What is my DSLR Pixel size?

[Diddykong]

Hi all,

I'm in the process of working out what my field of view will be for different scopes using this site - https://astronomy.tools/calculators/field_of_view/

However my camera isn't listed - it is a Canon EOS 1300D, what do I need to enter into the pixel size boxes please?

4.29 µm

4.3µm it took a bit to find got it from here https://www.imaging-resource.com/PRODS/canon-t6/canon-t6DAT.HTM

@SyedT beat me to it

Brilliant thank you.  Do I put 4.29 in both of the pixel size boxes?

Yep!

[Diddykong]

Thank you kindly.

I'm trying to decide between the 80ED or 200/250pds for my first imaging scope.  My main interest is smaller galaxies and asteroids so learning towards the 200 or 250pds.  It seems that even the 80ED wouldn't be able to get all of M31 in the field of view?  Is this a bad camera to use for astrophotography?

With your DSLR, if you've a decent mount, good skies and a sheltered site, I'd go for the 250.

We've an old blue tube 250 and a 150 at the same focal length. Much lighter, but you need a lot more time to get the same result with the latter.

My other concern is ease of use.  I've read that an 80ED is a lot easier than a 250.  As long as it doesn't require a degree in physics I can learn the ropes,  I'm located in bortle 6 skies.

I wouldn't recommend a 250p for imaging unless you have a large ££££ mount. Your pixel scale would be 0.74 arc seconds per pixel. So you would need to guide at below 0.4".

The 80ED will save you a lot of hassle.

Hi David,

I'm getting the EQ6-R Pro mount.  Could always go for the 200.  My concern is the 80ED would only be useful for nebula as most galaxies would be too small, could I image with an 80ED then enlarge the image post processing so it was more like the image a 250 would capture? (complete newbie here )

M31 is the largest appearing galaxy outside our Milky Way.. Try using a smaller galaxy and see where that leads....Don't use M101...Its still too big.

Look here for images taken with 80ED's

And here for the Explorer 200P

 

Good luck in your choices.
