Orion Atlas EQ-G Polar Scope
Posted 06 September 2013 - 09:26 PM
Been doing some research into polar alignment, and came up a couple good websites here and here. My question to Orion Atlas owners...did your polar scope come marked or was the hour dial blank...like mine? I'm also curious if anyone might know where I could find a marked polar scope as a replacement. Would one for an HEQ6 work (since the Atlas is basically the Orion version of that mount)?
Thanks in advance.

I also found out that the polar scope from an Atlas will fit into a CGEM mount. When I replaced my Atlas earlier in the year I tried it and it fit with no problem.
Maybe I should post that in its own thread??

The polar scope uses a commonly found M18 x 1mm thread originally used by Vixen.
The hour circle is of limited use being so small and having no vernier scale.
I use Jason Dale's 'Polar Finder' ap for rough polar alignment followed by the handset polar align routine to fine tune it.

And rmollise, thanks for the tip regarding the RA circle. Will be looking at that for sure.
