Thank you! Have you encountered any poor wi-fi signal issues or over heating of the devices from stacking Pi 4 over the USB Hub?

Hello,
I was looking for a reliable USB Hub for Pi 4 and came across this thread. Your set up looks nimble! By the way, where did you get those red and blue Pi 4 cases? Thanks!

Hi,
This is helpful. I am about to embark on an astrophotography journey and would appreciate if you could please answer some questions. My apologies in advance if they sound a bit naive.

1) Would I connect a ZWO Guide camera (via USB cable) to the USB hub on the back of ZWO Imaging camera (say ASI 533 MC-P) or directly to a USB hub on RPI 4?
2) Which USB port (between USB 2 and USB 3) on the back of ZWO ASI 533 would connect to which USB port (USB 2 or USB 3) on RPI 4?
3) Was your ASI 294 the cooled version?
4) What sort of cable were you using to power RI 4 and ASI 294 from TalentCell 6000mAh/12V? Would a larger TalentCell 12V/11000mAh be able to handle the power need of a cooled camera and simultaneously power RI 4, Guide Camera, and ZWO EAF?

Many thanks!

Rafa,
Thank you for the battery suggestion. It has positive reviews.

Would you be able to answer a few questions?

1) Are you using RPI power adapter 15 W/3A to power RPI 4 via Baseus 65 W and you have ASI 533MC-P, ASI 120 MM-S, and ON Step Mount connected to various USB ports on RPI 4?
2) You said that you were using the second Baseus 65 W to cool the ASI 533 MC-P. My understanding was such cooling requires a DC 12 V/3-5A power through the DC 12 V port on the back of the camera? How are you using Baseus 65 W and what kind of cable to cool ASI 533 MC-P? Baseus's various USB ports supply 20 V1.5 A and 20 V/3A power. Wouldn't 20 V be above the recommended power supply of 12 V for ASI 533MC-P?

Thanks in advance!
