MrBoBoTom: Hi. What about people who wear glasses? I have very poor eye sight without my spectacles on. Do any contraptions exist that allow me to wear my glasses while viewing an eye piece?

naperdood: Great video. Thanks for the tips!

it means no a lot to me lol this information, but what would I need to look at the moon in more detail ? also to see Saturn if possible ? do I need an eyepiece or something else ? cheers

Destiny Price: the field reducer is used on SC telescopes for astrophotagraphy. the f number on my scope is F10 using a reducer gives me a wider flatter field. smaller? there are 3 sizes but one is not really used the .9 inch the most common is the 1.25 but the large 2 inch is good as well. but if you are talking about the size of the focal lenghts the range from 3mm to 50mm and everywhere inbetween. best thing is to get a lens kit like the Meade 4000 lens kit

Destiny Price: no. the way you look at it is apature of the scope the larger the apature the more light it pulls in each scope has a useful limit of magnification. what you can do is double it with a barlow but as you go up the darker the image gets

daringwrinchester: by solar im guessing the sun? well you can use solar filters that are placed in the front of the telescopes. Dont ONLY get a solar eypiece, get the filter that fits infront of your telescope. 

alexander hernandez: my came with a 4mm

samweirdo: I'm pretty sure this guy is a future me.

Dhaval Malte: Even I have the same telescope, still trying to understand how to use it.

Wild River Tom: I have done that. You can increase the size & quality of your eyepieces for junk scopes, and it does improve them, but ultimately all you are doing is making a suck scope just suck less ;-)
