cervelo Posted July 4, 2006 Report Share Posted July 4, 2006 I am new to shooting and have bought my gun for target practice, it has a 3-9x32 scope. I have noticed when taking aim at a target (approx 15 metres) that the cross hairs get blurred making it difficult to pinpoint my shot. When looking up at the sky through the scope the cross is well defined and in focus, as soon as I line up, my eye focuses on the target and the cross definition deteriorates. The problem is worse at a higher mag. The focus is fixed (i think) the only adjustment I can see on the scope is the mag and the wind/elevation adjusters. Am I doing something wrong? Once I have lost the cross on a target it is almost impossble to get it back without aiming off at the sky and lining up again. Is this something that will improve with time and practice? or is there a better technique for "getting my eye in"? Should I be wearing my spectacles when shooting? (am mildly short sighted) Or maybe this is a peril of buying a cheap gun package? suggestions that don't involve a trip to specsavers would be appreciated.

Theskyfox Posted July 4, 2006 Report Share Posted July 4, 2006 Hi, the fact its 3-9x im assuming that its a variable scope. Try adjusting the magnification to the lowest setting for close settings (3x). I get the same with my scope, (mines 2.8-10), If i use the scope on nearby targets then the crosshairs blurr (or the background) and i have to drop the magnification to the lowest setting. Using full power on a close target is a no no, its probably that your too close. I could be wrong, I mean without looking I can't tell if its normal or a faulty scope. Try it at longer ranges, and try and adjust the magnification until both the image and crosshairs are clear. -Andrew p.s. I wear glasses when shooting, but Ive not had a problem.

stupidsalmon Posted July 5, 2006 Report Share Posted July 5, 2006 Most airgun scopes, for some reason unbeknownst to me, are paralaxed at 100yrds (meaning the crosshairs will be in optimum focus at this distance) It is possible to change this paralax by screwing in/out the objective lense. This can be tricky sometimes, i'll try and find a thread i recently read on re-paralaxing, SS Quote Link to comment Share on other sites More sharing options...
stupidsalmon Posted July 5, 2006 Report Share Posted July 5, 2006 Heres what was said: "How to reparallax a scope Scopes, without PA adjustment, are generally supplied by the manufacturers with the parallax set to 100 yards (50 yards in the case of some rimfire scopes). This is too far for typical airgun use. Ideally for hunting parallax should be about 30 ~ 35 yards. Shorter still for hunter field target shooting around 25 yards being ideal. Fortunately for us most scopes are easy to re-parallax. Here’s how to do it… First set out a target at the desired parallax range. Then remove the end ring on the object lens of the scope. Most will loosen with a firm hand grip, you may have to use a strap tool to loosen the very tight ones. After removing the end ring you will find a threaded inner tube carrying the end lens of the scope. Some can be rotated with finger pressure others will need a flat blade across the two slots in the threaded tube to turn it. I find a steel rule ideal. Now unscrew the threaded lens carrier (moving the lens further out) to reduce the parallax distance. Unscrew slowly till the target, you previously laid out, comes into sharp focus. Fortunately for us the point of minimum parallax error is also coincidence with the sharpest focus at that range. Now the tricky bit, you have to replace and tighten the scope end ring without disturbing the position of the now adjusted inner threaded lens carrier. It may be necessary to use something to locate into one or both of the slots in the inner threaded part to stop it turning as you tighten the end ring. Be careful! One slip and you could damage the end lens permanently if you use a metal tool to stop the lens carrier rotating. Once the end ring is tight again. That’s it, you have re-parallaxed your scope."

caplock Posted July 5, 2006 Report Share Posted July 5, 2006 What about the eye relief adjustment?, usually the eye bell is screwed in and out to adjust focus as required for different vision properties. Is there a locking ring between the zoom control and eye bell? Just a thought, any scope I've ever used has to be screwed completely in to obtain a sharp focus of the cross hairs.

Lancs Lad Posted July 5, 2006 Report Share Posted July 5, 2006 all the answers should sort it out for you matey.......... If that dont work, try taking the mark 1 visual device for a check up. PS, thats your eyeballs.... Quote Link to comment Share on other sites More sharing options...
P03 Posted July 5, 2006 Report Share Posted July 5, 2006 What about the eye relief adjustment Just move the scope forward or backwards on the mounts. PS Don't forget to re-zero P03 Quote Link to comment Share on other sites More sharing options...
