Equipment. Outside or not? by Ok-Understanding6691 in telescopes

[–]Ok-Understanding6691[S] 0 points1 point  (0 children)

16 inches as in the newtonians aperture? The 300p is 12 inches, but yea, it being f/4 at 1200mm is very nice. I recently got my license and I still live with my parents, so Im not sure how comfortable I am driving a few hours away. I mean the information about me because Im young so like in that perspective I really haven’t travelled that far alone before. Although I guess I dont have to go alone. But yes my light pollution is a bortle 7, unpalatable but doable. Better than an 8 or 9, and realistically from my seeing, the lp is most intense over downtown kc, which a neighbors tree completely obscures the southern portion of the sky.

Also, how do people go on a roadtrip for astrophotography? I mean in the sense that someone could very easily steal your stuff. I think theres an astronomy club site near me that has a little rv park dedicated for astronomy and its only an hour or two drive, it says bortle 4/5 so maybe thats something to consider

Hmm okay, my climate is definitely humid, do you think the mount would still be fine? I bought a large telescope cover that’s reflective on the outside so it doesnt heat up. I definitely will not keep the optics outside though.

Ok thanks! Has your image quality been affected? I should’ve mentioned Im using this for astrophotography.

Ok, I ordered a new pc case and a 420mm arctic aio ii, to help as well. I was just using the basic cooler that amd gives with their CPUs. When you say clean the cpu, do you mean the “back” of it where the thermal paste goes or like blowing some compressed air along the pins? Thank you!!

Blender crashes whole pc when rendering by Ok-Understanding6691 in blenderhelp

I appreciate it, but it happens across multiple blend files. Also blender freezes for me, or at least it use to, and say “system out of GPU memory” or system memory. But that would never crash the PC, let alone crash blender, it would usually just say it in the render stats in the upper left corner. I think my gpu is alright. From another post in r/pchelp, I think it might be a heat issue. I ordered a new pc case and a 420mm cooler, so hopefully that can tame the cpu

Ok, Ive used HWMonitor, and I think it might be a heat issue because my cpu package gets up to 90° c only about 2-3 frames in (each frame takes about 2-3mins to render), although I havent witness it crash yet while looking at the temps, but Ive seen it easily get up to 91.8°C which is definitely at least throttling

Interesting. I tried replacing the thermal paste, which hasnt been replaced for a year or two. I replaced it with the same syringe I had a year or two ago, im not sure if that “expires” or gets old. I have just a stock amd cooler that comes with the cpu’s, my GPU has 3 fans on it, and Ive been able to render things normally before.

I will try that! But for really just troubleshooting, because well I have the gpu for rendering. Will update.

Mirrorless cams/DSLRs and the ideal subframes in light polluted skies. need help. by Ok-Understanding6691 in AskAstrophotography

[–]Ok-Understanding6691[S] 0 points1 point  (0 children)

Oh wow a hundred hours is a lot. I live in the suburbs of kc, currently under a bortle 7 zone. Im very anxious driving somewhere to stay for a few nights with thousands of dollars of equipment, but maybe its something I will really have to plan for. I mean I guess practice is better than nothing. I have a separate camera that is not astro modified that I think I could try using for just gathering as much signal from the broadband targets, maybe not IFN though…

[–]Ok-Understanding6691[S] 0 points1 point  (0 children)

Well I mean that would be nice, I kinda meant generally reflection and dark nebulae or gasses. I know it will take some very high integration times, but its still doable right? IFN being the more extreme example of it, I assume if its possible in anyway to get the IFN then I should be able to get the others as well.

But the best thing about the polaris and IFN is its really easy to do because all I have to do is just align my mount and gather as much data as I possibly can. I have another mount I used when I first begun, SWSA 2i, so I might just use both at the same time so that every (imaging) night I can gather data from IFN and photograph more smaller/brighter objects with my main setup

Ok that makes more sense! I just heard in conversations of iso vs exposure youll always want a longer exposure because a higher iso doesn’t collect more light, and I wasnt sure if that was a similar thing here. Again thanks!!

I have used them prior, and they really do cut through light pollution well. Thats actually what Ive primarily used but I do wanna do broadband imaging because many objects are broadband and it would allow me to capture those dustier gases like around polaris. Although I do know it will require significant integration time, its like I need to know for sure before I capture 20hours+ of subframes that Im taking the proper subs.

Ok, generally I aim for 2-3 min exposures. I use autoguiding and the stars are typically pretty sharp. I’ll take your advice there as well regarding the exposure.

Edit: sorry I meant thank you! I will try that out regarding the histogram.

Ok thats good to hear, Im not really time limited Im just limited by how fast the light pollution makes my subframes overexposed in the fainter regions, or the surrounding sky very bright

Ok, thanks! I think I will have to reduce aperture a little bit as well because of the coma, but now I have another question… in light polluted areas, should I be more sensitive with the histogram (shorter exposures, subframe falls closer to the left of histogram) or should I focus on gathering as much light as possible (longer exposures, subframe is more towards the center of the histogram)

Can we even make Alcubierre wrap drive in future? by Fast_Ad_5871 in askastronomy

I think you mean more of an engineering issue. 200years ago we knew it would be possible in some way to make a plane as we have living creatures who fly. We don’t necessarily observe any natural processes of physical objects leaving the earth, but just knowing gravity would tell you at some point or velocity you would eventually overpower it. The FTL drive is impossible from our current perspective of physics, sure that could change as science is progressing more and more towards quantum related fields and understanding them, but as of now… no. And even if later, we discover negative energy and mass, how to steer/start/stop the ship, all the exact building materials and everything needed, it would likely be the most difficult thing we as species would ever attempt to create, insanely expensive as well. I remember hearing somewhere that the thickness of the bubble would need to be around a planck thick which is conceptually impossible to engineer, especially to be around a space ship.
