Focusing rifle sights

[Queequeg 0]

This might sound like a silly qustion but...

Received my rifle today first air rifle but have shot them when I was younger. Anyway I understand that I adjust the windage and elevation turrets if a shot is too high or too far left/right etc but my problem i seem to be having and it may sound daft is that I can see the crosshair clear as but the background is blurry I have tried turning the ring at the rear of the scope but it doesn't seem to do anything.

Am I doing something wrong or is it just becase I am too close? (currently inside house aiming down hallway)

 

Any help would be appreciated.

 

Thanks

Hi, mate.

 

If you're indoors it may well be that you're too close. What scope are you useing?

 

How far away are you trying to focus on?

 

Cheers.

I would say around 20ft (too close?). To be honest I don't know what sight it is or how powerful it is. The writing has worn away and The only writing i can find says something like Model 70 Origional but the 7 could be a 3. The end diameter of the lens is about 2 1/2 inches. apart from that I have no idea.

Is it a fixed power or a zoom? If it's about 2 and a half inch, if that's the inside dia (the lense)then it's a 40mm scope. If you've maesured the outside then it's a 32, either way 20 feet's probably too close for it to focus properly.

Ok i was prpbably too close. I have tried it outside today. But I have another daft question. How is it that when my eye focuses on the background the crosshair is blurred but when looking through at the cross hair it is sharp and the background blurred. Is this just my eyes lol.

Oh yes I think it is a fixed power as the distance stays the same when looking through no matter what I turn.

If you get the focus ring in just the right place mate you should be able to see both the crosshair and the target nice and clear. So you might just have to do a bit of fine tuning to your focus mate.

 

Maybe they could make an auto focus scope like they have on camera lenses.

Heheh that would be good. I have been playing with it here and it seems ok at a distance around 50 yards but when i look back at something a bit closer to me say around15- 20 yards the depth of filed is all to pot and is slightly blurry. COuld just be the close distances.

That sounds about right. Every time you change the distance you need to change the focus on the focus ring too otherwise the scope will still be trying to focus on something 50 yards away.
