Another type of diffuse nebula, a reflection nebula doesn’t emit its own light, but scatters light from embedded stars. (Image credit: NASA, JPL-Caltech, Kate Su (Steward Obs, U. Arizona) et al.) Planetary nebula: The Helix Nebula This is composed of expanding gas that was blown off...
emitting a circumstellar shell of hydrogen gas. When this phase comes to an end, the star enters the PPN phase, where it is energized by a central star, causing it to emit strong infrared radiation and become a reflection nebula.
Nebulas are giant areas of dust and cloud that can be put into one of five groups: star forming, reflection, planetary, supernova remnant and dark.
emission nebulae, reflection nebulae, dark nebulae and supernova remnants. I will cover the planetaries in the next chapter and discuss the other four types here. Even though all these objects appear as fuzzy and diffuse in the telescope, there are different mechanisms at work among the differin...

If you want a good filter for stars and galaxies, and comets, and dark nebulae, and reflection nebulae, it's gasoline. You put it in your car and drive your scope to darker skies. Edited by Starman1, 07 April 2023 - 05:12 PM. ...
Only downfall - it is limited to emission nebulae. Broadband targets such as galaxies or reflection nebula still require LRGB. choward94002, on 03 May 2023 - 12:11 PM, said: You also need to calculate individual exposure times for each filter, as most objects are strong in one wavelength...
Stellarium is a free GPL software which renders realistic skies in real time with OpenGL. It is available for Linux/Unix, Windows and macOS. With Stellarium, you really see what you can see with your eyes, binoculars or a small telescope. - mhdZhHan/stel
