Description

Probably the last image I take with my 8SE for a while, as it struggles with coma when using a reducer. Finally received my William Optics GT102 that I have had on back order for some time. I am super excited to get out under the stars and give it ago! No doubt it will become my primary imaging scope. Now if the clouds and rain would just go away!
