I just got the Orion SkyQuest XT10. I'm sure I'll have fun playing with the dobsonian mount it came with for quite a long time, but down the road I'm sure I'd like to try my hand at some astrophotography. What is the feasability of putting the OTA on an EQ mount? Where would be the best place to buy one? I've done a bit of googling and haven't found much, and what I did find was prohibitively expensive. I'm talking upwards ...

I apoligize if this question has been repeated (which I am sure for you veterans it has been), but prices vary from one extreme to the next, and from what I have been reading there seems to be a difference in quality. Money is somewhat an object in the household, but I would like to buy a fair quality piece. If you rather feel free to PM me with a response! I appreciate anyone's time for responding. Thanks.

Both telescopes performed well for deep-sky up at the Mt. Pinos astronomers star pary.

From my years of experience as an astronomer who has used a variety of telescopes of different types along with using very rare large apertures of 8-12 inches. I have found the 6 inch F/8 refracting telescope is the optimum design for lunar, planetary, and solar observing.
