Thank you

If you mean in terms of field of view, then this site can help you with that: http://astronomy.tools/calculators/field_of_view/

Select imaging mode tab, use "custom scope" then adjust the focal length field accordingly.  The canon 2000d isn't an option either, but if you select the 1000d which will have the same chip size that will give you an accurate representation.  Here is what M31 would look like at 300mm:

 

That is how it would be framed, but in terms of detail etc, that depends on your exposure length and how many images you stack together.
