E.T. Would Approve of Canon's New EOS 60Da DSLR Camera for Astronomy Enthusiasts



+ Add a Comment


Very few people actually use a DSLR for astro-photography. Think of how long the shutter has to stay open for even an off the shelf lens' or even for a 30k++ telescope?

With the lens being open that long, then the "in camera processing time" ones lucky to be able to get one hundred pics - so not quite up to true professional standards. Even with a battery pack - the camera is barely able to effectively keep up.

But there is one area where this one is above average... It is a dslr that also offers a swivel monitor, but... Even wtih the increased sensitivity and also ability to adapt to regular lighting - it's hardly worth that price. It should be offered at over three hundred less than that.

Most true photographers will most likely still want to stay with their Nikon F4's or even a Pentax K-01 - of which either would obtain considerably better results



Can it take pictures of Uranus?

Sorry had to....I'll be going now.



I thought CCD are the preferred sensor for astrophotography, because of the better night sensitivity.



Indeed they -CAN- be, but it also depends upon the individual's own preferences as well.

Often, astro photographers actually use purpose built cameras that are designed specifically with no/low light in mind and excel at contrast, even to the point that the camera itself is monochrome.

The methodology for getting color imagery is of course stacked exposures, with multiple filters which are commonly Red, Green, Blue, and Hydrogen-Alpha. There are of course many color camera systems as well, and each have their own benefits and detriments depending upon what is being photographed in the sky.

Large and near-by things, planets for instance, typically don't take much in the way of a camera, but depend more heavily on conditions to get good details.

Deep sky objects, faint nebulae, and small or very distant galaxies for instance typically rely heavily on the conditions as well of course, but sometimes squeezing details out of the "faint fuzzies" can be grueling and trying to say the least, so any edge that can be provided by a piece of equipment is often welcomed and a camera who's sole function is capturing such objects is often preferable to one that's somewhat of a re-packaged version of a preexisting camera body with a few tweaks that the end user could have done.



I'm sure it's a fine DSLR for astro-photography, but you can get perfectly comparable, if not superior, DSLR's for a fraction of the price and simply swap out their standard Hydrogen-Alpha (Ha) filter that typically blocks most of that part of the spectrum for one that lets 99% through, and they are quite cheap and easy to install.

Best of all, there are actually settings options/changes that can be made so that the conventional DSLR with the replaced filter can still perform perfectly as normal in day-light, while still performing exceptionally in astro-photography.



on these canon's it's typically more than just a filter swap that makes them specialized for astral photography...



Indeed, there are often "bells" or even "whistles" added to them ⌐_⌐

Even the 'sales pitch' clearly emphasizes the pre-installed Hydrogen Alpha filter which allows high transmission of that end of the spectrum, which is the key caveat with any DSLR camera, as the other typical emission band is Oxygen-3, and O3 is typically not problematic with conventional capture methods.

As such, the camera, while I'm sure is very nice and feature rich, is not necessitating its price for what is clearly a very minimal gain over what can be done through alternative methods.
