Quiero compartir esta imagen aunque quiero preguntarles sobre los colores ¿es demasiado saturación o si es irreal ?

3h of 60s exposures, with a full spectrum canon 60d, Svbony sv220, sv503 70mm with 0.8 reducer flattener, and a ioptron skyguider pro. Fully calibrated except darks no dithering. Stacked in siril processed in graxpert, pix and gimp. Any tips would be nice

Caught about 1 hour and 23 minutes of narrowband from a Bortle 4 site, and 3 hours of broadband from my Bortle 8/9 backyard, then composited the two for the best of both worlds: punchy emission line color from the dark sky narrowband, and natural calibrated star colors plus continuum context from the longer broadband stack.

Captured on a Celestron C8 with Hyperstar at f/2.1, ZWO ASI533MC Pro, EQ6-R Pro mount. Narrowband through an Optolong L-Ultimate (3nm Ha + 3nm OIII). Processed in PixInsight using the Foraxx palette via NarrowbandNormalization, then screen blended the broadband stars onto the narrowband nebula.

Just for fun, if you shrunk the Crescent down to the size of a basketball, our solar system would be smaller than a single grain of sand inside it. The math of this hobby never stops being wild

--------------------------

After a failure to capture the Sombrero Galaxy, this time I went to a relatively dark location and managed a better shot.

The idea was to blend two sets of photos (one for the foreground and a stacked one of the sky) so that the sea and Rho Ophiucci cloud complex are both visible. I messed up the foreground part so I just cropped a part of picture.

I'm still learning (this is only my 3rd attempt) so please provide constructive feedback.

1. Is this a good photo or bad one?
2. For landscape astrophotography, do you use a single shot of the foreground at higher exposure time than the photos of the sky?
3. The stars at the edges of my photo were stretched (in the uncropped original image it was much worse than what you can see here). Why? I used a tripod of course but it was a bit windy. Should I hang a weighted bag on the tripod's hook? And should the bag touch the ground, or should it hang in the air?
4. Even though I tooke 80 photos of 15s each, I could not make the photo bright enough without also making the dark parts bright. Any tips?
5. Any tutorials or books for beginners?

Thanks for your time.

This is M106, which doesn’t have another name as far as I’m aware. I’m a big fan of this picture because you can also see other galaxies to the left of it.

Certainly was not expecting this much detail out of a 250mm scope let alone my seeing conditions. 7 hours of integration, 84x300s subs. I am hooked on this target and will definitely be getting more integration.

Processed in PixInsight. Used WBPP with 2x drizzle, GraXPert to remove color cast and gradient, then cropped to native resolution. SPCC followed by BlurX correct only, StarX, GHS Stretch. Several GHS, Histogram, and Curves adjustments with various range masks. I also used HDRMT and LHE and a dash of blurx. Stretched stars with GHS and recombined with ImageBlend to produce final image.

Hi. This is my first time photographing M31, or any deep sky object and I'm incredibly happy with the results.

It was also the first test of my SWSA GTi. I was pleasantly surprised after seeing pin-point sharp stars at 380mm 60s and I think I could've gone for 500mm but I only had about an hour of dark sky so I didn't want to risk it.

I pretty much followed one tutorial from YT as I never used Siril before.

After that, I did some small tweaks in Photoshop.

IC 2574 is a dwarf irregular galaxy located about 12 million light-years away and part of the M81 galaxy group. Unlike structured spiral galaxies, its chaotic appearance is shaped by widespread star formation and enormous hydrogen emission regions scattered throughout its diffuse stellar body.

This image combines deep LRGB data with continuum-subtracted Hα integration to reveal delicate low surface brightness structure together with active star-forming regions embedded across the galaxy.

38.6 hours total integration time.

Used a 2x barlow with my bresser messier 5

messier 13. I am quite happy with the result considering it was shot with a 135mm lens.

The red stars do look a bit to red though.

Gear used:

Camera: canon r7 (unmodded) with a iso of 1250.

lens: canon ef 135mm f2 l usm, f/3,5.

mount: skywatcher star adventurer 2i.

2 hours 37 minutes of light frames of 30 seconds, 40 dark frames, 25 flat frames, 40 baies frames.

prosest with:

siril: stacking, plate solving, spectrophotometric color calibration, starnet star revoval, star recomposition stretch.

Graxpert: crop, background extraction, denoising.

Gimp: export photo as jpeg.

23 x 300s in ha, 20 x 300s in OIII, flats, bias, darks

This is a reprocess of some data I had from a couple months ago.

Stacked and processed in pixinisght with RC Astro plug ins

Equipment: WO ultracat 108mm refractor, ASI 2600 MM camera, HM17 mount, Askar 52mm guide scope, ASI 120 mini guide camera, ZWO Automatic Focuser, Optolong Ha 3nm filter, ZWO filter whee

Rho Ophiuchi region captured from Roorkee, Uttarakhand, India under roughly Bortle 5/6 skies.

This was shot completely untracked using a Sony A7III with a 70mm lens on a cheap $20 tripod. All frames were taken at f/5.6 (widest available at 70mm on this lens), ISO 2000, with 4 second exposures for a total integration time of around 3 hours.

For processing, I first stacked everything in DeepSkyStacker and imported the final TIFF into Siril using 32-bit mode since 16-bit processing was causing noticeable banding. I then used GraXpert for background extraction/gradient removal and StarNet for star separation inside Siril, followed by an initial stretch.

After that, I exported the result to Photoshop for additional stretching, levels, saturation adjustments, noise reduction, and recomposition of the starless and star layers.

This was mainly an attempt to see how far I could push an untracked setup from light polluted skies on the Rho Ophiuchi complex. Feedback and criticism are welcome.

Caldwell 4 | The Iris Nebula

164 x 300 second exposures @ 200 gain with no filter from a Bortle 4 for a total of just over 13.5 hours (so far)

Processed in Siril and Photoshop using Seti Astro Suite, Graxpert, Syqon Prism, and Veralux tools

Equipment: Sony a7rii with 28-75 kit lens and basic tripod.

Taken on January 21st, 2022 at 28mm. I took 190 13 second exposures and stacked in sequator, stretched in gimp with levels, and finally, I did normal edits in Lightroom. I unfortunately do not have the original tif file to edit again or the raw files, but would like some feedback for future reference as I plan to do some more astrophotography in the future.

I was hoping I’d get more detail in the nebulae’s and Barnards loop. Perhaps I did a poor job stretching or I didn’t take enough shots?

Found a lost card of images, ended up being a fun little timelapse of the Aurora from May 25
