That makes sense.

Thanks,

Hi Rolando,

I thought location (as well as clock) was used for the first slew to a known object or star after unparking from one of four park positions. So, I normally set the mount to Park 4, power up the mount, unpark from Park 4, and slew to a star or object. So location data (as well as clock) is irrelevant for this case?

I know that subsequent slews after RCAL, clock and location are irrelevant. But isn't the very first slew after unparking from a known park position is dependent on clock and location?

It has absolutely no significance. GoTos are not regulated by observer location. Never has been. You can tell it that you're in Bangalore and as long as you tell it that it's 8pm daylight savings (if that's what time it is where you are) and center/r ecal on the first star, the mount servo will happily slew exactly to the next object and the next, etc. It won't care where you told it that you are located. The meridian flips are based on hour angle, same as the horizon limits east and west.


I'm not sure what the implications are of this slightly wrong longitude, so what if anything will that affect. Presumably my GOTOs and meridian flip times will be very slightly out,

Hi Rolando,
That is one of the first things I checked, but only locations 1 and 2 are set and both have the identical correct settings. Locations 3-9 are all 0000's. So far I have not found anywhere that holds the reported wrong longitude, so its very curious. I will try your suggestion to start with autoconnect NO and specify the correct location to see if that fixes it. I'm not sure what the implications are of this slightly wrong longitude, so what if anything will that affect. Presumably my GOTOs and meridian flip times will be very slightly out, which is not much of an issue, but is there anything else I should be aware off?

You may have set the bogus setting in another location (Location2 perhaps?) When you set your keypad to YES, it used the last location that you had set, the bogus one. You might want to check your location number and start your keypad with Autoconnect NO for the first time and specify the proper location. Then you can set it to YES and have the keypad automatically start from that proper location.

Thanks Rolando,
As per the images that I uploaded to my Dropbox folder the site settings in the V2 driver and the HC are the same, but when I have the HC connected as well as the V2 driver the V2 driver reports a different Mount Actual position. See images at link below...

V2 site set up and HC site both show correct longitude as E 01 06 13.0, BUT with the HC connected the Mount Actual is being reported in the V2 driver as E 00 53 02.0, which is in the middle of a farm some 10 miles away, where I have never been....!!

Here is the answer from our software engineer:

I cannot explain. Is the setting in the HC correct for the site he is at, and is the correct site chosen?

I have never heard of a case where the HC sent something different to the mount than what HC site setting says to send.


Mike can you explain why the HC sets the longitude differently?

Thanks Ray,

Ok so I powered everything down including the laptop, disconnected the HC then powered everything up and connected the V2 driver using the PHD2 client. As you advised the V2 driver then reported the correct Mount Actual and Site settings both the same. So I powered everything off again, reconnected the HC and powered up again, then reconnected the V2 driver via PHD2 and am back where I was was with the same incorrect Mount Actual longitude setting, so I still have no idea how/where that is being set in the mount.

Hi George,

If you are following this please could explain how I can get the correct longitude settting in the mount via the HC. I have no idea how it became wrong in the first place.

Geof

Geof,

> Please explain 'initialize mount' more fully. Is this just turning on the power supply?

After turning on the mount, you can initialize it with the AP V2 driver by starting any ASCOM client application that uses the
driver. When the driver connects to the mount it will initialize it, but you might want to be wary of the park/unpark settings.
Typically you want to unpark from last parked position, and park to one of the AP park positions.

You can find information about how to set the driver's initialization values in the help file, and also online here:

http://www.gralak.com/apdriver/help/index.html?telescope_setup.htm http://www.gralak.com/apdriver/help/index.html?telescope_setup.htm

> Also what if I just want to use the HC not connect to a laptop at all?

That's something that maybe George, Howard, or Roland might be better at describing as I very rarely use the hand controller.
