Re: Power supply through the Mach2 mount to Pegasus Astro UPBv2

Michael Kelly
 

I’ll gladly make one for you for just a few bucks and for whatever the shipping is. I’ve got a few extra XT60’s and a Powerpole crimping set up.  Let me know how long you want it.  14ga is plenty HD enough. I run a PW (with a very large primary mirror heater and secondary mirror heater), a dew heater on the guidescope, camera cooler, OTA cooling fans, etc all thru an UPB.  The Powerwerks power supply has never showed over 6A current draw even while slewing a maxxed out Mach 1. 

Let me know if you’re interested. 

Best,

Hi,

if you by the Pegasus powerbox, there is a cable comming with it, that has the XT60 connector on one side. The other is free. So you can crip your power pole to the other side.

Hi folks I have a few questions about power supply via the Mach2

I am thinking of getting a Pegasus Astro Ultimate Powebox (UPBv2), but wanting to attach it via my Mach2's internal cabling as opposed to a dangling cable. Essentially I am trying one of the example setups mentioned in the Mach2 manual page 23. What will get attached to the UPBv2 is a typical setup of cameras/filter wheel/maybe focuser/maybe dew heater.

  1. So this means that the UPBv2's PSU (12v/10A) with XT60 connector is not useful on its own. If anyone here uses the same setup, did you just chop off the XT60 connector from that PSU and install an Anderson Powerpole connector instead to re-utilize that PSU for powering the Mach2 internal? Though I think I would just prefer to get a new PSU and save this one if I ever want to re-sell the UPBv2.
  2. If not that PSU, what PSU do folks use? Any recommendations? I see AP lists this one from Powerwerx. But can I just get away with something simpler like this 12V 20.8A one instead since I don't think I would need a variable PSU? Are there any other readily available PSUs with Anderson Powerpoles that can supply 12v/10-20A which is the recommended input for UPBv2. So that I am not attaching those connectors myself.
  3. What is the wire gauge / ampere rating for the internal cabling in the Mach2? I think I read in another thread it can easily do 15amps, but did not see any upper limits or I missed it.
  4. Likewise what wire gauge should I use for this setup? The Mach2 manual recommends 14 gauge on page 21, but instead recommends 16-18 gauge on page 23 for this setup. I was going to go with 16 AWG since it has higher amp rating but in another thread someone mentioned that accessories might prefer 18 AWG. The distance of the UPBv2 from the dec axis will obviously be very small, so maybe 18AWG will suffice too since it can do 15-20 amps max in short distances. Though this will obviously be limited by the internal cabling of the Mach2 as well as the cabling of the PSU itself to the RA axis input.
  5. Since I will need a custom Anderson Powerpole to XT60 wire for connecting the UPBv2 from the dec axis, where does one get such a custom wire? Powerwerx doesn't seem to have this connector and the only place I could find it was from some random amazon seller.
Thanks!

You can source XT60 to Powerpole pigtails for cheap. That way you can leave the original power cable that comes with the UPB v2 alone.

Furthermore,

For short runs of wire above the mount, at the scope, it is not important to have heavy gauge wire. A short piece of lighter gage can carry as much current as a long piece of heavy gage.
For wire leading up to the mount, from a power supply, it is best to use as heavy a gage as possible, since that is where the voltage drop takes place from supply to mount. You want to minimize that drop. So using 14 gage is probably the best on that end.

Re: New AP1600 slew noise

Yasushi Fukunaga
 

Hi Luke,
I noticed my 3-year old AP1600 had a noise issue a few months ago. It happened in both RA and Dec but in random fashion.
Consulting with George@AP, I got the advice and conducted the slew speed set to 600x and the re-greasing for RA and Dec gearboxes, which perfectly resolved the issue.


> In cold weather the mount should be slewed at 600x.    You made need to do an adjustment of the Backstop (while in Park 3 and the power off).

New AP1600 slew noise

Luke Dodd
 

We have finally had some clear skies downunder to use my new AP1600 delivered a few months ago. I have noticed some slews are very noisy, particularly in the RA, but also Dec gearboxes. Noise is high pitch and varies in frequency, almost sounds like the motor is about to stall. Other Slews are very smooth and the noise very consistent. Mount is well balance and scope weighs 30kg, slew speed 600X. Temp is16 degrees Celcius. Is this normal? Thanks

However I'm unable to download the file from the AP website: it keeps asking to sign in with user and password.
I did register on the AP website, but that user and password is not what you need to download the keypad update file.

Is there any obvious solution (like mount or keypad serial#) or should I contact AP to ask for a password?

Subject: [ap-gto] New on this list : Keypad update question

Hello all,

I have recently acquired an AP1200GTOCP3 with GTO1 Keypad, but I would like to update the software version from v4.15 to v4.19.3 (as recommended).
However I'm unable to download the file from the AP website: it keeps asking to sign in with user and password.
I did register on the AP website, but that user and password is not what you need to download the keypad update file.

Is there any obvious solution (like mount or keypad serial#) or should I contact AP to ask for a password?

Best Regards,
Tom Alderweireldt

Re: Having fun with old equipment

It was an all-sky model, 10 degree Dec spacing, 10 degrees RA spacing, 4.5 hours either side of the meridian.
It's important to have no mirror shift or flex in the scope - my 17" has an ultra-light weight quartz mirror that does not move (hardly affected by gravity). The secondary mirror is also light weight quartz and the secondary holder and spider vanes are very rigid.

The mount is on a heavy ATS pier, sitting on a 6 ft deep concrete block. It is not perfectly polar aligned and there is some natural drift consisting of atmospheric refraction and PA error. In the area I was shooting the drift ranged from 75  to 20 arc sec per hour as the object rose higher in the sky. With the model activated the drift was reduced to around 4 arc sec per hour, so a 5 minute exposure would produce about 1/3 arc sec drift. That's good enough for a night where the seeing was between 1.5 and 2 arc sec FWHM.

When we designed this 17" scope we wanted to make sure that it would not be a source of error. We wanted a setup to allow us to measure the mount errors without having them influenced by a floppy scope system. People sometimes forget that the scope can also be a source of significant pointing errors that are random in nature and can prevent precise pointing/tracking.

Quick question about your model Roland.  Was that an all sky 190 point model, or did you do a Dec-Arc model around the Dec of your target?  Just wondering what you settings were for the model.  I am still trying to get a handle on the Dec-arc vs just Enable Tracking Correction.  I have not been able to get consistent unguided results like you describe with my AP1600AE, and am wondering if there are some guidelines on the settings needed for particular focal lengths.  I know that a while back that George had a post with some guidelines, but I couldn't find it.

BTW - Nice image of M57.  You did a good job processing it to maintain the colors.

That’s exactly what you needed to do.  You’re on the list.

Great!  I have been wanting to upgrade my AP1100 since I got it.  I went to website and found the encoder upgrade page, then put my email into the Notify Me box.  Is that what I needed to do to get on the list?  Or is there something else?
