What is a hydrogen-alpha telescope?

What is a hydrogen-alpha telescope?

H-Alpha Telescopes are used to observed the sun in high resolution. With an solar telescope like this, you will be able to see, sun spots, surface details, prominences and striations.

What is a hydrogen-alpha filter?

An H-alpha filter is an optical filter designed to transmit a narrow bandwidth of light generally centred on the H-alpha wavelength. This combination will pass only a narrow (<0.1 nm) range of wavelengths of light centred on the H-alpha emission line.

What color is H-alpha?

red
That color of red is called the hydrogen-alpha (or H-alpha) band. It is emitted by hydrogen atoms, the main constituent of the Sun. This picture was taken near the peak of the sunspot cycle (Solar Max) when the Sun was very magnetically active. Several solar filaments are visible in this image (dark lines or curves).

When we look at the Sun through a filter centered on the HΑ line we see?

Hα is reddish-colored light with a wavelength of 656.28 nanometers (nm). Through an Hα filter, which allows only Hα light through, you’ll see prominences, bright gas clouds ejected from the Sun and shaped by its magnetic field.

Why are H-alpha filters so expensive?

Using it they have to put spaces in it and the closer the spaces are together the more it costs and better it performs. Also a lack of competition (I think there 3 major H-Alpha filter distributors. Coronado and Thousand Oaks, DayStar, any more? ) So they pretty much set the price.

What do I need to photograph the sun?

How to photograph the Sun: the basics

  1. When photographing the Sun you will need to use a special solar filter.
  2. A large size lens or telescope can give good details and a tracking mount is helpful.
  3. The best time to photograph the Sun is early morning, before the atmosphere becomes heated and unstable.

What is H gamma?

As the first spectral lines associated with this series are located in the visible part of the electromagnetic spectrum, these lines are historically referred to as “H-alpha”, “H-beta”, “H-gamma”, and so on, where H is the element hydrogen.

What are the two main parts of the Sun?

There are three main parts to the Sun’s interior: the core, the radiative zone, and the convective zone. The core is at the center. It the hottest region, where the nuclear fusion reactions that power the Sun occur. Moving outward, next comes the radiative (or radiation) zone.

How do H-alpha filters work?

H-alpha filters work by rejecting all but the narrow sliver of H-alpha light. The narrower the filter wavelength, the more off-band light is eliminated and the greater the contrast, all crucial factors for seeing details in the chromosphere.

Is it OK to take a picture of the sun?

Photographing the Sun can be perfectly safe, as long as you take the proper precautions. You can use these techniques to photograph the November 11th transit of Mercury. Photographing the Sun is not usually the first idea that pops into your head when you hear the word astrophotography.

Is it OK to point a camera at the sun?

We have all glanced at the sun, but prolonged exposure causes permanent damage. DO NOT point a camera at the sun unless the optics are fitted with a certified solar filter. Optics can magnify the intensity and brightness of sunlight, and this can cause damage to your equipment.

How to view the Sun in hydrogen alpha light?

Observe the Sun in the crimson light of hydrogen alpha (h-alpha), and watch it come alive. Eric Norland of Lakewood Township, Minn. uses a portable Coronado Solar Max 60 telescope designed for viewing the Sun in hydrogen alpha light.

How big is a hydrogen alpha solar telescope?

This is through a SolaREDi 0.5 angstrom 35mm aperture Hydrogen Alpha telescope: This is through a prototype 5 angstrom Calcium II H line SolaREDi: March 24, 2008: Active Region 10987 Things are hopping again after a long lull in activity; this is active region 10987 through various filters on a 6″ refractor.

How big are the images on hydrogenalpha.com?

The camera fed the images (2056×2062 pixels, 12fps) over a gigabit ethernet connection to a PC with a flat screen display on the booth table, where they were automatically colorized and displayed in real time.

How is the H-alpha solar filter adjustable?

The heater here is adjustable, so the viewer can examine Doppler-shifted features in moving solar material by adjusting the knob pot to examine to the object either blue-ward or red-ward of centerline. With sophisticated optical components, some made of quartz, and temperature controls, it’s no wonder H-alpha filters aren’t cheap!
