ETX-70 Misaligned Tube?

I am borrowing an ETX 70 from a co-worker who no longer uses it.

In going through the usual fiddling with "my" new toy, I discovered that there was a slight inconsistency between what the manual said was supposed to happen. It mentiones "home position" as being with the OTA in a horizontal position and 0 degrees on the declination. Unfortunately, when the tube is horizontal, its more like 5 degrees. I have attached a picture of this.

Being that its cloudy, I can't test it out. Not sure if I even want to bother if things are misaligned.

I have two questions.

a)Is it misaligned and can/should I fix it?

or

b)Does it even matter so long as the tube is horizontal when I start aligning it?

This is my first foray into goto scopes and I have been thinking about getting a larger, nicer Goto GEM for my SCT.

Hi Zach,

The setting circle ring can be rotated by loosening the large knob on top of it, so it is not a fixed reference point. When leveling the ETX a small bubble level will work best, but you can probably get close enough just leveling it by eye given the short focal length of the ETX70.

So to answer your questions directly:
a. It is not "misaligned". If you want to use the declination circle to level the tube, just loosen the knob slightly, level the tube with a bubble level, and set the circle to 0 or 90.

b. Alignment and GOTOs will work fine just leveling by eye or a bubble level. A "level"/horizontal tube is your goal.

Have fun
John
