Carol,

Looks great, nice job.

Regarding the inclinometer versus altitude scale. The advantage of the inclinometer is that it reads the true angle of the tube regardless of the angle of the base. A base that is even just sightly off from perfect level can introduce errors into your altitude readings, and at least in my case, my eyepiece's widest field at just 1 degree leaves me little room for level induced errors.

You can certainly keep the scale, but I would take great care in leveling the base, and if it were me, I would leave the inclinometer in place during observing as a way to confirm the scale's readings.

Good Luck with the system, I'm cheering for you.
