The dial is marked for 12 hours with 10-minute ticks, so you can place the pole star at the position given for your location and time. For observers in the Northern Hemisphere, a set of concentric circles from 36' to 44' arcminutes helps you place Polaris perfectly, while a second set from 60' to 70' is included for aligning on Sigma Octantis in the Southern Hemisphere.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eMount-Integrated Adjustable Red LED Illumination\u003c\/h3\u003e\n\u003cp\u003eThe dark-field reticle is lit by a red LED.

For Quick Polar Alignment you use a smartphone app, like iOptron's Polar Scope utility, to determine the exact current position of Polaris. You then simply look through the focused eyepiece and use the mount's altitude and azimuth adjustment knobs to move Polaris to the corresponding position on the reticle. For a rough alignment you can simply put Polaris at the cross hairs; the misalignment is then about 40 arcminutes.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eAccuAlign #3330-SGP vs. iPolar: Optical vs. Electronic Alignment\u003c\/h3\u003e\n\u003cp\u003eThe SkyGuider Pro comes in two versions: #3550 with this AccuAlign polar scope, and #3550A with the \u003ca href=\"\/en-int\/products\/ioptron-3339r\"\u003eiPolar electronic polar scope\u003c\/a\u003e.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eiOptron iPolar:\u003c\/strong\u003e An electronic polar scope that connects to a computer over USB and is used with iOptron's software.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuAlign #3330-SGP:\u003c\/strong\u003e Used by eye with the engraved reticle, together with the iOptron Polar Scope app or the 8408 hand controller to find the pole star position.
