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?

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.

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.

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?

Seestar 30P, Bortle 6.7, used NINA to capture. 30x10sec, 50x60sec processed in Siril LR mobile for masks and coloring.

First time capturing this with having only one good late night (last night the fog rolled in). I'm still shooting for 4hrs of integration time but I've got a good base to build off of.

The beautiful Double Cluster! These two star clusters are NGC 869 and NGC 884. They are about 7,000 light-years away and only separated by a few hundred light-years. Estimated to be about 13 million years old!

Telescope: Seestar S50
Integration time: 1 hour (it's a 2-panel mosaic, so 1 hour on each panel)
Tools used: Siril, GraXpert, GIMP
Script mentions: DeepSNR, HDR_multiscale, VeraLux (Revela & Curves)
Bortle 8-9

I posted this about a month ago, but since then, I went back and made a few tweaks I'm happy with:

- Fine rotation to square the diffraction spikes

- Star reduction

- Better background extraction / noise reduction

- Saturation adjustments

- Stretches to make the core a bit brighter than the outer disk

- Rejecting streaked frames

Gear:

• Orion 6" f/4 astrograph

• Baader Mark III multi-purpose coma corrector

• Astromania UV/IR cut filter

• ZWO ASI184MC OSC uncooled

• Celestron Advanced GT equatorial mount

Acquisition: Bortle 1-2 site with no moon

• Approx. 120 x 60s subs, 300 gain, in SharpCap

• No guiding

• 10 x 60s darks

• 100 flats

• 100 biases

Processing: All in Siril

• OSC preprocessing script to stack and align, with filter added to skip frames with roundness score under 0.5

• Background extraction

• Spectrophotometric color calibration

• GHS transformation

• Star reduction

• Black point adjustment

• Saturation
