I was wondering how you guys manage power supply with your iAstrohub.
I am going to use a low profile setup. Only iAH, a Canon DSLR attached to an Astrotrac mount. I have a 12V battery or alternatively a 10Ah Powerbank.
The Powerbank would provide 12V for the mount and 5V for iAH. Would that be enough? Or would you go for a powered USB by as well?
In case I use the 12V battery I guess I need some sort of DCDC converter to have 5V for iAH. Is that right? Are there any 12V USB hubs you can recommend?
Thanks for all comments!
If you just have iAH and the DSLR connected, you should be fine with 12V. I use a 12V USB connected (like those you might use in your car via the cigarette lighter socket) to iAH. The DSLR has it's own battery so shouldn't need to draw much power from the iAH device.
I find that the single 5V USB is enough if just using the DSLR, but as soon as I add the QHY guide camera I need more power so I have a USB powered hub which also runs from the car USB adapter. If you use end up using one of these, try to get one that provides at least 1 amp, preferably 1.5 or 2 amps. Mine is a dual USB port providing 1.5 amps per port which works great.
Hope that helps,
