This was a 5-min exposure with a number of 30 exposures totaling 150-minutes total time exposed. I used a program called Nebulosity to capture, stack, and process 30 frames including 30 dark frames. This is a guided image using a Celestron 11" HD and CGE Pro Mount, piggybacking with a Orion 80 refractor using an Orion autoguider.
You see some detail in the galaxy, but I'm still a novice and post processing with different programs like Photoshop. Seeing conditions, transparency, and other variables affect the image including other atmospheric conditions (I'm not in space, I have to look through the Earth's atmosphere). There are several galaxies in the same location as M98. M98 is in the constellation Coma Berenecies and is a spiral galaxy about 60 million light years away.
