Not sure whether or not I should post the resolution back here, but Roland was able to help me out, and it works great now without any oscillation.


Re: Meridian Flip Feature Yet?

ray.palmer@...
 

Hi Roberto,

I don't think that is what Rolando was referring to. That is a work around that tries to trick the mount into thinking it has hit the meridian. Your settings also may cause the mount to forget its location if the mount is not set back to 0W before powering off. I am looking for the one touch solution, where you hit a button and it flips (like a ton of other mounts do). AP's engineering is the best across the industry in IMHO, but it desperately needs a meridian flip feature. Playing with the settings to trick the mount to flipping is not a meridian flip feature. Note that I don't need a meridian flip because of the meridian's position. Note that the instructions make no reference to a "meridian flip" anywhere when searching for that search term, all they have is "meridian delay" (This is not a meridian flip feature).

Read the manual: https://www.astro-physics.info/tech_support/mounts/keypad/keypad-manual.pdf 
Page 59 has specific instructions for the Meridian Delay feature.

Mount RA/DEC slew math

deonb
 
Edited

I'm trying to correct my pier's N/S and E/W positions in my dome, so I stuck a camera in the middle of my scope's lens cap and ran a tape marker down the length of the dome shutter. I'm then trying to align one axis at a time.

I thought that if I slew from Alt:0 Az:90 to Alt:0, Az:270, the mount will only slew DEC without moving RA. So if the dome alignment is correct, I should be able to move the lock the RA axis and move the DEC axis manually bit by bit, mark a path on the dome (waiting for the dome to re-slew after each scope movement), then after Meridian flip follow that path down again and the up-and-down path markers should be in alignment. 

That's the theory... In practice what happens is that the RA axis also moves during this slew. Not a lot, but enough to make my doubt my hypothesis. I obviously can't move 2 axis's by hand.

Why is that? Isn't Alt:0 Az:90 and Alt:0, Az:270 on the same RA plane for every Lat?


Re: Meridian Flip Feature Yet?

ray.palmer@...
 

Hi Rolando, 

When I press the +- button, I get a menu that controls guiding speed and slewing speed, but pressing 9 does nothing. However when I press the bottom right corner button (RA / DEC / Rev), I do get a message on the screen that says 0W. Would that be the Meridian flip feature?

How do I disable (make it not-on top) the APCC always-on-top main window?

I figured it out for the AP ASCOM driver, but can't find that setting in APCC.

remove the top Dec cover
Remove the top cover of the DEC motor box, not the Dec axis top. It's the black anodized cover held on with 4 small screws.

Loosen all 4 clutch knobs. Move the Dec axis manually from one stop to the other. See if you can feel anything that prevents the axis from moving easily.

Then try moving the mount via the buttons at 1200x in Dec with clutches still loose. The motor should turn easily.
If it does not, remove the top Dec cover and look inside where the motor and belt reduction is. Can you turn the motor with the buttons now?

Thanks a lot for the quick reply, Roland. I am pretty sure I mounted the dovetail with the arrow pointing forward. The USB and power port are in the back of the scope, not on the side. See the attached picture.

Also, both N and S movements result in motor stalls, not just in one direction.

Thanks again,

Luca

It sounds like you are hitting the internal hard limit. You probably have the scope mounted at 90 degrees from the arrow on the top of the Dec mounting plate. Remove your scope and dovetail and look at the mounting plate. You will se a long arrow. This is the direction that your scope must point. You cannot mount it at 90 degrees or you simply run out of Dec motion when pointing south and the axis will hit the hard stop and the motors will stall with yellow light coming on.

Can you post a picture showing the scope pointing at the north pole?

Today I replaced the Mach1 in the observatory with the new Mach2 I received a few days ago. I have a Tak FSQ106 mounted on the Mach2 and it balanced without any problems. I tested a slew and everything worked fine. I then started to set up the Meridian limit in APCC Pro and after sending the scope to the Southern horizon (-15 degrees DEC) I started experiencing motor stalls. The mount makes a whirring/grinding noise when trying to slew in DEC and APCC communication window shows motor stall condition. The light on the CP5 turns amber. I measured the voltage out of the power supply and it is correct (24.94V). I also replaced the power supply with the power supply i used with the Mach1 and the same thing happened. To test the motor cable, I swapped DEC and RA cables and the fault was still on the DEC axis. I removed the telescope and tried slewing the empty mount in DEC, to no avail (motor stalls). 

APCC Pro version: 1.8.8.11

Is there anything obvious I am missing?

Re: Initial GoTo In APCC Pro Cause Nose or Tail Dive

John,

I see you have pointing correction enabled, and the tracking rate is extremely high, meaning you probably have a bad model.

So, try turning off tracking-rate and pointing correction on APCC's Pointing Model tab.

Aloha Ray,

I just sent you the screen shots via email.

Once I slew more than 10 degrees (in either direction), stop the slew, the DEC reads 00 00 00. While slewing and
holding down the left
mouse button, I can see the DEC coordinates actually slewing/changing. But after stopping the slew, the DEC

Kind of strange...

After pressing the 'find home' button, the DEC displays the coordinates correctly (after the slew stops) and like what

Hope the screen shots help, thanks!
