Previous iterations of the Ekos PAA would warn if you started within 60 degrees of the meridian, headed that way. E.g. if you were pointed at azimuth 160 and had "West" and "30 degrees" selected, a dialog would pop up, warning that the alignment might not be valid.

I happened to violate this "rule" last night by a few degrees, and no complaint. And a really good alignment, too!

So can I rely on this now? The field of view from my yard is quite restricted, which is why I'm aligning pointed south in the first place. If I can count on straddling the meridian with the three exposures, I'll be able to routinely use 30 degrees and so can count on more precise initial alignments.

If so...thanks folks! I just updated last night and the PAA worked like a dream, just chugging through with nary a hiccup. Well, OK, when I tried to wedge a 60-degree arc from just west of the meridian, it wasn't wild about plate solving the image of my neighbor's garage. I can be patient about including their garage in the catalogs, I guess.

The first time I got a successful run I did not see the updated polar alignment figures during the "refresh" cycle; the second time, the figures appeared, which was helpful.

Sadly, this did not work for me. Thanks though!

Thanks Fred, I'll dig the CEM70 out of the garage and give it a look tomorrow!

This is why I love this software. It just keeps on getting incredibly better. Thanks Hy!

Happened back upon this thread and felt compelled to clear up a point: It's not having the celestial pole in view that's an issue with PAA and long-focal-length optics, it's the alignment triangle. If you weren't pretty close to start with -- always an issue with us itinerant imagers, not so much with those who have the luxury of leaving their setups undisturbed -- then the alignment triangle is going to extend beyond the FOV. So you have to iterate the PAA procedure until the target is within the FOV. For example, with my AT8RC and 183, the FOV is about 20' wide. Hard to eyeball the mount to that level of precision, especially with Polaris not in view!

StellarMate has the Serial Port Assistant, but KStars/Ekos on the Mac does not. When I try to connect my CEM70, Ekos cycles through several driver/port choices, including one that looks like an old Keyspan USB-to-serial adapter I used with my CEM25P, one with Bluetooth, and one that looked like it might be USB but didn't connect.

Normally I just use my Pi but occasionally need to connect directly with the Mac. The cameras and filter wheel connect just fine, with no setup on my part. Any suggestions on where to start?

Thanks!

Download the backup from where, though? I honestly don't know where it goes! I also don't actually have an SD card in the thing anymore.

Unfortunately the router thing is a nonstarter for me, since I work in the field so often. I mean, yeah, they probably run off a 12V wall-wart so I could just run one more cable from my battery, but that battery is also running a lot of other things these days!

That's why plugging a cable straight from the computer into the Pi is attractive.

Using the control panel (:3000), I can select "Direct Ethernet" as a networking option. Currently my SM (1.5.8) is set up to use a WiFi network if available, or stand up its hotspot if not.

I would like to make use of the direct ethernet option, but I'm a little concerned about the results if I push the button and then fail to connect for some reason. I can of course plug the Pi into a display, keyboard, and mouse to get access to the desktop, but how would I unroll the direct ethernet setting from there?

I would like to have all three options available, although I certainly don't need them simultaneously. But a little more direction on going back and forth would be most welcome.

Also, I pushed the "Backup" button on the control panel, expecting to see a dialog appear, but of course it just merrily went ahead and did a backup. To...where? My Pi boots off an external SSD, if that helps.

Thanks for your help!

Huh. Thanks. I invariably plate solve to point to my target...wonder what's going sideways then?

And yes, that was what I was asking.

I know I've had this set up before, because I can remember clicking the "equatorial gridlines" button in FITS viewer and having them come up.

But I can't  remember how I made it do it!

Thanks Andrew! I also got guidance on Cloudy Nights to the correct page to get the numbers, but missed the crucial point that PHD wants the rates per hour, not per minute!

So you saved me some serious head-scratching and potentially bad language.
