1. The Forum Rules have undergone some minor changes and updates.  Please take the time to read them; it will only take a couple of minutes of your time. By doing so, you lessen the chance of incurring the wrath of the moderation team or making yourself look foolish to other members.

    90% of users posting adverts in the Sales forums need to be reminded to read the rules as their posts are wrong.  This is unnecessarily time-consuming and will no longer happen - if your advert doesn't follow the Sales Rules it will be deleted and you'll have to start all over again.

    Thank you.

Even if this is just your own personal opinion, RESPECT YOUR FELLOW MEMBERS.'

  3. Dear members,

    Our membership (like our country) consists of people from all walks of life; different in far more ways than can be listed here and each with a different view based on their experience of life - regardless of their colour, religion or cultural heritage. Every single person in the UK has been born of mixed race – we are a multi-coloured and multi-cultural country.

    As many of you are aware there are a handful of individuals amongst this membership that persist in making provocative, inflammatory, racist and otherwise offensive comments. This has been happening across the forum to a certain degree but is most especially prevalent in the Adult section.

    The moderation team has tried to stay on top of this, however unfortunately because of the ‘offensive’ nature of much of its content we don’t monitor the Adult section quite as much as perhaps we should. As a result much of this behaviour has gone unnoticed unless it has been reported to us. While the team always intended to take a "light touch" approach to the Adult section it would seem that some people aren’t quite adult enough to be left unmonitored after all.

    This behaviour is, and always has been against Forum Rules as well as the specific stipulations of the Adults forum and it will no longer be tolerated. We feel it's time to draw a line in the sand and as such from this point onward offenders will receive an immediate and permanent ban from the forum.

    In order for us to achieve our goal of restoring the forum to the friendly and tolerant place it once was, we ask that ALL members be mindful of the content they post and help us to stop unacceptable behaviour by using the 'Report' tool at the bottom of any offending post - the results of which can be seen only by Admin/Moderators.

    You should all receive a copy of this message by PM.

  5. Postings on Politics, Religion & Controversial Off-Topic Material

    The majority of users do not want to read about these subjects and people have left the forum as a result of it – this is after all an 'Airgun' Forum. It’s all very well to say they don’t have to read it if they don't want to, but as most of us use the ‘New Posts’ button there is no easy way to avoid it.

    All AGF staff members are in favour of people being able to discuss what they want, but we have to draw the line somewhere if it is upsetting other users. We don’t want to read about these topics either.

    IMPORTANT- The discussion of politics and religion is no longer allowed anywhere on the forum (including the Adult section).  The only exception is if it's airgun related - they must be put in the Airgun Related Politics section..

    We will not tolerate bullying or personal attacks, racism or any other offensive 'isms'. we will remove these topics from the forum, we will not give you an area where you can abuse each other. We will not hesitate to ban offenders.

    Afternoon Chaps,

    I have put this on the other forum, but struggled with uploading fotos

    Whilst waiting for the bits for my NV Addon to be machined, I thought I would put my spares to good use. I am having issues though with interference from the driver and I am actually disapointed with the range on the 5-100 lense. I am going to finish off the battery housing and tidy up the wiring, should be ready soon.

    Any ideas on the range from the camera lense, am I doing any thing wrong? Can I use extra cs spacers?

    In daylight you should be able to focus the lens from as close a 1 yard out to infinity. If you want to check that it's far enough away from the sensor try unscrewing it a bit and see if the focus improves, you can add extra spacers if required but really they shouldn't be necessary.
    I would put some black tape over the holes in your Crelant head, there's alot of light leaks out of them and will spoil your picture.
    I don't know if it applies to all of the CS lenses but on several that I have tried and from reports by others it would seem that you can't actually wind them all the way to maximum focal length without it going horribly out of focus, just back it off a touch and all is then ok.
    You can check whether your lens is a C or CS which although both have the same mounting thread need to be set at different distances from the sensor. The mounting flange to sensor distance for a C mount is 17.5mm and for a CS mount it's 12.5mm.

    Thanks Terry,

    With regards to the light leakage, I will tape up the holes as recommended. With regards to the lens, I thought I would be able to really zoom in on objects at 100m plus. But the magification does not seem to be there. I will keep experimenting.

    If I remember correctly a 100mm lens on a 1/3" sensor camera is somewhere about 8x magnification, it's not as much as you would expect unfortunately.

    hi flykilla, have you remove the ir cut from camera, not doing so will reduce range and also make focus tricky when only light available is ir re interference this can be a problem when torch and cam /viewer all from one battery, nice idea for mounting the sanyo evf, have you tried to adjust brightness and focus on evf, to dark or light will affect the view range to a degree,are you running torch at 12v or v reg down could be the v reg giving the interference

    Hi Genisis, The camera is a watec and does not have a IR filter. The picture quality is fine and I have messed about with all of the setting on the EVF to get the best picture possible. Its only when I turn on the IR that I get the lines across the screen. I have just bout 3 new drivers, so will try them. The battery I am using is a 11.1v Lipo. When fully charged, it gives 12.6v. I never let the battery go below 12v.
