NEVER?

If the PC or laptop can be connected to a network every few days (maybe with a wi-fi dongle), the network time sync software could accurately set it then. Most PC clocks are good enough to maintain fairly accurate time over several days.

Or, as The he said, a GPS dongle would do the job. They're inexpensive.

Worst case: Set the PC clock manually by watching an analog clock on a cell phone, and clicking the PC clock button when the cell clock second hand passes 12.

Yes, I use a program called NetTime which works great as you specify the frequency of updating.  The original poster was referring to a circumstance where the computer is not connected to a network (internet).

Thanks Steven
I originally posted version A.  I'm now up to version K and learning more & more about Pixinsight.  This is a good one to practice with.

Good luck, looking forward to seeing your results.

>> Thanks Ray. Do I need to point it to a target while doing Plate Solve and Recal?

yes - and (my personal advice) it's better near the zenith. Avoid plate solve near the poles

Hi Tom,

I have a 294 pt model and had SGP slew to Veil Nebula but it missed by a few degrees, and I have a FSQ106 with a FL of 530mm, pretty wide.

I am disappointed.

Nick, the AP mount (at least my Mach 2) does not get the time from a
GPS. APCC initializes the mount with the computer time. So we would
need a GPS connected to the computer to set the computer time first.
Or set the computer to set its clock automatically from a network time server.

Recent versions of Windows do this automatically, or you can use a third-party application like Dimension 4 <http://thinkman.com/dimension4/>.

I use Dimension 4 on my observatory PC, and I've never had a problem with my 1200 mount not point accurately.

Q1: If after creating a model, if I configure HOME (I have AP1100 with AE), does it nullify the model?
No.

Q2: With a large APPM model, is the RA/DEC as entered in Sequence Generator Pro expected to be
centered?

Last night SGP did not center the target (I forgot to check slew & center which platesolves) and it was off by a
few degrees
Try clicking the "Plate Solve and Recal" button in APPM. This should resync your mount to the model.

Hi Nick,

APCC feature request - Get time from mount.
You can see the mount's time on APCC's Site tab. Is this what you are requesting?

APCC feature request - Get time from mount.

We can get latitude and longitude from the mount, time is useful too. This is for people who run PCs that are
not connected to a network but are connected to a mount that has been initialised with GPS accuracy.

If the mount and the PC have different times then problems like this https://ap-
gto.groups.io/g/main/topic/80392492#76045 can occur. I have verified that the problem does not occur if the
times are the same.

Something is off.
I just finished my model tonight, and I do not have encoders.
I skewed all over the sky using Voyager and the worse case deviation from perfect was 3 arc seconds.
Yes 3! 


Re: APCC feature request - Get time from mount

This would be interesting, as would the ability to set the computer time from a GPS connected to APCC.

I think that the problem is that you need admin rights to set the computer time.

Re: semi-OT: deterring critters in the obsy

Steven Panish
 

I use 1/4" hardware cloth and also finer mesh where the hardware cloth is impractical.  It seals my house sills and trim against the foundation.  My observatory (on posts) has mesh covering the bottom.  Mice have never gotten into the interior of either structure.  The observatory has board and batten siding over zip-system sheathing, and they have twice somehow made it into the space between the sheathing and the siding.  When they do that I set traps underneath the structure and get them.  And then there are the voles....but they don't come into structures, luckily.

Yup.  I agree with everything you said.  The super thin copper “Mouse-Mesh” is the only way I’ve found to keep them out of things.  And then I set electronic mouse traps – the ones that zap at a zillion volts.

 

And yes, I’ve found two mice in my electronic traps.  The second one climbed over the rotting dead body of the first – only to get zapped also.

Myth.  Mice really don't care about perfumy odors, or any other as far as I can tell.  They also don't mind living in close proximity to rotting fellow dead mice.  I have a blueberry farm and with massive quantity of fruit comes lots of rodents.   Wire mesh is about all that deters them.  There are some good traps available as well.  If you poison them you will also be poisoning critters that eat the dying mice, and they have a knack for finding a place to crawl into while dying that produces maximum odor if they have gotten inside anything.

I shot Pickering's Triangle through narrowband filters with the intent of producing a Hubble palette (SHO) image. However, the SII signal was largely superimposed on the Ha and didn't add anything useful, so I left out the SII and made a bicolor image with the other two filters. Here's the link:
