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:

Finally there’s using three different AC -> DC adapters.  I’m a proponent of grounding all of those together so there are no floating voltages against their ground, because if there are, these tend to flow over other connections not intended to carry significant current, notably USB cables. 

  In general, it's not necessary to do more than connect your AC adapters into outlets which are closely coupled, as on a power strip. All AC adapters with two-prong plugs, and most with three prong plugs provide isolation between the DC output and the contacts in an AC outlet. If you use a power strip near the telescope and plug all of the adapters into it, you should have no problems at all. Even if you run an Ethernet cable back into your house, there's little risk of problems because the connections are transformer coupled on each end (meaning that there's no direct path for current to flow from the Ethernet cable to the electronics on either end). USB is a little different since it relies upon current flow at both ends of the cable, so you may not want to run that between your office and telescope, however connections between cameras, filter wheels, computers, etc., at the telescope should not present any issues.

  The recommendation to ensure that you have GFCI protection for any line voltage used outdoors is a good one. An inexpensive ground fault detector is a worthwhile tool for any homeowner. These provide a button that allows a small current to pass between line voltage and ground, which will trip a GFCI if there is one in the circuit. If you plug the tester into an outdoor outlet and the lights on the tester don't go off as soon as the test button is pressed, either the existing GFCI has failed or there wasn't one to begin with. That's not a good thing.

  In many houses, the GFCI protecting outdoor outlets is installed in one of the bathrooms. If you have a GFCI in a bathroom, you can plug a lamp into an outdoor outlet then press the test button the GFCI. If the lamp goes off, the outdoor circuit is properly protected.
