question

is it any adapter to attach this device to a SLR camera?
Asked by: Anonymous
Yes you can get the Barska Telescoping Digi Adaptor. This will attach a DSLR Camera. Mount a point-and-shoot camera or lightweight SLR to spotting scope, telescope, and monocular eyepieces. Website link: http://bhpho.to/1CGku0f

Asked by: John W.

question

i do shooting mainly at 25 and 100yards distance. will i be able to zoom in to see the bullet holes at this distance?
Asked by: Anonymous
The glass quality is too low for shooting/viewing targets at 100 yards. I can see the holes much better through my Vortex 2-7 rifle scope or my 10x Nikon Monarch 5 binoculars. I tried using it a couple times. Not impressed. I'm in the market for another lightweight spotter with better glass.

question

is the eyepiece interchangable with 1.25 inch eyepieces?
Asked by: Anonymous
This model does not have interchangeable eyepieces. It's a dedicated eyepiece.

question

are there any camera attachments for this unit?
Asked by: Anonymous
No - I cannot see a way to connect a camera to this scope - it is very basic. While it may be within the realm of possibility , you'd have to concoct some sort of rig on your own. It works relatively well out to about 50 yards, in my experience on the range. It has done a great job for me and others looking to zero a rifle Marine Corps style (in the sense you zero at 50 yards/meters and you're still good at 300 yards/meters with 5.56 bullet drop). I can't complain about it for the price - it does the job, and it fits nicely in a range bag. As I have seen with optics, if you want a camera attachment, it will cost you a bit more. Of course, you can go from reasonable to insanely expensive with optics, either spotting, or scoping - I'm sure that's not relevant or helpful to this question - but if you're looking for something specific to film or photograph, this isn't the device you're looking for. You'll need to tack on a few more zeroes for sure. Best of luck! :-)
