Basics of the Celestron AstroMaster 130

- During the pandemic, a friend asked for some help learning how to set-up and point his new telescope. The German equatorial mount is a bit unintuitive for new astronomers. While the quality is sub-par, here's the video I made for him.
Great video, exactly what I needed to see to finally unbox my 130EQ and get started!
A bit of a background for this telescope:
If this is your first scope, you won't have a point of reference to compare, (and I'm guessing others are in a similar situation) but of all the issues listed the one that'll be "hidden" somewhat is the fact that the primary mirror is spherical at a relatively fast focal ratio.
The mirror is literally incapable of focusing all the light hitting it into a single plane...this means that it's near impossible to resolve fine details...like the cloud bands on Jupiter and the Cassini division in Saturn's rings.
Typically these are the first targets newer folks are excited to see, and then are disappointed and/or think there's something wrong with the scope. You can collimate it within an inch of it's life and thermally acclimate it for hours and the image will still be "soft" compared to a parabolic mirror...which can be had in scopes that cost less.
But I guess many of you would agree with me if you once tried a Dobson, let's say a 6" with reasonable focus length and a real parabolic mirror.
So I say to anyone who has not yet bought it: 'Think twice! There are better options!'
The problem I have with these scopes is that the advertisement makes people dream of things like Astro Photography which just can't come true (Me Too!). There is no long exposure possible with this mount. And the ease of tracking is not worth for visual as it is only a question of a bit of experience to do this with a Dobson or other alt-az mounts so there is no need for the (quite expensive) EQ mount. This money is better spent for the optics. And here the DOBSON can't be beaten, as the mount is extremely cheap AND extremely stable.
The mirror is spherical not parabolic after collimation it was just about bearable. Good enough for the moon for sure . I saw Saturn with it just about but with no detail white/yellow slightly blurry blob with a ring around it. Kind of cool. The stand was extremely wobbly and the legs start to bend out after a while like.it can't take the weight. The focuser teeth also started to break off making focusing a real chore and don't get me started on the motor drive. Planetary photography is also not impossible if that is your end game. You can easily get a tabletop Dobson for the money that will do a way better job than the 130eq.
You say “think twice! There are better options!” What are these options in this price range?
thank you
Wow best review i have got I actually i have one of this and exactly the same thing i have to say you will be disappointed with this telescope especially for new comers to astronomy you might think it will show big saturn rings and stuff but you will be disappointed
I know this is old but I picked this up at costco for around $150 and I think it's good value at that price. I certainly wouldn't pay the $350msrp on it.
@@secret5. If nothing else, it's gotta be a fun learning tool!! I'd pay a-buck-fifty for one of these.
thank you for this video! it took me a lot of time to point at something as big as the moon since i used to randomly point at the sky. those readings are definitely gonna help!
Thanks for the video, I was confused with everything till I found this one, nice and simple to ❤
Thanks! That was an great into! Just got mine and your video cleared up something for me! 👍🏽
Well done, exactly what I was looking for, thank you.
Excelente trabajo y una edición de video profesional.
A nice beginners telescope 🔭
Hi, with same telesvope i dont see very sharp image whether i use 20mm or 10mm supplied eyepuece when i watch objects around like tree leaves at a distance of .5 km. Could something be wrong with its optics?
How do you fit the starpointer??
Thank you for this video
just got one for my Brithday ...ok MARVIN (cartoon from Bug Bunny)
He good? For my Birthday i will get too
Same
Aye me to.
I am also planning to buy one on my bday this year
Same
can you recomend me a better scope thats got a real parabolic mirror and does not have the bird jones issue please. any thing around this price or a bit higher
I like and already subscribed
Thaaaaaank u so much !!! 🙏🙏🙏✌🏼✌🏼✌🏼
Like! Aren't the tripod and mount too weak for this telescope ? Does is wobble / vibrate ?
how do i make it go up and down?
What's the maximum zoom?
I just bought one of these at a garage sale for 40 bucks it was brand-new looking problem is pulling off the clearblue protective film on the equator thingamabob I it caused it to move in relation to the pointer how do I find 0
Great deal!
Do you have any other telescopes?
I teach at Elon University and we typically are using older Meade LX10 telescopes with the students. Here's the tutorial I made for pointing them. ruclips.net/video/cDWIplHKx5c/видео.html
can you tell us, will we be able to see nebula with this
ya u can
Lol no
How do you laser collimate this scope
Idk what you mean
@@jamestropicals8262 Collimation is the process of aligning all components in a telescope to bring light to its best focus. All telescopes need to be collimated at some point; however, it's easy to perform this task on some and a bit more involved for others. There are two types of collimation: optical and mechanical.
Can this do DSO(Deep-Sky Objects)?
Yep! Sorry I’m 5 months late. I’ve heard it’s good for DSOs in low light pollution areas
@@bananabus. don't worry, thank you for telling me. Now I know what telescope to get, and it's Celestron AstroMaster 130.
Do you recommend a 130/650 or a 130/900?
This video isn't meant as a recommendation for the Celestron AstroMaster 130. This video is for those that already have one for some reason or another but are unsure how to set it up and point it.
@@anthonycrider yeah I know, I mean which one's better anyway please?
@@kamelalg9859 they will both gather the same amount of light but the 900 will have a considerable higher magnification. The biggest impact on a better image is to have a parabolic mirror. For about the same price is the Solomark 130eq. It has a parabolic reflector. While I’m not going out on a limb and suggesting that scope, our astronomy club has several of them and ours are very good!!
Bro I’m I have the same model telescope, pointing at the moon rn with a 20mm lens, and I can’t see anything.
This telescope with spherical mirrors with a "short" focal distance, as a result of large spherical distortion, especially with an increase of more than 60-70. I do not recommend buying a telescope (and the like with the short sphere).
I got this telescope aswell
Probably? In astronomy there is NO PROBABLY!
Bro can u help me use it, I set it up but showing nothing
thanks ,i was about to purchase .
LOL
