OK, that's pretty clear guidance. It wasn't just the dollar cost I was thinking of, but also potential power consumption and heat generation. That might be significant on a less-sophisticated board computer where the RAM is a bigger part of the budget for both, but thinking about what the Pi 4 is already packing, I bet the extra RAM 's power and heat is down in the noise.

Thanks again! Me for a 4-gig Pi!

I'm contemplating replacing my Pi 3 + StellarMate with a 4. Will plate solving, etc. function OK with 1 GB or am I better off with 2 or even 4? The 3 takes a long time to plate solve and often fails, so I have to use my laptop and suffer the download times.

I have never gotten Ekos to park my CEM25P properly. Maybe it's a UTC/local-time issue, but if memory serves it does weird things in DEC too.

OK, absolutely no promises but if I can scrape up some time, I'll see what I can see.

I'll have to do it on the down-low, though. Otherwise I'll get The Look from my wife, and "That's great, dear. What project are you giving up to make time for it? Hmm?"

Oh shoot, late summer is Crazy Time for me with Ski Patrol, we also have a release coming up at work. Otherwise I would love to get in on this. In very general terms, what's the build environment like for Ekos? I live mostly in Visual Studio these days but have certainly done time in gcc-land as well.

Rick Wayne replied to the topic 'What is your imaging workflow when using Ekos?' in the forum. 5 months ago

My CEM25P has a pretty good polar scope, but the Polar Alignment Assistant invariably does a better job than I can with the scope. Well worth the five minutes IMHO.

My workflow is close to those above; since I do a lot of narrowband these days, I'll note that I usually do a rough focus using the scale on the Stellarvue's focuser and rough polar align with the scope. Then, using one of the broadband filters so that short exposures suffice, I'll focus by eye on the stars around Polaris enough that plate solving is reliable. Then the Polar Alignment Assistant to really dial the alignment in (usually to within a few tens of arcseconds).

Next is Capture & Solve/slew to target on a bright star such as Vega. Once I've got that centered, I switch to the taking filter, slap on the Bahtinov mask, and compose my soul in patience for frames to download.

That flow lets me do most of the plate-solving and get close to the focusing mark using short exposures through the R, G, or B filter, and get centered on something bright enough that the diffraction pattern will be usable with only sort-of-long exposures through Ha or OIII.

Polar aligned and focused, I'll either do Load & Slew, if I have a previous FITS of the target, or select the target in KStars and do Capture & Solve. (The former is excellent when I'm pointing elsewhere than the officially accepted center of a target, e.g. my Pelican/N.A. of last night). Might have to use longer exposures to ensure a solution, but that's OK, usually it only takes 2 or 3 frames and it's all automated -- not like sitting there watching the screen with your hand on the focusing knob, waiting for the next frame to finish so you can see whether to turn the knob or not.
