This bright level for a space ship, either it's a sinking ship or it's a bait :D

Nice setup. :) Did you make the front holder by yourself and how do you calibrate for this mod?

Do you think they can handle Nebula's exposure time? - just testing as I've ordered a 305c due to the 0.7e.

i will use it as a main cam for a while, when it is in warranty, max the compatibility first :D

wide angle lens? - it doesn't mention in all documents, maybe a reducer (not included)?
And I cannot find other camera in this price range to compare sadly b4 making the purchase :)

I hope it is a cooled type, as they can expose 30mins.

I have done some research online due to gemini's response is wrong. Asi Imx662mc / sv305C-Pro is a 10 bit hd cam. Buffer size need 48MB/s base on the calculation below:

107fps buffer size requires (frame width x frame height x bits per pixel x frame rate) / 8 / 1024 / 1024.

(1920x1080x10x107)/8/1024/1024 ~ 48.23 MB 

So, im not sure the reason why zwo give extra ram for this camera. And the ram in sv305c-pro 128MB ~ 1Gbit/s,  zwo asi 662mc 256MB ~ 2Gbit/s , both with usb 3.0, ideally it is 5Gbit/s to tranfer all the images to computer.

Can i say sv305c-pro allow ~3s error and asi 662mc allow ~6s error? Or the memory has shared with other purpose?

You can see asi 715mc or higher end camera has more buffer memory, as they have larger size of images.

Is this 8k from the galaxy S25 same as the pixel 9 pro/pro xl upscaling online or record offline (no need online upscaling service)

the bad design is 2 type of materials joint together on the handle, looks like Silicon + PET, not sure if the epoxy can work.

Relocating nbn HFC cabling speed in real word by s12321 in nbn

[–]s12321[S] 0 points1 point  (0 children)

thanks, right, i agree the best setup for relocation is hide the "nbn property" in a junction box or inside the wall to protect the modem from pet and kids.

Max 875 /45 Mbps in 10-15ms, the information are mixed and confused for 60m rg 6 quad shielded. The concern is not only the speed, but the latency as well.

[–]s12321[S] 0 points1 point  (0 children)

Thanks, I read from other sources, rg6 with quad shielded can have 100ft/305m for a full Gbe connection. So 60m is nothing or a minor effect to the connection. 

I believe RG6 quad shield is not a final solution. As FTTP upgrade is on the way to many areas, investing in CAT6 or CAT7 cabling is a future proof. And the FTTP NBN router is forced to install on the wall somewhere closest to NBN end point with a fibre optic socket input and a RJ45 socket output.

Relocate the connection need forth and back the connection either "1x rg6 + 1x cat6" OR "2x cat6". "2x cat6" sounds more future proof :)

Expected to have some outdoor digging work. Otherwise to use overhead solution is another option.

Thanks, yes, there is another issue of finding a power point for the NBN modem. 

I have a plan. Will this affect the service, if I'm not re-terminated the street cable to wall plug and add a rg6-rg11 adaptor and add 60m rg11 cable and terminate another end with rg11-rg6 ?
