Just wondering which of these two EP some might suggest as a finder and wide field of view in my 10" f4.7, 14 f4.6 and 20" f5 scopes? More to the story but I just want a few opinions before I order. The 24 is on back order while the 27 is available. No biggie jumping from a 2 inch to a 1 1/4 for me. I'd like to pull the trigger this afternoon so if you have an opinion I'd like to hear it. Here is what I have Pentax XW 5mm, 7mm, 10mm, 14mm. (no longer available. When the stock runs out the XW line is suspended as the plant that made them was destroyed in the tsunami). These aren't going anywhere and thanks to Steve Fisher for getting me hooked in them at Lakeside last summer! Orion Stratus 13mm, 17mm, 21mm (acted as my finder) and I am currently selling these and will put them up on cloudy nights and they are up at The SLAS Classifieds. I may keep either the 13 or the 17 as a star party eyepiece. 5mm Hyperion. Probably going up for sale, we'll see. My daughter bought this for me 3 years ago so it has a soft spot with me. I'll probably keep it for that reason alone though it is duplicated by the Pentax. 32mm Q70 2" eyepiece. Not perfect but not too bad as a finder when I just want to see the real estate to find an object. Thus the purpose is to have something of good quality that provides a wide field while also serving as a finder. The 24 Pan works nice that way and wouldn't require a switch out on the EP holder when I move to put a Pentax in. Then again I am having to wear my eyeglasses while observing and I think the eye relief on the 27 Pan would be better while giving me an overall better wide field view. So I ask, do I go for the 24 or the 27? I have done the calculator and there isn't much difference between them. Thoughts? Sent from my iPad
