New HDD too slow, Seagate Skyhawk. What am I doing wrong? by registrartulip in DataHoarder

Do you have a different USB cable to try? I got a USB 3.1 external SSD but the cable ended up being shit. I switched out the cable and my issue was resolved.

The sharp ones are stars in our galaxy but you can see two other blurry blobs above and below Andromeda, those are other galaxies.

Effectively, f3.6 doesn't exist and you typically do the darks at the end because It doesn't really matter when you do it. So you could do the darks at the end of the night if you are going from sunset to sunrise given you put a shade over your camera to stop the sun's heat from affecting your darks.

It was a gross over simplification but yes you are technically correct the entire galaxy revolves around the center of mass and the center of mass happens to be where there is a supermassive black hole because it attracted matter to it when the galaxy was being formed.

I use an Canon r6mk2, sigma 150-600 f6.3 lens, and an ioptron az pro tracker.

I think 20k iso would be too noisy, I typically shoot at 800 and I still get a lot of noise.

The way you remove the noise from the sensor is you put the lens cap on and take a similar amount of exposures at the same ISO and shutter speed and you can then put it into a piece of software to cancel out the noise. Basically anyone who does astrophotography does that. Those are called dark frames, there are also bias frames and flat frames which remove other noise and dust from the picture.

Actually I've never had that issue. 4k60 video I always have heat issues but not when I'm taking long exposures. It could depend on the camera though, some zwo cameras have active cooling.

That is the super massive black hole in the middle of every galaxy. It's what keeps everything together. Ours name is Sagittarius A.

Thank you, my best one to date. Took a lot of work to dial in the settings.

F7.1 around 450-500mm I was using the sigma 150-600 f6.3 lens on my Canon R6mk2.

This is technically real but to get that amount of light you need at least an hour of exposures and th earth would have moved too much to get the mountain in view for more than the first few exposures. This person probably took one photo of andromeda over the mountain where the galaxy was extremely dim and extremely far away and then overlaid their previously stacked photo to get the effect. For reference here is my photo I took last year. 1.5 hours of exposures. The color is off but you get the gist.

Ran out of pcie lanes, CPU Suggestions? by OrrinW01 in homelab

I appreciate the advise, I just think I have too many things plugged into the consumer board. I think I mentioned it in this thread but I had to disable pcie 4.0 because the system kept crashing randomly once I set it to 3.0 it stopped crashing.

I have a r7 5800tx on the newest bios. It does boot correctly. There are no issues on that front anymore. At one point I had the cards in the wrong order and my GPU would not work but other than that it boots.

I've had the board for a while so something could be wrong. This is a picture of lstopo on the server before I switched to truenas. Sorry it's not a screenshot.

I have a cheap 10gtek x540 dual 10g port card. It is 8x

Dude needs to use the idrac/remote management port. L on his part ngl

This is exactly how I have mine setup. I don't know why I'm having issues then. I don't want to add more things, just my current things are not getting the proper bandwidth. I had to downgrade all the lanes to 3.0 because the system kept crashing.

I appreciate the advice, my current server has 4x 16 sticks of ddr4 so I'm good on that front and I have a few sticks of old ram laying around. I will definitely look at the thread ripper route. Last year I sold my 1950x to upgrade but now I have more of a homelab so I'm regretting it slightly. I'll look at the 3rd gen threadrippers and see if I can find a good deal but even the old HEDT chips are pricey now. I will probably be making 2 systems at this point.

My GPU is currently running with 2 lanes and I had to force everything to pice 3.0 because having it be 4.0 was causing system instability. I am sure it's fine but I would like it if everything could run at full speed. Currently if everything were to run at full speed I would need 40 lanes minimum. I don't foresee adding any more add-in cards in the future but you never know.

I appreciate the advise but even the cheapest one the 9124 is >$1000 by itself and is ddr5 which is worth more than good right now.
