SUMMARY

The discussion focuses on optimizing polariscopic alignment for the NEQ6 equatorial mount. Users report challenges with the polariscope's positioning and adjustments, particularly when aligning Polaris with the North Celestial Pole (NCP). The NEQ6's reticle features images of the Big Dipper and Cassiopeia, which must be oriented correctly for accurate alignment. Suggestions include using a right-angle polar scope adapter or creating a DIY solution with a camera angle finder from eBay to improve viewing angles and ease of adjustments.

PREREQUISITES
  • Understanding of equatorial mounts, specifically the NEQ6 model.
  • Familiarity with polar alignment techniques in astronomy.
  • Basic knowledge of celestial navigation and constellation identification.
  • Experience with DIY modifications for astronomical equipment.
NEXT STEPS
  • Research the use of right-angle polar scope adapters for NEQ6 mounts.
  • Learn how to build a DIY polar scope adapter using a camera angle finder.
  • Explore advanced polar alignment techniques for improved accuracy.
  • Investigate ergonomic solutions for comfortable viewing during alignment.
USEFUL FOR

Astronomy enthusiasts, astrophotographers, and anyone using equatorial mounts like the NEQ6 who seeks to enhance their polar alignment techniques and overall viewing experience.

I have this really beefy NEQ6 mount which, as a second hand purchase, was really good value. Nevertheless I am having trouble using the polariscope 'optimally'. I actually eyeballed the setting (with the tripod on three slate platforms that are very level and firm and pointing to the North and the tracking is absolutely fine for visual after two star alignment.
I found my way to the polariscope, which is, of course, pointing in a totally lunatic angle for viewing from a kneeling position. I found a method which involves lolling across a garden chair so that my eye is more or less right for looking through the scope. But from that position, the Az and El adjustments are awkward to reach and the elevation adjusting bolts are stiff. (I hear they tend to get 'bendy' due to a sub optimal design and that doesn't help). Is it just my aged creaky body or does this happen to everyone?
Now another question:
I went through the procedure and managed to get Polaris in the 'right' place on the circle around the NCP.
The NEQ6 has images of The dipper and Cassiopea on its reticle and, afaics, you have to rotate the reticle so that those images mimic the orientation of the constellations and then frig the Alt and Az to bring Polaris onto the 'spot' on the circle. It seems such a straightforward thing but I guess the method has its limits?

There are right angle polar scope adapters available although they can be a bit hard to find. It is also pretty easy to build one using a cheep camera angle finder from ebay and some bits and bobs,

That could be handy. I might sort out something like that. Alternatively, I could try an alternative way of getting my head in the right place. A sun-lounger, perhaps. But the risk of nodding off to sleep . . . .
