Re: APCC Pro model details #APCC

It would be really nice if the documentation stated what "good" and "bad" values were based on your mount and scope, and more importantly,  what, if anything should be done to improve the numbers.
A simple example: running a T-Point model tells you your polar alignment error and says things like "Turn the right knob 3 ticks" or "your error is good enough".  However, for the other numbers it's no better than APPM in that it also leaves you guessing regarding what, if anything should be done.

Hi Konstantin,

The symptoms have nothing to do with P02-08.  They are related to differences in silicon.

We received a different version of silicon than we specified a while back.  Unfortunately, by the time we discovered this, a few units had snuck out the door.  P02-08 is what we happened to be shipping at the time.  All versions subsequent to P02-08 accommodate multiple versions of silicon.  The silicon differences only affect field updates of firmware, which is why they test fine in the factory and in the observatory.

Regards,
Mike

Hi Alex,

We'll contact you privately.

Anyone else with symptoms identical to Alex's, please contact us directly.  It requires a little TLC to get past P02-08 in a very small subset of control boxes.

Try downloading .pt1 file first and then .pt2 file.

Unable to update firmware of CP4

Alex
 


I have an 1100 with a GTOCP4 running the VCP4-P02-08 version of the firmware.  I just attempted to update it to the latest VCPX-P02-11.  I freshly powered cycled the CP4 after removing the USB connection to the computer.  I have no problem connecting to the embedded web page of the CP4 via the ethernet connection.  I go the the Load New Software page, select the VCPx-P02-11.pt2 file and the page indicates the file is ok.  I hit the program button, the download is ok, it prepares the file the says it's "Running New Program".  I then choose the VCPx-P02-11.pt1 file and hit the program button, and the page updates with "Resumed Operation".  When I return to main, the displayed version is still VCP4-P02-08.  I've done this several times now.  I never see an error, but the version doesn't update.  Any suggestions as to what I may try next?

Alex


Re: initialization of Mach2

With the Mach2 mount that is not necessary. You can start the mount from any position, even pointing straight down into the ground.

With the other mounts that we make, the 1100/1600 you will need to start from a known position.

Thanks Karen and Roberto.  I always look forward to this time of year when I can try and add a few more of the dark nebula that are low in the south to my collection.

This is the first Milky Way shot for me this year and a chance to check off some more dark nebula on my to-do list.

This image is centered on Barnard 63 and includes Barnard 62 as well as a good number of dark nebula from Beverly Lynds' Dark Nebula catalog:

https://www.astrobin.com/full/7bes64/0/

Although my imaging location is relatively far south here in Southern California, at -20 degrees this field is pretty far down in the weeds so to speak.  None of the small field stars in the subs were sharp.  The seeing was pretty bad.

Imaged with the Mach2

- 73 x 180 seconds, unguided

Re: initialization of Mach2

Roland Christen
 

There is no mechanical initialization required. No unparking from any parks required - the mount is ready to roll the moment you apply power. Once you connect the mount to your planetarium app using the ASCOM driver, all you need to do is slew to a star or deep sky object. The mount does the rest.

Re: initialization of Mach2

That is correct. The Mach2 always know where it's at. Even with clutches loose.

The only need for homing would be if you made a bad sync/recal at some point (but if you platesolve that's not likely to happen). You can then home it (which indeed sends the mount to park 3) via the AE tab in APCC or with the Keypad and you are back in business. Simple as that.

I agree.  I'll wait to hear from more knowledgeable persons but I have never unparked my Mach2 from any park position like I used to do with may AP900.  I just set up the mount and initialize it in whatever position it happens to be in.

My setup routine is:
1. initialize the mount with APCC to one of my pre-set locations. 
2. Do an initial alignment with the RAPAS. 
3. Do another alignment with SharpCap. 
4. Connect to TheSky and use TheSky to slew to a bright star. The star is always on the chip and pretty close to center.
5. Center the star with the crossharis in my image capture program and perform a Star Sync with TheSky.

That's it.  A lot simpler that with my AP900 because the mount already has a good idea of where it is pointing.  I just have to refine things a little after the polar alignment.

When I am done with the mount, I just turn it off.  With the AP900 on multi night trips I would park the 900 in Park3 so the mount would know where it is on the next night.  I don't have to do that with the Mach2.  I just turn it off.  I can loosen the clutches and re-balance when the mount is powered down and the Mach2 is dead-on when I start it back up.

Re: initialization of Mach2

M Hambrick
 

You should definitely start out the first time from Park 3 as Brian and Jeff have noted, but after you do the first-time initialization in Park 3 you may want to consider parking and unparking the mount from Park 2. If you have a portable setup where you attach the scope every time, the Park 2 position makes is a little easier to attach and remove the scope.

Beautiful Dean. Great catch from your location.

Re: initialization of Mach2

 

yes, you set it at that position and then unpark from park 3
