telescopes with larger apertures are recommended because they collect more light. Newtonian reflectors are a great choice for those on a budget and can pull in some tremendous details on thebrightest galaxiesin the night sky.
However, now you are aware of heat haze, there are some steps you can take to mitigate and avoid blurry images. First, if you are shooting when there is heat haze you need to try and minimize the impact it has on your photos. The best option is to reduce the distance between yourself...

Pleochroism Table.Light passing through some crystals is absorbed differently in different directions. Commonly, different wavelengths of light (colors of light) are absorbed different amounts in different directions. ... Thus, a consequence of pleochroism is that stones look different colors in dif...
then extract the position of some body along its orbit at a time of interest, and calculate where that position would appear as seen from Earth by allowing for the finite propagation speed of light from there to here. It seemed incongruous to allow for the finite speed of light from the ...
Whenever someone suggests it, I always want to go out for dinner. The thought of it makes me high. There are consequences, however, to going out to eat every time I have the impulse—potentially serious, long-term ones, both financial and subcutaneous. But dining out is such an ever-exc...
