Re: Mach2GTO Anderson Powerpole passthrough current rating #Mach2GTO

Christopher Erickson
 

It is a straight-through run that is fully isolated from the mount frame, as it should be. It has no internal fusing. That wouldn't be a bad thing to add. My memory is a bit faded but IIRC, it is 14 ga wire and can handle up to 15 amps, although 10 amps is a more reasonable limit. Roland or George will correct me if I am wrong.

IMHO, putting anything besides 12-14 VDC on it is inviting problems. Too easy to mix up power supplies and devices and burn stuff up. I think it is better to just run the 12-14 VDC and then use regulators to step the voltage down (or up) from there after it has emerged out of the top of the mount.

Of course YMMV.

How much current can I draw through the Anderson Powerpole passthrough on the Mach2GTO?

Or alternatively, what is the AWG & length of the internal wiring, and are the Powerpole connectors 15, 30 or 45 amp rated?

Second, are those wires pure passthrough without any connection (even just ground) to the mount's internal wiring? For example, is there a technical reason that it can't be used for 5V? Or 24V? Or 12V A/C ?

Personally I don't consider AP's approach to meridian management to be a "gaping hole" or "desperate" and I don't consider setting the AP meridian delay value to be "tricking" the mount. It has been thoughtfully designed to operate exactly the way it operates. No "tricks" required.

I guess I need to be educated as to what GEM GOTO mounts and hand controllers are out there that I don't have any experience with that have a manual meridian flip button or menu command in their hand controllers (or ASCOM/INDI drivers.)

Possible bug in AE tab in APCC 1.8.8.11

Luca Marinelli
 

Hi Ray,

While I was troubleshooting the declination axis motor issue with my Mach2, I noticed something that looks like a bug in APCC Pro 1.8.8.11 on the AE tab. If I start the homing process by pressing the FIND HOME button, the CANCEL HOME button does not appear to work correctly. In my case, FIND HOME failed because the mount couldn't energize the dec motor properly. When I pressed the CANCEL HOME button and confirmed by clicking NO - CANCEL Find Home button (which, by the way is always hidden under the current axis position) nothing happened and the homing process continued. 

Let me know if the logs may be helpful. I believe they were saved and am happy to send them to you.

Thanks,

Luca

Re: Meridian Flip Feature Yet?

Ray Gralak
 

Ray Palmer says - Yes, I have seen that feature and I appreciate you are trying to assist me, I really do, but I've
said so many times in this thread, my reason for needing to pier flip has nothing to do with
the meridian's position.
The meridian's position doesn't change. It is the reference line across the sky from due North to due South.

Maybe you meant "meridian delay"?

Because AP mounts can
track so far across the meridian everyone seems to be think there is no possible other requirement for pier flipping.
The meridian is only 10 percent of the reasons why people need to pier flip. If anyone thinks that pier flipping is
only for the meridian, then I would invite them to visit my observatory and see what an astronomer does over a few
nights.
Let me ask you this -- what if you could eliminate the *need* for a pier-flip button?

Suppose you could define the areas of the sky where you want the mount to be "counterweight-up" (i.e., opposite of normal pier-side) so when you slew the mount in SkyX the mount would automatically choose your desired pier-side?

That's one of the things that "Meridian Limits" can do in APCC.

Pier-flipping the way you want to do it is comparatively crude. :-)

Thank you in advance.

Thanks again for your time gentlemen, and it is evident that many AP owners cannot have access to a simple pier
flip command like most other manufacturers offer (unless we spend more money on APCC).

Hey Ray - you may want to reread what I wrote.

I offered to create a simple script for you for free. :-)

Or, you could upgrade to the GTOCP4.

Hi Ray,

Ray Palmer says - Why do we even need to trick the mount at all, when so many other mount manufacturers offer
a simple pier flip command as stock standard functionality?
Let's use your "other manufacturer" pier flip button as an example:

1. Say the mount is at (RA_1, Dec_1) - whatever coordinates those happen to be.
2. You click the "Pier Flip" and the mount goes to (RA_1, Dec_1) on the other pier side.
3. Later, you want to slew to (RA_2, Dec_2), but on the other side of the pier.
4. You first click the "pier flip" button, and the mount slews to (RA_1, Dec_1) on the opposite side of the pier, but you are not done.
5. Now you still have to issue the slew to (RA_2, Dec_2).

Is that how the other manufacturer's pier flip works? Is that how you would like it to work?

Now for an AP mount, using the meridian delay will define the destination pier-side of a slew such that there would only be a single slew from (RA_1, Dec_1) to (RA_2, Dec_2) on the other side of the pier.

Mach2GTO Anderson Powerpole passthrough current rating #Mach2GTO

deonb
 

How much current can I draw through the Anderson Powerpole passthrough on the Mach2GTO?

Or alternatively, what is the AWG & length of the internal wiring, and are the Powerpole connectors 15, 30 or 45 amp rated?

Second, are those wires pure passthrough without any connection (even just ground) to the mount's internal wiring? For example, is there a technical reason that it can't be used for 5V? Or 24V? Or 12V A/C ?


Re: Precise polar alignment of the azimuth axis

Steven Panish
 

10 min. unguided at 2800mm FL is pretty darn good!  Before I used SharpCap's method, I tried various manual drift techniques and only occasionally got it that good.  (C11??)  Now I understand that refraction at different altitudes is an issue - perhaps that was why the PA was never sufficiently reliable for longer unguided exposures.  Additionally my permanent pier is 10" iron pipe and quite tall, so thermally induced dimensional changes are likely an issue.

But although I have not done a new PA since using ConeSharp a few months ago, I earlier found all the procedures to give different results.  Not 4 minutes though.  That's pretty big.  Even when using the SharpCap procedure, redoing it after the 90deg rotation yields a difference  of typically 1minute.  So I split the difference of the two positions and am off about .5min on both.  It is a very quick method, which makes me prefer it over drift. 

Periodically I run the PHD2 guiding assistant, which gives a measure of PA.  It seems very sensitive to sky location, and also varies widely over time, not necessarily settling reliably.  Odd.  After letting it chug along for about 15 minutes it told me the error was 2'.  Sigh.  And with the drift techniques, including semi-automated ones such as in PemPro and PHD2, I found too much interaction when alternating between the Alt and Az settings.  I'd get it perfect on one, do the other, and going back to the first it would be off and/or would never improve with iterations.  That might be better now that the orthogonality is much better.  

At any rate, I gave up on unguided, it's too difficult for a relative newbie like me running at C11 and C9.25 focal lengths.  And I'm doing a lot of 20 min exposures on Sh2 objects.  PHD2 Guiding makes it easy, so I'm just sticking with that until there is some reason not to.  Now my gripe is that I can't get rid of the field curvature with the reducer/correctors.  Well, it's all a learning experience!

I'm sure either method is fine, especially if a little modeling is thrown in afterwards.  Just curious at trying a few different techniques more than anything else.  And I

It's relevant because if a telescope mount has a physical stop, the telescope may never physically get into a position where a pier collision can easily happen.

It is because A-P mounts don't have such a stop that pier collisions have more potential to happen. However, the lack of a physical stop offers the potential for a telescope to never need to be flipped throughout the night.

BTW, APCC has a meridian limits explorer tool to map out the slew limits at every declination and pier side. Once mapped out, APCC automatically allows pier flips within the meridian limits. Note that the concept of "meridian limits" is not the same as the mount's "meridian delay".

A pier flip in any mount results in multiple operations. In the case of an AP mount, the meridian delay is just one of the two commands needed to do a pier flip:

1. Set meridian delay.
2. Slew to current RA/Dec.

Setting the meridian delay sets the destination pier side.

Can the keypad be programmed to do that: yes. Can software be programmed to do that: yes.

APCC has a button to do a pier flip, but a simple script can be made to perform the pier flip without APCC. The script could be placed on the desktop and double-clicked when needed. I can't help you with the AP keypad operations, but I can create a (free) script for you that will flip the mount if you are interested?

In regard to that high tracking rate that you saw, I looked for that also, but couldn't find it. Do you have a menu
path to view that high tracking rate or
does it go away when the pointing/tracking options are deselected? Was wondering if that's something to look at
when modeling (later on) Thanks!
