Originally posted by fewayne My iOptron CEM25P mount, like many others, can talk to a computer via the serial port in its hand controller and a USB-to-serial converter box. I selected KStars/Ekos as my astronomical software because I wanted to run a Raspberry Pi in the field and not depend on my laptop's batteries. With no other hardware than that, I can use Ekos's polar-alignment routine and usually nail it within a few seconds of arc within ten minutes or so. You simply point the scope roughly at Polaris, and the s/w shoots a series of three images, does plate solving to figure out exactly what's in the picture, and then does the math to determine where the polar axis has to be pointing in order to yield those particular results.
It sounds complicated but in practice it's really simple. I had to download and install some of the plate-solve index files, but other than that it was pretty turnkey and the actual process is really pretty simple. iOptrons have a pretty dang good polar scope but this gets me to MUCH better accuracy.
I use the guidescope and guide camera for this since the lower magnification does not necessitate as many index images, but if you download the extra indices, it works perfectly well with your main imaging scope too.
HEY! another indi user!
Proud contributor here.
I got aligned on the dumbell nebula in about 2 minutes from home startup tonight thanks to ekos plate solving.
Between the Onstep (diy) team(my guys), Jasem Mutlaq(the head lunatic), and his friends, and a few other crazy dedicated contributors, not to mention the Kstars team, this thing is really starting to shape up!

It'll take me until I'm 50 to get to the kind of gear I'd like to be using at this rate. Heh.
I was planning on getting a guide setup but there is also software I'm wanting to get, there's the need to now fix my mount, there's other camera lenses and filters I'd like to get... the list goes on. It's always hard to choose!
I think indilib stuff may port to mac. If not then you could be the guy who makes that happen. (excited)
As for guiding, I recently took the inline 8x50 from my TPO scope and crammed a 2inch male into the back (after some grinding) to make a guide scope from an unused inline finder scope. THe adapter to m42 let me srcew on an ASI120 and it' been working well. Better than my diy mount will handle.
