Re: photon RT zero

Assuming you have a 6.0 x 50 then 1 click is 9.4mm @ 100 meters .

so Y=-46 should put you 18.8 mm high (3/4 inch) @ 100 meters .

You don't say what calibre you're using but that should be point and shoot for Photon ranges.

Re: Nv Advise

Hi, keep changing my nv and currently had ward d700 and d800 but found that they were a nightmare for staying on as most of my night shooting involves long walks! Had photon xt and rt but found quality not great close up! Done add-on screen from some bloke but again too bulky! Done pulsar n870 and ...

Re: Pulsar 860 rt which Ir

I was hoping somebody would give you a good answer to this. I have a 860vs which I assume is the same without the wi-fi and recording. I'm using a 25mm aperture ( which I drilled in an old spray can lid ) which sharpens up the picture a lot. Currently I'm using a Tracer 400 for illumination but I ha...

Re: help with photon xt

Why is everyone suggesting taking the centre out, that is only on it for daylight. The cap should be taken off when using i.r at night, surely? Photons may vary in their sensitivity but I find - daylight = pinhole , twilight = centre out and dark = cap open. I think most people can understand the c...

The XT centre cap doesn't pop out.
Mine does - bought spring 2016

Re: Magnification

I have used a Quantum XD19S and a Helion XQ50F. When atmospheric conditions allow the Helion is incredible but if it's a bit misty you can easily miss heat sources especially if the focus is off. The Quantum XQ38 and the Helion XP38 are probably the best compromise but I've yet to try a Quantum Lite.

Re: Photon RT wind / elevation adj range

The RT is +/- 50 "clicks" whereas the XT is +/- 30

BUT the 6.0 RT is 9.4mm/"click" @100m (940mm total) whereas the 6.5 XT is 17mm @100m (1020mm total)

So slightly less adjustment range but finer adjustment is possible.

Re: PULSAR HELION XQ38F

Your not the only one - I've been trialling a Helion XQ50F and having exactly the same problems . I'm also finding the "objective" needs constant refocusing as you scan over changing distances. Everybody that has tried it prefers the XD19 that I usually have.
