Well I have put them on a tripod looked at a post about 50 metres away used the diopter on the right to defocus that held my head back a couple of inches could clearly see two images with slight adjustment to the collimation screws I now have them on top of each other.

Just need a clearish night now to do a star test but once I had set the diopter back I have the clearest image I have had out of them so crossed fingers it has worked.

@Peter Drew thank you I swapped the barrels over before tweaking and it made it a lot easier as the images where not that far apart.

ack, sounds like seller knew there was a problem and just wanted shot of them  Ebay/paypal may still act in your favour tho if the ad says they are correctly aligned, but if there's signs you've tried to adjust that won't help of course.

When I went to adjust them there was some glue showing and when I pulled back the rubber has split so I have no chance.

Then return them as they were not accurately described. Raise a PayPal claim and get your money back. I did that with a pair of £20 binoculars which were described as optically perfect but had fungus on the prisms. PayPal refunded my money including postage. Don’t put up with it Paul, not worth the hassle.

Advertisement says no returns so I dont think I can do anything and since I have tried to adjust them he can say its my fault.

Are they new? In which case I'd return them.

If not then I'd adjust the right side if it'll bring the images into alignment and not make the exit pupil go further out to the edge. Could be that a prism is out of place in its seat if they've had a bump and while you might be able to twiddle the screws and get them usable it'll maybe shift again later and need this all doing over, or worse, chip and become useless.

Can you you tell me which screws adjust what and do I adjust just one screw on the right or both thanks. They are second hand bought sold as seen from the Bay the description said optics perfect just needed a clean as where a bit dusty, when they came they where dusty I blew all the dust of and cleaned them they looked great until I tried them.

I assume these are porro, were they from Lidl? 

Tweaking the alignment at home is a tedious process and needs a lot of patience and very small adjustments to the prisms unless you've got the right gear that the pro's have. Did you tweak both sides or just on one side of the binocular?

Holding the bino a couple feet away how to the exit pupils loon in the eyepieces, central or offset?

Daytime you can adjust and get them close but testing against the stars will give you a more definitive answer as you've found. I've done this on several binos now and on clear nights I've been in an out several times making small tweaks until I have them right. I find it easier to go in and adjust under lights as it's easier to see the screw rather than fumble in the dark and drop the jewellers screwdriver and try to find it, or worse the tiny adjuster grub screw. Best to work on one side only at a time (I start with the most offset exit pupil), else it can be like having 2 cats on leads and trying to take them for a walk  but be aware that if a large amount of adjustment is being made you may have started on the wrong side and the exit pupil may be well off centre.

I have also used a light indoors to help get them closer than using a roofline but getting sufficient distance makes that harder. I use the reflection of the light off the glass front door panel but even so that's only around 10 meters but I've found it works for me, guess because I've done it several times. Another option, if you can tripod mount them, use an object with a distinct Y or cross pattern, a distant bare branch or TV aerial as that'll give a much more defined view of the alignment than a roof.

Also when you are checking, don't forget that your eye will quickly accommodate any error in daylight as there's plenty of background for the brain to merge. To get around this use a dark card over one objective and while looking through the bino, remove it and note the first instant view. Repeat a few times to confirm and adjust then redo. Best to do this when your eyes aren't too tired as well.

Once done you may well find that someone else will find the same issue you were seeing, since you won't have collimated the 2 sides, merely adjusted the alignment to suit your specific IPD.

hope that helps.

I adjusted both sides the left needed going up so much I thought it would be better to bring the right down a bit.  Exit pupils in both are off the left a lot smaller but up and to the right  the right lens is way off up to the right quite away.

You do have some bad luck Paul! I assume these were bought secondhand and can’t be returned? 

Yes Stu and yes I must be cursed or something.

Bought a pair of Bresser 10 x 50 long eye relief binoculars, when they came they did not focus sharply.

Went online said check horizontal with a roof of a house and gave instructions as to what to do if they did not match. 

They did not while the right lens had the roof top horizontal in the FOV the left was down following the online instructions found collimation screws adjusted and both where level.

Took them out last night trying to glimpse Comet Neowise with breaks in the cloud looked at a star I now have two images one on top of the other I have tried online instructions but it is getting me nowhere is this just a case of bin them and move on.

All input welcome

Paul 

Got these last night with my phone as where the comet is I cannot see it from my observing position.

It's frustrating when things don't go right and I know from experience.

You need to go through the same steps every time.

Level the tripod.

Add the mount.

Polar align 

Add weights and Scope

Check polar alignment.

Choose either 2 or 3 star alignment after putting in your co ordinate's and time and date.

Go to your first star it won't be in fov use your finderscope, telrad or red dot finder to centre it now check your eyepiece centre it in that pressing right and up last.

Go to second star this should be in fov or very near do same as before.

Now either go to a object or to 3rd star, if you go to a object and it is slightly off press ESC once the press again but hold it in the object you have gone to will now be displayed and it will say centre object do the same as the alignment stars and finish with right and up keys.

Goto your next object this should now be in the centre of the fov.

Keep calm and once you have done these steps a few times it will become second nature and you can enjoy your sessions.

I had exactly same problem as you I can now do a session just on double stars and hit every one.

Good luck.

I have a couple of new books read through double stars mostly 😃

Nice one Wookie, glad it's all together now and ready for clear skies.

Thank you Mark could not of done it without your skill with a lathe.

I think it looks great. I'd be happy to have that set up stood in my garden for everyone to see. You've done really well to have created that from the parts you were (mis)sold. 

Thank you very much really appreciate that,  it has been a Labour of love with help from this marvelous forum.

A very kind SGL`er made me a proper centre bolt and I have tarted up the tripod and bits what do people think.

A Warm Welcome to SGL

I thought I had not seen any posts by you Shane great to see you back .

Wear a eye patch on your non viewing eye that way you can leave both eye's open much more relaxed viewing.

Oh - you want us to spend your money 😁

Well, you have a very capable 150mm Newt so what are your expectations from buying a refractor ?
 

To get brighter views with more resolution you will need a large refractor - perhaps as a minimum the Skywatcher ED120 ? BUT it will need a suitable mount so the price rapidly climbs.

A much cheaper option to improve on your 150mm Newt would be a 10” Dob.

 

 

My first Scope was a skywatcher 150p and that is the only one I have ever seen 6 star's in the trapezium, I never saw it in my 8inch or with both of my refractors, saying that when I did see them I had a pristine night I've not had one that good since with the lamp outside my viewing position 😥

The 150 is a very capable scope.

My Meade 127mm had a terrible focuser on it a friend gave me a Skywatcher dual focuser that needed tweaking. I also needed a an adaptor to make it fit.

I contacted Mark at Moonraker He said send the old and new focusers and plenty of measurements and diagrams and he would see what he could do.

He rang me about how much infocus I had to make sure the skywatcher would work properly said the Meade focuser was it out of a lucky bag  and said he would look at the skywatcher focuser.

6 weeks later rang me all finished with a price he had made the adaptor araldited the focuser in the adaptor and told me he had tweaked the focuser told me there was a ballbearing missing and a couple of small grub screws.

Sent it back to me I put it on and the view was terrible took the whole thing to Peter Drew brilliant bloke he looked through it and said I know exactly whats wrong the two pieces of glass at the front had been swapped around.

He took it apart and they where swapped them did a star test on a artificial star and it was bob on,  I brought it home checked collimation and it was collimated to perfection I was lucky I guess. 

The biggest scope I've looked through is a 22" at M51 and what a sight it was. I had a lovely 8" reflector which I should never of parted with it was very good at getting fainter objects.

I only ever used it at meets so 2/3  times a year good for deep sky.

I have two refractors a Tal 100rs and s Meade 127 5"  these you can get out even if the sky not that clever these punch through. Double stars, multiple stars and cluster's even from light polluted sky's is why I have them plus planets look like marbles and stars look pin sharp.

This what I have to put up with complained to the council they put a shield on this is the result , not worth a carrot

Well I balked at the price for a handle with delivery over £23 so had a quick look on a other site went for a mild steel flat bar 8mm thick 30mm wide 300mm long.

It came today £7.99 but it was much heavier than anticipated drilled holes balance was way out but I was really concerned about the weight capacity of the EQ5 mount.

My son came over social distance was in place he had a look then said you have another dovetail don't you, so I went and found it he measured drilled one hole spaced it so my hand will fit under it and bobs your uncle.

Here is the result.

Stay safe

Thanks Paul. I've only ever seen it in my 10" Dob. I'm not sure on your 5". I'm only using 133x mag to see it. How well does your 5" resolve the stars in M13?

In good seeing they have resolved just as good as I have seen them in my 8" reflector which I wish I had kept hold of.
