which one?

[rowan46]

i have decided to get  an illuminated reticle eyepiece to hopefully get better accuracy on my  homemade push-to system and they have 2 in stock at the shop I will be going to tomorrow. 1 is a  second hand 12.5mm  celestron microguide  orthoscopic price 59.99 the other is a second hand meade 12mm  plossl  also valued at 59.99 but in better condition. I am told that both are fine optically so which one should I get?

Hi , I have not used these but the Celestron is an Ortho while the Meade is a three element, Modified Achromatic. I would think the Ortho will have the better optical performance.
