The manual that accompanies the Meade ETX 70 says something to the effect "this telescope is not suitable for long exposure photography"
well some time ago, I said they only make the scope, what would they know, and set myself the target of imaging 100 (mainly deep space) objects with the ETX 70.
I am about half way there so I have collected my images at
http://www.freewebs.com/seeker372011/
The verdict: well you be the judge...sure the images are not beautiful, say when I compare with my own images with an ED80/canon 300D..but in general I feel they are recognisable, occasionally half way decent..
but I sure had fun collecting them!..some were very hard work though!
but remember the ETX70 now is available on eBay for under $150 US!
My own favourite is the image of the Swan nebula taken from my backyard on a night of exceptional seeing
