You may get 99% dielectric diagonal, but its price will be equivalent of what you paid for this scope (not worth it). But obviously it is recommended to take it off when imaging with camera Regular aluminized mirror reflects about 92% of light, so the image is darker which will not be that noticable for visual observation. I feel your complaints about hurting neck (exprienced that myself during long sessions with this scope), you might wanna get diagonal for more convenience of observing targets over the South side.īeware that adding additional mirror into optical train may affect its performance from two standpoints: Not yet, I have a little bit of the jargon stored back in my skull somewhere. So I may sound like I know what I am doing. My first job out of school was mechanical design of reflectance spectroscopy accessories- for the Perkin Elmer Lambda 90/900 and similar benchtop spectrophotometers. I bought a T-adapter, and then figured out I need to probably do this with the eyepiece unless I am taking snaps of a full moon. Plus I just want to look at the cool parts of the solar system. I want to try *some* photography, but I don't want to break the bank. I also have a Canon 5D 8MP full frame DSLR. 
I don't have a Barlow yet, and my neck hurts so I need to find a way to bend the optical path for the eyepiece, but I am not sure of the term to search for.
Oh, I bought a cheap laser diode collimator, too. I am not sure if that's to much magnification. I didn't get a full set of fancy eyepieces yet, but I have another Meade MA in 9mm FL that I bought here on the way, and because I desperately want to see Mars soon I got a Astro-Tech Paradigm ED in 3.2mm. So off to the classifieds here, based on a friend's advice, and Astronomics and Amazon. That only had a 25 or 26mm eyepiece in a 1.25" barrel, but already it's astounding! Or it is to me- remember, I am new. I was pretty sure I wanted something that was motorized to some degree and on the local Craigslist, I found a refurbished Meade 6" Schmidt Newtonian. I picked up a 4.5" Celestron 114 EQ from the transfer station (town dump) and after some refurbishment I saw some planets and the moon.
