About 3.5 hours integration time on my Seestar S30 Pro. This is a tricky target and I was reluctant to try it but happy with the image quality with such a short integration time! The Bortle 3 skies definitely helped!

I can't believe I managed to resolve Jupiter's red spot with only 4 inches of aperture!

The first image is an extreme crop into my lunar mosaic with separately stacked Jupiter sequences painted in before egress and with egress in-progress.

I hope you like them!

This is my best shot of M16 so far. Taken with a 10” Meade on a Losmandy G11 mount using Antlia 3nm SHO filters and an ASI2600mm pro. I hope you like it.

Captured Jupiter early yesterday morning as I was taking my Seestar back inside. I wasn’t planning on seeing any details. I was pleasantly surprised with what it captured!

Raw video: 25 seconds. Stacked in app.

this was a little experiment. instead of using a traditional narrowband palette, i combined h-alpha, sii, and broadband blue into an hsb composition.

since oiii emission is generally very weak in ic 405, i came up with the idea of using broadband blue instead, hoping to bring out some of the faint blue reflection nebulosity around ae aurigae.

the golden-yellow structures show the emission nebula in a deliberately artistic color palette. a bit unconventional and definitely more work than usual, but i'm pretty happy with how it turned out 😊

The Iris Nebula over two nights at Jordan Lake, North Carolina — my latest Seestar S30 Pro image.

Equipment: Seestar S30 Pro, broadband IRCUT filter, gain 200.

Capture: October 6–7 and October 7–8, 2026, Big Woods Road area at Jordan Lake.

Integration: 722 × 30 seconds = 6 hours 1 minute.

Processing: Siril with the NaZtronomy Smart Telescope script (1× drizzle), crop, plate solving and SPCC; GraXpert background extraction; PixInsight with BlurXTerminator, NoiseXTerminator, StarXTerminator, MultiscaleAdaptiveStretch and gentle local contrast. Stars processed separately and recombined.

I like the blue center against the surrounding dust. Still learning with each image—constructive feedback welcome!

Narrowfield so you can't see the North America shape x)

Fun effect messing with shutter speed and camera movement. Result is striking and I feel like I’m there…

Shoot on dwarf 3, about 90 min exposition

In both the section and the full view of year 5 of the DESI scan, I notice a remarkably intact structure. But if I think about it like RADAR or LiDAR, I would expect to see shadows cast behind objects where light could not reached the scanner. Second question is how could DESI not punch through ANY of what I assume is the plane of the ecliptic that is cause the symmetrical scanning gap in the full view, if a can scan out extremely far in other areas.
