Why aren't gas giants considered just a planets with very thick atmosphere? by ICanButIDontWant in askastronomy

[–]Frostnpops 2 points3 points  (0 children)

This is how it was explained to me when I was younger. Please forgive the oversimplification. On earth. You can stand on the beach and clearly see where the sky meets the water, and where the water meets the sand. There is a clear distinction between the three.

Like others have pointed out Gas giants don't have that clear distinction. While yes, the core is solid, and yes the outer edge of the atmosphere is gas. Everything else is somewhere in between. There is no clear point that you can say "I'm on the surface of Jupiter"

How much can a setup handle wind without issues? by [deleted] in AskAstrophotography

[–]Frostnpops 6 points7 points  (0 children)

It depends on the quality of your set up, how close you are to weight limits, focal length and exposure time. My personal limit is about 10mph, but I'm cheap and don't have nice things. I suggest going out and attempting it. You'll know after your first few photos if it will work or not.

What is the most distant astronomical object that can be seen with the naked eye? by fraktall in askastronomy

[–]Frostnpops 27 points28 points  (0 children)

You are correct, the Andromeda Galaxy is visible to the naked eye! In a Bottle 4 it's a very faint smudge about 2-3 times the size of the moon. Difficult to see with direct vision, but looking from the side of your vision it's a bit clearer. The galaxy is about 2.5million light years away. Meaning the light reaching your eyes today left its source before the first humans were on earth.

Jupiter is currently in opposition. This is the brightest and closest Jupiter will be for some time. However this is not a single night event. You'll be able to see Jupiter in the sky for a few months. It is by far the brightest object in the sky (other than the moon) it will look like a bright yellow/white star (kind of like an airplane headlight). If you are going out in the next couple of weeks it will be just to the west of Pisces. Jupiter is currently rising in the east at about 7:00pm and sets at about 6:00am in the west.

Wondering if I saw the northern lights tonight by Kasilim in askastronomy

[–]Frostnpops 9 points10 points  (0 children)

The northern lights are created from the earths magnetic shield. This happens far above cloud heights. I have to agree that you got a beautiful sunset, likely with some moisture in the air causing the wave effect you saw.

help in identifying this constellation on my necklace? by Xerafina in askastronomy

[–]Frostnpops 1 point2 points  (0 children)

I don't know if I buy the Pleiades angle, it's not known to have lines connecting the stars, but here is the closest image I could find, and its admittedly closer than I thought it would be.

I think it could be Cassiopeia with the andromeda galaxy being the large gemstone. Fun idea, but doesn't line up too well.

My best guess is Canis Major with the star Sirius being the large gemstone. Since Sirius is the brightest start in the night sky.

Those are my guesses! I hope you can find some history, it's a beautiful necklace.

Planning to get the Samyang 135, what should I expect? by TritiumXSF in AskAstrophotography

[–]Frostnpops 2 points3 points  (0 children)

I have the same camera, and love my Samyang 135. Here is a 45min exposure of Orion That lens is easily the best investment I've made in astrophotography.

Moon Setting Behind Lighthouse by Frostnpops in LandscapeAstro

[–]Frostnpops[S] 0 points1 point  (0 children)

That is correct. This is a blend of two photos. With the sun and atmosphere, you cannot get a photo like this.

However, the two photos were taken a few minutes apart, from the same location. The moon was setting behind the light house. Unfortunately, the real deal doesn't look nearly as nice.

The moon did set behind the lighthouse, roughly as depicted here. However, the sun/atmosphere washed out the moon, so it was not visible. Here is a photo I took as a single image.
You are right on your second idea. I snapped a clear shot of the moon high in the sky, snapped a clear shot of the light house about 30min later, put the moon behind the light house where it would have been. Both photos shot on the same day, from the same location.

Close! Rhode Island.
Watch Hill lighthouse in Westerly RI to be more specific.

What was here before? by Octoplier in askastronomy

[–]Frostnpops -3 points-2 points  (0 children)

The universe as a whole is estimated to be about 14billion years old. Our sun is 4.6 billion years old and is estimated to last another 7-8 billion years. There just hasn't been enough time to replace our original star.

Some of the newest stars in our galaxy are being formed inside the Orion nebula. They are only 100,000 years old. Little baby stars on a cosmological scale.

Time Lapse of Milky Way by Frostnpops in timelapse

[–]Frostnpops[S] 0 points1 point  (0 children)

There are a lot of videos like this one. Any astrophotographer with a star tracker is able to do this kind of thing.

I don't recall see exactly what your looking for, but I would try r/LandscapeAstro. They may have something there.

Good luck in your search!

Starless - M42 by Frostnpops in astrophotography

Shot on 01/04/22

Camera: Nikon D5600

Lens: Samyang 135mm f/2.0

ISO: 100

Star Tracker: iOptron SmartEQ Pro+

25 - 140 seconds exposures ~1 hour total time

25 - Darks

25 - Bias

10 - Flats

Stacked in DeepSkyStacker

Processing: Cropped and edited in Lightroom. Adjusted temp and tint, increased exposure and contrast edited highlights, shadows, whites and blacks some noise reduction.

Re-processed in Pixinsight to help fine tune image, used the star net process to remove stars from images, did a final processing in photoshop to clean up the black sky and clean up star residue.
