Blind Spot

[Dom_01]

I don't know if there is a technical term for this, as a result of my set up or if it's just me.

After positioning onto an object, when i look through the eye piece i get back areas, normally coming in from the side. It even happens when i am looking at the moon. When standing back from the scope you can see light coming out from the EP, but then if i put my eye up to the EP the view is limited.

I have to move my head around to improve what i can see instead of just my eye. I don't know if i am too close, too far, wrong angle. I am using Baader Hyperion (with rubber cup rolled up or down) Eps on a Explorer 200p

Hopefully i've explained myself enough for people to understand.

Hmmm sounds like it could be kidney beaning. Try moving your eye away from the eyepiece a tad.

I have a couple of Hyperion EP's and both require a 2" extender to get a good view, if your not using a extender, try loosing the EP in the focusor and sliding it out to check for focusing.

The Baaders are prone to kidney-beaning in the 200P. You have to get the eye position just right, at 90 degrees above the ep. I too have had the experience of a beam of moolight coming out of the ep when moving away, amazing isn't it? Sounds like a moon filter will help you. With hindsight the Celestron Excel LX's are better, I have gone down the more expensive Axiom LX route, perfectly satisfied with the views, and no kidney-beaning!

Thanks for the info.

When I purchased my new eyepieces it was between the Celestron Excel LX and Baader Hyperion. It looks like i made the wrong choice :S

i might buy the hyperions let me no

[rwilkey]

The Hyperions will work well in your cpc 9.25 faulksy.

bin there done that with this eypiece,it's very frustrating but

good news is it's you not the eyepiece,you have to overcome the idea of if i get closer i will see more!! there should be an eyebrow rest ( for want of a better name!! ) on top that twist's out a few mm that should help till you get used to it, also if you require glasses then wear them i found that helped also, all of a sudden one night you will realise you dont notice it anymore

It does sound like "kidney beaning" It was the first time i'd used the eyepieces, so it sounds like a case of getting used to them. I did notice being able to see my eye lashes, so it sounds like i'm pressing up against the eye piece.

IN a way it's good to know it's me and not the equipment.

Thank you people
