SOURCE: The adjustment knob was very hard to turn. Any way to lubricate?

I would be inclined to use a penatrative aerosol lubricant (like WD-40) in very sparse quantities. Squirt a little in using the WD40 smart straw applicator to direct the lube accurately and work the adjuster back and forth in a small section. Repeat this until you have freed up the adjustment from one end of its scope to the other. The focal adjustment is typically housed separately to the lenses and careful application of the lube should not affect them - avoid overusing the lube and have a mopup cloth under the spray zone to keep overspray/drips to an absolute minimum.

SOURCE: My Tasco 10x50 InFocus Binoculars

This is normal I'm afraid. "InFocus" is a brand name indicating that these are fixed focus. The name implies that they are magically always in focus, but actually means that they CAN'T be focussed. They have a fixed compromise focus setting that is OK but maybe not brilliant from far distance to fairly close, but actually only completely right at some point in between. If you want binoculars to use for much closer viewing than the compromise distance, you need to buy some with a focussing knob.

I have a makusutove 150 1800 telescope and I cant seem to get it to focus correctly - it seems as though the mirrors are focussing the light behind the viewing lens. I can get a focussed image if I hold...


You do not have enough BACK-FOCUS, you need an extension tube for the focuser like this one:

My EL 8.5 x 42 binoc's are approx 5 yrs old. The focus wheel has become very stiff. Is there a way to fix this myself?


No. It's best to have them repaired by Swarovski. There should be no cost involved other than postage.

I see double one over the other about 20 degrees


Up close to the eyepieces around the barrels are small screws that you can use to "collaminate" your binocs. The screws aren't meant to be accessed by the owner and most manufacturers cover them up with the material that surrounds the binocs. Of course the binocs in their current state are useless anyhow, so I wouldn't hesitate to peel up the material to look for the screws. If you do it carefully, you can reseat the material anyhow. Then once you locate the small screws, put the binocs on a stand or a table outside. Focus on something far away using one eye. Then using both eyes, you adjust the screw on the other eyepiece while looking through the binocs. Adjust until you get a single image. You can use loctite, or nail polish to "glue" the screw in the final position if it is really loose.

Out of focus


Assuming you are focussing correctly. When binoculars are out of collimation the most usual effect is double vision as the optical axis do not line up. The only thing you can do is to take them to a binocular repairer. The problem is the cost. Proper repair need the use of a device known as a collimator and it is a laborious task to do it properly. Your binoculars do not carry a high monetary value and a proper repair will cost more than a new binocular of similar specs. Porro prism binoculars mostly have the objective lenses set further apart than the eyepieces. This holds true except for reverse porro prisms which are the other way round. Roof prisms have both the front and rear lenses inline.
Make sure when you focus that the first eye you use to focus with is the one where the eyepiece does not have its own focus ring (dioptre). The dioptre adjustment is on either the left or the right depending on the brand. That eyepiece should be left alone until you have focused using the center ring. Then leave the center ring alone and focus the eyepiece that has the adjustment ring.

Focussing


All of Tasco's manuals are on this web site-
http://www.tasco.com/pages/instruction-manuals/

Put the eyepiece with the largest number written on it into the focuser-- do not use the 2x barlow if you have one. Practice focusing with this eyepiece during the day time on a distant object like a telephone pole or a building.

Focus Issues


Try tightening the grub screw that fastens the knob onto the shft that it turns.

Better still, buy a flexible extended focusser which makes focussing much easier. Check on eBay for "Meade flexible focus"

Double vision


The distance between the centers of the eyepieces of your binocular must be the same as the distance between your pupils. This distance is adjusted as follows: 1. Focus on a distant object. 2. Pivot the two halves of your binocular farther or closer apart until you can see a single unobstructed, circular field of view. Make sure to focus on a distant object when you do this because when you focus on a close object you always see two slightly overlapping circular fields. Your binocular may have a scale on the top, between the eyepieces, to help you remember this setting.

Internal cleaning


I don't know about disassembling binoculars. However have you tried drying them out, either in a "dry box" or by using silica crystals?
