Horizons 1.9.2.errors loading emphemeris

Bill Conrad
 

I know there was a beta of Horizons that corrected for the new JPL format.
I'm using Horizons 1.9.2.3 and still need to edit the format to correct the "Azi___(a-app)__Elev" to "Azi_(a-appr)_Elev" header.
Did the beta not get promoted to the latest version?

Thanks

Re: Unusual APCC and Mach 2 behavior after the meridian #APCC #Mach2GTO

Ray Gralak
 

Hi Marcelo,

I only noticed the effect a week or two ago and the only significant change has been the ambient temperature.
It's summer here and it's around 19°C at night.
Large changes in temperature not only affect refraction but the rigidity of the equipment, which will "bend" slightly more with increased temperature. This can change some of the pointing term values.

The mount is semi-permanently located in my backyard on a portable pier, the black one that AP sells. And it
hasn't moved in over a year.
In a portable pier setup, polar alignment can shift as moisture in the ground changes.

I suggest you check/tighten the scope's rings, mounting plate, camera connections, etc. Also, eliminate any drooping cables, then create a new 200+ point model to see if that solves the problem.

(I will update APCC. I'm actually waiting for the latest version to come out of beta to test it, I'm interested in
the new options on the meridian limits).
Here is a link to the latest version of APCC with updated help. This is a release build, the only caveat being Dale Ghent may not have released an updated NINA build yet to support the latest REST API changes in APPM:

Also, if you are not using APCC 1.9, you should update. (You do not need a subscription to update to

The modeling is from a few months ago, specifically October 25, 2021.

The modeling is 205 points.

Re: 1600GTO Encoder LED Color #Absolute_Encoders

Bill Long
 

Mine are green on Dec, blue on RA. The OCD in me tried to get the Dec blue and I can, but as soon as I tighten the screw it switches back to green. 🤣 Oddly enough it needs to move outward a tiny amount to turn blue.

Not a big deal since it works perfectly, but I felt like the read head was teasing me. 😭

If you loosen the LED cover screws and slide the cover around carefully, you can get it to go from yellow to blue. When it's blue, tighten the screws and you are good to go. This does not change the encoder alignment, it simply adjusts the readhead clearance dimension until it falls into the "perfect" position. Any colors from green to blue are considered perfect and will allow the CP4 to read the encoder scribe marks. Even yellow works, but is considered marginal spacing. Red means that the readhead is not picking up the encoder signals.

Hello,

I recently bought a used 1600 with AE from the original owner.  It is raining here in California, so I have not been able to use it to image yet, but have been testing it in the garage.  Using APCC-Pro, I hooked it up and played with it.  I don't get any errors, and the AE tab is available and the encoders are enabled.  I noticed that there is a Green LED showing on the RA AE cover, but the DEC AE cover led is orange.  Is this normal, or is something set up incorrectly?

Thanks Roland.  I tested it across the full range of motion.  The RA stays green the whole time.  I will try to adjust the DEC as it is always orange with a couple of spots turning red.

Re: Insurance for AP Mounts

I have a rider on my homeowners policy of what's known as personal inland marine floater policy.  It covers all my listed gear at $1.60/$100.  It covers breakage, theft, damage from water, basically all losses including something called mysterious disappearance which means it's covered even if I just lose it.  I had to photograph everything to verify ownership and document value either through retail prices or used ads for items no longer available new.  They will cover each item for the amount documented.
Thanks,
Scott

For my amateur radio hobby, I pay $108 for an insurance policy that
covers all my ham gear, about $7,800 worth, for one year. The premium
rate of $1.40/$100 has not changed for three years. The policy covers
equipment (per the website) "...on a replacement cost basis. Coverage is
all risk with few exclusions."

These policies are offered to members of the American Radio Relay League
(ARRL), and underwritten by Risk Strategies Company in Chicago.

I wonder if any amateur astronomy association has or might be willing to
offer similar policies.

Oh, and the usual insurance games such as loss coverage not applying because of specific causes like flooding (either natural or from things like a backed-up sewer/septic) and such will be part of the game.

The case of floods causes by a public sewer backup can get interesting depending on where you live. Sometimes your sewer authority will cover cleanup and deprecated value of what was lost, but if you take that payout, you can’t also file an insurance claim on the list items, and vice versa. It’s literally a shitty situation to be in because you’ve got a basement full of actual crap and you have to make a sort of snap decision on who will give you the better payout so you can begin rebuilding.

I put my AP1100 (and everything in my observatory) on a separate rider that costs roughly $600/yr (State Farm). Just needed to itemize and declare the paid value for it all, took a bit of time to do and was an eye opener on how much I have spent over the last couple decades!

Re: 1600GTO Encoder LED Color #Absolute_Encoders

W Hilmo
 

The read heads for the encoders are standard Renishaw parts (packaged by Astro-Physics to fit your mount).  You can go to the Renishaw web site and download the documentation for them.  I did that at one point, but it was many years ago, so I don't have a direct link handy.

The color coding on the read heads is an indication of signal strength.  There are 4 possible colors.  In order of strongest to weakest signal, they are blue, green, orange and red.  If you run the mount's axes all the way around, you'll probably see that the color changes periodically as the read head passes over different parts of the encoder wheel.

I installed the encoders on my mount myself.  After the initial install, I got lots of orange, and a few red, spots on each encoder.  I was able to make some simple adjustments on each read head and got all green and blue indications.  I've not had to adjust them since, even though I transport this mount fairly often.

If you get an orange status for lots of positions of the axis, it might be worth contacting George at Astro-Physics for assistance with adjusting them.  It is quite easy (it took me about 10 minutes to adjust both read heads when I installed mine).  If you get mostly green and blue indications when you run the axis all the way around, with just a couple blips of orange, it might not be worth playing with it.  The read heads will still work just fine with an orange indicator.  If you get red indications when you run the mount all the way around, that would be something that should be adjusted.

Re: Insurance for AP Mounts

My home-owners does not have a limit for non-scheduled items, but it is only going to cover things like theft and fire. Having it destroyed by a roaming grizzly bear at night... maybe. Having it destroyed because I left it outside with the sprinklers on, definitely not (ok, so that might not destroy it, but you get the idea - a mea culpa of some sort). 

Your insurer will happily add it on a rider, I suspect, but like expensive camera gear (which I've thought about for years), getting it insured for the most likely things that will cause a loss (in my case user error of some sort) is hard, or expensive, or both.  So I just self-insure.

So I'm curious if people have better solutions.
