What does /sci/ think about the ASTROMASTER 130EQ-MD? Is it there a better reflector around it's price?
it's garbage
Get it without the motor drive, the motor drive mount is garbage but the standard EQ mount is great
Overall the scope is good and I adore mine

Had one after falling for the stargazing live meme and sold it.
Was great for the moon, shit for everything else.

lmao

Comes with two lenses iirc and I only used the most powerful one
>>8937122
[math]M=\frac{f_o}{f_e}[/math]
[math]f_o[/math] being the objective focal length and [math]f_e[/math] being the eyepiece diameter
For this scope, the a 10 mm lens it will be
[math]\frac{650}{10}=65[\math]
65x magnification
What you did was buy a scope and magically thought "I should be able to see anything because that is how magnification works right?!"
If you wanted to see small objects you should have gotten a scope with a longer focal length.
A scope like the AS130 is more meant for having a wide aFOV than for deep view with its large objective diameter...like almost ALL Newtonian reflectors

What part about my post did you not understand, brainlet?
What you mean by 'better' is more magnification.
It is not a factor of money, it is the ratio of focal length and eyepiece diameter
Get off /sci/ because you clearly did not understand the BASIC math I posted
There are cheaper scopes with a longer focal length giving them a GREATER magnification.
Like my PS70 which has a 700m focal length and cost 130$, thus more magnification than the 650mm AS130. Though its useful magnification is far lower because it is a refactor.
Greater magnification[math]\neq[/math]better scope
I have a AS130, a PS70, and a home built dobsonian

What can you see with your PS70 mr angry?
>>8937362
Are you still not understanding what is that I am saying? Are you south american or something?
Let me put it to you this way, pic related is the AS130 with a 4mm eyepiece and a 3x barlow. This is basically the highest useful magnification of the scope.
You do not understand the basics of optics and complaining when the results are bad because you thought it was a matter of money
Stellarium is accurate with its view simulations
>>8937378
OR to put that into math [math]M=\frac{650}{5}\cdot3[/math]
Also I meant a 5mm eyepiece, the 4mm eyepiece overextends its useful magnification
>>8937362
To clarify even more, you were using a 10mm eyepiece
[math]M=\frac{650}{10}=65[/math]
When you should have been using [math]M=\frac{650}{5}\cdot3=390[/math]
Mars is a very small planet and requires quite a lot of magnification, but you are too much of a brainlet to understand these concepts...so trot back on to your south american engineering classes and stay off /sci/
