Description

This is the third supernova in M108 since 1969. The newest supernova was reported on March 13th and I was able to capture it from my backyard on March 19th. 

A new supernova was reported by the Zwicky Transient Facility on March 13th. I didn't have any plans on imaging M108 this year because I already have a shot last year but I couldn't miss this opportunity. I pointed my telescope at the galaxy for 2 hours to see the tiny bits of light appear in my image. I'm hoping it gets brighter over the coming weeks and I get another chance to shoot it again. 

I made a quick video comparing an image of  M108 from last May with the one taken a few days ago plus info on my equipment and acquisition details. You can find it here: https://www.youtube.com/watch?v=0BmnD7vLNTc
