Astrophotography with Astromaster 130EQ
Neither the CG-3 mount nor the AstroMaster’s focuser are heavy duty enough for astrophotography with a DSLR, though webcam planetary imaging is in theory possible with a 3x or 5x Barlow lens coupled to the optical tube..

What is a Barlow lens for a telescope?
A Barlow lens is an optical tube containing lens elements that diverge the light passing through them. Advertisement. Named after English physicist and mathematician Peter Barlow, Barlow lenses add a second lot of magnification to each of your eyepieces while maintaining the existing eye relief.
Is the Celestron AstroMaster 130EQ a Newtonian telescope?
Celestron – AstroMaster 130EQ Newtonian Telescope – Reflector Telescope for Beginners – Fully-Coated Glass Optics – Adjustable-Height Tripod – Bonus Astronomy Software Package.
What does EQ stand for in telescopes?
EQUATORIAL (EQ)
The Equatorial mounting (more properly called a German equatorial mount or GEM but most often referred to as an EQ) is the standard mounting for many types of telescope. The advantage of a standard equatorial mount over an Alt/Az is that the mounting is designed to track the motion of the stars.
Is AZ better than EQ?
As the Earth rotates around its axis, the stars appear to move across the sky. If you are observing them using an Alt-Az mount, they will quickly drift out of view. A telescope on an EQ mount can be aimed at a celestial object and easily track the daily motion, keeping it in your eyepiece.
What size telescope is best?
As a rule of thumb, your telescope should have at least 2.8 inches (70 mm) aperture — and preferably more. Dobsonian telescopes, which are reflectors with a simple mount, provide lots of aperture at relatively low cost. A larger aperture lets you see fainter objects and finer detail than a smaller one can.
How do you use an EQ telescope?
What size eyepiece is best for viewing planets? The focal length of the telescope is 900mm, so to achieve the maximum useful magnification, then a 4.5mm eyepiece would be ideal. One of the best parts about planetary viewing or imaging is that since the objects are so bright, you can do it just about anywhere regardless of light pollution.
Which telescope is best for viewing planets and galaxies?
- Orion GoScope 80 Tabletop.
- Celestron StarSense Explorer LT 114AZ.
- Vaonis Stellina Observation Station & Hybrid Telescope.
- Celestron PowerSeeker 127 EQ.
- Orion StarBlast 6i IntelliScope.
- Encalife SVBONY 501P 70.
- Celestron NexStar Evolution 9.25.
- Sky-Watcher Skymax 127 SynScan AZ GoTo.
Which Celestron eyepiece is best for viewing planets?
Ultra-short focal length (2-4mm) eyepieces provide very high power magnifications and are best for observing the planets and the moon on shorter focal length telescopes.
What can you see with a 90mm telescope?
What can you see with a 90mm telescope?
- The Moon: easy to see mare (ancient lava plains) and craters on the lunar surface.
- Andromeda Galaxy (autumn): about 2.5 million light-years away and the closest large galaxy to our Milky Way.
What kind of telescope do I need to see Mars?
Any telescope will work for Mars, but the bigger, the better. A 4-inch refractor or a 6-inch reflector are the recommended minimum. Apply high power (175× or more), and wait for a night with steady seeing, when the Martian disc is not blurred by turbulence in our atmosphere.
Which eyepiece is best for viewing stars?
Plössl eyepieces are excellent for general use although their eye relief will diminish as the eyepiece’s focal length reduces. This design is most suitable for observing nebulae and star clusters. A 15mm and 25mm Plössl eyepiece would be good additions to your current line-up.
What is the best eyepiece to view Jupiter with? Best eyepiece for viewing Jupiter
Jupiter looks best in the 100x-200x range for enthusiast-level telescopes.
How good is a 90mm telescope? The optics in the AstroView 90 are exceptionally good – a cut above a lot of the cheap achromatic refractors. I have been impressed by the views through these scopes. The AstroView 90 is also well-baffled and has decent interior paint, along with an ample-length dew shield. Stray light and glare are not issues.
Can you see nebula with a 90mm telescope? 60mm (2.3in) to 70mm (2.8in) aperture or equivalent
See below additional details of the other celestial sky objects you’ll be able to see with an aperture size between 90mm (3.5in) to 130mm (5in). c) Deep Sky Objects: dozens of globular clusters, emission nebulas, planetary nebulas, and galaxies.
What is the focal length of Celestron Astromaster 130?
Celestron 130EQ Specs
| Optical Design | Newtonian reflector |
|---|---|
| Aperture | 130 mm |
| Focal Length | 650mm |
| Focal Ratio | f/5 |
| Eyepiece Barrel Diameter | 1.25″ |
What size telescope do I need to see Saturn’s rings?
Viewing Saturn’s Rings
The rings of Saturn should be visible in even the smallest telescope at 25x. A good 3-inch scope at 50x can show them as a separate structure detached on all sides from the ball of the planet.
What is EQ telescope?
EQUATORIAL (EQ)
The Equatorial mounting (more properly called a German equatorial mount or GEM but most often referred to as an EQ) is the standard mounting for many types of telescope. The advantage of a standard equatorial mount over an Alt/Az is that the mounting is designed to track the motion of the stars.
Which eyepiece is best for viewing planets?
Ultra-short focal length (2-4mm) eyepieces provide very high power magnifications and are best for observing the planets and the moon on shorter focal length telescopes.
Does a Barlow lens decrease quality?
Actually, it doesn’t depend much on the Barlow. All Barlows dim the image in line with the increase in magnification. Back in the 70s and 80s Televue produced a 1.8x Barlow that did dim the image compared to the same magnification produced without the Barlow.
Is a Barlow lens worth it?
Every amateur astronomer should consider the Barlow lens as an extremely useful tool. One of the greatest advantages of say, a 2x Barlow Lens is that it doubles the magnification of your eyepieces, which can also be effectively seen as doubling your eyepiece collection.
Does the Celestron AstroMaster 130EQ have a parabolic mirror?
Designed for near and deep-sky observation with a fast focal ratio for astrophotography/imaging, Celestron’s AstroMaster 130EQ 130mm f/5 Reflector Telescope features a 650mm focal length and an oversized parabolic mirror that produce detailed images of the Moon, clear views of the planets, and the ability to resolve
How much magnification is 130mm telescope? The “maximum” magnification is just a number, usually around 60 times the aperture [in inches]. In this case: 130 mm / 25.4 mm per inch = 5.12 times 60 = 307x magnification.
Is a 90mm refractor good?
The Orion Astroview 90mm refractor is an ideal telescope for novice astronomers ready to invest in their first model. There are some shortcomings, but this affordable telescope offers the laser-sharp optics that refractors are known for and is ideal for your first views of the Moon, planets, and stars.
