Scopeless

Post by spike589715 » 13 Sep 2013, 19:03

Hi guys
I have a scope based night vision system that I built after reading lots of tips here and it works great
Got a rabbit at 40 yards with is so all good

http://www.theywalkamongstus.co.uk/airg ... ision.html
I have since updated to the watec camera which works well

I have been thinking of going the next step ... Scope less ...
Is there a recent thread with the current thinking on the way to go on this ? Best cross hair gen etc i have a Sony board camera 1/3 would that be good enough ? What is the recommende lens ? How much mag can I expect to be able to use

I read somewhere that there was an arduino based gen, has anyone tried this ?
I have a screen and illumination etc

Has anyone tried a 2.5 inch screen ? I am currently using a 3.5 and it is a bit cumbersome

Thanks for any pointers

Simon

or here if you dont want to wait for the slow boat to get here :thumbup: http://www.stockoptics.com/cctv-lenses/ ... older.html

simply unscrew the 12mm lens holder and replace it with the cs holder

I have got a new cross hair generator to test, it has about 15 different reticles and a separate adjuster for zeroing, the spec is very good and I just need a bit of time to hook it all up for a test. Some info here viewtopic.php?f=29&t=3848

Hi
Has anybody got any thoughts / links for good lenses to use with the watec or Sony 1/3 cameras ?
I am keen to get cracking on this
I can start by looking at the mounting of the camera and lens
Do zoom lenses work ok ? Does the zoom effect the poi
I can put a cross hair generator in after - would be good to be looking at the mounting options

Thanks for any ideas etc
Simon

You can use a zoom lens but you will need to lock it at one setting as it's 99.9% certain than any zooming will alter the poi, the same goes for focussing. It seems best to set the focus at night using ir at the range you expect to be shooting. In daylight you can close the lens iris a few stops which will give you increased depth of field to cover the change from ir to daylight.
For lenses you need to decide what type of lens and what focal length (which equates to magnification) and then you can start to look out for the most sutable.
