Telescope Eyepiece
what size telescope eyepiece?
I have a an orion star blast 6 with a 750mm focal length,what would be the best power eyepiece for viewing planets?
I'd recommend something around 5mm, yielding 150x. This is enough magnification for normal viewing of the planets, yet not so high that it will often be rendered unusable by the atmospheric seeing. You can achieve this either with a 10mm eyepiece and a 2x Barlow, or with a long-eye-relief 5mm design, since a Plössl at that focal length will have uncomfortably short eye relief. I myself usually use a Tele Vue Radian 5mm, which is a very fine eyepiece. A couple of less expnsive alternatives are the Orion Stratus 5mm and the Orion Edge-On Planetary 5mm.
[Edit] Katekebo's answer of 300x is _theoretically_ correct, but not practical. The number of nights in the year you can actually use 300x with _any_ telescope is perhaps two or three. The rest of the time the image at 300x will be so blurry as to be totally useless. The realistic maximum magnification for a 6-inch aperture is more 150x to 200x, and I'm recommending 150x because I know from decades of observing that this will give fine views 99% of the time. If you're satisfied with the views at 150x after a while, you might consider adding a shorter focal length for those special nights that only come along a few times in the year, but start with 150x.
The images at 150x will seem small at first, but as your eye becomes trained, you will see a lot more. Making simple sketches of what you see will help train your eye to detect fine detail.

Telescope Eyepiece Kit
telescope eyepiece?
i have an old telescope that uses a .956" eyepiece
and i was going to get a new one ((i only have one that works with that telescope))
and i want to know what would be better
a 4mm Tasco or Celestron?
Pretty much all of those 4mm .965 eyepieces are junk, and usually produce too high a magnification. A 4mm eyepiece is of limited value in scopes longer than f/6, and too much power for those longer than f/8. and if it's marked "SR4", it's junk. Your highest power eyepiece should produce a magnification no more than 2x per millimeter of aperture.
There are some good to excellent old Japanese orthoscopic eyepieces in .965", but your best option, assuming this is a refractor, is probably to get a hybrid diagonal that will accept 1.25" eyepieces.
