the individual channels, I could isolate the two strongest emission lines: 🔴 Hydrogen-alpha (Ha) 🔵 Oxygen-III (OIII)

Workflow: ➡️ ChannelExtraction – separated Ha & OIII ➡️ PixelMath – blended with: R = 0.6Ha + 0.4OIII ➡️ LRGBCombination – recombined into the final HOO image

This mapping highlights the fiery hydrogen regions in red/orange against the delicate oxygen filaments in blue, giving that classic bicolor nebula look.

Taken on August 22, 2025 in Bortle class 4 skies. This image of Andromeda is a combination of 24 x 2-minute exposures for a combined exposure of 48 minutes. Additionally, 10 dark and 10 bias calibration frames were collected. Equipment and settings are listed below.

Camera: Canon EOS T7 Lens: Sigma 150-600mm f/5-6.3 Contemporary Mount: Sky-Watcher Star Adventurer 2i Focal Length: 300mm Exposure: 30 x 121” subs with 24 being suitable for stacking. ISO: 1600 Aperture: f/5.6

Post processing: the light and calibration frames were stacked in DSS and the 16 bit file brought into Photoshop. In photoshop, a series of curves and levels adjustments were made to bring out details of the galaxy before a dark threshold layer made for setting black and white points. Colour correction of the galaxy was performed with colour range selections and colour balance adjustments. High pass filter applied to bring out details of the galaxy’s dust lanes. Several more curves and levels adjustments were carried out. Minor adjustments to the exposure, clarity, dehaze, and highlights settings were carried out with the camera raw filter before exporting the image as a PNG file and opening it in Lightroom. Adjustments in Lightroom included a radial gradient filter to adjust exposure, highlights, and WB of the galaxy and cropping of the image. Lastly, the image was brought into denoise AI where a custom sharpen/denoise setting was applied.
