Just out of curiosity, which is your preferred eye at the eyepiece? Does it make a difference?

I guess it depends on which is the dominant eye. Mine seems to be the right eye but I can't determine why. Both eyes see the same way but automatically I elect for the right. Just feels more comfortable.

I wonder if it depends on right or left handedness? I am left handed.

I think most people naturally use their dominant eye.  One way of determining it is to make a circle with your fingers and hold your hand out at arms length.  Hold up the circle and look at something through through the circle, then close one eye and then the other.  You will see which is dominant.

It makes a difference for me, I use the right eye, as it's my dominant eye.

I guess it depends which eye is better rather than handedness/dominance.

My right eye is definitely better than my left.

My viewing eye is my right but due to a massive number of floaters I have trained myself to use my left which is floater free  It ddn't take long

I am right eye dominant and I use my right eye for deep sky, it sees more on extended objects.  My left eye has less astigmatism and I use it to split double stars.  I usually use both eyes, moving back and forth, when I split doubles but only my left can split the closest ones.  With planets I usually spend equal time with each eye.

 

I have un-driven dobs and I use "move then let drift then move" for tracking.  I cannot do the "move" part with my left eye, it must be my right eye.

I use my left eye, which is my dominant eye. I have tried using my right eye but I just cannot seem to get comfortable with using that eye.

On very dim Deep Sky targets, my R provides a less noisy rendering; my L is noisy but more sensitive. On monoscopes I therefore use one and then the other to tease as much information out of the presentation as possible. But nearly all my scopes are true binoscopic (two identical co-aligned telescopes). The two-eyed view enjoys the best of both --- and reveals much more than either alone... better brightness, contrast, and resolution!

Feels more natural to use the left, but I vary now and then, to let the left rest a bit. Or maybe more let the right rest, keeping it lightly closed when observing, bringing some tension.

I use my dominant, right eye. But I do switch over to the other one when I feel the right one is getting strained or tired. All I need to do is adjust the focus. I actually find that my left eye gives me slightly better viewing but its hard to get into the habit of using the left one predominantly.

I view with my right eye.  I am left handed, but right eye dominant.  Curiously, I've been able to discern that my left eye has a slightly longer focal length than my right eye.  I don't notice it throughout the day, but if I sit there and compare left to right, I can see it.  I wish I could use this to my advantage at the eyepiece, but viewing with my left eye just doesn't work.  And it's such a small difference anyway it wouldn't really make a difference.

This topic comes up occasionally.  I'm one of those odd people who is right-handed but left-eye dominant.  I always use my left eye at the telescope, my right eye just doesn't feel right.  A few years ago, I started big binocular observing.  Some nights, I just can't merge the image - I think my right eye tends to drift.  Other nights, I'm good to go.  Just one of those things, I guess.

Hi all, I am right eye dominant but my left eye has a very slightly better image. My left is very susceptible to bright light and is often in squint reflex in bright sunshine. So although I find using my right easier, I practice using my left as much as possible as its acuity is incrementibly better.

Clear skies & Good seeing

Another oddball here!  My left eye is dominant, but I'm right handed.  Which eye gives the best image varies from time to time.  I view with my right eye for mono, as it seems awkward to use the left.  That's probably because I've always used the right eye for aiming firearms, except when I use both eyes.

 

This all must have something to do with why I really prefer binoculars for all astro use as well as terrestrial.

Interesting! I remember reading an article about pro baseball players that had an above average hitting percentage. Turns out most of them were left eye dominant but righted batters.

To complicate things, I'm right handed but both left eyed and left footed! Wonder how that did happen wink.gif

I am right handed and left eye dominant.  They say that right handed-right eyed is about 2.5x more common than right handed-left eyed.  

 

Cross dominance is not a good thing when shooting a rifle.

I am left-eye dominant but right handed. I have used my left eye for almost 60 years for astronomical viewing.

 

My left eye is less near-sighted but far more stigmatic than my right.

 

Close double stars now require my right eye, which sees clearly without corrective lenses.

 

I see a ton of detail for example in globular clusters with my left eye; my right eye cannot discern as much detail, even though it's capable of better resolution and clarity - I believe this is because my brain has been trained over the decades to see all the details with my left eye, but really never with my right.

I was born left-handed but the nuns forced me to write right at a very early age, by tying a (small/tiny) red boxing glove on my left hand for a couple of weeks... which turned out to be a blessing. I became rather profoundly ambidextrous. I of course took offense at first, but then noticed the advantages and actually practiced doing everything switch-hitting. It was fascinating. Scissors, hammer, saw, eating, shooting, writing, drawing, hitting, pitching, arm-twisting. "Comes in handy" Everyone else started to look lopsided to me, like availing only half their capability. My indoctrination occurred so early that I think it even affected my brain. Most friends were either good at this or good at that. Although I liked creativity, I also aced the English SAT (and two years early). Maybe all kids should be forced to wear red boxing gloves on their less dominant hand. Throw in a wee bit of genetic engineering and we can goose-step to our earned destiny!    Tom

I am cross eye dominant (right handed, left eye dominant).  Coincidentally I tried viewing Jupiter the other day with my right eye. I had been veiwing with my left eye in my FC100DL and had identified the GRS, two barges and could count anout nine bands. Switching to my right, and I could barely see anything. A white disc, two blurry equatorial bands. That was it. I tried refocusing, but that wasn't the problem. My eyes both have the same degree of nearsightedness (-11).  No, I just couldn't see as much. I tried to relax my eye and take in the view and after a few moments the GRS came into view and I started picking up a few more bands but it was nothing like the vivid view in my left eye, so I switched back. 

 

Immediately upon doing so, the view in my left eye was terrible.  But after a few moments it started coming back and after a few minutes I could see all the details again. 

 

It was a weird experience and I think I will stick with my left eye. I've never been fond of binoculars and I don't like using a bino viewer, probably because I have trained my brain to use my left eye so well.  

 

I was born left-handed but the nuns forced me to write right at a very early age, by tying a (small/tiny) red boxing glove on my left hand for a couple of weeks... which turned out to be a blessing.

Same thing happened to me but at a younger age, around two when I was first learning to draw pictures and it was a Catholic grandmother who made me use my right hand.

 

But I don't have such a positive outlook on it as you. I feel like it left me a bit dyslexic and confused. I have a lot of trouble telling left from right. Frequently when driving to new places, I turn the wrong direction and if you tell me to turn left (or right), I have to think about which way that is for a few seconds before I can do it Can I prove my problems with dyslexia stem from being forced to use my right hand?  No, but I've always felt that was the cause.

 

My daughter is left handed and no one forced her to use her right hand. Unlike me she can't do much with her off hand. 

 

Although I am semi-ambidextrous and can do a lot of things with either hand, my precision with my right hand is far superior.

While I can shoot with either hand, I think I would be a lot better at it if my dominant hand and eye matched.

 

In college I fenced competitively and while I was competent fencing left handed, I was never as good left handed as right handed.  But it was fun to be able to pick up a foil in each hand and fend off two opponenents at once during sparring practice. I was the only one on my team that could fence with their off  hand.  I wasn't half bad with my right hand and once beat Olympic fencer Bob Marx in a tournament bout. And though I could fence competently with my left hand, I wasn't winning any competitions with my left hand.

 

My fencing days are long past, and I'm not sure the ability to hammer a nail or turn a wrench/screw driver with either hand is worth the confusion and dyslexia. Although, it does come in handy when working in tight spaces.

No problem, support the rifle with your chest and aim / fire straight down the barrel  Just make sure you have a good grip and a good recoil pad, lol

My right eye is 20/15

left eye is 20/20

 

I use the right.  It’s the dominant eye and feel like I can focus better.
