An odd number of mirrors will give a wrong way round image or lateral invertion. We need an even number of mirrors in a telescope. Great video.

Thanks. Sharing is caring .Dear friend ,ARE YOU SAVED ? IF YOU DIED TONIGHT WILL YOU GO TO HEAVEN OR HELL? The Bible says: God is holy and heaven is holy which means perfect. God can never let anybody or anything imperfect or sinful enter heaven. Have you ever lied once? Stolen once? Hated once? The answer is yes .This makes you a liar, a thief and a murderer according to God. So if you were to die this night you will go to hell because you have sinned and the punishment of sin is death. The excellent news is that GOD wants you in heaven with Him. But as a just GOD, He has to punish your sins. He has provided a way to save you .There is someone perfect who was willing to take your punishment, mine and the one of the whole world. John 3:16 says: “For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life.” So Christ died on the cross for our sins. WHAT CAN YOU DO TO BE SAVED? 1- Admit you are a sinner. 2-Be willing to turn from your sins and turn to God (repent). 3-Believe that Jesus died for you, was buried and rose from the dead ,according to the scriptures. Romans 10:9 say: “that if you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved.” 4-Now through prayer, invite Jesus into your life to become your personal savior. 5- Pray this prayer of salvation :( Say it aloud) Dear God, I come to you in the name of Jesus. I admit I am a sinner. I thank you that you loved me so much to send Your Son to die in my place. I believe in my heart that Jesus Christ died on the cross and shed His blood for my sins, was buried and rose again the third day. I am willing to turn from my sins .I ask you to forgive me Father. I now invite you Lord Jesus, to come into my heart and life as my personal Lord and Savior. Amen. NOW YOU ARE SAVED OR BORN AGAIN WHAT DO YOU DO AFTER? 1-Read your Bible everyday to get to know Christ better. 2-Talk to God in prayer everyday. 3-Be baptized, worship, fellowship and serve with other Christians in a good bibelbelieving church. 4-Tell others about Jesus. NB: Congratulations .You have just made the most important decision of your life by accepting Jesus.

I got Celestron 50AZ and I cant see anything except moon. what can I do to upgrade the existing telescope.

I'm bored with your comments.

wouldn't using binoculars be highly impractical. The slightest movement would make it near impossible to focus on an object other than the moon. Is there something im not aware of?

TJ: Andromeda, as with any galaxy will always look fuzzy. The only way to get color and detail is through long exposure astrophotography. Venus is so bright that you will want to see it against a bright sky to actually reduce the contrast. And you won't be able to see Saturn's rings, but you will be able to see it has an oblate shape and its orangish hue. Neptune is hard to find, I agree. I own a telescope, but I always take my binoculars with me when I go out observing or for astrophotography.

HKA I got to see things but not what you described the andromeda was a fuzzy fuzzy spot but I enjoyed finding stars and planets. Barely saw Neptune
HKA (1 year ago)
James - you might be surprised at what you can see with binoculars. For instance, a 7x50 or 8x56 would easily show Jupiter's Galilean moons and spherical shape (but not detail), Saturn's yellow hue and oblate shape, and (barely) that Venus has phases. Several open clusters are visible as well. Most binoculars will come with tripod mounting capability; you'll need to purchase an inexpensive adapter. Look for ones with long eye relief.

Binocular magnification is low shaking is not a big probem at low power

I would have to disagree. This is if you are rich, and these people seem to have contempt for anything less than a 3 inch aperture, considering it a waste of time. For bright deep space objects and planets a mere 60mm refractor is excellent for the beginner, and is also nicely portable for carrying to dark locations. I don't even have very good visibility where I view from, but usually get good views, for example Titan, the largest moon of Saturn is clearly visible. And magnification over resolution is sometimes preferable for satisfyingly large, but a little fuzzy, views of planets. For the small telescope user wanting higher magnification I would recommend instead of getting a cheap high power eyepiece, get a second Barlow lens and stack them.

I don't know, there are so many good reflectors on Dobsonian mounts that are quite affordable. For DSO's I would definitely want at the least, a 100mm objective and that's a minimum.
Xsauce (2 years ago)
I agree with this.... This is more into the intermediate and advanced level.
ALoonwolf (3 years ago)
Note. The "beginner" would either stick with basic observations, or decide not to continue, or else would progress to a larger telescope, or a different kind of telescope, camera or binoculars suited to what they were interested in. So start small and cheap, then spend your money on your NEXT telescope. Unless you are rich of course.

Hi Very interesting video, not sure about the binoculars, I have a pair of 20x50 and I cant use them, you just cant hold them still enough, admittedly I am 66 and probably got the shakes, although I seem pretty stable, but the images zig zag all over the place, has no tripod mount, in my opinion any reflector under 6 inches, (7.5mm ) is a waste of time if your looking at the planets, image is too small and it drifts across the field of view in about 30 seconds,,,so would need Go To type...best wishes...Fred Essex.

what model was the bins he mentioned?

this helped me out loads thank you x

You're a star cluster diamond in an ocean of dark matter, I know I know, so my magnification went a bit to far. Let me restart: You're a prim lookin' stargazer gril... How's that? @[email protected]

Nice intro...not sure why I'm watching it though. That takes me years back :)

Is there any Exit Pupil Amplification in the Telescope or Binoculars market? Just like Digital camera has lense digital Amplification too. Is that u means, Bigger magnification Eyepieces 66deg/40x=1.65deg FOV. Also plus your Exit pupil will also drop down from 80mm Lense size/40x = 2mm Exit pupil left. Is that correct? 2mm Exit pupil + 1.65deg FOV left? "How to see it in that way?"
rampike74 (6 years ago)
Sometimes you want the magnification, not brightnes. In case of Venus for example, the amount of light that gets to a modest 4 inch mirror is enough for even 200x magnification. So what you want is enough focal length. 1000mm would be ideal, as short focal length eyepieces can produce blurred images. And this is where the equatorial mount comes in. If you're after planets and dwarf planets, like I am, you really want the EQ mount, preferably with a motor, and a long focal length.
