Details:
So how do you make magnitude 18.5 Comet C/2018 F1 Grauer look good with magnitude 10 Spiral Galaxy M88 in the background, you don't, not if you want to show a little detail in M88 and still see Comet Grauer.
Comet Grauer is 268 million miles from Earth in this image. It will reach perihelion December 14 when it will be 278 million miles from the Sun. It may reach magnitude 18 in early 2019. If one is patient and healthy the comet will be back in 5,667 years unless something perturbs its orbit between now and then. At aphelion the comet will be 59 billion miles from the Sun, Pluto is only 3 billion miles from the Sun.
