Re: iOptron SkyGuider pro
The above object is Omega Centauri, RA: 13h 26.43 m, Dec:-47.46 Deg. This time the mount is guided via a lighter guider set up.
SkyGuider Pro Dec arm is too weak for mounting all the above stuff without doing a proper modification, and attached items might just fall off if not careful.

Re: iOptron SkyGuider pro
For EQ mounts that do not come with digital setting circle, an alternative way to search for deep sky object is to use "Digital Level Meter Circle setting". This required manual computation of Hour Angle H.A. in which: ((H.A. = LST - RA of the object)). LST implies Local Sidereal Time, RA ...

Re: iOptron SkyGuider pro
No guiding for this, due to weight consideration, Alt Polar alignment done through putting Digital Level Meter on mount top surface, Az polar alignment was done through Meade 12 mm illuminated eyepiece this round (to simulate situation for forgetting to bring guide scope), so it was found to be a li...

Re: iOptron SkyGuider pro
I just owned a Ioptron SkyGuider Pro recently, measured its Periodic Error at 40 + pk-pk but found it conflicting to my actual test, surprisingly, my actual test on Pollux for 2.5 mins shot at ISO 100 found stars to be as good for mount that is of 20 + pk-pk, don't know what went wrong. https://farm...

Re: Polar aligning an ioptron SkyGuider pro
I used my imaging scope (420mm f.l.) to test the mount Periodic Error for better resolution, the curve looks much smoother than earlier one. n.b. This mount is already heavily loaded when i put this 2.3 kg scope (with scope rings + dovetail = 2.8 kg), i should not add in the guide scope at the same ...
