Thor’s Helmet (nebula) captured using a tracking telescope mount without the use of autoguiding. The bottom line is, the longer you shoot for, and the higher the magnification used – the more guiding can help. Aside from capturing several images using short exposures on the RASA 8, I ha...
That's when a star starts to fuse helium into carbon, and becomes a red giant. It's not a very exciting transition; no explosions or anything. But the core becomes much hotter, which puffs up the star's size immensely, so paradoxically the outermost layer actually becomes cooler, glowing ...
The energy that a star produces is a direct result of what type of process? (a) Nuclear fission (b) Thermal irradiation (c) Nuclear fission (d) Thermal expansion (e) Nebula convection What are nuclear forces? What is the big deal if a nuclear reactor melts down? What happens? W...
Explain the difference between intensity and solar constant. Explain the terms, Radiation and Blackbody Radiation. What is the distinction between a nebula and a galaxy? What is dark energy? Define ultraviolet telescopes. What is the difference between absorptive power and spectral absorptive power?

Nebula, the globular M79, and Jupiter (including a shadow transit). He was "amazed" that a well-made 6" approached the performance of a quality 7-inch Star Fire refractor. But he also felt that "many amateurs would be quite happy" with the performance of the 1/2 wave scope. (Near ...
What distinguishes a nebula and a star? Why is the distance to planetary nebulae important? What is planetary astronomy? What is space velocity in astronomy? What is ephemeris in astronomy? How are geology and astronomy similar? What is a quasar in astronomy? What is stellar astronomy? How a...
I am unable to determine the difference between the Lumicon UHC and Lumicon Deep Sky filters. The product description of the Lumicon Deep Sky filter says its Lumicon's "most popular nebula filter" and claims the same stuff as the UHC. So what is the difference then between the UHC ...
An example of accretion in astronomy is when a star forms from the gravitational attraction of gas and dust in a nebula, causing these materials to accrete and increase the star's mass. 15 What does it mean to accumulate something? To accumulate something means to gather or collect items or...
Nebula (astronomy) A cloud in outer space consisting of gas or dust (e.g. a cloud formed after a star explodes). Common Curiosities Are all nebulae visible to the naked eye? No, most nebulae can only be seen with telescopes; a few, like the Orion Nebula, are barely visible to the ...
