LN300 camera sensor size.

[beamer3.6m]

Hi.

I want to work out the field of view via the 12dstring website but need the sensor size.

I know it's the equivalent of a 6pm eyepiece but this is only ish.

Anybody know?

Does this link help?

Not sure. What numbers do I put in?

[beamer3.6m]

Really confused by the info supplied above.

Where on the sheets do I find the pixel size in microns etc etc.

Totally confused.

Don't think the Sony table [above] is correct for resolution but you get the active sensor size for this 1/3" chip thus ...

IXC672 NSTC 976x0.005 = 4.88mm x 494x0.0074 = 3.66mm which is accurate enough. The PAL version produces the same chip size.

Pixels are slight bigger AFAIK for the Micro but on the same area chip. Hope that helps in your fov calcs.;-)

So that is the sensor size but what about the pixels in microns

That's the .005 and .0074 in Nytecam's calc. 5 and 7.4 microns. AstroAid is an App that will do the FOV calc for you and show you what your image will look like for a given telescope and imager. Hope this helps.

Still confused.

The 12dstring fov calculator has the following boxes:

Pixel size in microns (1 box only)

Pixel size - width - height

So what goes where?

5 is the width and 7.4 is the height.

[beamer3.6m]

Still confused.

Only 1 box for pixel size in microns so how do I enter 5 and 7.4?

[beamer3.6m]

Perhaps someone could fill in the 12dstring form and show me a screen print of the result.

Need to know the focal length of your scope and wether you are using any optical aid like a Barlow or focal reducer. I can give you your Vertical and horizontal FOV for the described sensor.

[beamer3.6m]

Scope is explorer 200p. No Barlow.

[HiloDon]

Scope is explorer 200p. No Barlow.

The FOV is 16.8' W x 12.6' H. A Meade AT Plossl 5mm is 13.5'. A 6mm is 16.6'. This is for a 200mm f5.0 scope. No visual aid.

Hope this answers your question. Let me know if you need more.

I still don't understand how to enter this info myself on 12dstring.

Can someone please explain on the basis that I am an idiot.

Please look at 12dstring and explain what I put in each of the boxes. The telescope bit I can do (explorer 200).

[beamer3.6m]

Also 16.8' arcminutes or degrees etc etc etc.

You can see I am confused.

[HiloDon]

It's in arcminutes which is a fraction of a degree. I looked up the 12dstring program and it only considers square pixels so you have to do the calculation twice, once for horizontal (width) and one for vertical (height). Put in 5 for pixel size and 976 for number of pixels in each of the two boxes. Then submit. You should get 16.8' x 16.8'. That's the width. Do the same with 7.4 and 494 and you should get the height.

What is it you're trying to do with this?

Perfect. Thanks for all the help.
