hi Stef, in a way the salesman is right. astrophotos are taken in more ways than one.
in my opinion the vast majority of newbies that ask about astrophotography are not given all the info they need to know about the complexities involved.
if you just want to get a quick photo of a planet then sure you can stick a one shot camera to the eyepiece and there it is but if you are used to seeing nice crisp colour shots the experts have taken you will be sorely dissapointed.
when using a dob for astrophotography of the planets you will need a camera capable of taking video files, these need to be loaded on your computer and run through stacking software and processed which is another steep learning curve.
if using a mount such as the eq5 without good polar alignment and tracking, another learning curve, you are still confined to the process l have just described.
if you want to take a range of photos inc deep space objects min requirements are a mount preferably with go-to capability and good tracking ability and either a ccd camera or a dslr camera, example canon 400d.
along with this you will need some sort of imaging software for processing such as registax for video files or photoshop for dslr images.
please don't think l am being negative about anything l just think people need as much info as they can get before they start to try and capture those glossy pics they see in books, there is a lot of money to be spent along the way and it needs to be spent on the right things.
deceide what your interests are and get the hardware to suit.
