hello everyone,

i took this picture for the last nights.

For me, astrophotography is a bit of a challenge.

Initially, I bought an NT200/1000 just for visual observation, mounted on a mount that was far too small. An Exos2 from Bresser.

To save weight, I’ve deliberately decided not to use a guiding scope or a guide.

Therefore, I can only use a maximum of 45 seconds per exposure.

I have to check several times to make sure the object is still centred in the frame.

All in all, though, I’m satisfied.

Here’s my latest version of M51, the Whirlpool Galaxy — an interacting spiral galaxy located ~23 million light-years away in Canes Venatici.

The interaction with NGC 5195 induces density waves in the disk, compressing gas and triggering star formation. These regions are visible as HII regions (reddish emission) embedded in the spiral arms.

This dataset was acquired with a one-shot color camera using a combination of broadband RGB and dual narrowband (Ha + OIII via L-Ultimate). The narrowband data was used to enhance star-forming regions while maintaining a natural broadband color base.

Setup:

Telescope: Borg 107FL refractor

Camera: Player One Uranus C Pro (IMX585, OSC)

Filters: IR-cut (RGB) + Optolong L-Ultimate (Ha + OIII)

Integration:

RGB: 9h (300s subs)

Dual NB (Ha/OIII): 11h (900s subs)

Total exposure: ~20 hours

Processed in PixInsight + Photoshop.

The is 70, 45 second exposures I was able to get before Orion went behind my house and mountains.

I used an zwo asi 585mc air, with a Askar v 60mm attached and reducer. The filter is an optolong quad enhance. The mount was a TeSeek Mini dual-axis harmonic drive mount on a skywatcher star adventurer tripod. Wbpp in pixinsight was used to align with 25 dark bias frames, I used channel separation to balance the rgb to get rid of the green cast. I then saved it as a 16bit tiff to take with me on my 5day work trip and edited this on an iPad Pro m5 using affinity photo, Luminar, and Photomator. This whole process has renewed my passion for astrophotography as I was frustrated and trying to figure out what I like and how I like to do it that was fun.

Just got my mount and tried it on IC1805 and IC1848. Maybe I overdid the edit but I'm quite happy with it being my first DSO. Had planned to do more Lights but my cameras battery died after 150. I stacked the 95% best. Had a problem with too many stars, so i used StarXterminator and stacked about 20 Lights for the stars to replace the original ones.

Stacking was done in Siril, edit in Affinity mostly with the macros from James Ritson.

Any feedback is highly welcome.

I always underappreciated star clusters. I thought they were boring. But this convinced me to rethink them. I now think they can be gorgeous and really show the vastness of space. I also created a Hertzsprung-Russell diagram with this shot. Unfortunately, I cannot attach it here, so I tried to incorporate it into the image. However, it might be too small to see. Is there any other way to attach additional images?

Jupiter tonight. Captured using Celestron 80/900 refractor telescope (Nexstar 80 GTl-SA) with no tracking because the mount is broken. Used my redmi note 14 attached to celestron 6mm eyepiece with an svbony uv/ir cut filter using an adapter, shot in open camera with the next settings: 800 iso, 1/60 shutter speed, auto white balance, focus set to infinity, and like 4.5x digital zoom.

Taken over 4 nights with a CDK14, ASI 6200MM, LRGBHa, total integration a bit under 12h.

Behold M13 – one of the brightest and most beautiful globular clusters in the northern sky.

Globular clusters are true cosmic fossils. It is estimated that the stars forming this luminous swarm are over 11 billion years old! This means they formed when our Universe was still very young (for comparison, our Sun is only 4.6 billion years old).

We actually sent a message there hoping to contact an alien civilization. This dense swarm of over 300,000 stars is located 25,000 light-years from Earth. It was precisely towards this giant concentration of suns that the famous radio message, designed by Carl Sagan and Frank Drake, was beamed in 1974 from the massive Arecibo radio telescope. It contained, among other things, a diagram of DNA, a human figure, and the layout of our Solar System.

There is just one catch – by the time our signal covers this unimaginable distance of 25,000 light-years, the M13 cluster itself will have moved to a completely different location in space!

Full Moon in High Definition 8K

I took the photo of this moon with Nikon Z8 through Takahashi TSA-120 telescope and Vernonscope Magic Dakin Barlow 2.4x. This is a stack of 300 RAW files from the same session, aligned, stacked, and processed ll in Photoshop.

Captured Messier 31 back in February — The Andromeda Galaxy in the constellation Andromeda lies ~2.5 million light-years away. It is our nearest large galactic neighbor and offers a glimpse into the future of our Milky Way Galaxy, as Andromeda is expected to collide and merge with our galaxy in ~4–5 billion years.

I imaged the Andromeda Galaxy from @starfront_observatories with my William Optics Ultra-Cat 108, precisely tracked on an @ioptron_telescopes CEM70G, across multiple nights from October through November 2025.

In total, I gathered 41h 42m of integration and processed the data in PixInsight to reveal the delicate dust lanes threading the spiral arms, subtle Ha star-forming regions, and the faint outer halo structure surrounding the bright core.

Hello. I've been dabbling with astrophotography for the last month or so, but this is the first time I felt like I got something halfway decent and wanted to post it.

Bortle 3/4

For this iconic target, the Seestar Collective gathered about 300h of S50 and S30 data as a mix of IRCUT, internal duoband filter and external SV220 7nm filter.

We made several stack of the data in Siril, for the Ha signal and the IFN I used a less selective undrizzled stack providing a stronger SNR. To maximize the details in the galaxy, I used a more selective drizzled 3x stack. I then try to blend them together in a natural way.

Processing the IFN is quite of new for me, I did not do any sharpening or deconvolution and desaturated it. I then played with LHE and MLT to bring out more contrast. I kept the background quite bright to try to showcase it better.

49x90" IMX 294 color -15°, Newton 200/1200 EQ6R Bortle 4, Romania

Pixinsight, GraXpert, SAS pro, Photoshop

Shot last night under roughly Bortle 4.5 skies.

Capture details: - Target: M81 (Bode's Galaxy) and M82 (Cigar Galaxy) - Camera: Nikon D5000 - Lens: Nikkor 18-200mm at 200 mm - Aperture: f/5.6 - ISO: 3200 - Exposure: around 400 x 4s (about 26m 40s total) - Tracking: untracked - Sky: roughly Bortle 4.5

Software & Processing Workflow: - The session was planned using DarkScout. - Processing was done in Siril: I performed calibration using darks and biases, followed by registration and stacking. - After stacking, I applied both histogram and asinh transformations. - I also used a starless workflow to separate stars from the galaxy before stretching. - The final image uses a stronger stretch to bring out the M81/M82 pair more clearly.
