TAC Visual / Advice needed for Pinnacles East
« Last post by jeffweiss9 on June 20, 2017, 07:50:32 PM »
D.A.R.C. is down for 2 weeks and I'd like to try the Pinnacles East (road closure on the West) for some imaging but I need advice on best observing location there.  Is that at the campground (where Clear Sky Chart is) or up 146 somewhere like the 'peak view point (sounds more likely).  Suggestions or info appreciated.
Thanks,
CS/Jeff

Equipment Discussions / Re: Help Upgrading Argo Navis firmware?
« Last post by wkf on June 19, 2017, 10:53:09 PM »
I've made some progress as I located my pn-ser-cbl.  However, the firmware fails to update:

I followed the directions in the ArgoLoad program.  I am able to confirm connection from my Mac to the Argo Navis using these steps:

screen /dev/tty.usbserial 38400
% sound


This causes the unit to beep so I know the connection from my Macintosh OS X Sierra to the unit is working fine.  The Argo Navis Serial1 Baud is 38400 and Startup is set to navis.

However, when I put Argo Navis into boot loader v1.0.2 and launch ArgoLoad, all is fine in the executable until I select the file for the firmware upgrade: navis_app301.sgz  Once the file is selected, it leaves a blank white area on the screen where the dialog once was and I get the spinning rainbow color wheel whenever mouse is over the now white area where choose file dialog was or over the ArgoLoad application window.  I rebuilt the ArgoLoad with xCode to use #define SERIAL_DEVICE "/dev/tty.usbserial" instead of default location.

Once the white area appears where the choose file dialog for the firmware file appears, nothing happens no matter how long I wait and I have to kill the locked up ArgoLoad application.  The Argo Navis LED screen never changes from Boot Loader v1.0.2.

Some questions:
  • Is ArgoLoad known to work with Mac OS X Sierra?
  • Is it known to work with Boot Loader v1.0.2 or do I need to update that somehow instead?
  • What else can I try to get the firmware updated?

Steve, will you be at GSSP?  Maybe we can find someone there to help us both upgrade our systems?

I didn't realize that my Servocat needed upgrading too.  I now see that Argo Navis v3.0.0 requires Servocat v7 or later, thanks for alerting me!  I wonder if upgrading to Servocat v7 requires Argo Navis v3.0?

I'm also interested in updating my AN firmware, as well as the Servocat firmware.  Has anyone performed this update?

Cor Caroli was cleanly resolved at 25x using my 80mm finder and even 13x split the pair.  Here's another approach -- what's the lowest magnification to resolve this gorgeous duo?

Does anyone have the capability to help me upgrade the firmware on my Argo Navis?  I'd like to upgrade from v2.0.0 to v3.0.1  I've got cables on order but don't have the RJ-11 to RS-232 piece of the hookup.  Would love to do this before GSSP.  :)

The exact cable I need is the: pn-ser-cbl Argo Navis Serial Cable.

Well thanks John for the reminder to post a correction here. Phooey, last time I'd checked the Pinnacles NP site, there was nothing about a road closure, so I was feeling all sanguine. Just did check back (unprompted I swear), and yep according to
https://www.nps.gov/pinn/index.htm
right on their front webpage, 146 will be closed 2100-0600 thru June. So stargazing is fine if you want to stay till 6 am.

You said 22 July. That's supposed to be just fine.

I'll head to the Peak this evening! Will be in the SW lot.

We've had a couple dark nights with good stars and a visible Milky Way here in Salinas. Time to head for the dark hills. Will be there well before sunset.

TAC Visual / Triple double with Cor Caroli
« Last post by mccarthymark on June 14, 2017, 12:56:46 PM »
While hunting faint and close pairs with my 12.5-inch last night, I realized there is a "triple double" which includes Cor Caroli!  They're not all physically bound to each other, but it was a nice scene all the same.

Cor Caroli = STF 1692 is the well beloved Alpha Canum Venaticorum and was the start of my star hop for the list of pairs I prepared for the session.  About half a degree to the west was STF 1688, a faint pair (9.24/11.06, 14.4", 343°), yellow A and orangish B, which I identified using 340x.  Next on the list was STF 1702, which was about half a degree to the east of Cor Caroli.  It was a wide orange-yellow pair, 8.72/9.41, 36.1", 82°.

It struck me it might be possible to see all three in the same FOV, so I went down to 71x and 1.1° and yes, I could just squeeze all three in the view, the two fainter Struves just within the field stop on either side of the showpiece in the center.  It helped to have already seen STF 1688, since it was the faintest pair to pick out.

It's these little scenes which give me great satisfaction while observing.  Hope you have something new to look for when observing this old favorite.
