Message: <blockquote data-quote="JohnJos" data-source="post: 1111619" data-attributes="member: 58536">Neil,You are correct...the adapter was hastily attached to the eyepiece so as to get a photo of the eagles.  It was so unexpected to see the two eagles at this location that I was very excited and wanted to photograph the birds quickly before they departed.  I needn't have worried because they stayed for quite some time, maybe 15 - 20 minutes, but did relocate further away after about 5 minutes or so.  I didn't notice the misalignment while I was taking the photos but  saw it after I downloaded the images and started looking at them.  They were also in rather poor focus.  So the fact that the camera lens was not parallel to the eyepiece lens may have  contributed to the CA.  I didn't know that could happen.  I will have to take greater care in positioning the adapter on the EP in the future.  I'm also working on modifying the adapter so that the installation is more foolproof.  I also have to work on a way to ensure perfect focus.  I can get good focus when looking directly through the eyepiece without the camera attached.  Then my photos are sharp.  But when I move the scope and have to refocus, I don't always remove the camera and refocus but try to do that through the camera display.  With my poor eyesight (I need reading glasses to see close-up), that usually results in a poorly focused image.  I'm going to try a sun-shade/loupe device to help assist with proper focus.  But I should just get in the habit of removing the camera, refocusing, reattaching the camera and then shooting the subject to get the best image possible.Thanks for your valuable input Neil.</blockquote>
