Help with No32 Mk3 scope setting focus

[Merlin266]

Managed to re focus the graticule, however the peripheral of the image goes slightly soft

Ah....... Here's the bit some owners don't like to hear. But in a workshops the telescopes are focussed on an optical screen for perfect ocular vision. A bit like accuracy testing the riflke on an Enfield rest where all human interference is removed. Some owners dispute this, saying that THEIR optical vision is perfect and better than the optical standard vision of the light screen! And dare I say it, that it might appear that yours ain't............. It's a bit like telling the wife that she's crap at parking. There's no good way of telling her............

Here we go again............ What you have to do is move the erector cell fore and aft moving your eye left and right as you do so so that at a certain point, the point of the grat is flat on exactly the same focal plane as the image. That means a total lack of parallax. However, there is something else. You have to remember and it's this can also affect the ultimate focus of the image. After all, it ain't a 'target' you are seeing, but an optical image that your eye has.................. Anyway

I'm sure that I have been through all this before................................

I said in thread 13 that the hole in the locking segment is threaded to ease removal. It seems that some AREN'T! So apologies there. I have just removed one that definately isn't and never has been threaded. Luckily it came out quite easily after being held against a hot soldering iron for a few minutes. So there you are. They SHOULD be threaded but some definately aren't!

So apologies if anyones been looking for the missing thread
