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

W Hilmo
 

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.

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.

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.

Two APPM Questions

Shailesh Trivedi
 

Q1: If after creating a model, if I configure HOME (I have AP1100 with AE), does it nullify the model?

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

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:

Thanks, all.  Very helpful.  I believe my outdoor outlet is already GFCI protected but will perform a test to confirm before plugging anything in.

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.

Reflection in image

Robert Chozick <rchozick@...>
 

What would cause the refections in this image?  It has been suggested to be a reflection in one of the t-thread  or 2 inch extensions.  I also place a 2 inch UV/IR filter at the end of the AP CCDT67 tele compressor.  The order is ZWO 2600 color camera + t-thread extensions  + t-thread to 2 inch adapter + 2 inch extensions + CCDT67 + 2 inch Baader UV/IR filter.   I space it to be a .67 reduction factor.  Any help diagnosing this would be appreciated.

Shipping box and foam for Mach1

Patrick Spencer
 

Does anyone know if AP still sells boxes and foam that can be used to ship a Mach 1? I know there was a recent discussion about buying boxes for the 1100GTO, but I'm wondering about the Mach1, since it's no longer in production?

Thanks,

Yes if you do that type of work on your scope mounted PC, I'd look at i5 or better NUC computers. Running software for controlling normal DSO imaging these things are perfect low cost and highly effective little boxes.

Re: AP1100AE Unexpected park?

Ray Gralak wrote:

From the log file, I eliminated all possibilities except for manual double-clicking of the park-status on APCC's status bar, which matches the expected
command sequence from that action (two Q commands and the KA).

So, is it possible you had double-clicked the park field in the status bar?
Well, there's some line from Sherlock Holms about what remains after you eliminate all other possibilities being true, so it must be.

First, I didn’t even realize the bottom bar was active, I thought it was status only, so I learned something. At that time I was on a Android phone on an RDP client, where I drag fingers around to zoom into various parts of the screen. It's certainly possible I touched that bar, it's even possible the result was a click or double click though that usually takes more effort as you drag a pointer onto the thing you want to click, then tap it. But it's awkward working on a tiny screen and who knows. And I was half asleep.

I think I also figured out the half empty ASCOM logs, though not entirely. I keep the ASCOM driver set to default to PARK 2, since that's where a safety park will send it from NINA if it detects rain (or at end of sequence), aiming the OTA sideways not up. I keep the APCC set to Park 3, as that's where I load and unload. That means when I manually park, I do it from APCC, which I guess is rather invisible to ASCOM?

So my GUESS is that ASCOM figured out at 10pm that I parked, stopped logging. After 6am NINA parked it at the end of a sequence through ASCOM. I then unparked it in NINA to run another sequence for flats, and it started logging. What I don't quite understand is the 10pm stop was definitely from clicking on a slew-stop (I think) or emergency stop (possibly) in APCC when I realized I needed to go balance things. So not quite sure how ASCOM figured out it was parked.

Anyway, I think the logging being off was from me jumping the line, as it were, and using APCC directly so ASCOM got confused and left logging off even though it was running for hours live and unparked.

I do rather like having two different default park positions, at first that seemed redundant, but it's quite handy.

Thanks for playing Sherlock for my mystery. I learned several things... all this actually started by not remembering to turn off a questionable model, so I got to see how that affected guiding as well. My guess is that smaller model didn’t even cover the section of sky I was in by 5am -- I haven't had a chance to do the whole, entire, cloud free sky since I got the mount. Dry season is coming, I hope....

Thanks again,

Linwood
