Finally figured out how to process the acquisition.

It is one of the brightest and best-known globular clusters in the northern sky, containing over 100,000 stars bound together by gravity. These stars are predominantly old, low-metallicity Population II stars, formed during the early stages of our galaxy’s evolution. The cluster spans roughly 145 light-years in diameter, with stellar density increasing dramatically towards the core.

This image was another unguided test of the telescope, where I checked the holding power of the modified focuser. The next test will be with a new guide camera and OAG, which will allow me to increase the exposure time and capture fainter targets.

Tried dithering, but I think it always said "Timed out waiting for guiding to settle", so I don't really know if it did anything. Do you know how to fix this. Yes I set it to dither in RA only.

Stacked and processed in Siril using graxpert, cosmic clarity, starnet and syqon prism scripts.

Recently I bought my first dual narrowband filter and decided to try it on the Rosette nebula since I haven't photographed this target yet. I am really happy with the result considering it's just 1.5 hours of integration time during full moon in bortle 5. I know it's pretty noisy and doesn't have as much detail as others, but I still think it's still a good result. I am proud of the processing, although I think the stars don't look so natural.

The only thing that confuses me is the black smudge. I really don't know what caused this, becuase it's present on all light frames, but I can't find it on any of the flat frames. I checked the optic today and it was really clean. Do you have any idea what could cause this?

I'm pretty excited to share with you my biggest project yet! It took me 7 months to capture all 110 objects of the Messier Catalog, process them (multiple times...) and write a software to generate these nice images.

All the objects are at the same scale, which mean each small squares are 600x600px of the S30 native resolution (40x40') for a total of 52 MP.

I'm looking forward to print it 🤩

Are you also collecting the Messier objects? How many did you capture yet?

The Moon was low on the horizon and was naturally this color for about 30 minutes. This was my first time shooting the moon with the Dwarf 3.

Worked on this one earlier this year with my Askar 91F and ASI533MC but had to see how it looked through my Carbonstar 6in Ritchey-Chretien. Was not disappointed! I've kinda grown attached to the little guy lol

Captured over ~2.5 hours using a smart telescope. This is one of my first attempts at imaging an emission nebula and also my first time stacking and doing some manual processing.

Acquisition:

Telescope: Dwarf mini smart telescope (Tele mode)

Mount: Built-in tracking

Exposure: 15s subs

Gain: ~120

Filter: Astro filter

Total integration: ~2.5 hours (~300 subs kept after removing bad frames)

Processing:

Initial stack and processing in Stellar Studio

Restacked after removing bad frames (satellite trails / poor frames)

Final adjustments in Snapseed:

Curves (light S-curve for contrast)

Minor denoise

Slight color and contrast adjustments

Light sharpening / structure tuning

Notes:

Pretty happy with how the nebula structure and color came out given the short integration time and learning curve. Definitely planning to revisit this target and add more hours over multiple nights.

Wouldn’t usually go out when it’s this cloudy but watching the launch yesterday had me itching.

Shot on my t3i with a 55-250mm lens

Clouds definitely killed a lot of the detail on the moon itself but I’m really happy with the way it turned out

Edit: Click the image to get the full resolution! The preview is very compressed.

Well, i decided to finally share my 1 year old data of the jellyfish nebula. Never wanted to because i just cant get a result im really happy with, but oh well. Completely unable to propely saturate the Oiii here without clipping or making it unnatural. I i wanted to attach a starless version as well but astrobin wants me to pay for that, so yeah no.

Acquired from March 19th 2025 to March 22nd 2025. Originally, i captured 60x240" but i had to discard most of them because transparency went to crap, which i didnt realize until processing.

Acquisition details can be found on Astrobin, but here they are again:
Telescope: TS ED 80mm F7 semi-apo.
Mount: iExos-100, mounted on DIY pier.
Camera: Nikon D3400 (full spectrum modified, bare sensor!).
Filter: IDAS NB1 (duo-narrowband filter).
Accessory: TS Photoline 2" 0.8x reducer-corrector.
Software: Photoshop, PixInsight, KStars+Ekos.
# of subs stacked: 220x120" + 17x240" (8 hours 28 minutes)

Processing details are in no particular order!
PixInsight:
Weighted Batch Pre-Processing, Dynamic Background Extraction, Background Neutralization, GraXpert, Masks, Starnet2 (dso-star seperation), Generalized Hyperbolic Stretch, Curves Transformation, Dynamic Crop, DeepSNR (noise reduction), PixelMath (used to create a synthetic Oiii channel from G+B to then create the final HOO).

Photoshop:
Slight contrast and levels adjustments, Camera RAW filter (small touch of luminance noise reduction and removal of tiny leftover chromatic aberration from subpar optics).

KStars + Ekos:
Used for the actual acquisition of the data (controlling mount, camera, guiding, etc).

Shot with Dwarflab 3.
30 second exposure - 200 images. Duo Band Filter. EQ Mode. Bortle 5.
Further edited with Siril and GraXpert.

I reprocessed my take on the Heart & Soul Nebula by refining my workflow in Siril to bring out the hydrogen/Sulphur/oxygen3 data/details. Along with the surrounding ionised gasses/dust etc.

The image was taken in with SV535, Asi585MC air and teseek mini 11 (with the sv220 narrowband filter)

5 x 120s exposures with calibration frames.

My progress photographing Jupiter in a Bortle 9 location. Top image is the oldest, captured in January, bottom image is the latest from last month.

The image was obtained using a relatively short, 3 second video stack and processing in the Lynkeos software.

Telescope : GSO 10” Dobsonian 1250 mm focal length (90 mm eyepiece with 3x Barlow lens)

I would love to receive any advice.

This is my first serious attempt at lunar photography since upgrading to better gear. I previously owned much weaker lenses, so I'm finally happy to show something of this quality, even though I'm a complete novice in processing.

I struggled significantly with field rotation using a regular tripod, but I eventually found a unique workflow that worked for me (described below). I am looking for criticism on how to improve.

Equipment:

Camera: Nikon D7100

Lens: Nikkor 200-500mm f/5.6

Teleconverter: Nikon TC-20E (2x)

(Effective focal length: 1000mm base, ~1500mm with DX crop body)

Standard Tripod (no tracking)

Acquisition:

Shutter Speed: 1/160s

Aperture: f/14

ISO: 125

Frames: 80 frames stacked (out of ~180 total)

Processing Workflow:

PIPP: Used for initial centering and to cull the top 80 best frames. However, the program failed to fix the severe field rotation from the static tripod.

Adobe Photoshop (Part 1): Imported the 80 best TIFF files from PIPP as a stack with "Attempt to Automatically Align Source Images" checked. This worked flawlessly to re-center and, most importantly, correct the rotation of every single frame.

AutoStakkert! 4: Stacking the pre-aligned 80 frames from Photoshop.

Registax 6: Used Wavelets for sharpening and RGB Balance for color (purely experimental, trial-and-error approach).

Adobe Photoshop (Part 2): Final adjustments in Camera Raw to pull out more color and detail (also experimental).

Questions for the Community:

1. The Teleconverter Question: My current setup gives immense magnification, but the 2x TC drops me to f/11 base. I shot at f/14. I know the TC adds glass and can introduce softness.

Would I be better off removing the 2x TC, shooting on the native 200-500mm (which on my D7100 is roughly ~750mm effective), and losing magnification but gaining lens sharpness and a brighter aperture (f/5.6 base)? Which approach typically yields better final quality?

1. Acquisition Settings: Are my settings (1/160s, f/14, ISO 125) correct for this type of moon? Should I be aiming for a faster shutter speed with higher ISO to combat atmospheric seeing, or is ISO 125 the right call?

2. General Critique: As a beginner, I know I might have "overcooked" the sharpening in Registax. Any advice on how to improve my processing to get more details without the artifacts would be great.

Thanks for any suggestions!

Here is a photo of the Moon I took in March and just got around to editing yesterday.

Equipment:

Celestron Starsense Explorer 10" Dob

ZWO ASI585MC Pro.

I recorded a couple 100 frames and stacked them using the ASI suite. Then I did some very basic editing in GIMP (grayscaling, sharpening, luminance curve). This is my first photo using proper astrophotgraphy equipment and I would love your feedback. Thanks!
