Hello all!

 

I am trying to add my Canon T1i (EOS 500D) into my equipment list in Starry Night Pro 8, but I can't confirm the stats I should use.  The program asks for the "Imager Format" in a Width x Height pixel format, the pixel Size and in Width x Height in microns and finally the Sensor Offset in millimeters.  I would really only like to have this data to superimpose a Field of View indicator to plan widefield shots with camera and lens.  So I don't know how precise this info needs to me, but I struggle to know for sure what I should enter in these boxes.... I really wish the T1i was included as a camera from the list.... I guess it's too old now.  confused1.gif

 

Any help would be greatly appreciated.

 

Dave

Don't need them to provide the info, this is readily available with a google search. Canon Rebel T1i comes with a 22.3 x 14.9 mm CMOS sensor, pixel size 4.69

 

You can also use the free program stellarium as well, that does FOV. I use this for planning.

 

telescopius.com does it as well

 

Sensor size, pixel size and scope determines FOV

Yes, I found the same (22.3 x 14.9 mm CMOS Sensor) but as I stated the program asks for the Imager Format in a pixel format, not a mm size format, unless I misunderstand what the "mm" means.  I had also found the same 4.69 with a Google search prior to posting the question, but again the program asks for the measures in a width and height arrangement.  Maybe I'm missing something easy here on how to convert these numbers?  And yes Stellarium has a FOV as well, but it also does not have the 500D.

Your sensor 4,752 x 3,168

 

Seems kind of dumb, to ask for measurements this way

 

Stellarium doesn't need a 550d, entry. Using all the info already provided you can easily calculate FOV. In fact if you use ANY canon aps-c sensor camera from the list there it will get you 99% of the correct fov.

 

Canon makes a ton of APS-c sensor size cameras, the vast majority are this size. Stellarium already has a bunch of aps-c sensors built in
