I think there is a risk that we are confusing QuickSilver, who has yet to try any of this stuff in the dark.
There are FOUR devices that might be used to control an Evolution Telescope;...
1. Nexstar + HC (with no Starsense), with or without a SkySync GPS accessory.
2. Starsense HC (obviously with Starsense camera), with or without SkySync GPS accessory.
3. Android/IOS Tablet or Phone using an APP such as SkyPortal or SkySafari. This is usually connected by the Evolution's internal WiFI.
4. Laptop using a Windows 10 application such as CPWI. This is usually connected by the Evolution's internal WiFI or cable.
5. In essence, you can choose only ONE of these control devices and must stick with that device for the whole of that alignment session.
There are some exceptions, but let's not confuse Quicksilver. Let's stick to basics.
In each case <Time> and <Location> (etc.) is stored in the relevant control device.
Hence, if you have saved this in the HC, it won't later be respected by any of the other control devices.
You must enter the data seperately into each device where (last) Location will be remembered (and can only be changed via <Menu>).
a) If using Starsense HC in isolation you need to enter Location once (it then remembers that). Date, Time, Zone and DST must be entered every session.
b) If using SkySync GPS, you don't need to manually enter date and time for each new session. So that is a benefit.
c) However, as regards (3) and (4) you do NOT need GPS as the mount will take that data from <location services> of your tablet or Laptop if connected to the Internet.
Frankly, I agree with Quicksilver that the tablet/APP can be messy and awkward. I found "Pinch & Swipe" inaccurate and Celestron WiFI flakey. But it is a matter of personal preference. Younger folk master a tablet better than older folk. However, I would advocate that whatever control device you favour, learn how to do everything with a Hand Controller. I guarantee that at at some stage you will suffer from having no Internet, or from a computer/tablet/phone failure and regret not knowing how to use a HC. I now use CPWI and laptop, so my expensive SkySync accessory sits redundant. However, I once drove 150 miles to a Dark Sky location where I didn't have a 4G Internet connection and I had forgotten to make a note of my (intended) latitude and longitude before departing. My phone was out of signal range too, and I was 100 miles from my nearest City. It was cloudy all night else I would have been suicidal as I so rarely see clear skies.
