20 Most Recent Tasco Target/Varmint 6-24x42mm Rifle Scope Mil Dot Reticle - Page 8 Questions & Answers

Measure out 100yards and focus scope to that then replace ring to the 100 mark and fix

What is the calibre and velocity and target species as the zero distance could be 50-200 yards depending on what you are shooting most of my rifles are set to 100yards except for the nitro express Which is zeroed for 55 yrds and the 17 wildcat which is 200 yards It all depends on the range you will be shooting most

Here is a generic Tasco scope manual, since you did not provide the model number: http://www.tasco.com/products/manuals/TascoGenericRiflescope6LIMwebversion.pdf If you have the model number, the reference manual may be available here: http://www.tasco.com/pages/instruction-manuals/ Good luck.

Try eBay to compare.

The different eyepieces are to give different magnifications. This is worked out by dividing the focal length of the telescope, f = 900, by that of the EP. So the 25 mm Kellner (that is the type of optics in the EP) will give 900 / 25 = 36 times magnification. The erecting eyepiece is used for terrestrial viewing. Normally with an astro telescope everything is upside down as that does not matter when looking at a star. So when you want to look through someone's bedroom window you use this. A Barlow lens is an add-on magnifier. If you add this onto any EP (it normally fits between the EP and the scope) it will increase magnification x 3. There is a practical limit to what any scope will deliver, governed by its aperture (the size of the front lens) and for your scope this will be about x 120 magnification. Beyond that the image becomes too dim and fuzzy. This means that your 4 mm eyepiece ( x 225 magnification) won't be much use. It will be hard to find the object you are trying to observe, it will be hard to focus, and the image will wobble around. Nor is your barlow lens much use either I fear. You might consider another eyepiece around 18 mm to give a nice spread. A Plossl type is good. If you get serious about astronomy, I think you will immediately want a better scope after using the Tasco.

The Tasco web site does not list that model-- however it is a small reflector style telescope similar to this model-- http://www.tasco.com/products/manuals/Luminova40-076420Inst.pdf Use the above manual to help you assemble the scope.

For astronomical viewing this is unnecessary-- there is no up or down in space. :) For terrestrial viewing you can but an erecting diagonal which will make the image right side up.

This might be a problem with no palletable solution. Once the rubber reaches this stage it's pretty much of a write-off, sooooo this is what I might suggest;
4. Wrap the whole mess up in waxed paper and return it to Tasco.
2. Try spraying Armor All on the rubber and see what happens..
3. After smearing your hands with Crisco, pull all that goopey rubber off; spray paint what's left.
1. Call Tasco and ask for their advise, which will probably result in solution #4.

I've wandered over this planet 60 years and encountered this problem at least once or twice.
Made a decent living fixing alot of of things, but it took a while to understand that some problems are better dealt with by either handing it off to somebody else(rare) or just dropping it in the circular file(increasingly more common) It wasn't until recently that I realised that my motive in life(use it up, wear it out, pass it on or do without) should have resulted in me being born Almish. I think the rubber has returned to its native state, and only vulcanization will toughen it up again.

I favor #1,4,2, or 3 in no particular order. Good luck!

read the manual

All astronomical telescopes show the image upside down. For terrestrial use, you need a erect image prism.
