Hi all,

I'll be having friends round on June the 6th hoping to see the Venus transit.

It occurred to me that I could put my Nikon D3100 on my scope and, with a suitable cable and software, could have a nice big live picture on my laptop.

Question is... what cable do I need and what software? (Any free software?)

. . . all I ask is a tele scope, and a star to steer it by.

you should have all the required software on the discs that came with the camera and all the leads as well .

Ah... ye-es... time to go back to the 224 page manual.

Thanks ;)

(My brain hurts - I'm trying to learn too much at once... how to get the best set-up on my scope, how to use my planetarium software to control the scope, and how to get the best out of the camera - plus viewing on the laptop. All before the rain stops and I get a viewing night.)

But stick with it and it will all start to come together.

Oh I'll be sticking with it all right! ;)

Hokay... I have "a" cable - but the manual ONLY talks about uploading photographs already taken from the camera.

So can I watch "live" from my Nikon D3100 DSLR or am I going to have to get a webcam, or something? I'd really, really, REALLY like to be able to output my camera's live view to my laptop.

That probably explains why there's nothing in the manual ;)

Bummer.

Ok... so I've got a webcam I don't use... where's the nearest tutorial?

I would have thought having 'Live View' and USB 2 output it should be possible, but I don't have a NIKON, I have a Canon, I plug in my USB 2 cable in the camera and Laptop the software comes up with options and I press live view and away it goes.

Sorry not much help

Doesn't seem to work that way with my Nikon. I tried it already :clouds2:

Erm, nope.

They're talking of editing pictures that you have already taken. The camera has a number of on board image editing options - the software they are talking of looks to be more flexible.

The clincher is this...

I should point out that the D3100 cannot be controlled from your Mac or PC, unlike Nikon's more expensive models.**


So it seems that I cannot watch my live view on my PC, nor use software such as SharpCap to grab the movies.

**<grumble> At over £400 I'd call this model expensive! Sheesh!</grumble>

So what would be the route to go...?

A different Nikon, or a Cannon equivalent?

It's a good camera, just won't link up live view or movies with a computer.

One thing I've yet to try is the multiple photo option. I'd get a stack of full size .jpg's (4608x3072) that R6 or AS2 should be able to work with. For planetary shots that might turn out to be amazing.

Oh and the videoconverters I have would be able to batch crop those images to a size the stackers could deal with.
