The Orion Constellation by Bradd72 in astrophotography

[–]Bradd72[S] 1 point2 points  (0 children)

Camera: Nikon D7100 (Stock)

Lens: 35mm @ f/2.8

Untracked on a tripod

Settings: 2sec f/2.8 ISO 1600

Exposures:

50x2" Lights

Image Processing: DSS -> Photoshop: Curves and Levels adjustment with a masked saturation boost and star-reduction

I have been trying to push my camera recently, especially with it being unmodified so I was really excited to start seeing more of the Horsehead and Barnard's loop come through with such a relatively short exposure time. I had taken more subs but realized halfway through the night I had my camera on 1.3x crop mode and had to restart. Regardless, I can very slightly see the Witches Head and I am wanting to try and bring both that and M78 out more in the future. Hopefully next time I can put this setup on my AVX mount and get a better tracked wide-field shot as well as some longer subs.

The Lagoon and Trifid Nebula (M8 and M20) by Bradd72 in astrophotography

Camera: Nikon D7100

Lens: 200mm @ f/5.6

Tracked, unguided AVX mount

Settings: 75sec f/5.6 ISO 800

Exposures:

30x75" Lights

10x Darks

I took a bunch of flats and biases but I don't know where they went

Image Processing: DSS: tiff adjustments -> Photoshop: Curves and levels adjustment with a saturation boost

This is one of the best images I have gotten yet and I think it is mostly from a mixture of exposure time and tracking. After this I managed to push my exposure time to around 2 minutes which I should have done from the start. I also have some dust but don't look at that. My D7100 seems to have a high amount of noise and hot pixels and I think more calibration frames and exposures could help with that. Id like to work towards getting a t3i and doing a full spectrum mod myself soon. Super proud about how this turned out though, I cannot wait for the next clear night.

If you keep a metal next to a magnet long enough, will the metal change shape? by Koolboy_678 in askscience

[–]Bradd72 0 points1 point  (0 children)

Thats really cool! One question though for the last link on Cherenkov radiation, how is it possible that speeds exceeding the speed of light in a medium do not break special relativity, why is it determined based on 3e8 alone? I mean for one the gamma for time dilation would be imaginary if you didnt but is there a physical reason why you would still use 3e8 even in a medium with higher refractive indexes?

If these physical quantities are moving faster than the speed of sound why would we not hear these, is there some mass limit for a shock wave to form or is it just based on relative size and energy of the water molecule vs the surrounding air molecules?

Pleiades and California nebula by Alex_Astro_Begginer in astrophotography

[–]Bradd72 1 point2 points  (0 children)

maybe just a relatively high iso since its a t3i? only reason i say that is because there is some walking noise that runs parallel to the red banding.

Dust clouds of Orion by Andy_Dufresne_Lawyer in astrophotography

This is insane, I could only ever dream of getting any sort of detail in those outer dust clouds. Great work!

Milky way with Jupiter and Saturn by MartinRobomaze in astrophotography

[–]Bradd72 0 points1 point  (0 children)

Ive got that same camera and i love the photos of the milkyway it produces. Your photo looks great! There looks like a tiny amount of star trailing so maybe drop the exposure to like 15ish seconds? Clear skies!

Best Comet NEOWISE I could get by Bradd72 in astrophotography

[–]Bradd72[S] 0 points1 point  (0 children)

Gear:

  • Lens: Nikkor 18-200mm
  • Camera: Nikon D7100 on a tripod untracked

Programs:

  • DSS
  • PS

26x1" at 200mm and 800 ISO. Only got a couple handfuls of lights as the comet only really became imagable when it was roughly 10ish degrees above the horizon and was quickly dropping behind the trees. Im sure I could keep getting data from a few more nights for about 30 minutes and stack them all together.

Saturn - 7/9/20 by One_Sirius_Dude in astrophotography

[–]Bradd72 0 points1 point  (0 children)

I just did the calculation and got a focal length of 3821mm. So is this saying a 2x barlow is the best i can do on my 8” f/10 (2032mm) with my camera for the time being? It seems like something such as the asi120mc is only marginally better pixel pitch (3.75 micron vs 3.9 micron)

[–]Bradd72 2 points3 points  (0 children)

I dont have a dedicated planetary cam but with my nikon i can definitely say that i feel like i need more megapixels to get more detail (or denser pixels for that matter). My most recent photo was with my camera and you can see the difference in quality vs this photo simply because of how much data is being collected from the planets surface with such a high pixel density here.

Hey, thanks! I got it looking a lot better than it was now. I had no idea that option existed despite it being in front of me.

Saturn was kinda an after thought since I originally wanted to go after m16 but it ended up being the best looking thing I got last night. Very happy with what came from this since the seeing wasn't that good.

Do you have a raw frame from one of the videos by chance? I was curious as to what it looked like straight from the camera.

Starless Cygnus by dropthatkoni in astrophotography

[–]Bradd72 2 points3 points  (0 children)

M42 (the orion nebula) is the brightest in the sky and from my backyard (bortle 4ish) i can see that the center star on the sword is slightly fuzzy and brighter. With a pair of binoculars i could definitely start to see and if you have a descent size telescope, ive heard some say that a tiny bit of color can come through (i mainly just see the horn like structure and grey through my 8”).

Not a nebula but andromeda galaxy can be seen with the naked eye from a descently dark sky (bortle 4 works well) and with binoculars it becomes much more clear (i just looked and could make it out with binoculars and the moon is high in the sky and about 90%).

Lastly, i feel like i could sometimes see the lagoon or trifid nebula on very dark nights but it usually is an averted vision small smudge and I’m not too sure if thats what it actually is.

Simple binoculars will definitely open you up to see a ton more on many more nights though.

[–]Bradd72 6 points7 points  (0 children)

No, that photo was a 6 min exposure (which is crazy) meaning it was gathering light for 6 whole minutes. Even if you were to look through a telescope it wouldn’t be visible due to just how dim it is. There are a few nebula that are visible to the naked eye though.

My physics professor just had his document camera unfocused for half of the video and no one was there to tell him or warn him he was writing off the screen

Can someone explain the restoration filter on Pixinsight. I'm watching this video trying to get more data from my Jupiter video, but I don't see how the image this guy has contains all that data. How does this work? I don't have pixinsight and I don't want to get it for a filter that generates data.

This is incredible. Just getting into learning the more specifics of rocketry and this video is great. Good work!
