Messier 108 is a great example for why we call it Galaxy Season. At this time of year, many of the beautiful galaxies that grace our night skies are high above us.
Because you’re shooting straight up, you’ve got much less air to contend with and ultimately get a sharper photo. And with few neighbours around due to the lockdown and a moon that won’t rise for a few hours I had lots of time to take the Surfboard out for a spin.
After a few nights of imaging galaxies with 3 minute exposures, I’ve decided to reduce the time to 120 seconds tonight. In attempts to bring out faint outer rings I’ve been blow out the core and I wanted to ensure I captured more of the detail in the dust blocking the 46 million year old light.
My efforts were successful, as you can see the bright red and yellows of the core while still getting the blueness of the gas arms. Stars in this photo have a natural colour – something I keep blowing out when I over expose in others.
Sequence Generator Pro has been having issues with my focus motor lately, and tonight has been no exception. Even though it hasn’t stopped me imaging I’m worried I’m not getting the exact focus I should be. Astrophotography can sometimes be 1 part stars and 2 parts dealing with technical issues. Nothing could ever work perfectly, can it?
