Canon number

[Anthony1979]

Does the camera get better when the number goes higher.... ie is a canon 4000d better than the lower number like 300d...

Depends on your definition of "better"

This might be useful by way of comparing some of the major features: https://en.wikipedia.org/wiki/Comparison_of_Canon_EOS_digital_cameras

Generally the less digits (not lower number) the better the product line. 80d better than 800d but 8d better than both etc.

In general the the four digit cameras like the xxxxD are basic entry level models, the three digit ones xxxD have better noise performance and more features like mirror lock up, the two digit ones are usually a more rugged have many more features like micro focus adjustment for lenses etc, the single digit cameras are the pro models..

The first number is usually and indication of manufacture date so the series might go something like 300D/400D/500D etc with all the models having similar design features but big improvements in performance with each step..

I didn't realise this when I acquired my 1200D. Probably not the best for astro but, to be honest, I'm not getting the best out of it for terrestrial use either!

Anyway, I think user skill is of greater importance than camera spec!

This link leads you to Canons DSLR line . Starts with highest price down to cheapest and in that order camera numbers listed .

Thank you.. im just thinking about getting a 450d

[Anthony1979]

Or would the 40d be better

[celestron8g8]

The 40D is an older camera . If you can get a 450D that would be best to go with .

There isn’t much in it at 2007 and 2008. The 40d is a very good camera. The bigger magnesium body of the 40d might help it run a bit cooler inside.

Here is a good website for comparing DSLR type cameras in their specs / performance for AP:

http://www.photonstophotos.net/

this page in particular:

http://www.photonstophotos.net/Charts/Sensor_Characteristics.htm

Running 40d vs 450d comparison gives this graph:

Both have rather low QE at 31-32% ...

While we are at it, what do people think of Canon M100?

It is entry level mirrorless Canon model with rather good specs. It is also fairly cheap, B&H lists it for $350 new - I'll throw it into comparison mix:

It is very light weight (no mirror and slim body) - 300g with memory card and battery. It has almost double quantum efficiency of these two models - at 56% and it has lower read noise (both types although I don't really understand DN expressed read noise after conversion here) and similar FW capacity at 30K

Might it's size mean it could run warmer perhaps

I should add that the above is a generalisation of product line not a reflection on astro suitability.

I find this matrix useful - from the Astrophotography Toolkit user's guide:

https://ideiki.com/astro/EOS.aspx

It shows you year of manufacture, and processor generation.  Notice that the 450D has live view but doesn't support video.  I have a 400D (no live view) and am looking to upgrade to a 70D.

So its better just to get the 450d

Or a 40d. Both very similar. 

[happy-kat]

I would work the other way, for the budget in question what are the options available

[Anthony1979]

Im only looking at 100 second hand

[Anthony1979]

The only thing with the 40d is the sharper count... Its cheap than the 450d but the count is nearly 30,000

40d - plenty of ebay. £80, shutter count 80k. Plenty of life in it still and when you get bored of it, you’ll still get your money back (or maybe lose a tenner at most)

To be honest I had two 40d running side by side, one with 6k and one with 70k, there was no difference in the quality of the images. The shutter sounded slightly lazier in the higher shutter count, but it doesn’t really matter when you’re taking 300s exposures.

You should be happy with either.

Not sure which one to get now

You came to the right place to get confused Anthony 😂
