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
jellepieters: when you get really high ....
Jules. Verne.: @shantikiran1000 This is Astro-Photographer Jules V. shantikiran1000 you
will NEVER get 360x, The maximum your Telescope will ever get is 60x per
inch of Aperture or your 50mm. Achromatic Objective is 2inches(50mm.)
2inchesx 60x=120x ultimate Maximum Magnification NOT 360x!!
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 ;-)
Vibol Lee: one of the things i learned today! (length of the focal length of the
telescope) ÷ ( length of the focal length of the eyepiece) =
alexander hernandez: my came with a 4mm
monkeyboy4746: @Vijster1 They are used with refractors to allow a "right-side up" image
for terrestrial viewing.
windinhishair10: @natethegreat821 so you can use your scope to see it up close lol
AkiThePirate: @SoumyaSumitra You should be able to see Jupiter quite nicely. It's in the
south-east(Northern hemisphere) at about 2am.
Mark Walker: This is excellent information for a beginner like me. Thanks
Big Johnson: Why is the camera so far away..... wtf
Dhaval Malte: Even I have the same telescope, still trying to understand how to use it.
rocket9244: DAMN Ads!!!
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.
mangudiaforce: 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
Driver599: I know you did not mention variable barlow lens but are the 2-3 variable
any good and would you recomend them or are they low quality.
Cheap Boy's Air Rifles: 9 people don't have a telescope
Zenziba: wtf u gonna do with 55mm?
Nighthawke70: I can see his eyepieces are Celestrons. I own a six pack of their brand
including a set of filters in a metal case. Very nice and an excellent
investment. Often times you'll run into cheap eyepieces with most telescope
outfits outside of the thousand dollar range reflectors or large SCT's
jamesbondaygee: The Volt Sucks! It's just a gas car!
Vijster1: thanks for the stuff about the barlow lens, but what about the thing that
is called the erecting eyepice????
atlasdaddy: Thank you for the info. Very helpful for purchasing my next eyepiece.
IAMMATSUDA: @Zenziba95 spy on neighbours :)
shantikiran1000: hey i have a 360x50 mm telescope.. how to use it to see the solar objects?
Ivan Bok: @chuananrock, edu-science telescopes are no more than just toys that
advertise based on magnification and not aperture. I used to have one when
I was 9. Apparently, the image quality is bad and the tripod caused the
stars to move away as soon as you center it.
ddacanay09: things get dimmer and less clear as the magnification goes up! so its
better to use a lower magnification in viewing or looking an object in the
mangudiaforce: 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
fordpwrXR8: @SuperGKproductions get a star map....just look for Jupiter ...you can not
The1skinsfan: What would be the purpose of lowering you're magnification, also are there
any smaller lenses aviable than the one that came with my telescope.
gibs9105343: could i make a kiddie telescope stronger by adding a stronger lense ????
samweirdo: I'm pretty sure this guy is a future me.
paulosham1: Just what I was looking for, thanks.
MrFlyingscotsman1: freaking Adversiblalbla!
Soumya Sumitra Behera: How far can i see with a FL 300mm of Objective and FL 15mm Plossl eyepiece
jamesbondaygee: Nice, but doesn't really explain the inner workings of these lenses. We
need diagrams to illustrate these points.
vallev99: i have a telescope but i cant see a thing through it!!! how do i see
Pablo León Colombo: Very helpful, thank you.
Universound57: @Zenziba95 lower magnification ...26mm - 55mm are great for viewing deep
sky objects such as galaxies and nebula, as well as a great somewhat
panoramic view of stars. very amazing to see, i recommend the televue
panotopic 35 mm
