Thanks Howard 


Re: JPL Horizon wont launch in APCC

Good Morning, Peter.  Also, make sure you have the current APCC/Horizons installed.  JPL changed their format a while back and Ray had to update the Horizons program to accommodate.

Steve,

 

Thanks for the follow-up on the ConeSharp adjustment method(s).   I just thought I was blindly missing the features that dove plates were supposed to have or could be adjusted to have.

 

Cheers,

Greg

Your computer/antivirus is probably blocking Horizons from accessing the internet, but if you can get to the website manually via Chrome, that will work too. Just follow the directions in the help file.

Website won’t respond correctly. I am using windows 10 on a eagle computer. Using chrome as browser which
works when I just use browser. But won’t when I use horizon thru apcc.

Hi Peter

are you saying the website is not responding correctly?

i just checked direct and through APCC and horizons comes up for me and seems to work fine

I use chrome/windows 11

Re: Mount will not power on or boot up

There is no internal fuse. The internal board may have come loose and pulled out of its socket. This can happen if the CP4 was dropped upside down.

Remove the top white cover by removing 4 screws (be careful to not pull out the antenna wire from the PC board). You will see the upper board that has the microprocessor on it. Push down on it to seat it fully in its connector. There are 2 standoffs that the board snaps into. Make sure it sits fully on those standoffs. Plug the 12 volt power into the CP4 and check to see if the LED lights. If it does, you should be able to communicate with the keypad. Replace the cover if everything checks out.

Call the office tomorrow if this does not work. You can request a return authorization and we can fix it pretty quickly and get you back in business.

1100GTO will not power on.  Main battery shows 12.76V and backup battery shows 12.5V.  Keypad simply says "Astro-Physics Ver: 4.19.3" and will not proceed beyond that point.  Reads drawing 0 amps and LED light on GTOCP4 is not lit.   No change with Regulated Power supply.  Is there an internal fuse or a reset procedure?

Roland,

 

Thank you.  I am looking at trying out APCC Horizons to see if that will help out with better lunar tracking.

 

Yours truly,

The Lunar rate is an average rate in RA only. You would need a custom rate for both axes to follow the Moon precisely.

Tonight, I was using a 16" RC at f/6.4 with a full frame sensor to watch the eclipse.  I also had a 91mm scope riding parallel to provide a wider FOV.  In the 16", I could see about 95% of the lunar disk.  But I constantly had to move the scope in the North direction as the Moon kept dropping down in the FOV.  The mount is permanently mounted in my observatory and polar aligned.  I verified this with my PoleMaster the other night.  I know the Moon's motion varies from day to day, but I would have assumed that the lunar rate would take that into account.  Do I have to guide on a small lunar crater to keep the Moon centered in the FOV?

Re: Testing PC connection

Howard Hedlund
 

No problem.  If you initialize the GTOCP4 by itself, set tracking to zero or you will get a motor stall.

Thanks Howard. I will look up that aspect of APCC PRO and try it out

Ray's *Horizons* program, which is a part of APCC, can give you very tight lunar tracking.

Konstantin,

 

Thank you.  The East-West tracking was pretty good while in lunar rate.  So I guess Lunar Rate was controlling RA pretty well.  The major drift was in the north-south axes, and that was probably due to the low altitude and atmospheric aberration.  When I started, the Moon was only 18 degrees up in the southeast, and by totality it about 30 degrees up.

 

Yours truly,

 

Jack

Lunar rate works only in RA. There is also the atmospheric aberration!

Re: AP1100 autoguiding

Steven Panish
 

Hi Greg,
Unfortunately it is rare  to find cone adjustment screws actually on plates or rings.  Vixen does it for some  premium refractors.  Generally you are going to have to drill and tap holes for the screws...somewhere.  Maybe in the rings.  You need them front and rear, and left and right.   And you may have to use shims where nothing else will work.    I use shims made from aluminum flashing against the tube of my FSQ106.  It's crude but works.  On SCTs I've put adjustment screws in the dovetail attached to the tube (actually the dovetail bar is attached to the rear cell casting and a similar casting in the front).  

However you do it, the program will help.  With AP components you likely won't be too far out.

Steve,

 

Thanks for the advice about ConeSharp – I was unfamiliar with it.  I looked up the instructions and it seems pretty straightforward.

 

However, I am curious how you are supposed to adjust out the error and bring the alignment star back in the center of view.   It says to only use the adjustment bolts at the front and the back of the dovetail.  Here is the quotation: ”Remember that you are only allowed to make corrections using the alignment adjusting bolts at the front/back of the dovetail.”

 

I am using a 130EDFGT on a Mach2 on which I’m using an AP DOVEDV10 saddle plate.  The 130 is using the rings  that I purchased with it and they are mounted on an SBD12 12in plate.  The screws for the rings fit in countersunk holes in the plate and have no adjustment.   So I’m at a loss to find the adjusting bolts.   (The Google hit from Cloudy Nights on the topic of ConeSharp proclaims “NO SHIMS.”)

 

Any insight about how you do this would be appreciated.

 

Cheers,

Greg
