Craig,

 

The greasing concept for the 1200 and 1600 are, for the most part, the same.    If you email me directly, I’ll send you the greasing instructions.  

 

Regards,

Karen,
Given the current delays and increased cost with International shipping, it would be weeks to months before I would get the grease kit here in New Zealand.  I did watch the video linked above and got the gist of how to do it.  Would AP recommend any difference in the procedure, or could you email out specific instructions for the 1600 mount (purchased about 6 years ago).  Like Mike, the OTA is off the mount and now is a convenient time to service it.

Hi Bill,

Did the beta not get promoted to the latest version?
No, it did not get promoted. There is an incompatibility between Eltima V10 and Windows 7, which required further changes. There were also additional changes to Horizons.

Here are the links to the release version of Pro and Standard:

https://www.apastrosoftware.com/apcc_download/APCC_Pro_Setup_1.9.3.1a.exe

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?

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:

A few questions:

1. How old is the model?

3. Did the issue always happen, or did it start a while after the model was created?

Also, if you are not using APCC 1.9, you should update. (You do not need a subscription to update to
the latest build. If your license is older, you may not get the new major features, but you will still get bug fixes
and minor feature improvements.)

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

Scott Cooke
 

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.
