DetailsThe TPO 6" f/4 Imaging Newtonian OTA isn't just an excellent imaging telescope, it's a portable and affordable excellent imaging scope. Like all TPO Imaging Newtonian's, the 6" model is an ideal scope for anyone looking to take their first steps from visual astronomy into astro-imaging as a hobby. TPO's 6" F/4 Imaging Newtonian operates at a high level and is lightweight enough to be a viable choice with almost any equatorial mount, meaning that you have a wide array of options in terms of mounting and tripod selection. The optics on all TPO Imaging Newtonians consist of a parabolic primary mirror and an elliptical secondary, or diagonal. The mirrors are made from B270 white water optical crown glass, which is more thermally stable than glass traditionally used on other reflectors. A 91% aluminum coating is applied, and then over-coated with a layer of quartz for the ultimate in durability. The primary mirror cell is very sturdy, and has six collimation knobs that can be adjusted by hand with a push or pull of the knob. Collimation is made even easier due to the center spot marked on the primary mirror. The diagonal mirror is held in place with a thin four-vane spider.

Product QuestionsTPO 6" f/4 Imaging Newtonian OTA... Can I use this as wide field visual scope on my 15lb capacity tripod mount ? Thanks, Karen...Question by: Karen on Jun 16, 2014 9:07:26 AMHello Karen,
The total weight of this telescope is 13 pounds so if you're just using this for visual use. You should be just fine.
Since this is a fast optical system, a coma corrector will be necessary to get rid of the coma that this telescope will introduce. I would say that something like the MPCC from Baader would be a good choice.Answer by: Roderick (Admin) on Jun 17, 2014 1:20:16 PMQuestion by: Richard Lighthill on Nov 16, 2016 5:04:00 PMQuestion by: Oscar on Jul 8, 2014 6:33:27 AMQuestion by: Bilal on Jul 1, 2014 10:28:00 AMThe included focuser with this scope has been improved with the addition of a steel runner that stiffens the focuser tube and prevents it from tilting under heavier loads. As long as the tension screw under the focuser shaft is tightened adequately, the focuser will be able to carry a 7D and an appropriate coma corrector such as an MPCC. It won't be stable for a camera too much heavier, though, and for a camera in the 3-5 lb range like some CCD cameras with filter wheels, I would recommend considering an upgrade to a heavier focuser.Answer by: Chris (Admin) on Jul 3, 2014 6:58:40 AMHi, Can you please check and confirm whether the Orion AccuFocus mounting plate works with this TPO 6" F/4? Thanks.
