Telescopes

my two set-ups

 

    For imaging, I have two set-ups.  I use the Celestron C9.25 SCT for planetary imaging and the Orion 100mm ED refractor, for deep-sky imaging.  And on those nights when conditions are not favorable for imaging, due to clouds, heat or an unsteady atmosphere, they're my eyes to the universe.

    The "nine," as I like to call it, is excellent in both the observing and planetary imaging categories but, due to it's weight and the mount I am currently using, (the CG-5) it doesn't track well enough in the deep-sky category.  

    For imaging purposes, the scope and whatever you have attached to it, should not exceed 2/3 (66%) of the mounts recommended load limit.  For the CG-5 which is rated for 30lbs, that puts the imaging rig weight at about 20lbs.  My 9.25" optical tube, fully loaded with guidescope, camera, etc., weighs in at 27lbs, which is under the load limit and fine for planetary imaging or observing, but too heavy for deep-sky imaging.

   

Orion 100mm ED refractor

 

 

 For deep-sky imaging,  I use the Orion 100mm ED refractor.  When fully loaded with the guidescope and the Canon DSLR camera, etc., this set-up only weighs about 20lbs, which is right on the imaging weight limit for the CG-5 mount.  With a precise polar alignment, the help of PHD guiding and the Orion Starshoot Autoguider, this imaging set-up has allowed me to try my hand at astro-photography.
