Q. Which should I buy? ...it is between the Canon A4000 IS or A2600?
Technical Benefit Differences of A4000 IS the A2600 lacks I see:
1. More zoom range (8x vs.5x)
2. Optical Image Stabilization/Intelligent Image Stabilization
3. Better Macro Capability (1 cm vs. 3 cm)
Technical Benefit Differences of A2600 the A4000 lacks I see:
1. Longer Battery Life (ECO Mode -- up to 30% more pictures per battery charge)
2. Wider Aperture (f/2.8 vs. f/3.0)
3. Lower Light Exposure Sensitivity in Low Light Mode only (ISO 6400 vs. ISO 1600)
4. Digital Image Stabilization -- Yes, an added feature the A4000 lacks; but greatly inferior to Optical Image Stabilization/Intelligent Image Stabilization
The physical size, dimensions, and weight differences, are very minor to me; both relatively small. Other than these differences above, they are technically the same compact camera. The A2600 is this years (2013) new Canon compact model release -- highest model of the newest of the A-series. The A4000 IS is last years (2012) Canon compact model release -- overall highest still for this years A-series lineup.
This is just an opinion question, but if you could justify your answers as to why YOU would pick one over the other with reason, that would be great! I am stumped. I am torn between these two. Thanks!
Let me add...
If you ask what kind of pictures I generally take, I take all kinds like landscapes, portraits, close-ups, night scenes, action, etc.. Yes, a general use camera.

Answer
No need to enumerate what you shoot. It is expected for all cameras to do them all anyway.
Judging from those spec differences, I'd go for the A2600. Battery life would be a huge issue and it would be nice to see Canon actually address the shortness of it once and for all. Wider apertures allow for longer shooting pleasure after the sun has gone down. It also helps blur backgrounds more easily for closeup portraits.
Although I personally avoid going higher than ISO 1600, it's good to know there's more in case I really need it. Image stabilization would be great though for making razor sharp shots but it's not really that important as I am confident my hands can still hold on steadily.

Atrophotography which camera to use?
Q. I have a orion xx12 telescope and i am not really ready for the photography side of astronomy yet BUT my grandfather is absolutely set on buying me a camera for my scope so i have agreed to getting 1 but which kind is better a digital or a film camera and also which make is the best for this job
In the catalog i got with the telescope has a bracket that is for the orion xx12 anyway i should really ask this question in about 5 years time because i only had the scope for 2 months or so and i (would rather have a shed for my scope) just need a camera for now really because my granddad is bugging me that i should be able to photograph the likes of saturn and such so just to experiment with what could i get for 250pounds that would be a good starter.

Answer
First off, the XX12 is not suitable for astrophotography. You need a telescope that can be polar aligned and tracks. The XX12 does neither, since it is a altitude-azimuth mount, instead of a equatorial type mount and has no drive motors.
You'll be wanting something more like this -

You can use a web camera for doing simple lunar and planetary work. Then you can capture a few seconds worth of video and then stack the frames up to get a picture.

For alt-az and deep space work, you can only expect to get no more than 30 seconds of shutter time before image rotation sets in -

But if you want to look at cameras, you need to figure out a couple things -
Do you want to use an off shelf DSLR camera? That you can use during the day as well as night?
Or, a dedicated camera that is for astrophography only? And do you want the camera to do color or monochrome?
A DSLR is a a nice choice for starting out, since you can dual purpose it. The problems with it are that you need to be able to control the shutter for minutes (most only go to 30 seconds) and it needs to have low electronic noise. The preferred DSLR's to use are from Canon. A dedicated DSLR for astrophotography is Canon's 60Da (about $1660), but they do make other cameras that are cheaper.

They have a wide amount of support from 3rd party vendors for camera and shutter control. One of the easiest to use is Nebulosity -

For a dedicated astro camera, they come to two flavors, color and monochrome. Color is the easiest, since it does it all in one shot. But is suffers in resolution - the amount of detail the camera can see. Since one 1/3rd of the ccd element is covered by either a red, green or blue filter (your eye works along the same lines).
Monochrome cameras have better resolution, but you need to take images in red, green and blue filters and then combine them for color. Which can be very time consuming and has a high learning curve for getting it right.
