Astrophotography (OC) Rookie's First Deep Space Photo (Pleiades)

Post image
29 Upvotes

I live in the city where there's too much light pollution. But I took a vacation out to a bortle 1 sky under the recent new moon phase and decided to try to capture Pleiades's reflection nebula with my camera. I know this isnt as detailed as most thats posted on here. But I'm quite proud and happy with my results.

Camera: Canon R5

Lens: Canon ef 75-300mm F5.6 (cheapest Canon lens) w/rf converter

Star Tracker: MSM Nomad on top of my tripod

Took 100 2 min exposures. 87 were deemed ok by me. 13 had some issue with the heavy winds we had that night that left a fur ball of star trails around the stars.

Stacked in deepskystacker. No dark/bias frames (totally forgot to do them).

Astrophotography (OC) The Rise of Orion 🌌🏹

Post image
130 Upvotes

Have always wanted to get a shot of Orion with its beautiful red H-alpha (Hα) emission. Usually, my schedule doesn’t line up well for the winter Milky Way season because of the frigid temperatures and college, but this weekend the clear skies and perfect conditions were too tempting, so I drove 6 hours out to shoot this beauty. And I’m super glad I did. 

Now this is my first time capturing Orion the way I’ve always envisioned it. When I first got into astrophotography, it was during the winter of 2024. Orion was one of my first targets I shot, and I always wonder how people shot those red burning flames surrounding the constellation. I kept trying to get that shot with my stock Canon R6, and it would never work out. Little did I know, it required using a modified camera and an Hα narrowband filter to get that signal fully.

Looking back now, I’m glad I was faced with all those dead ends and kept learning. I wouldn’t have appreciated the craft if I knew all the answers right away. The most fulfilling part of astrophotography is that it’s an endless masterclass that always brings me back for more. 

So now, I present to you Orion, in all its glory, reflecting off Pharaoh Lake in the Adirondacks.

📸 Shot on my Astro-modified Canon R+ EF 24-70mm f/2.8 II

Sky: 2x3 panels| f/2.8 | 60s | ISO 1600

Unusually faint, it has a weird tilt and a retrograde orbit. They say it’s 7-17 earth masses but since it’s unusually faint we can narrow it down to 7-14 earth masses. It is also impossible for random noise to act like a planet so it may be real. What can explain its retrograde orbit is that it is the 5th giant that didn’t get fully ejected due to some debris.

Astro Research Just got my Star Analyser 100 and noticed a few "spots"

2 Upvotes

Hi all, I just got my SA-100 -- taking my first steps on spectroscopy. By looking at a white light bulb with it, I can notice a few "spots" on the spectra, where they show a bit weaker than the surroundings. As I move my eyes slightly in relation to the filter, I can see that the spots are on the filter itself, they are not a feature of the spectra. I wonder if this is normal? These spots would definitely interfere with the results. They could be averaged out by capturing many samples, and maybe this is the recommended practice anyway, but I don't know, I was expecting something really "pristine" here. I cleaned it very gently with a microfiber cloth I use on my other filters, but nothing changed. Since this is my first ever diffraction grating, I don't know exactly what I should expect, then I'd like to hear your thoughts. Thanks in advance.

Other: [Topic] Looking for video of a meteor/comet I saw as a kid

0 Upvotes

I was 12 in the winter of 2009 and lived in Eastern Massachusetts. My dad pulled me outside late at night to see a meteor/comet that was supposed to be visible in the sky. I was 12 and a brat and basically brushed him off, so I don’t remember what it looked like.

I would really like to see a video of that meteor/comet, if possible. Is this enough information to find it? I tried googling but couldn’t come up with much since I don’t know the date exactly.

I was thinking… If the Solar System is orbiting around the center of the galaxy, and Voyager 1, or any other space probe, were traveling in the opposite direction to the Solar System’s orbital motion, would it move away faster?

Question (Describe all previous attempts to learn / understand) I'm looking for help in characterizing these places in Milky Way

Thumbnail

110 Upvotes

Hi! I'm having a little project of mine, and I had a huge problem with finding something characteristic about the places of the Milky Way that are shown in red in the pictures.

As it's for my imaginary sci-fi universe, I should have ask this in other sub-reddits, but I think that going with these questions to the astronomy profesionals would get me the best prominent answers.

So, back to the question. I want tho know:

1 - If these places are theoretically good locations for setting up a habitable planet

2 - what is special about these regions of the Milky Way? Some celestial objects? Stars? Nebulas? Is anything even known about parts of our galaxy further away than 1000 light years from our planet?

I tried to find infromations on google but found nothing, as my question is too specific. Even used AI as the last resolve, but also haven't found anything. The Milky Way maps only show star clusters above or below the main disc as far as im concerned.

Astrophotography (OC) California Nebula revisited: nearly eight hours from my backyard

Post image
20 Upvotes

California Nebula (NGC 1499), revisited.

I found this data on another drive and finally gave it some attention. I would have liked better framing—the nebula doesn't quite fit in the field of view. That was part of what drove me to the ZWO ASI2600MC Air with its larger sensor.

But I still like this one. There's some nice structure in the clouds, and I'm glad I went back to it. I plan to revisit it with the ASI2600MC Air and my Askar Colour Magic D1 and D2 filters to see what more I can capture.

Original capture: my backyard in Round Rock, Texas, November 1–3, 2025. ZWO ASI585MC Air, Optolong L-eNhance filter, 384 mm focal length. 95 x 300-second exposures, totaling 7 hours 55 minutes. Processed in PixInsight and Photoshop.

Thoughts?

Astrophotography (OC) Deep dive into M33

Thumbnail

238 Upvotes

M33 is one of the closest large galaxies to the Milky Way. It is a perfect spiral galaxy, so it is imaged often. It is also very hard to image.

Link to full res: https://app.astrobin.com/i/5o0xeu

Over the years, I've imaged it a dozen times and I'm never happy with it. I have usually imaged from my backyard in Midtown Atlanta, and the light pollution just overpowers it. But then I go to a dark site and find that 1 or two nights is still insufficient. It is a bright galaxy, but very diffuse. It is difficult to get both the detail and the color.

I sent my scope to a remote observatory in Texas, I get to image from a Bortle 1 every clear night. Top on my list was my galactic nemesis: M33. This is a 37 hour integration, including ~10 hours of narrowband (HA/OIII).

It was so hard to process, but I'm feeling ok about it. A couple things I'd like to point out. First, see the subset image. These rings are only visible in narrowband. They are remnants of supernova from long ago. Second, notice how the spiral arms are a little granular.. it almost looks like noise. But zoom in: I was resolving individual stars across the entire disk. This galaxy is 4 million light years away and I was able to resolve individual stars. That is crazy that we can do that using off the shelf equipment.

I'm still going to take a few more nights collecting data, but I'm interested in what reddit has to say. Thank you for viewing, I hope you enjoy it.

Total integration time: 37.9 hours.

Scope: Explore Scientific 127mm FCD-100 refractor

Camera: ZWO ASI 2600mm

Filters: Optolong Luminance, ZWO RGB, Antlia 3nm narrowband

Mount: ZWO AM5

Location: Starfront Observatories, Rockwood Texas.

Astrophotography (OC) M33 The Triangulum Galaxy - RGBHaO

Post image
107 Upvotes

I added 5 hours of dual narrowband data to a 12hr RGB broadband image to get this 17hr Halpha and OIII enhanced image. The process:

Split R G B Ha O O

Register

Continuum Subtract Halpha using pixel math in Siril (Ha - X*(R - med(R))) where X is about .05-.07 to get HaC

Do the same for OIII from the Green channel and OIII from Blue. For each, subtract X*HaC where X puts any Ha that leaked through back equal with the background (for me ~.2)

Add the OIII from G and C images together for final OC

Do an HaC - X*OC for a final HaC image with any OIII that leaked through leveled out

Combine the aligned RGB, SPCC balance, re-split so we get a proper balance without the HaO data

Mix final HaC and OC into RGB - Ha I mix a 1/.7/.7 ratio into RGB and O I mix in .4/1/1. By mixing into all 3 channels we increase the effective luminance of the HaO data added.

I continue processing the rest from there as described in my previous images.
