Dear All,
I bought my Powershot a710is in autumn 2006, which still appears to be going strong to this day. However, in the last year I have become more interested in astrophotography and use my a710is for afocal telscope work. With the help of CHDK I am now able to shoot, say, 50 continuous shots that I then stack to reveal incredibly clear and sharp images (for example, of the moon). However, this means in one night I may take around 500-1000 shots and from taking only 1000 a year between 2006-2008, I now take far more in one week. My concern is how long can the camera continue? Does anyone know? I must add, the camera appears as fit and healthy today (apart from the odd hot pixel) as it did when I first bought it.
The easy answer is to but a new powershot when I need to BUT it appears the new Powershots are less likely to be able to run CHDK software AND they no longer offer the ability to hold adaptors (ie to attach telephoto and wide angle lenses, as well attaching the camera to my telescope). With this in mind, I am tempted to buy a S/H powershot on ebay but am unsure which to go for. For example, I recently saw a a650is that woudl have been great but I can't work out if CHDK will work on it (as it appears to be firmware specific for this model and when I asked the seller what firmware version the camera had, he had no idea what I was talking about (and fair enough))!
Would anybody be able to advise what S/H Powershot camera is the best to buy that is most likely to run CHDK? I would really appreciate any help,
Thanks very much,
Nick
