This is not a how to on Polar alignment so if that is what you are looking for then sorry to disappoint you. I assume you already know how to Polar align your telescope and so I will not repeat the process here. Of course if you know how to Polar align your 'scope then you will also know the awkward positions you end up in trying to peer through the polarscope to locate Polaris.
So here is my bodge.
Total cost approx £31. Similar items can be purchased on the Internet for up to £114.oo they do however have a nice adapter to fit to the polarscope instead of a plastic drinks bottle top.
A search on the Internet revealed that many people have this problem and there are a number of possible solutions but one which had some appeal was the use of a right angle finder for a DSLR. Many people have used the Seagull finder but I found the Neewer finder was a bit cheaper so ordered one from Amazon. The next stage of the operation was to connect the finder to the polarscope for this I used the top of a flip top drinks bottle which was just 30mm diameter and so made a snug fit over the end of the polarscope. Some careful work with a craft knife and I had removed the nozzle.
Fixing the cap to the finder relied on a Nikon adapter which had two threaded rings which could clamp together. So the first ring was put on the adapter then the bottle cap, then the second ring was tightened up and the cap centred to the adapter.
Putting it all together and pushing onto the end of the polarscope and now I can see Polaris without having to sit on the ground and crane my neck up at an awkward angle.
Ok so the view is a little restricted but not as bad as is shown here as this was all I could see with the camera, but I can see polaris so alignment is simply easier now. At the end of the day I have the use of the finder for the scope and the camera. Some bodges I saw lost the twin magnification functionality for the camera but this idea keeps it.
