Re: HELP

I opened the iris and unscrewed the lens almost to the last thread and I can see a lot better far off so I'm guessing it is to close to the 50mm lens so I'm going to have to do some adjusting on the camera and the lens to vet them farther apart Ah - I'd not looked back at the video and forgot it wa...

Re: HELP

Hi, Welcome to the forum. Have you removed the M12 lens from the EJ230 and most of the threads that secured the waterproof lens cap? I sounds like you have the 50mm lens too far from the CCTV sensor to focus at longer ranges. Aim to get the rear flange of the lens about 15~17mm from the sensor (not ...

Re: Does DIY nightvision affect accuracy?

Thanx for your input somebloke. I figured it had something to do with parallax. My scope does NOThave an adjustable objective. I read somewhere that you can remove the objective bell and screw the i.d. ring ompit to adjust for parallax. But they cautioned that some scopes will release the nitrogen ...

Re: Does DIY nightvision affect accuracy?

Maybe its my dyslexia but its not clear to me if your scope has any means of, shall we say, quarry focus. (AO or sidewheel) If not you will only get decent results at a set range, and note: That focus range will be closer under Infra Red light than in daylight: So if you are using the ocular to try ...

Re: Thumbkey strap DSCA's now available

I've had a few people ask me if the Floplast fitting is glued into the main tube: It is not. :angel: The main tube I'D is machined to make the Floplast end fitting (which carries the E700 camera) a nice tight fit so it allows for extending the eye relief if needed by up to 22mm for longer than usual...

I have a mate I think he can do it for me, If knot I will have to take to the gun shop.
Thanks for your help. Pete.
