I've changed from an AltAz to a EQ (CGEM) mount not too long ago so inevitably I'd had to run in some questions sooner or later.
I "thought" I had the polar alignment thing right, turns out slewing to deep sky objects did not work satisfactory. The polar scope itself needed calibrating, for which I found a very helpful YT tutorial. It's fine now. But it actually left me scratching my head still.
I compared the position of the NCP in relation to Polaris in Stellarium with that of the image through the polar scope around the same time (Cassiopeia dialed into the same position/time/date) It appears as if those two are 180º off.
-Stellarium has the NCP above Polaris at date/time 'X'
-The polar scope reticle shows NCP below Polaris at same date/time 'X'
-In both cases Cassiopeia is at approximately 05:30 Hrs positioned of the NCP. (So below the NCP but rotated around NCP ± 20º CCW
This seems really odd to me and confuses me. How is it possible? I get the idea that my pointing and tracking errors are due to the fact that I am aligning to the NCP on the (180º) opposite of Polaris.
Please find attached pictures of what I mean: an image of the sky today at 00:00hrs and the view through the polar scope dialed to the same "time". One can see NCP is 180º off.. I thought of optically reversed image but that does not count as it relates to its orientation to i.e. Cassiopeia.
Scratching my head is Stellarium wrong? ..Hhmm prolly not. Is my polar scope wrong? Prolly not.. I'm wrong.. but how???
Anyone care to enlighten the confused man ? I added the images of what I am seeing to this post.
Thanx a bunch in advance everyone
