Now that there is a dob with tracking I was wondering if anyone had tried Astrophotography with the Orion XT8g?

I tried with the 12" inch skywatcher version. I had to collapse the tube by 2inch to reach focus.

I use to have a Meade 8" DOB without tracking and I was able to get some decent planetary shots just letting the planet drift through the view and then stack the images. I would assume if it tracks it would be the same as an Alt/Az mount and you would be limited to about 30 second exposures if you wanted to do deep sky. I would think you'd also have to figure out a way to add counter weights to offset the camera weight too.

I have an Orion XT8. I cannot reach focus using a DSLR for wide FOV images, even having bought the lowest profile focuser (aftermarket) on the market and adjusting the primary mirror. I can however reach focus using a 2x barlow, and a 5x barlow using my DMK cam even with a filter wheel using a DMK monocam. I can't remember if the stock focuser allows for this so sorry I can't help with this info. 2x barlows seem to be much more forgiving, but with the 5x powermate, I can just barely reach infocus...hence the buying of the low profile focuser. IIRC, i couldn't reach infocus enough using the powermate 5x with the stock focuser. I also can't remember if taking out the focus wheel in the image train, using a color cam, allows much more freedom. I'm guessing it does since the main problem is lack of infocus.

Bottom line, you can't really use a DSLR due to lack of infocus, but I have found ways to use a 2x barlow and a 5x powermate so worse case scenario is you may have to get the low profile caryford focuser such as the one Orion sells

Actually I was thinking of using a Neximage camera. Weight wouldn't be an issue.
FoxK, have you tried your SPC900NC or Quickcam 9000?

I have David. All cams shoild be about the same...its just a question of where the ccd or cmos is positoned in the cam with seems only to vary by a mm. If i were more mechanical, i'm sure i could jury rig a new case and move the ccd up close but my 900nc is too valuable lol

I assume someone has bought a Orion XT8g, right? Since it does tracking someone must have tried to take some pictures. Please chime in.
