Canon 1100D or 100D for Astro imaging?

[William Jones]

Hi Guys

I want to do prime focus Astro imaging through my Skywatcher 200p Newtonian.

I have the option of buying either a Canon 1100D body or a Canon 100D body.

I realise that the 100D is 18 megapixel compared to the 1100D which is 12 megapixel.

In your opinion , which should give the better results?

thanks in anticipation

I think most people would say the 100d is the better of the two.

Hi Will,

Thanks for posting.

This may help you in your decision making-http://cameradecision.com/compare/Canon-EOS-100D-vs-Canon-EOS-1100D

I have not used either model but do own a couple of Canon DSLR's so am conscious of features that are astro-useful and which not.

As Peter CPC says the 100D seems the better of the two; depending on how you intend to use the camera the better 'LiveView' screen may be of importance to you. It is slightly lighter in weight too and more modern manufacture.

I was intrigued at the data here-https://www.sensorgen.info/ as the 1100D has a much greater well depth and larger pixels. The 100D has the greater QE however. It would indeed be very interesting to hear from someone who has used both cameras in the field.

Best Regards,
Steve

Hi Will,

Been imaging with the 1100d for some time and very happy with it. Wife treated herself to a 100d so I thought it rude not to try out the higher ISO rating...... just to make sure it worked you understand!!!!.....  As already mentioned, 100d is lighter and the touchscreen back is useful for altering settings quickly. Two comparison photos are below. My image processing skills are fairly basic so images are only slightly tweaked from original RAW shots.

Can't go very far wrong with either body so cost may be final choice.

Either will do very well indeed. However there may be a third option to throw into the mix.
If you are only looking to do short single exposures then this should not really apply too much but if you are looking to do longer exposures its worth considering a 600D.

The 600D has the same sensor as the 100D However, The 600D is a slightly larger body and from what I understand gives less thermal noise at longer exposures.
I have a 600D and have been happy with the results, take a look here for a good comparison of various Canon models side-by-side

Regards

Plus the 600d has an articulated screen.

Correct me if i am wrong,or maybe i am doing something wrong,but raw images wont work with the 1100d in DSS.

[happy-kat]

They work fine, of they don't you are using an old version of DSS. You need 3.3.4 or higher

I've got a 450D and an 1100D - I think you need to install a Microsoft Codec for CR2 raw files.

[happy-kat]

With an 1100d it will only give proper stacked image in 3.3.4 or higher if you don't you get a long narrow image.

[Stub Mandrel]

This has now become academic... DSS 4.1.0 has just come out of beta and is available in 64 bit.

 

But you may still need the codec!

I'm really happy with my 100d..i bought mine from Juan  (cheapastrophotography) modded and ready for action..its not let me down yet...

I find it works best at 400-800 iso and 1600 in HA  also milky way on a static tripod..brilliant camera

Thanks for the replies guys. I think I will opt for the 100D.

How much and who is the best for performing the Astro modification to the camera?

Took me over a week to figure that out.

You don't have to, I have 3 and 4 side by side

I did too when I discovered the bug as 4 wouldn't work without 3 present (I think it was an update I downloaded) however a few days later my hard drive died so I had to reinstall everything. That's when I found a version of 4 that works alone.
