Do you need an equatorial mount for astrophotography?

Your equatorial mount is the #1 most important item for astrophotography of deep-sky objects. The mount should always be the most expensive part of your setup. If you can afford nothing but a mount, just get an adapter and put your DSLR or lens on if you can, then upgrade to a scope later..

Is an equatorial mount worth it?

These mounts are good for terrestrial observing and for scanning the sky at lower power but are not for deep sky photography. It can track continuously across the meridian, which many German mounts cannot do. Because it has very little or no counterweights, it’s also lighter and more portable.

What is a rotator in astrophotography?

A camera rotator is a rotation unit that installs between the telescope OTA and the camera. Today several camera rotators are available to amateur astronomers. Camera rotators or instrument rotators as they often are called, are used on all major professionel telescopes.

Which is better alt-azimuth or equatorial?

Alt-az mounts are considered superior for visual astronomy because they provide such comfortable viewing positions at the eyepiece. Many experienced visual astronomers recommend alt-az mounts for this reason. All in all, equatorial mounts are designed with the astrophotographer in mind.

Can you use an Alt-Az mount for astrophotography?

If you own an Alt-Az mount, you most likely think “It cannot be used for deep sky astrophotography”. But that is not correct. It is possible to take wonderful deep sky images with an Alt-Az mount if you know how to do it and pick the right objects.

Can you autoguide an Alt-Az mount?

I want to autoguide with my Alt-Azimuth mount for long-exposure astrophotography. Will this work? Technically, yes, it will work. Many modern autoguiders can keep up with the guide rates involved.

Can you track with an Alt-Az mount?

The mount can be setup without any leveling of any kind. When powered up, the mount is aligned on two known objects creating the information needed for precise tracking of the sky. Based on that information, a basic Alt-Az mount can track a single object across the sky with great precision.

What is field rotation in astrophotography?

Field rotation is the apparent rotation of a celestial object in the field of view of a telescope during the course of the night. All objects in the eyepiece field or on the camera’s image will move in arcs. It’s usually either ignored or not noticed for visual observations, but cannot be ignored for photography.

Is the Hubble Space Telescope still the largest scope ever built? Hubble Space Telescope is still the largest scope ever built. The most important advantage of CCDs over film is that: they record much more light in a given exposure time. Refractor telescopes suffer from this separation of light into its component colors.

Why are refractors better for astrophotography?

Refractors are compact and lightweight compared to other telescope designs. The focusers are solid and easy to focus. They offer a similar experience to a high-end telephoto camera lens. The image quality potential for astrophotography is exceptional.

What is the most important advantage of CCDs over film?

The most important advantage of CCDs over film is that: they record much more light in a given exposure time.

What size telescope do I need to see the rings of Saturn?

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.

Are reflectors better than refractors?

Refractors generally have the edge over reflectors for a quality image, both from the standpoint of lens/mirror quality and precision optical mountings, and lack of central obscurations. Equally important in a choice of telescope type is the focal length and the resulting field of view.

Which telescope has the least complicated light path?

The simplest reflector telescope design is the prime focus reflector.

How much more times the light gathering power does A telescope with A 12 inch diameter objective have than A telescope with A 3 inch diameter? A 12-inch telescope would gather (12/6)2 = 4 times as much light as the 6-inch and (12/3)2 = 16 times as much light as the 3-inch.

Is it possible to see Neptune and Uranus with a telescope? To catch a glimpse of Neptune, you’ll need a telescope of at least eight inches of aperture at about 100x to 150x magnification. With equipment like this, you’ll still need steady skies to observe this tiny bluish disc. As with Uranus, do not expect to see any surface features or its faint rings.

How strong of a telescope to see the flag on the Moon? The flag on the moon is 125cm (4 feet) long. You would require a telescope around 200 meters in diameter to see it. The largest telescope now is the Keck Telescope in Hawaii at 10 meters in diameter. Even the Hubble Space telescope is only 2.4 meters in diameter.

What the difference between an equatorial mounts and Alt Azimuth?

Computerized equatorial mounts and alt-azimuth mounts both track the motion of the stars and celestial objects, but they do so in different ways. Alt-azimuth mounts track in iterative up/down – left/right movements. Equatorial mounts are essentially alt-azimuth mounts but tilted at an angle based on your GPS longitude.

Is a Newtonian telescope good for astrophotography?

The 8” f/3.9 Newtonian Astrograph is a nice astrophotography telescope – and a surprisingly good one for visual use as well. It’s a surprisingly affordable and good scope for astrophotography.

What are the advantages of equatorial mount?

The advantage of an equatorial mount lies in its ability to allow the instrument attached to it to stay fixed on any celestial object with diurnal motion by driving one axis at a constant speed. Such an arrangement is called a sidereal or clock drive.

What is the purpose of an equatorial mount?

Since the sky rotates (or appears to) around the north celestial pole, the mount also has to be aligned to this axis of rotation to track the stars’ movement. Equatorial mounts are designed to be polar aligned – if you don’t bother, you might as well have saved your money and bought a cheaper altazimuth mount.

Can you use an alt-az mount for astrophotography?

If you own an Alt-Az mount, you most likely think “It cannot be used for deep sky astrophotography”. But that is not correct. It is possible to take wonderful deep sky images with an Alt-Az mount if you know how to do it and pick the right objects.

What is a field Derotator?

A field derotator is used with an tracking Alt-AZ mount for long exposure astrophotography. As you track across the sky with an ALT-AZ mount, the stars not only translate from east to west but the field rotates. With a Equatorial mount the telescope also rotates as it tracks so it is the ideal mount for photography.

Are iOptron mounts good?

The iOptron CEM60 is a center-balanced equatorial telescope mount that provides an excellent platform for visual astronomy and astrophotography. What makes the iOptron CEM60 computerized telescope mount so special is its impressive weight to payload capacity ratio and the now famous “Z-shape” design.

What does alt azimuth mount do? An altazimuth mount or alt-azimuth mount is a simple two-axis mount for supporting and rotating an instrument about two perpendicular axes – one vertical and the other horizontal. Rotation about the vertical axis varies the azimuth (compass bearing) of the pointing direction of the instrument.

How far can a 70mm telescope see?

With a 70mm telescope, you will easily be able to see every planet in the Solar System. You will also be able to take a great look at the Moon and clearly distinguish most of its recognizable features and craters.
