A Wedge that isn't quite so ... Celestron Nexstar 4SE

Just got a Celestron Nexstar 4SE. It said it had a built in wedge that got me excited in the hopes of carrying out some precise alignment. Looks like the base only has the Latitude adjustment Rod and then you proceed with EQ North align (in my case North). 

 

There is NO Azimuth adjustment knob at all unlike the stand-alone wedge they offer. So unless there is some sort of compensation of sorts to adjust for this in the star alignment procedure, I see no way to achieve precise polar alignment. 

 Does anyone have experience with this? Any workarounds OR am I missing something?

That's about it... for the price, it's in line with what should be one's expectations. Calling it a wedge is a bit of a stretch... "Handy Rod and Hinge" is more like it. You'll need to deftly horse the entire tripod around to (attempt to) finesse the E-W pole acquisition on this one-armed bandit. Customers want cheap, and this is about the only way of providing max possible features on on a tuna fish budget. Come to think of it --- tuna fish has gotten astonishingly expensive!    Tom

Hi natarajanganesan

 

Yes, you'll need to give the base of the north tripod leg a little tap to make subtle Azimuth adjustments.
