But I do not know if the additional expenditure will significantly improve the images I can take or not.
The 450D has an LCD with only 0.23MP, The 1200D has 0.43MP and the 550D has a whopping 1.0MP.
Apart from the 1200D (2014 entry model) being a bit larger and having half as many LCD pixels as the 550D (2010 mid-range model), I see little difference between the two. I presume that despite being 4 years apart they still use the same CMOS sensor?
So my questions are . . . . .
1) If I paid more and got a 550D or a 1200D with Digic 4 processor, would I get a significant improvement compared to a 450D's Digic 3 processor?
2) Does having more LCD pixels make it easier to focus Live View on the night sky?
3) If I went for a Digic 4, other than the physical size and LCD pixels, are there any significant differences between the older (2010) 550D mid-range model and the newer (2014) 1200D entry-range model.
Many thanks, Geo.

I knew about much of what you wrote but not about remotely controlling the AF.
You contribution is most appreciated, just as it always is. Yes I posted here after over 48 hours of getting numerous reads but no replies in the other forum. I was most surprised not to find someone with first hand experience as I thought these Canon models were actually quite popular amongst Astro Photographers. But today I did get 3 replies from people with experience of one of the models.
Plus my daughter is just starting a job in Astronomy Research where dozens of her colleagues are most probably magazine subscribers and members of this forum too.
Sadly I have been forced to use the other forum as I am heavily restricted to what I can post here. As a junior member I am restricted to how many words I can start a thread off with. ...
cannot post images. Cannot post URLs.
I am optimistic however that this will improve with time though.

It just has improved.
I just been allowed to post my first URL for John who is a new member and struggling to do anything with his scope. AWESOME.
Yes you might be right, people of her generation are so tech savvy that they probably only subscribe to online magazines. But I assume that at least some of the professors at her institution will be nearer our generation and actually read real paper magazines?
That said I would be surprised if the SkyAtNight magazine was not downloadable in digital format for subscribed members?
