I just bought Celestron AstroMaster 130EQ Telescope APERTURE 130mm, FL 650mm, FR=5 and it comes with 10mm lens and 20mm lens. first do i need Celestron Ultima 1.25 in 2x to get closer images, second i just bought this one and i can exchange it with Celestron AstroMaster 114EQ 1000mm APERTURE 114mm FR 8.77 or keep the 130EQ?
Firstly, I'm not familar with either scope so I couldn't really give much of an informed opinion. I'd suggest taking the first one out now and seeing if you're happy with it or alternatively, see if a local astronomy club is having an open night soon and see if they have similar scopes.
Secondly, the "1.25 in 2x" sounds like a barlow lens. That will effectively double the magnification of the current eyepiece which will give you 'closer images'.
with that aperture you could get a maximum magnification of 260 ( aprox 2 times the diameter of the main mirror),
to get any magnification divide 650mm (focal distance) by the eyepiece to use, for example 650mm/10mm= 65x , and 65x 2 (2x barlow magn)= 130x so that´s a good magnification to see Jupíter and it´s 4 main moons or the Saturn Rings well. Even with a 3x Barlow Lens you could get 195x , allways respect the limits of the main mirror of your telescope
The larger one on the right (called Rupes Recta) is a fault line. The smaller one to the left is a rille, possibly a lava channel or collapsed lava tube.
nice images

Easily the best view of Plato I have ever seen. Keep up the good work. These are easily the best pictures of the moon on youtube.

@Dubai1976 Hey, look:

what about Neptune or Uranus?
mattanator21 3 years ago
Yup, seen/imaged both of them as well. I actually imaged Uranus on the same night that I captured the images for this video.

chrissy are you able to look at venus or mercury through your telescope? or are they too close to the sun?
mattanator21 3 years ago
Sure, I've viewed and imaged them both before.

Are the trails caused by a rolling bolder or are they just fault lines?
