Quote:Anyone kmow why the Local mean side rail time is different between ioptron app and the Scope Help app? It's off by almost 22 minutes. Wondering if this could be the error I'm experiencing with my vixen polarscope. What time should I use to set up my vixen polarscope? UTC, LMT or ET? Thanks in advance.
I'm using this with my new Polarie.

Quote:I believe I am as the longitude is from the GPS of my ipad. According to the Vixen manual I should be using an offset of 5 degrees but the location of Polaris on the Vixen reticle does not match the orientation on the ioptron app. It matches only if I use a 21 degree offset. Is 21 degrees the right offset for Toronto? Thanks in advance for your help.

Quote:Dave, here is the link and thank you for your help. http://www.vixenoptics.com/PDF/POLARIE%20Manual.pdfSorry for the confusion. Page 24 summarizes this procedure but I just cannot get the reticle in the polar scope to match the orientation shown on the ioptron app on the ipad.
Quote:Yes. Its very useful. The view is inverted. The other app I also use is Scope Help which is free. They both give the same result for orientation of Polaris. Unfortunately, I'm trying to replicate the reticle on the Polarie polarscope and I'm failing...operator error I'm sure. Thanks again for your help.
Quote:The offset is described in the manual as such: Meridian offset scale (Adjustable between E20 and W20 at 5-degree increments)This is directly from the manual...Check the difference between the standard time meridian ofyour region and your observing site before you set up the Polarie.If the observing site is east of standard time meridian, rotate the time meridian indicator in the direction as indicated E on the meridian offset scale.3If the observing site is west of standard time meridian, rotate the time meridian indicator in the direction as indicated W on the meridian offset scale.Hope this helps....
