@Slate okay all of this is excellent, thanks! My needs are of the point-and-wow! variety, whatever I can muster with moderate astronomical seeing problems (near sea level, mixed urban rural terrain making turbulence at night) so zonal defects are probably not likely to be near the top of my list of problems. I'll start poking around here and see what I can find.

@uhoh Yeah, I take mine to a higher elevation, and to be honest after star testing it to the best of my ability (and note: a) the best of my ability is still rather novice, b) I don't have the 500-power eyepiece setup I'd need to properly test)... it seems honestly fine. On the clearest nights I can see one zonal defect, and some SA that is quite hard to see.
After 40+ hours of use the primary source of error is still my skill at handling the thing.
Well, and coma at the edges because it's an f/5 scope.

All of this is really helpful as it's distilled to key insights rather than a book about amateur observing. :-)

Good evening to the prominent members of the Observatory! Long time lurker, long time fan here.
A long time ago (3.25 solar years ago +-.2) I told a friend that I may be able to get star-charts that would be able to show what stars he/they were looking at when they were look up in the sky!(from their hot tub!)

Now I'm feeling bad that I've not come with a good solution. Gondor is calling for your help.

I'd like the map to be usable in a hot tub. Showing the correct map for the season of course.
Also, could I ask this on the main site without being permabanned(well you know, closed no reason)?

Planispheres are made of plastic
...or they usually are, at any rate.
There are more water resistant star charts out there than water proof ones.
